Pump Industry Spring 2021

Hello all and welcome to the Spring Edition of Pump Industry Magazine the official voice of Pump Industry Australia, and thanks to those few who pointed out to me that the last edition mistakenly read the Autumn Edition - as if we would want to go through winter again.

I would like to say that with the advent of spring everything should be looking up, but am forced to admit that 2021 is turning out to be no better than 2020, as the recent outbreaks of the Delta variant across Australia and now New Zealand has introduced a high degree of uncertainty to the outlook for the second half of the year.

time to review and update what you currently have. Discount is available for bulk purchases.

Some information that will be of interest to QLD Members is that a subcommittee of PIA has approached the QBCC with a view to getting a better understanding of the QLD Legislative Acts defining works related to water and sewage installations and repairs covered by the Plumbing and Drainage Act 2018 (PD Act).

The pathway to improved work and lifestyle beyond the pandemic is vaccinations. Unfortunately, distribution and vaccine hesitancy have been major issues to getting the vaccine. Hopefully we will see new supplies speed up the rollout, reducing the frequency and severity of lockdowns. However, the recent outbreak will depress economic activity in the September Quarter, resulting in negative growth of somewhere between zero and one per cent instead of increasing by a similar amount. We know the Australian economy is quite resilient and hopefully we will see the economy rebound in Q4 as vaccinations increase and restrictions ease as it has done after previous lockdowns. The key is getting the vaccinations up to the 70 per cent or 80 per cent threshold so we can do away with lockdowns and open up both the economy and the country’s borders.

Meanwhile on the domestic front, PIA activities have been very subdued because of the current lockdowns. It is hoped we can hold another of our Pumps & Training Systems Courses in Perth in September, COVID permitted, so for all our WA Members please watch the Thursday weekly news releases from Monkey Media for more information. The July breakfast seminar planned by DAB Pumps Oceania in Melbourne was postponed.

You may have noticed recently in Monkey Medias’ weekly newsletter reference to our two Handbooks specifically designed for the Australian pump industry – the Australian Pump Technical Handbook and the Australian Pipe Friction Handbook, both in their fifth editions. These publications are industry standard reference volumes for those who work or are associated with the pump industry including consultants, designers, manufacturers, distributors, operators, users and educators. Both these publications have been recently updated so now might be a good

Our belief is that the Legislation relates more to the public health arena rather than mining, petrochemical, industrial process, marine, energy, stock water, irrigation, fire protection, golf courses, etc. but we seek further clarity regarding water and sewage work.

As you know, our industry consists of several hundred small to large enterprises employing thousands of people across the sector and this matter is extremely important to them. The initial response from the QLD Government to our request was both positive and helpful; we understand that this dialogue has a long way to play, but PIA will keep you up to date with events as they occur.

As the opportunity allows and we see a return to some form of normality, we plan to run two or three seminars in the coming months on topics of interest to the industry. In the meantime, please feel free to put forward any topics or discussion points you would like to see raised.

Even in these difficult times we are fortunate to be able to stay connected through our Pump Industry Magazine, which continues to be well subscribed to, providing excellent editorial and coverage of newsworthy events in our industry. In addition, there is the weekly e-newsletter which provides you with all the latest news and developments as they occur. I trust you find the quarterly magazine and the weekly news releases as a great way of remaining connected to the industry at large and a distinct benefit of your membership.

At the time of writing NSW, VIC and NZ were all in lockdowns, so I am hoping that by the time you get to read this edition the lockdowns will be lifted, the vaccination rates approaching the 70 per cent mark and we start to see some light at the end of the tunnel and a return to see some sort of normalcy. So for the good of all the community please get vaccinated and stay safe.

Best Regards

John Inkster President

SMART PUMPS

Mitiamo pipeline project reaches completion

The Federal and Victorian Governments have announced that the Mitiamo Pipeline Project has been completed, supplying more reliable water supply and less water evaporation to irrigators across the state.

Deputy Prime Minister and Minister for Infrastructure, Transport and Regional Development, Barnaby Joyce, said the completion of the Mitiamo and District Water Supply project came as part of the $3.5 billion National Water Grid which aims to secure Australia’s water future.

“This project is fantastic news for the local economy which is strongly backed by agriculture, with project construction also having supported 170 jobs here in regional Australia,” Mr Joyce said.

The completed project includes 300km of new pipeline which will supply a new district covering in excess of 58,000 hectares of land north of Bendigo and southwest of Echuca, helping to provide a year-round service to around 170 rural properties.

Historically, more than 80 per cent of water supplied via the channels in the region is lost before use and only two-thirds of the project area is currently serviced, with farmers incurring high water cartage costs.

Victorian Acting Water Minister, Richard Wynne, said the project will reduce public and private water losses by more

than 1,000ML per year by replacing the old leaking channel with pipes, a pump station and 85ML storage facility to provide year-round water supply.

“A lack of reliable, quality water has constrained the expansion of agriculture in the Mitiamo region – this project will address this and help farming grow in northern Victoria,” Mr Wynne said.

Water saved will be used to improve the health of rivers and wetlands in line with Victoria’s obligations under the Murray Darling Basin Plan, with no socio-economic impacts.

Federal Member for Mallee, Anne Webster, said with around a gigalitre of water savings to be achieved each year, the completion of this project allows farmers to invest with certainty for the future.

“This is a fantastic project that will support agricultural benefits for farmers through improved stocking rate and livestock productivity,” Dr Webster said.

“The completion of this project is great news for the local communities, as it will provide a secure and stable water supply.”

The Mitiamo and District Water Supply Project received $14.5 million from the Federal Government, $10.2 million from the Victorian Government and $4.3 million from Goulburn Murray Water.

$77 million for Rockhampton water and sewerage infrastructure

Rockhampton Regional Council has allocated $77 million over the next three years for water and sewerage infrastructure in its latest Budget.

Rockhampton Mayor, Tony Williams, said the next three years would see the Council invest heavily in essential infrastructure so that the services are in place for more housing, more industry and more people calling Rockhampton home.

“This Budget contains a major investment in three catalyst infrastructure projects – the North Rockhampton Sewage Treatment Plant (NRSTP), the Gracemere Sewage Treatment Plant (GSTP) and the Glenmore Water Treatment Plant (GWTP),” Mr Williams said.

“These projects are the key to unlocking a bigger and better Rockhampton because they allow us to service an additional 16,000 homes.

“Without them, we’ll find ourselves constrained to grow substantial new housing development in as little as three years.

“At the same time, economic modelling predicts these projects will create a benefit to the local economy with 300 local jobs generated and $107 million added to the local economy.

“We have already received some support from other levels of government towards these projects but, given the cost and the benefits they will deliver to our region, we will keep talking to them to see how we can partner on these projects going forward.”

Rockhampton Water Councillor, Donna Kirkland, said these upgrades would deliver not just bigger services, but better ones.

“As part of the sewage treatment plant upgrades, we’ll be changing the style of aeration during the treatment process,” Ms Kirkland said.

“This will mean that the process of treating the sewage is more effective and energy efficient resulting in lower energy cost.

“These three projects are all at different stages with the NRSTP design completed and set to go to tender in the coming months for commencement of construction before Christmas.

“The Gracemere STP project will commence a detailed design stage in the coming months and the Glenmore WTP

Upgrade Project is already underway with the project awarded to Alliance Automation for the completion of a design and construct project.

“Expenditure on all three projects is expected to ramp up significantly over the next 12 months.

“About 65 per cent of the connected population in Rockhampton relies on the NRSTP day in, day out, and it is approaching its design capacity now.

“That’s why we’ll be looking at progressing this one first, with the

upgrades set to increase capacity by 50 per cent, meaning it will be able to service 75,000 people alone.

“I’m also very pleased that these projects will drive better environmental outcomes – less nutrients and effluent will go back into the environment, reduced carbon dioxide emissions through energy efficiency gains, and we expect to see more opportunities for reuse of treated water in irrigation.”

New pump station to be constructed for $3.5 million project

Construction of a new sewage pump station at Hallidays Point began in early August as part of a $3.5 million project that aims to increase the operational efficiency of the region.

The new pump station will allow for sewage to be diverted from a number of nearby pump stations and transferred directly to the Hallidays Point Sewage Treatment Plant via a new rising main.

The New South Wales Midcoast Council’s Director of Infrastructure and Engineering Services, Rob Scott, said,

“This will reduce the volume of sewage the existing pump stations are required to process, giving our system more local capacity.

“As a result, we won’t need to upgrade these pump stations to keep up with future growth in the area, and there’ll also be less chance of any sewage overflows occurring during wet weather events.”

Mr Scott said a permanent generator would also be installed at the new pump station to protect against power outages, and an odour control system would be put in to ensure the community didn’t experience any unwanted odours.

While the work will take place close to Blackhead Road, there will be minimal disruption to traffic or the community.

The project is expected to be completed by March 2022.

$20 million federal funding to improve TAS water security

As part of the $108 million National Water Grid Connections funding pathway, the Tasmanian Government has received $20 million in federal funding for four water projects to improve water quality and efficincy, including upgrades to sewerage pump stations, and water and irrigation scheme expansions.

These four new projects will each receive $5 million of federal funding to deliver enhanced water reliability while also promoting regional economic growth and sustainability.

The successful projects are:

• $5 million for the augmentation of the Greater Meander Irrigation Scheme

• $5 million for Shellfish Lease Water Quality Improvement Program to upgrade sewerage pump stations close to shellfish lease areas

• $5 million for an expansion of the Penna Recycled Water Scheme

• $5 million for the South Arm Recycled Water Pipeline, which is a reuse scheme to deliver irrigation water to the South Arm Peninsula

The National Water Grid Connections initiative is designed to deliver the construction of smaller-scale projects to provide short-term economic stimulus, and to support primary production and unlock potential in regional communities.

Up to $20 million was made available for each state and territory to deliver projects over the next two years, with an Australian Government contribution of up to $5 million per project.

Assistant Minister for Industry Development, Jonno Duniam, said the Government was delighted to support the

South Arm Recycled Water Pipeline in Tasmania, which will transfer water from Blackmans Bay Water Treatment Plant to the South Arm Peninsula.

“The pipeline will improve the resilience and reliability of South Arm’s water infrastructure, ensuring a stronger future for water security across the region,” Mr Duniam said.

“It will strengthen the local economy of South Arm, support agricultural production and lead to new investment in economic activities in the region.”

Deputy Prime Minister and Minister for Infrastructure, Transport and Regional Development, Barnaby Joyce, said through this funding pathway, the Australian Government is investing in packages of water infrastructure projects brought forward by states and territories right across the country to improve water reliability and efficiency.

“The National Water Grid Connections is all about driving the construction of smaller-scale projects over the next two years to provide short-term economic stimulus,” Mr Joyce said.

“The cumulative impact for the National Water Grid will be significant. Collectively, these projects are expected to support over 7,000 hectares of irrigable land and connect 400 new customers. An additional 13,000 customers are expected to benefit from improved water access or reliability.

“Up to 1,175 jobs will be supported during construction, with over 2,550 ongoing and up to 500 more seasonal jobs set to be created nationally.

“The $3.5 billion National Water Grid Fund is paving the way to national water security, while promoting local economic activity and job creation along the way.”

Australian Pipe Friction and Pump Technical Handbooks: vital resources for pump professionals

Pump Industry Australia (PIA) publishes two handbooks which are specifically designed for the Australian pump industry: the Australian Pump Technical Handbook and the Australian Pipe Friction Handbook. These publications are handy reference volumes for those who work and are associated with the pump industry such as manufacturers, distributors, educators, designers, operators and users. Both of the books are easy to follow and can be readily understood with a minimum of technical expertise. It is PIA’s constant aim to ensure that these publications comply with the very latest pumping practice and standards, and as a result both publications have recently been reviewed and updated.

Australian Pipe Friction Handbook

The Australian Pipe Friction Handbook is currently in its fifth edition, having been reviewed and brought into line with the latest Australian Pipe Standards in 2020.

The handbook is split into two sections – the first section covers a series of friction tables which cover the following pipes and tubes, including:

• Commercial steel and stainless pipe

• Large fabricated steel pipe

• Medium and heavy duty galvanised steel pipe

• Uncoated and cement lined ductile iron pipe

• Copper tube

• Brass tube

• Stainless steel tube

• Series 1 and 2 PVC pipe

• Polyethylene pipe

• Rural polyethylene pipe

• Aluminium irrigation tube

• Elastomeric rubber hose

• Concrete pipe

All the above listed tables are based on current Australian pipe and tube standards, except for the commercial steel and stainless steel pipe, a very common pipe used in Australia, which conforms to ASME/ANSI B36:10M-2013 and ASME/ANSI B36:19M-2013

The main changes for this edition are; firstly, the recalculation of the two ductile iron pipe table sets, as the latest standard upgrade involved a change to many internal pipe diameters. Secondly, the addition of an extra page at the start of the commercial steel pipe tables to explain that the tables in this section can be used up to 250mm N.B., for stainless

steel pipe as well as wrought steel pipe.

In addition to the above tables, there are tables for the friction loss of viscous liquids in commercial steel pipe and a chart for the calculation of friction loss in layflat hose.

The second section covers how to calculate the friction loss in a wide range of pipe fittings, valves, etc., together with instructions on how to calculate a pump system total head using the tables in the first section and the fittings in section two. In addition, this section has a range of tables which are useful to the pump engineer.

In summary, the Australian Pipe Friction Handbook covers all you need to know on how to calculate the total head of a pump system.

Australian Pump Technical Handbook

The fifth edition of the Australian Pump Technical Handbook is a widely recognised text that has been produced and designed for the Australian pump industry. The handbook is for those wishing to learn about pumping and to acquire the technical knowledge of pumps and their operation including the overall pump system.

The handbook begins by outlining the units, notations and terms used in pumping, followed by details of the classification of both centrifugal and positive displacement pumps.

The next chapters comprehensively cover the characteristics, selection and application of centrifugal, positive displacement and slurry pumps.

The efficient operation of pump

systems is covered in a chapter detailing where pump and system efficiency losses can occur and how they can be minimised.

The chapter ‘What are pumps made of?’ discusses the metallic and non-metallic materials that pumps are constructed from and provides basic pump material selection data for applications other than water. A table of Australian, European and American material standards is included.

Pipe systems are covered including how to calculate system head which is done in conjunction with the PIA Australian Pipe Friction Handbook

Good intake design is critical to the correct and efficient operation of a pump system and is extensively covered together with how to construct a wide variety of intakes. The common problems to be avoided with intakes – as well as solutions – are discussed.

The pump test chapter covers the standard to which pumps are tested, what data comes from a pump test and the applicable test tolerances.

There are two chapters covering Installation, Commissioning, Operation and Maintenance and Troubleshooting, which discuss what should happen to a pump after site delivery, to the point where the pump is in full operation.

Finally, there are sections covering conversion tables and pumping formulae.

The above illustrates the comprehensive nature of the Australian Pump Technical Handbook, which we recommend to all those with an interest in pumping.

The future of booster set technology

“When we started to think about Esybox Max, we asked ourselves how to manage the evolution of the Esybox range. It was clear from the very beginning, it could not just be something bigger. We felt we had to bring forward the path of evolution, completely changing the rules of the game for booster sets in residential and commercial buildings. Esybox Max is the outcome of listening to and communicating with many different people who will be in direct contact with the product.”

Introducing a new concept and industry-first in the booster set industry, Esybox Max is an integrated pumping system for pressurisation in commercial building services. Available in two power sizes, it consists of modular elements that allow different configurations to cover the needs of medium/large apartment blocks and high buildings (even over 14 floors). Each unit consists of the single, double or triple connection base and the pumping units – a four-pump system is available with the additional kit to connect two double bases.

Large energy savings are achieved with the DAB inverter combined with a brand new permanent magnet motor. DAB also designed completely new hydraulics, making it leaps ahead in terms of energy efficiency. But it is not just energy efficiency that is at the forefront of this new technology.

Esybox Max will improve the storage efficiency in the warehouse. Where there was once one booster occupying space, you can now fit three twin pump booster sets in its place. This allows people to store the full range on one pallet, meaning a customer can pick up an off-the-shelf booster solution of up to four pumps, the same day.

Keeping it flexible, DAB has the on-site assembly concept. So if you have difficulties getting to the pump's location, due to narrow stairways and corridors etc., you can choose to assemble your booster on-site which will only require moving smaller, lighter boxes into the location then carrying out a quick and easy assembly.

DConnect

The Esybox Max also offers full connectivity and control using DAB’s DConnect technology, which is built into the pump and offers many more advantages than typical BMS systems.

Performance, data storage and remote monitoring support users, and facility managers can control their pumps from anywhere, making sure that the running parameters of the pumps follow project specifications exactly and avoiding any possible site issues for complete peace of mind.

HYDROFORMING PROCESS

OWORLD-FIRST TECHNOLOGY

When Ebara Corporation established its factory in Northern Italy, its main purpose was for the production of stamped stainless steel pumps. As well as utilising the most modern manufacturing techniques and equipment of the time, Ebara also developed and patented their own world-leading processes. The most prominent example of this is the hydroformed one piece volute casing.

nce the product and technique was designed by utilising the latest computer programs, it underwent a strenuous testing program. This included the casings undergoing one million cycles of pressure pulsations between six and 12 bar.

The internal deflection due to pipe strain was also measured to ensure the success of the support structure design.

This technology is clearly seen in Ebara’s 3' series of end suction pumps. These have proven their reliability and value for many years now, and continue to be another world-leading product from Ebara.

To complement the success of the Hydroformed Ebara 3LS (all 316 SS) and 3M (304 SS) series of pumps, Ebara Pumps Australia hase recently introduced the low cost 3D series of pumps.

The 3D model uses the same stamped stainless steel components as the 3M but comes with a cast iron casing. This economical close coupled motor pump to EN733 (DIN 24255) dimensions is available in sizes 32mm 1.1kW up to 50mm 11kW at 2900 RPM.

The pumps are an extended motor shaft design and are fitted as standard with high efficiency IE3 motors (three phase versions).

The 3D pump is made at the Ebara factory in Italy and options include high temperature and hard face mechanical seals.

About Ebara Corporation

FLEXIDRAG® – THE PREMIUM DRAG HOSE FOR YOUR BROAD ACREAGE IRRIGATION

When getting ready for spring irrigation, you can’t go past Flexidrag®, the premium irrigation drag hose by Crusader Hose. Its world-class revolutionary manufacturing process gives it all the features and benefits you would expect, while assisting farmers in maximising productivity as well as cost efficiency.

Designed to handle Australian conditions

Crusader Hose has been manufacturing layflat hose for over 35 years, and earned the respect and recognition of being a company dedicated to innovation and continuous improvement. One of the toughest hoses to get right, said Francois Steverlynck, Managing Director of Crusader Hose, is the drag hose.

“One of our greatest challenges to-date has been the manufacturing of a truly high-quality drag hose for Australian conditions. Maintaining a low bend radius, an easy-to-roll compact coil, and non-cracking exterior with the high-level UV exposure, all contribute to the demand on the manufacturing of this hose.”

Flexidrag® is an innovative product designed and manufactured to world’sbest standard, after a heavy investment in R&D and factory upgrades. The polyurethane encased linear move and

Australian-made Flexidrag® irrigation hose, the new force in irrigation, is enjoying its second spring season.

Crusader Hose is dedicated to helping Australian and New Zealand farmers get the most efficient use of their travelling, boom and lateral irrigators with its worldstandard drag hose. The improvements made are keeping farmers, like Jay Drew, happy customers.

travelling irrigator hose can withstand high pressures on water guns as well as remain flexible at low pressures. It has a tight bend radius and can withstand extremely high UV conditions. The popular sizes are ~20 per cent lighter to drag around compared to rubber hose, for extra energy-consumption savings.

Flexidrag® in action

The Gippsland region in Victoria maintains 35 per cent of its farms to dairy cattle, and growing their food relies on efficient and consistent irrigation of the broad acreage fields. For this, no wonder travelling and lateral move irrigators are such a frequent sight across the region.

Jay Drew, a dairy farmer in the Traralgon/Sale area, has been using the original Crusader Hose irrigation hose for many years. When it came time to purchase 220m more for his pneumatic laterals, Jay received the newly designed Flexidrag®.

Delighted with the improvements made with the new Flexidrag® hose, Jay said, “I’m really pleased with its capability to work so well under low pressures as it requires a lot less energy. The bend radius is perfect, never had an issue with kinking. It’s hard wearing. It’s great!”

The working pressures at 2.8 bar translates to the low pumping costs associated with Flexidrag®. Since then, Jay has purchased Flexidrag® shorts to use as special joiners for his 4”, 5” and 6” pump outlets.

A range of options to suit various needs

Crusader Hose manufactures Flexidrag® in a large range of diameters from 40mm to 152mm, and in continuous lengths of up to 350m. This Australian-made hose is suitable for lateral or winch irrigation, effluent pumping, as well as feed hose to pivot, and general farm use. It is ultra-flexible, UV-stabilised and quality tested. The warehouse is well stocked with 3” and 4” hose ready for despatch to assist farmers in getting the stock they need on time, every time.

“For farmers seeking a reliable drag hose for their broad acreage irrigation needs, you can’t go past Flexidrag®”, said Francois, “Australian made here in Victoria, Flexidrag® is of world standard and designed for Australian conditions.”

Flexidrag®

Temporary solution for a wastewater plant

The Dungog Wastewater Treatment Plant (WWTP) in New South Wales’ Hunter Region was commissioned in 1938 – making it over 80 years old – and was acquired by Hunter Water Corporation (Hunter Water) from Dungog Shire Council in 2008. This plant services a township of just over 2,000 residents (just north of Newcastle) and is smack in the middle of dairy and timber country. The existing plant has just completed a $28 million upgrade project to improve water quality, with Polymaster supplying two self-bunded chemical tanks with a dosing system which played a critical role in ensuring wastewater continued to be treated during the build.

The new upgrades will replace the plant's aging infrastructure and provide the town of Dungog and surrounding areas with a modern wastewater treatment plant, allowing for better reuse of effluent and recycled water, and improved water quality for the community. Hunter Water Managing Director, Darren Cleary, said the major upgrade would also help deliver improved environmental outcomes.

Client requirement

The project brief was to build a temporary plant off to the side while the client demolished the old plant and built a modern facility without disrupting the treatment plant.

One critical component was the dosing of sodium hydroxide into the wastewater. The build team required a complete solution they could connect and turn on without building unnecessary infrastructure around it, which ultimately would need to be torn down in the new build.

Solution provided

With any new build, there are complexities that need to be thought through. This particular design team had an added challenge of 'shoe-horning’ a new plant on the same site as the existing plant, which had to remain operational at all times.

Polymaster provided two 30kL selfbunded chemical tanks with a dosing system to help dose sodium hydroxide into the wastewater. A fully integrated dosing system was housed within each cabinet of the 30kL self-bunded tanks. As sodium hydroxide is suitable for Polymaster’s polyethylene tanks, it was a perfect solution.

The designers provided Polymaster with a detailed P&ID for the dosing system to ensure they received a system that ideally suited their application. Polymaster’s self-bunded tanks comply with AS3780 (bund capacity of 110 per cent), so the installation crew did not require the expensive and unnecessary construction of a concrete bund.

Ultimately, the end solution

Polymaster provided is a cost-effective and efficient one – saving time and money. In addition, the installers were able to connect the 'turnkey system' with minimal on-site works, enabling the plant to operate continually. Great job to all involved!

The Dungog plant is now complete, and Polymaster is super pleased to have played a little but crucial part in keeping the operation humming along during the build.

The plant is a showpiece of modern technology and innovative design.

TOP EIGHT WAYS TO IMPROVE

ENERGY EFFICIENCY IN PUMPS

Pumping systems are energy intensive, accounting for nearly 25 per cent of the energy consumed by electric motors, and 20 to 60 per cent of total energy usage in a number of industrial, and water and wastewater treatment facilities. While system changes in pumping requirements, normal wear and tear, and build up in pipes can lead to decreased efficiency over time, specification of the right pump for a particular application that looks beyond the initial cost is commonly overlooked, leading to long-term problems and higher than needed power costs. By pump manufacturers, end users and design engineers working closely together to properly match pump performance and system requirements, pump energy costs can be reduced by an average of 20 per cent in many cases. Here, we look at the top eight things pump users can do to improve energy efficiency.

1. Be wary of oversizing a pump

A pump is generally considered to be oversized when it is not operated within 20 per cent of its Best Efficiency Point (BEP), but if the duty point falls within 50 and 110 per cent of the BEP flow rate, it is usually considered acceptable. This range allows for a margin of error in case the actual resistance curve is overestimated.

There are a number of reasons a pump can be oversized. One reason is that the pump is sized early in the planning and design phase using estimated values for pipework and fitting losses. Due to the need to estimate the equipment requirements, as well as the possibility of the published literature having different reference values for flow resistance coefficient or fittings losses, there is a certain degree of error that can occur when specifying the pump.

Another reason a pump may be oversized is to account for the system design to potentially be expanded in a few years, a correctly sized pump for the current conditions would be unable to meet possible future additional demand. Sometimes a “safety margin” will be added and a larger pump procured and installed to cater for a future expanded system.

There are a few other reasons oversizing may occur, including:

• A pump was urgently needed and the right size was out of stock

• A pump was selected from the spares inventory due to budget constraints

• A new pump was bought to replace an existing pump that was already oversized

• A pump as oversized to account for expected build up of corrosion products on the pipe interior, which

would increase the pump total head requirement

• A “safety factor” may be added to increase pump capacity and head to counter the effects of wear

However, whatever the reason for oversizing, it will have the knock on effect of having higher energy costs due to a higher performance in terms of flow and pressure requiring, more power from the motor, which can lead to unnecessary energy consumption. It is not uncommon to find applications where oversized pumps are being used, as engineers will often specify a pump with a margin of safety in terms of the pump’s duty compared to what the application actually requires. For example, rotodynamic pumps, such as centrifugal pumps, are known to be typically oversized by 20 to 30 per cent. While some oversizing can be good to compensate for uncertainties in the design process as noted previously, a pump that will be operating as close as possible to its BEP will significantly improve its energy efficiency and reduce energy use.

An oversized pump can be identified in a number of ways, including:

• If it needs to be throttled to achieve system requirements

• Has a high bypass flow rate

• Has a flow rate that varies more than ten to 20 per cent from the pump’s BEP flow rate

• If there is excessive flow noise

• If bearings and seals need frequent replacement

• It has intermittent operation, such as pump cycling

2. Trim or replace the impeller If a pump is oversized, rather than replace the entire pump and avoid

costly operating procedures such as throttling to improve energy efficiency, a relatively cost-effective way to reduce the pressure and flow produced is to trim or replace the impeller. Trimming involves machining the impeller to reduce its diameter. However, it should be limited to about 75 per cent of the pump’s maximum impeller diameter, and as the impeller is shaved, the clearances between it and the casing become larger, resulting in greater flow recirculation and reduced pumping efficiency if it is shaved excessively.

By trimming the impeller, its top speed is reduced, which reduces the amount of energy imparted to the pumped fluid, resulting in the pump’s flow rate and pressure to decrease. Therefore, in applications where the current impeller is creating excessive head, a smaller or trimmed impeller can improve efficiency.

Pump casings and shafts are designed to accommodate impellers in a range of sizes, and many pump manufacturers provide pump

performance curves indicating how various models will perform with different impeller diameters or trims. The impeller should not be trimmed any smaller than the minimum diameter shown on the curve.

3. Use a variable speed drive (VSD)

VSDs allow the pump to operate near its BEP at any head or flow by varying the rotational speed of the motor to achieve the actual head and flow demand of the application, rather than what the pump can produce.

One of the main reasons for using a VSD is to improve energy efficiency by reducing unnecessary energy consumption in the scenario where it slows the motor down on a pump that was oversized at the specification stage. The second major reason for using a VSD for increased energy efficiency is where the application requires vastly differing duty demands on the pump at different times.

The amount of energy that can be saved by using a VSD is dependent on

the application and its requirements. In the water and wastewater industry it can often save more than 30 per cent of energy usage; when used with irrigation pumps, power consumption can be reduced by up to 75 per cent; and when fitted to a vacuum pump for use in dairy applications, energy savings of between 40 to 63 per cent can be made. Therefore, while VSDs do come at a cost, as can be seen, in many cases the cost savings they can provide justify the investment.

4. Pumps in parallel

An alternative to using VSDs for a system where there are multiple different duty requirements is to install multiple pumps to provide the flexibility in the flow rates that need to be delivered. Compared to a single pump, installing multiple pumps provides the system with greater operational flexibility, it will have a higher efficiency, the system can continue to function if one pump fails, and there are lower maintenance requirements. One of the

common configurations for this setup is to install a small pump to operate low flow rates and large pumps to cope with the maximum design flow. This ensures none of the pumps need to operate far from their BEP.

However, key to achieving these benefits is correct pump selection as reliability and overall system efficiency can be compromised if the pumps are not properly selected for parallel pumping, or they are not operated in the most optimum combination. This problem is not uncommon and can cause issues such as one of the pumps operating at shut off, resulting in overheating and failure. In order to select the most optimal pump combination, the energy effectiveness (gmp/kW) of each pump should be calculated and then the single pump or pump combination that yields the highest energy effectiveness should be selected.

5. Optimise piping

While piping can be optimised once installed, it can be difficult to fix so it is important to spend time during the design phase of a pumping system to get it right from the start to ensure pressure drops are minimised by avoiding sharp bends and sudden changes in pipe sizes. Low loss valves and fittings should be used and pipe selection should balance the initial cost of the pipe with the cost of pumping fluid through it, for example large pipes might be more expensive, but pumping costs are lower as there are less friction losses.

By optimising the piping, frictional pressure drops will be limited, which in turn will improve energy efficiency as the energy required by the pump to overcome such losses is reduced.

6. Review the motor

Like oversized pumps reduce the energy efficiency of the system, oversized motors can also contribute to this. There are a number of reasons an oversized motor may be specified, including catering for a possible future increase in pumping capacity, where there are load fluctuationsor voltage imbalances, and where the correct sized motor is not available when sourcing equipment.

There are options on the market to avoid oversizing the motor, with some being developed that are able to accommodate short-term overloads and therefore preventing the need to oversize. High efficiency motors can also be installed which provide a range of benefits, including energy cost savings, reduced breakdowns from improved design and construction, and reduced sensitivity of power factor and efficiency to voltage and load fluctuations.

7. Control systems

It is not uncommon for pumps to be operating unnecessarily, resulting in more energy being used than is needed. Installing a control system will enable the pumping systems to be controlled remotely, allowing them to be started and stopped depending on the pumping requirements at the time. For example, where multiple pumps are in operation but only one is required for the current flow rates, the other pump(s) can be stopped and restarted at a later time when a high flow rate is needed.

8. Pump wear and maintenance

Pump wear is a key area where energy efficiency is reduced, with losses ranging from 10-25 per cent. Most wear will occur in the first few years of operation

and will cause a pump’s BEP to move to the left on the pump curve. Signs of wear include cavitation, increased clearance between fixed and moving parts, wear in rings and bearings, and packing adjustment on the pump shaft.

While wear is inevitable, ensuring routine maintenance is undertaken will help reduce the efficiency losses caused by wear, and slow down the wear process. This can result in energy savings between 2-7 per cent. Proper upkeep and maintenance includes replacement of worn impellers, bearing inspection and repair, bearing lubrication replacement, inspection and replacement of packing and mechanical seals, wear ring replacement, and pump/ motor alignment check. When the pump gets to the stage where it’s running too inefficiently and maintenance is not improving it, then replacing the pump is the best option to reduce the long-term energy costs.

As well as maintaining the pump, cleaning and maintaining the pipework will also influence the energy efficiency of the system.

Prioritising changes

This article has looked at eight ways that energy efficiencies can be realised in a pumping system, however, not all points will be suitable or achieve the same amount of energy efficiency for all applications. Any changes need to be prioritised depending on the degree of energy efficiency likely to be realised for a certain application and its individual requirements, as well as the type of pump in operation, e.g. centrifugal pumps typically have the best overall potential for energy savings compared to other pumps.

Efficient priming and Anti-Spit technology: AllightSykes’ recipe to the smart pump

It is widely known that priming a dewatering pump is crucial, both for its ability to meet the intended application and to reduce unplanned maintenance. Failure to do so can result in mechanical seal leakage and significant damage to the pump’s components.

AllightSykes’ compressor priming system allows customers to dry prime their pump without the need to manually fill the suction line or use a wet prime tank.

The compressor prime design employs compressed air which is passed through a Venturi Jet and nozzle that evacuates air from the suction and pump, creating a vacuum and allowing atmospheric pressure to force water into the pump.

This allows the pump to automatically prime and reprime without the need to manually fill the pump with water.

As any pump specialist knows, once the pump has been primed, the nozzle constantly spits out a small amount of the pumped fluid. This discharge from the priming system is usually discharged to the ground and the surrounding environment.

AllightSykes’ new Anti-Spit technology mounts on top of the pump’s priming tee and prevents water discharging out the nozzle once the pump is primed. This allows the pump to be used on environmentally-sensitive applications such as sewage bypass, contaminated water and harsh chemicals without the need to run a hose from the nozzle discharge back to the sump.

The Anti-Spit system not only creates a more efficient pump, but also addresses the market’s need to be more environmentally conscious. With environmental responsibility in mind, AllightSykes’ Anti-Spit technology has come to fruition.

Through innovative design, the Anti-Spit technology can now be retrofitted to any of AllightSykes’ existing products.

ANTI-SPIT TECHNOLOGY

The new anti-spit technology mounts on top of the pump’s priming tee and stops water from discharging out of the nozzle after priming the pump. This means that sewage bypass, contaminated water and harsh chemicals, no longer discharge to the ground and surrounding environment.

Through clever design, AllightSykes antispit technology brings to you a more efficient and environmentally conscious pump. The best part about this new tech? Even your older pumps can be young again - with retrofit being available to all of our existing products!

FLOW PREDICTION TOOL FOR VARIABLE SPEED PUMP STATIONS

Variable Speed Drives (VSD), also known as variable voltage variable frequency drives or pulse width modulation, are commonplace in water pump stations where they allow reliable pressure or flow regulation and substantial energy savings simultaneously. In sewage pump stations, the use of VSDs is less widespread, but through the use of daily cleaning cycles, high torque settings and reverse-run subroutines, the major obstacles to widespread acceptance are being overcome.

By Troy Leyden, Operations Engineer, Fitzroy River Water (a business unit of Rockhampton Regional Council)

Identifying the need to use the reverse-run feature is typically triggered by vibration sensors on the pump, an operator identifying a decrease in pump performance manually by reviewing trends, or a pre-set minimum flow rate being exceeded. Often, these strategies lead to long periods of sub-optimal performance or the inability to utilise the range of speeds and associated energy savings otherwise available.

Developing a flow prediction tool

As part of a recent upgrade of a Sewage Pump Station (SPS) by Fitzroy River Water (FRW), an algorithm was developed as a flow prediction tool. The tool uses the pump speed and well level to predict the expected flow rate of the pump based on the pump characteristic curve, the system curve and the level sensor range. The flow prediction tool is successfully being used to initiate the reverse run feature, and if the reverse-run feature is triggered three times in a 24 hour period the pump goes into an alarm state to alert the operator that maintenance intervention may be required.

The development of the flow prediction tool also had an additional benefit, the pump is controlled such that it changes speed as the well is emptied, keeping the pump operating at or near its Best Efficiency Point (BEP) throughout the cycle. It is anticipated that by operating the pump in this manner it will maximise the life of the pump by minimising vibration. Of course this manner of operation is not possible at all sites, it is dependent on both the system and available pump characteristics. But for this site it was an option, and may influence future pump selection.

Flow prediction in action

The algorithm for predicting flow rate uses pump and system specific characteristics. Then there is a buffer zone to allow for transitional solids that only stay in the pump for a short period. For most sites FRW currently uses ten per cent as the allowance for the actual to fall below the predicted

flow before a reverse run is triggered. This buffer is operator modifiable through the SCADA system, effectively allowing the flow prediction tool to be disabled if required, without the need for personnel to access the site.

To determine the pump and system specific characteristics for the predicted flow to be determined the following process is followed.

Pump full speed characteristic curve expressed as:

= 2 + + W here:

HPump=Pump Head Developed ( m)

System curve expressed as:

Q=Flow Rate ( L/ s) = 2 + W here:

HSystem=System Head at Flow Q ( m)

= ×

R=Level sensor range ( m)

L=Well Level ( %)

HM axStat c = M aximum system static head dur ing the nor mal range of operation ( m)

Unfortunately, some system curves change as they are used due to sections of the force/rising main draining between pump runs. This is unavoidable as the air valves are a necessary part of the network, and it makes the flow prediction tool less accurate. To compensate, a larger buffer zone is used to avoid nuisance triggers.

ENGINEERED INDUSTRIAL PUMPING SOLUTIONS

Expected flow at a given pump speed and well level can be found using:

It may seem that the pump is oversized for the application, but full speed is utilised daily during the well cleaning cycle.

speed relative to nominal speed (

For the recent SPS upgrade by FRW the range of normal operation is to start the pump at 75 per cent speed at 40 per cent well level and increase the speed as the well level falls linearly, such that the pump stop speed is 90 per cent at ten per cent well level. On the following graphs the orange points indicated the predicted flow rate as the speed and well level change.

During rapid inflow such as an extreme wet weather event where the well level rises above the start level of 40 per cent, the pump speed increases linearly to 100 per cent speed by a well level of 60 per cent. However, the receiving network during such an event is expected to become overloaded if the pump were allowed to deliver its entire capacity. So, there is a maximum flow rate programmed into the control system that overrides the speed control based on well level. Should any of the sensors fail the pump’s default speed is 80 per cent of nominal, which is stable for both the receiving network and pump for all well levels, and has no disadvantage in terms of maximum discharge flow rate achievable.

At the maximum allowable flow rate the downward surface velocity of the well is sufficient to effectively clean grit from the floor of the well even during periods of peak dry weather flow.

This algorithm has been in use at one of FRW’s largest SPS since early 2021, and has proven to effectively detect partial blockages early. Moving forward, as the pumps require the impeller clearance adjusted, it will be noticed by the operators by the pump going into an alarm state, thereby avoiding unnecessary energy consumption.

The flanged sleeves are bolted together with high strength corrosion protected fitted bolts and nuts. The sleeve is at the opposite side of the flange executed with an endcap (internal for small and screwed for big size couplings) in which the o-ring is located for sealing purposes. The ESCO gear coupling has been designed to transmit the torque between these two flanges through friction, avoiding fretting corrosion between these faces.

ESCO F series

The teeth of the hub and sleeve are continuously in contact with each other and have been designed with the necessary backlash to accommodate angular, parallel and axial misalignment within their misalignment capacity. The angular and parallel misalignment capacity is determined by the gear tooth design, and is for the standard ESCO gear max. 1.5° degrees (2 x 0.75°) in total. The axial misalignment capacity is limited by the gear teeth length in the sleeve and can be varied (optionally).

Gear couplings are generally made from carbon steel Ck45 (AISI 1040). For higher torque capacities, within the same coupling dimensions, a higher alloy steel like 42CrMo4QT can be used (optionally).

Parallel misalignment can only be accommodated by double engagement type couplings.

The ESCOGEAR F series is robust and reliable. It is ideal for meeting the specific requirements of various rotating equipment machines in all kinds of industries, with torque up to 5,040,000 Nm and bore capacity of 1,130mm.

ESCO Multicrown tooth profile

Lower stresses

The ESCO Multicrown tooth form is a curve with constantly changing radii of curvature. The tooth contact area under misaligned conditions has a much larger radius of curvature than conventional crowning. The contact area therefore is larger thus reducing the surface stresses.

Constant velocity power transmission

ESCO generates the ESCO Multicrown tooth in such a way that the necessary characteristics for homokinetic conjugate tooth action are perfectly achieved.

Less backlash

The ESCO Multicrown tooth design requires less backlash for a given angle of misalignment than the conventional crowning, thus reducing shocks in reversing application.

FLEXIBLE COUPLING SELECTION FOR IMPROVED PUMP AND MOTOR EFFICIENCY AND OPERATION

Despite being an important piece of equipment connecting the pump and the motor, coupling selection is often underestimated, and proper procedure for installation and alignment of the coupling is regularly overlooked. Correct coupling selection is crucial to ensure reliable performance, ease of maintenance and efficient power transmission, while incorrect installation and alignment can lead to premature wear and failure, and damage to the pump and/or motor. Couplings are classed as either rigid or flexible types. Here, we look at types of flexible coupling and applications where they are best suited.

Most flexible couplings consist of two flanges or hubs –that attach to the pump and motor shaft being coupled – and a connecting element that may be metallic (e.g. like in disc couplings), a sleeve constructed from elastomeric material (e.g. EPDM rubber, neoprene, Hytrel or urethane), or mechanical (e.g. u-joint or gear coupling).

The basic function of a coupling is to transmit power, accommodate misalignment and compensate for axial movement, and sometimes it is expected to absorb shock or vibration. There are four basic conditions of shaft misalignment or movement that will help determine the right coupling:

• Parallel misalignment – this occurs when the pump and motor shafts don’t share the same axis of rotation, with their end faces possibly being parallel while the centre axes are laterally displaced

• Angular misalignment – this occurs when the pump and motor shafts are neither coaxial or parallel, with the angle of misalignment possible symmetrical or asymmetrical

• End float – this occur when either or both the pump and motor shafts show axial movement, moving in and out

• Torsional flexibility – this is the torsional movement in place perpendicular to the shaft axis, and is typically caused by shock or vibration

Flexible couplings are designed to handle parallel and angular misalignment, and couplings with four-way flexibility can also accommodate end float and torsional movement.

Classifying flexible couplings

Flexible couplings are commonly classified based on them falling into one or more of the following groups:

• General purpose/special purpose (high performance)

• Lubricated/non-lubricated (dry)

• Mechanical or metallic/elastomeric

• Low speed/high speed

General purpose couplings are generally classified by speed and size, for example a coupling connected to a rotating machine that operates under 100HP is classed as small (sometimes referred to as low); between 100HP and 1,000HP is classed as medium; and over 1,000HP is classed as critical so these couplings are often considered to be special purpose or high performance. Types of couplings that fall into this classification include synthetic gear, pin and bush, jaw/spider and tire (urethane or corded).

Special purpose, or high performance, couplings perform the same functions as general purpose couplings but have been designed for applications with higher speeds and horsepower. Coupling types that can be designed for special purpose are gear, disc or diaphragm, and usually use a spacer between shafts. Gear couplings – which have a mechanical element – usually require constant lubrication, while metallic element types such as disc or diaphragm couplings do not require lubrication.

Elastomeric couplings for general purpose

Elastomeric couplings are limited to general purpose pump applications below 100HP. In these couplings, the elastomer is placed in shear or compression and their ability to compensate for shaft misalignment comes from the flexure and/or displacement of the elastomeric element. They require no lubrication, and consist of two hubs separated and connected by the elastomeric element made from natural rubber, neoprene, nitrile, urethane, Hytrel, or impregnated cloths and fibers.

In shear type couplings, the elastomer can be bonded, clamped or fitted to matching sections of the hubs. These couplings are also known as four-way flexible couplings as the elastomeric element is able to deform or stretch, displacing under a load. They are also able to compress easily and stretch to handle end float.

The level of torsional flexibility that elastomeric couplings in shear have, dampens the amplitude of vibrations, isolating one shaft from the effects of the other, and the energy absorbed during shock loads is used to wind the elastomer in a twisting action. Under excessive shock, they will fail and disconnect the pump from the motor to protect it.

In contrast, compression type couplings usually connect the components with projecting pins, bolts or lugs. They don’t have the same amount of misalignment capacity or axial or torsional dampening capabilities as shear couplings but they do provide dampening to some extent.

There are three basic types of elastomeric coupling: tire, sleeve and jaw. Tire and sleeve types operate in shear to absorb shock and protect the equipment, and torsional flexibility allows them to dampen the amplitude of vibrations, isolating the motor and pump shafts from the effects of each other. The elastomer essentially absorbs the energy generated during shock loads using a twisting action. A major benefit of these types of coupling is that they are designed to fail under excessive shock loads, disconnecting the pump from the motor to protect the pump if a lockup or other condition were to occur. However, depending on the brand and the environment, elastomers in sleeve couplings can degrade when there are excessive changes in temperature and chemical exposure.

Tire couplings are popular for use on continuous-duty ANSI pumps in a variety of applications where there is minimal vibration, as well as applications that require variable flow rates. This coupling type acts as a dampener and handles vibration more consistently than other types. A major advantage of tire coupling is that they can easily be replaced without having to move the pump and motor.

Special purpose couplings for high speed, high torque applications

While elastomeric couplings are good for lower HP applications, they are unable to be used for applications that require transmission of higher torques and speeds. In such

applications, special purpose or high performance couplings that are more torsionally rigid offer advantages. However, these gains do lower their torsional dampening so due to the stiffer design, more vibration will be transmitted to the pump.

Gear couplings are the most commonly used type of coupling in applications above 100HP in both high-speed, high-horsepower and high-torque, low-speed applications as they work well in applications that require torsional rigidity. Misalignment is allowed for by the fit of the teeth, with the degree of angular misalignment compensation dependent on the contour of the teeth and the clearance between them. This allows them to withstand some shock loading, but they are unable to absorb significant amounts.

Grid couplings are also well-suited to high torque operations, allowing for flexibility and efficiency at high speed, or low speed and high torque applications. They can operate up to 400HP, and have the unique ability to reduce vibration by as much as 30 per cent, and cushion shock loads to safeguard driving and driven equipment. However, they have limited ability to accommodate parallel shaft misalignment and don’t transmit as much power as gear couplings. Flexibility is achieved by sliding movement of the grid in the slots of the hubs, and flexure of the grid in the curved slots provides some torsional resilience.

Disc couplings have an extremely uniform design and can rotate at high speeds, making them good for applications with high RPM. They are available in a number of forms, all of which have alternating driving and driven bolts on the same bolt circle, and misalignment is accommodated by the flexibility that comes from the length of material between the bolts. The amount of misalignment that a disc coupling can handle depends on the length of material between the bolts. Torque is channelled by driving bolts pulling driven bolts through the disc material. The more bolts there are, the greater the capacity, but there is a tradeoff with the coupling’s flexibility. They are also extremely sensitive to misalignment and axial movement, and flexing beyond its yield point can cause failure.

SUCCESSFUL PROJECT MANAGEMENT (PART 4)

By Keith Sanders

In previous articles in this series on successful pump project management, Keith Sanders looked at pump system design and equipment selection, and energy audits – the first and second pillars that are needed to aid the success of upcoming projects and contribute to better outcomes for other important objectives such as climate change, water resources and energy conservation. In this article, he takes an in depth look at the third and final pillar: performance testing of pumps.

For projects where pump performance is considered critical, then engineered pumps need to be considered, which allow the engineering requirements to be tightened and hydraulic performance criteria specified to a greater level of accuracy.

While modern design tools allow pump engineers to improve the hydraulic design of impellers or rotating elements and casings etc., the final performance of a pump is determined by physical testing. A typical ITP will include several verification points during manufacture, and these include:

• Drawing approval. GA drawings, assembly drawings and detailed bills of material

• Material testing, traceability and certification

• Witness points for key procedures in the manufacturing process

• Pre-delivery inspection

• Performance testing

So that performance of similar products can be compared, it is usual for pump tests to be performed to a prescribed standard and this is either done at a manufacturer’s works or at a qualified test laboratory with facilities that comply with the requirement of that standard.

Tests are usually performed using water as the pumped medium, particularly for centrifugal pumps, in a closed loop system with suitable instrumentation to take the necessary measurements. Suitably qualified personnel should conduct the tests to ensure the designated procedures are followed and appropriate records are kept.

Performance testing for rotodynamic pumps

Standards Australia has approved a direct adoption of ISO 9906 -2012 as the procedure for testing roto-dynamic pumps. AS/ISO 9906-2018 is currently used in Australia and as a

result, the earlier code AS 2417 -2001 was discontinued and became obsolete.

The major change between these two standards involved a change in the Grades for Testing (from 2 to 3) and the tolerances applicable (from 3 to 6). The new Grades and appropriate tolerance levels on flow, head, power and efficiency are shown below.

Pump test acceptance grades and corresponding tolerances

Grades 1U, 2U are new, as is Grade 1E, while Grade 1B, 2B are retained. Grade 3B is equivalent to AS 2417 Annex A tolerances. Grades 1U, 2U, do not allow for negative tolerances on flow, head or power. 1U and 1E do not allow any negative tolerance on efficiency. It should be remembered that the user can require performance guarantees from the supplier for flow (Q) and head (H) at a particular duty, but power (P) and efficiency (ŋ) are optional and need to be agreed in advance.

It is up to the pump user to decide which grade and tolerance level should be employed for a performance test to suit their purpose and agree this with their pump supplier. In case this is not previously agreed, the standard includes a default level for typical applications/industries where pump performance testing may be common.

It should also be noted that the current test code has been harmonised with the US Code ANSI/HI 14.6, which means that the test procedures in all the major pump producing regions are the same.

Performance testing for rotary PD pumps

There is no Australian Standard for testing rotary positive displacement pumps and most of such products are imported from the US, Europe, Japan or China. As a result, the use of

Note: Tx (where x = Q, H, P, ) stands for the tolerance of the indicated quantity.

either US or European Standards is recommended and these are available by contacting the relevant standards bodies.

• US – ANSI/HI 3.6 – Rotary Pump Tests

• Europe – BS/EN 14343 - Rotary positive displacement pumps. Performance tests for acceptance.

Performance

testing for reciprocating PD pumps

Again, there is no Australian Standard for testing reciprocating positive displacement pumps. There is an American Standard ANSI/HI 6.6 – Reciprocating Pump Tests, which can be used when a performance test is required.

Installation, commissioning and site testing

The importance of this part of the project management cycle cannot be underestimated. Many people assume that the installation of pumping equipment can be done by a collection of qualified tradies who simply follow the installation procedures issued by the respective equipment suppliers. However, experience has shown that a professional Installation & Commissioning Supervisor can play a vital role in the successful completion of the plant installation program.

In earlier times, when Australian pump manufacturers were involved in major project work, they supplied members of their own staff for this critical phase of the program. Such expertise is not so readily available these days, particularly as many companies have been obliged to cut back on staffing levels due to the Coronavirus pandemic. However, Pump Industry Australia has been conducting a regular Installation & Commissioning Training Program and has a register of qualified personnel who can conduct such work.

Again, there are some key points that need to be observed in the positioning, levelling, alignment and pre-startup of the equipment to avoid unnecessary damage by third parties also working in the same pump room. Pipe fitters and sparkies have

Consider GOULDS PUMPS for

been known to undertake their own work without due care and attention to pumping equipment. As a result, coupling alignment is disturbed or pumps are run dry and seal damage occurs in a very short space of time.

Site testing also needs to be conducted in the presence of a pump expert, since the way in which instrumentation is installed can have a significant impact on the accuracy of measurements that are recorded. A team approach is required to ensure that all necessary OH&S procedures are observed.

Summary

By following a well-designed ITP, a Project Manager can keep control of the progress of key pieces of equipment as it passes through the manufacturing program. Generally, close monitoring of the information provided by the supplier at various stages needs to be promptly reviewed and accepted as soon as possible to avoid delays.

Hydraulic performance testing is an important part of the overall ITP to determine that the pump meets its quality and performance expectations. Often, pumps are subject to a String Test, where several other measurements can be taken, such as noise level tests, vibration tests, lubrication analysis, etc. In an overall context it should be understood that the Works Test is the basis on which acceptance of pump performance is established. While a site test may be desirable, this is more valuable in determining the integrity of the whole plant in real time under actual operating conditions. Site tests should also be undertaken by suitably qualified personnel and the results recorded. Judgements about perceived defects in plant performance need to be made and any corrective action considered in conjunction with the pump supplier.

The pump industry relies on expertise from a large and varied range of specialists, from experts in particular pump types to those with an intimate understanding of pump reliability; and from researchers who delve into the particulars of pump curves to experts in pump efficiency. To draw upon the wealth of expert knowledge the Australian pump industry has to offer, Pump Industry has established a panel of experts to answer all your pumping questions.

This edition of Ask an Expert will look at digitalisation and its influence on the pump industry.

Q. How will smart pumps shape the future of the pump industry?

A: Innovations that shape the future and improve lives exist in all branches of industry, also in the progressive cavity pump market. Here, smart pumps will be soon the “game-changer” and standard within many plants. The reasons for that are manifold: tough competition, the strive to increase efficiency and reduce TCO, as well as pumps installed at remote locations require smart pumps. All of them being able to monitor process-critical factors and reduce maintenance times to guarantee plant availability and productivity.

Smart progressive cavity pump monitoring can greatly improve production.

Q. How do manufacturers react to the situation? Which pumps, services and solutions are available?

A: Taken from daily life, progressive cavity pump manufacturers have established online shops as one of their first contact points when it comes to ordering spare parts. In addition, they have developed intelligent products, which complement innovative pump technology with new digital techniques, making the pumps more efficient. Smart Air Injection and Smart Dosing Pumps are good examples for these kinds of products. However, only a few manufacturers are pursuing a more holistic approach. Modular solution networks control and monitor the pumps and optimise processes, maximise availability and reduce inspection and maintenance costs. They range from digitally-supported maintenance via Virtual Reality, to digital pump management with easy spare parts ordering and data-based cloud services.

Smart progressive cavity pump data can be monitored and stored in the cloud.

The so-called Pump Monitor monitors operating data via sensors installed at the pump, thus permanently checking pressure, speed or temperature. All of the generated data can be read in real time on a smartphone, tablet or in the control room. This allows predicting and planning maintenance works. Cloud-based condition monitoring solutions go one step further: continuous condition monitoring, planned and predictive maintenance, remote diagnostics or process optimisation – all this is provided by connected services. Driven by the pandemic and travel restrictions, another trend has emerged. To support customers worldwide with optimal service, AR remote support tools have been established. Customers are guided via app and Augmented Reality through their maintenance work, reducing the need to send experts to the plants, thus increasing a number of prompt service solutions for the customers.

Q. What are the latest developments?

A: Every manufacturer should be setting a focus on digitalisation. Some have started to build their own business units for digitalisation, others focus on continuous product development. One of the most outstanding developments however, seems to be Auto-Adjust concepts. The world’s first

Smart progressive cavity pump with monitoring and Auto-Adjust capability.

self-adjusting pump recently won a German Innovation Award and comes with a re-tensioning device which allows the stator to be adjusted automatically via a hydraulic unit, quite simply from a distance with a click of a button. This newly developed range facilitates work on the pump while maximising energy savings and providing maintenance, shorter, faster, and easier than ever before. Remote locations are just a click away.

Digital pumps will be the norm in a few years. The intelligent 4.0 solutions will make processes more flexible, dynamic and efficient. The improved knowledge about the performance of pumps, the lower maintenance costs and ultimately the high operational reliability are unbeatable arguments that soon nobody will be able to ignore.

Peter Vila, Managing Director of SEEPEX Australia, is a progressive cavity pump expert. He has been involved with pumps for over 40 years. Peter spent the first five years repairing pumps and the following 35 years in technical sales, 20 of which have been with SEEPEX progressive cavity pumps.

PUMP SCHOOL Magnet drive pumps

What is a magnetic drive pump?

A magnetic drive pump is a type of pump driven by the force of magnetism rather than being directly coupled to a motor. Mag-drive pumps eliminate the mechanical shaft seal that conventional pumps require, and they are completely leakproof.

They’re noteworthy for being one of the only types of pump that use the force of magnetism to generate movement. Magnets are mounted on a carrier or drive assembly and are driven by a standard electric motor.

Mag-drive pumps are generally considered a type of centrifugal pump, although there are also some versions of positive displacement magnetic drive pumps (like gear pumps).

What are the benefits of a mag-drive pump?

The elimination of the mechanical seal, one of the largest components of pump maintenance cost, is one of the key advantages of the magnetic drive pump. This greatly reduces the initial cost of the pump as well as day-to-day operational costs as there aren’t any mechanical seals, seal-fluid pots, or cooling lines fitted. The pump is also assured to be leak free.

When would I need one?

Magnetic drive pumps have a variety of applications including pumping chemicals, hydrocarbons, and other liquids that are difficult to seal, or where the consequences of leakage are serious. Also when pumping heat transfer fluids which are high temperature or which are prone to costly evaporative losses with traditional mechanical seals. Mag-drive pumps are also recommended for all types of thin non-viscous liquids.

Key features

The magnets are typically made of ceramic, samarium cobalt, or neodymium. Bushings and thrust surfaces inside the can are made of silicon carbide or tungsten carbide,

or ceramic, to handle the potentially abrasive liquid that circulates inside the can. Most must be protected against loss of flow, which could seriously damage the pump due to temperature buildup due to the magnetic flux.

Selection specifications

The primary specifications to consider when selecting magnetic pumps are flowrate, pump head, pressure, horsepower, power rating, outlet diameter, and operating temperature.

Consult your local pump supplier for choosing the best magnetic drive pump for you.
