Mather & Platt And APE Pumps Leading With New Duplex Pumps COVER STORY

Mather and Platt historically, has been the pioneer of pump technology and manufacturing. Their innovative robust designs of the past continue to influence the basis of many of the pumps they currently have in their product portfolio.

T

hese continue to be adapted to the living conditions today but with the introduction of new materials and compounds that provide a longer lifespan for their pumps even though many of the pumps have been operating for many decades without experiencing any problems.

Many of these pumps have enjoyed additional life after a refurbishment, contributing to exceptional cost savings.

With current, prevailing high energy costs, pump manufacturers and customers alike are looking at reliability, efficiency and performance without a substantial increase in lifetime running costs. The introduction of the Duplex stainless-steel horizontal centrifugal pump ticks all the boxes when it comes to the economies of pump performance and lifetime running costs.

Duplex was developed by Mather & Platt, the duplex pump is manufactured from grades 4A and 4B stainless steel. The name duplex refers to the composition of the material in the construction of the pump which comprises a two-phase microstructure consisting of ferric and austenitic stainlesssteel grains. This translates to a material that is twice as strong as regular stainless steels with better toughness and ductility as ferritic grades, providing a lower coefficient of thermal expansion and higher thermal conductivity. Also, the duplex pump is resistant to chloride stress corrosion, pitting and crevice corrosion as well. Further, duplex stainless-steel has the ability to absorb energy of any dynamic or static nature.

As testimony to the design and construction of the duplex pump, APE Pumps installed a number of duplex pumps at the large abalone farm in Gansbaai in the Cape. The farm has been in operation for the last ten years and was the first abalone farm established in South Africa. Situated in the most southern part of the west coast of southern Africa, it is in close proximity to the sea, subject to cold temperatures and high alkinity sea water. The company, as a result, struggled with pump corrosion which created untold delays in the production process and found that they were replacing pumps every six months. As part of their expansion plans, five LN type split-case super Duplex stainless steel horizontal centrifugal pumps were installed and commissioned. Each pump has the capacity of 1250 m3/ hour to draw seawater under negative suction head from the intake gulley. Since installing these pumps, the company has experienced a greater efficiency in the production process with a corresponding reduction in running costs.

This installation will enable the company to achieve their target of over 30 tons of abalone per annum.

“The super Duplex pump is a very special stainless steel pump capable of performing efficiently in highly corrosive marine environments. We expect to see a growth in sales of this pump especially in the light of the government’s plans to unlock the potential of the South African coastline to create more business opportunities related to the marine industry. With the latest decline in water resources, we see a great potential for the super duplex pump with the possible introduction of desalination plants�, said Dave Johnson, Marketing and Business Development Manager, Mather& Platt & APE Pumps.

The year 2017 sees the celebration of 65 years in existence at APE Pumps. Founded in 1952, the company has been designing, developing, manufacturing and refurbishing pumps for more than half century, harnessing the experiencing the experience and expertise of a close-knit team of engineers, business people and sales specialists to meet the shifting requirements of the premium pump engineering industry. Main product lines include vertical turbine pumps, split casing, end suction and vertical sump pumps, API 610 designs for the petrochemical industry and multi-stage high pressure pumps, all manufactured to the internationally accredited standard of ISO90012000.

Challenges in the Pump Industry

29 years in the Pump Industry.

Quality and lead time problems from foundries in South Africa is a general concern to SAPMA members. The amount of foundries supplying pump manufacturers in SA is declining, so the choice is limited. The poor economic growth of SA and other Southern African countries has resulted in the downsizing of many pump companies in SA over the past 2-3 years. Job losses are also disturbing and have a drastic impact on the economy.

Questions Commonly Asked About “Roots” Pumps.

PUMPS

The Roots type blower is a positive displacement lobe pump, which operates by pumping a air with a pair of “meshing” lobes via a pair of synchronised gears, driven by an electric motor. Either directly or via V-belts.

What is a “Roots” type pump?

The Roots type blower is a positive displacement lobe pump, which operates by pumping a air with a pair of “meshing” lobes via a pair of synchronised gears, driven by an electric motor.

Either directly or via V-belts. Air is trapped in pockets surrounding the lobes and carried from the intake side to the exhaust. Used to pump large volumes of air at pressure levels up to 900 mbar (P) or maximum vacuum levels of -500 mbar (V). There are a few blower designs such as a twin lobe roots blower, tri- lobe roots blower and four lobe “Roots” blowers. However currently the most commonly sold units are the tri-lobe units which offer noise reduction & also a reduction in pulsation.

How long has the “Roots” type pump been around?

The “Roots” type blower are named after the American inventors and brothers Philander and Francis Marion Roots, founders of the Roots Blower Company in the USA. They patented the basic design in 1860 as an air pump for use in blast furnaces and other industrial applications Roots blowers are commonly referred to as air blowers or PD (positive displacement) blowers or Exhausters.

What sizes of “Roots” type blowers / exhausters are available?

Inlet / outlet sizes range from 50 mm up to 500 mm (large units may be available) with flow rates from, in pressure applications, from 100 m3/hr up to 25,000 m3/hr & for vacuum applications with capacities from 100 m3/hr up to 5,000 m3/hr. Vertical & horizontal inlet / outlet flow options are available, (simply change of the feet position).

What materials of construction are available?

Standard units are made from cast iron & ductile steel but units with “wetted parts” in 316 stainless steel are available & one can get special internal coatings as well, depending on the application requirements. One can purchase the units as “bare shaft” units or packaged systems complete with motors, with our without sound reducing cabinets for both indoor & outdoor use.

Typical applications of the “Roots” type blowers / exhausters.

These blowers are widely used for air compressor applications as well as for rough vacuum applications and are typically used for such applications where the volume of air moved is large compared to its pressure. The best part of these blowers is that they are used in applications which require constant air flow rate at varying discharge pressures. Industrial applications like Water/Sewage Treatment Plants, Central Vacuum Cleaning System, Charging of Kilns in Cement and Steel Plants, Blending, Effluent Treatment Plants, Water Treatment Plants, Dewatering, and Air Drying, biogas & pneumatic conveyance of powders or plastic granules or similar product are those industries where the use of these roots blowers is commonly found, just to name a few.

Four Ways To Optimise Pump Performance PUMPS

Pumps are the foot soldiers of the process industry, but their quiet dedication means they are often ignored.

I

gnoring the pumps is a big risk, because when these components break down – or run below optimum efficiency – the whole process suffers. Manufacturing and process companies are under huge cost pressures at the moment, making it vital to maximise assets and maintain uptime. There are ways to optimise their performance in four different ways.

The right bearing Bearings in centrifugal pumps support hydraulic loads imposed on the impeller, the mass of the impeller and shaft, as well as loads due to couplings and drive systems.

They also keep the shaft axial and radial deflections within acceptable limits for the impeller and shaft seal.

The bearings often will face high axial loads, marginal lubrication, and high operating temperatures and vibration, all while the bearings attempt to minimise friction — which, if uncontrolled, can result in power

loss, excessive heat generation, increased noise or wear, and early bearing failure. So, first and foremost, evaluate bearings (types, designs and arrangements) in the context of their anticipated operating environment.

Suitable bearings are available to satisfy even the most difficult conditions faced by centrifugal pumps.

Proper lubrication Improper lubrication accounts for more than 30% of bearing failures. Good lubricants prevent metal-to-metal contact and undesired friction. The common methods for the effective lubrication of pump bearings include: grease, oil bath, oil ring, and oil mist and air-oil.

Oil mist generates the least amount of friction (allowing rotational speed to be based on the bearing design instead of lubrication limitations) and creates a positive pressure within the bearing housing

Baldor-Dodge Raptor Couplings Revolutionise Pumps Industry PUMPS

Couplings are a critical part of many power transmission systems. The Baldor-Dodge Raptor coupling has been designed to replace any existing competitive coupling without any modifications to the existing installation by merely “dropping in” the unit. It meets and exceeds torque, bore and specification ratings of any commonly used coupling.

T

he engineers from Baldor’s Advanced Development Laboratory designed and tested the Raptor coupling to perform under the most extreme conditions. This includes successfully passing the rigorous DIN 740 (Reverse cycle loading), coupling test standard, not once, not twice but ten times for a single coupling.

The Baldor-Dodge Raptor coupling is a product developed by the ABB Group in the USA and to date has received tremendous accolades since its introduction in 2016. The product was officially launched in South Africa at Electra Mining in September 2016 and according to Jacques Conradie, SA & SSA Region Hub Manager – Baldor-MPT & Motors and Generators, “We have received a flood of enquiries since the show and have already received indications of substantial orders from prominent local pump manufacturers.”

Installing the Baldor-Dodge Raptor coupling is quick and easy. The Raptor’s horizontally split element does not require locking during installation, meaning faster installation, requiring fewer tools and also eliminating the possibility of shaft damage.

The Baldor-Dodge Raptor coupling utilises a patented finite, optimised, winged, elastometric element design.

This winglock technology increases surface area in the most critical regions of the element, resulting in higher bond strength, improved fatigue resistance and longer life than competitive options. This feature enables the manufacturer to offer a 5 year warranty on the product.

Hubs are reversible to accommodate a wide range of shaft gaps. Any degree of misalignment up to 4 degrees can be taken up by the Raptor coupling without affecting the performance and subsequently the warranty.

Leveraging over Dodge’s 50 years of natural rubber expertise, the Raptor features a natural rubber flexible element that offers a number of performance benefits when compared to competitive urethane designs.

Major features of the Baldor-Dodge Raptor coupling provide for static conductive elements that allow grounding redundancy, allowing current to safely pass through the natural rubber element, preventing the possibility of arcing during operations. This coupling has exceptional resistance to hydrolysis, improving performance in humid conditions.

The superior thermal conductivity and the ability to dissipate heat and hysteresis build up gives the Raptor

ockwell Automation sub-Saharan Africa was contracted

by Eco Projects, a Rockwell Automation Namibian systems integrator, for equipment to power borehole pumps in Windhoek, Namibia. The borehole development is the first phase of 17-month plan designed to alleviate the critical water supply shortage experienced by the City due to southern Africa’s current drought conditions. Rockwell Automation’s scope of work was to engineer and deliver eight Allen-Bradley PowerFlex 753 low-voltage AC drives varying from 250 kW to 132 kW. The PowerFlex drives are needed to automate the pump systems that transfer water from the boreholes to various reservoirs in the municipal area. “To make sure our drives could safely and adequately power the submersible pumps installed at depths of 150 to 250 metres, we made use of CP Automation, a global member of the Rockwell Automation Partner Network, to engineer the correct sine filters. The VFD and sine wave filter combination allows the motor to run at continuously adjustable speeds and the torque is adaptable to varying mechanical loads,” says Pieter Briel, Industry Account Manager, Rockwell Automation. “Due to the significant cable length from the PowerFlex 753 drives to the motors, it was necessary that sine filters also be installed to reduce the

parasitic capacitances that result from such long cable lengths and result in reactive power.”

The Rockwell Automation order was placed in the latter part of October 2016 and delivery took place during November. Eco Projects was responsible for total electrical installation including construction of switchboards, installation and commissioning.

Six boreholes were commissioned in December 2016.

“Providing the equipment quickly and to spec enabled our systems integrator to successfully implement the project within the three-month designated period. They had excellent support from suppliers, local engineering consulting firms and other supporting contractors,” Briel concludes. “As a result Eco Projects has received the order to install an additional five boreholes, with the commissioning date set for March 2017.”

The additional borehole pumps will be fitted with the same Rockwell architecture, although the variable speed drives will range from 132 kW to 160 kW.

Firstly, the pump’s adjustable suction liner maintains optimal clearances thereby reducing wear and tear and improving efficiency. Then there is the onepiece volute liner that improves the liner wear life from 10 weeks to 30 weeks. An assessment of the pump also revealed that the CURVE pump impeller at 15 weeks had visibly reduced wear compared to the previously installed pump at just 5 weeks.

Pienaar explains how these results prove the CURVE range’s ability to outperform older technology pumps on the market. “When we examine the basic specifications of the previous pump and the CURVE pump in the trial application, they are virtually the same. Both pumps have rubber liners and a 35% chrome impeller. In terms of expected performance, both pumps offer 38 l/s and SG was unchanged at 1.5. The duty covered by both pumps is the Transfer to Plant with a particle size of 80% less than 1.5mm. However, what sets the CURVE S150 apart is that it runs 50% slower in this application. In spite of many similarities on paper, the CURVE S150’s performance is outstanding and proves that our design and engineering is absolutely cutting edge and that we can deliver on the claimed benefits of the CURVE range.”

PAT has been monitoring the performance of the first pumps installed at Hernic Ferrochrome’s OB-Plant on an on-going basis and the results underline the CURVE’s incredible operational performance. “One of the most astounding results we have seen so far is a 73% reduction in downtime. The pump is only opened every third maintenance cycle due to its longer wear life. This was measured in comparison to the wear life and required maintenance of the previously installed pumps,” says Pienaar.

Along with this, maintenance on the pump was reported on as being easier for the client as compared to their experience with previous pumps. This is due to the inherent features of pumps in the CURVE range. For instance: the pump’s encapsulated one-piece volute liner reduces opening and closing time by 80%; eye bolts allow for safe removal of the casing; the casing assembly is a balanced load for safe handling, and the discharge pipe no longer needs to be removed when opening the pump thanks to the newly designed discharge piece.

Pienaar elaborates on the report saying that the pump also reduced electricity consumption due to its efficient design. “An 8% power reduction was reported, through the improved impeller and volute pro¬file design. Slurry follows through the pump in a more natural flow pattern.

A uniform wear design means that the hydraulic profile is maintained and efficiency remains ‘higher for longer’. ” 16

Best Solution “The application at Hernic Ferrochrome is the perfect example of what the CURVE™ range of pumps is able to do for a mine. Now there is concrete evidence that this pump is the best solution for any mine or minerals processing operation. The facts are there to prove that the CURVE slurry pumps save real money,” Pienaar concludes.

Maiden Curve Project During the first three months of 2017, PAT were also awarded their first all CURVE pump project. The project in a new technology flotation application included the supply of 13 of S150 CURVE pumps inclusive of motors and drives. The project was initially proposed late 2016 and the order was finally placed in February 2017 with delivery in March 2017. What makes this project significant is that the wear life of the pumps had to be guaranteed for a fixed period as part of the client’s operation methodology. This obviously made the CURVE an ideal candidate due to its high emphasis on Total Ownership Cost reduction.

Veolia Upgrades Overloaded And Outdated Pump Station In KZN V

PUMPS

eolia Water Technologies South Africa was recently contracted by the Newcastle Municipality to upgrade the Ncandu pump station in KwaZulu-Natal. The existing outdated pump station, situated five kilometres from the town, was unable to meet high sewage capacities, leaving the Municipality and downstream industrial businesses with an overloaded sewerage system.

The existing old pumps were prone to tripping and often flooded the pump station, so the first step of the project saw Veolia cleaning the pumping station, situated 15 metres below ground.

This included removing sump, scraping the walls and rehabilitating the existing infrastructure for the new, larger pumps.

Veolia replaced the aged pumps with two new Sulzer pumps, imported from Germany, that were integrated into the existing pipework infrastructure. Sulzer is one of the Veolia Group’s international strategic suppliers for pumps. The two immersible Sulzer XFP high-capacity sump pumps are capable of processing 220 litres of raw sewage per second at a 27 metre elevation.

“The pumps are set at a standby duty configuration to ensure system reliability. This means that when the first pump reaches 60% capacity, the second pump will automatically switch-on to ensure demand is met and that no flooding or overflow discharge occurs,” comments Blake Cooley, Project Engineer, Veolia Water Technologies, South Africa. “In addition this standby configuration also ensures that if either pump malfunctions or requires servicing, it gives the pumping station a four to eight hour buffer period before breakdown or overflow.” These Sulzer pumps, however, would continue to operate in the unlikely case of overflow due to their submersible designs.

Early in the installation, the existing pumps failed and flooded the entire pumping station. In addition to cleaning the waste, Veolia installed a temporay T8 pump to ensure that no effluent would be discharged during the installation period. “As this was a live operation, we had to bypass the Ncandu pump station using a temporary solution so that the pumping of the sewage to the wastewater plant could continue,” comments Cooley.

To ensure the maintainability of the pump station, Veolia installed a penstock stainless steel gate to effectively isolate the pumps from each other. This means that when one pump requires cleaning or maintenance, the gate will isolate the sewage flow to the functioning pump only. Prior to this, the operators relied on manually handled sand bags, which proved extremely laborious and often ineffective.

In order to power the two 71 kW pumps, Veolia was also contracted to upgrade the transformer and Motor Control Centre (MCC) panels with the help of external instrumentation and control suppliers. “These MCCs provide variable speed and soft-starting pump performance ensuring that their operating capacity matches the sewage demand of the time,” adds Cooley.

These intelligent systems will also immediately alert the operator, via SMS, to any potential pump tripping or overloading. Veolia also installed a precautionary one-kilometre air raid siren to alert the operator of pump station overload or failure.

High capacity! Inside Ncandu Pump Station two Sulzer pumps wait to pump 220 litres of sewage every second.

Safety first: The new pump station features various intelligent systems to alert operators of any malfunction to reduce the chances of pump station failure.

“These safety systems, in addition to our operator training on MCC usage and proper maintenance practices, aim to reduce the chances of any sewage discharge from this pump station in the future,” concludes Cooley.

Veolia repaired and refurbished the existing T6 pumps and returned them to the Newcastle Municipality where they can function in lower-capacity applications. The revamped Ncandu pump station was also designed to accommodate future growth and Veolia completed the required pipework for additional sump pumps as well as made space provisions for a new generator room.

Veolia was contacted for this pump station upgrade in January 2016 and handed the station over to Newcastle Municipality later that year. The company is currently upgrading pump stations across South Africa, with recent completed projects in Gauteng, Eastern Cape and the Free State.

Dewatering: A Vital Part Of Mining?

PUMPS

The answer to this question – of course! As mining works get deeper to provide access to ever diminishing supplies of minerals, mine dewatering is more in demand and the need to provide individual solutions to meet the unique operating characteristics of mines is greater.

S

hort term demand for natural resources is subject to change depending on global economic circumstances but fundamentally, as populations increase and urbanize, they will require greater quantities of mined commodities such as copper, gold and iron ore to meet demand from construction, industry and consumer goods.

Dewatering is one of the vital processes that ensure resources can be mined efficiently and effectively.

The abrasive process of turning rock into valuable commodities means equipment is exposed to significant wear and tear, and therefore even dewatering equipment must be robust for reliable operation. This process is

20

Pumps and Valves Africa - Mar/Apr 2017

supported by another trend: global ore grades are in decline, which means more processing is needed to produce the same amount of raw commodity over time.

Turn Waste into Energy There is a much greater emphasis on the concept of waste to energy throughout the mining cycle, and it is certainly an area that we are concentrating on in dewatering. It is important, particularly where water is in short supply that we continue to develop technology to ensure that the water drawn out by dewatering systems becomes a resource for mining or even for other uses by communities surrounding the mine sites.

Dewatering is a complex and expensive task so it makes a lot of sense to get more value from the water that is drawn out. Rather than it just going to waste – it is increasingly important to manage and reuse the water effectively.

The future and beyond

Dewatering is not just about durability, efficiency and safety, but also helping mine sites to improve the resilience of their processes and activities in the increasingly harsh environment in which many of their businesses operate.

We will continue to invest in fundamental research and development in line with our strategy of growing through innovation and technology development. The focus on fast moving data acquisition, storage and analysis is critical in continuing to improve product operating performance, reduce environmental impact and ultimately lower our customer’s total cost of ownership.

Owing to the experience and expertise of our staff, we are able to customize dewatering solutions to suit the individual requirements of mine sites, wherever they are around the world.

Weir Minerals offers total dewatering solutions for entire operations and has an extensive range of mine and process dewatering products, including a large range of dewatering pumps, hydrocyclones, dewatering screens, valves, specialty hose, tailored pontoons and barges.

WHAT HAPPENS IN VEGAS DOESN’T STAY IN VEGAS Lifting Africa recently attended ConExpo in Las Vegas. The organisers of ConExpo 2017 reported that, over five days, a total of 128 000 people attended the construction equipment show which had a record number of more than 2 800 exhibitors in over 18 627 square meters. The exhibitors represented various segments of the industry such as lifting, pumps, mining, asphalts, aggregates, concrete, earthmoving and utilities. The Gold Lot served as the hub of international crane activity with many of the main manufacturers announcing a good number of sales and potential leads. 20% of these visitors were international, from approximately 150 countries.

The general consensus among manufacturers and customers we spoke to was that the mood at the show was positive, with many reporting a tangible feeling of economic optimism. This is backed up by the organiser’s figures, which show that attendance increased 16% from the 2014 show.

Tina, a Canadian CONEXPO-CON/AGG veteran was only planning to stay at the show until Thursday. However, after three days her mind – and hopefully her travel plan – had changed. “Our flight is booked for tomorrow morning, but we’re trying to switch that. We just love coming out to the show, and Vegas is always a pleasant trip,” she said. Tina has been coming to the show with her husband for over 16 years, and is already making plans to attend the 2020 show.

John, a dealer from New Zealand, found himself caught up in the display. “I just keep standing here looking. It’s all incredibly impressive,” he said as he gazed around in awe at the Grand Lobby.

Exhibitor Chris West from Odisa weighed in on his experience from behind the scenes, and offered some advice to newcomers. “Drink plenty of water and make sure you take a break now and then,” he said. “We’re lucky our exhibit is in the shade, because we have seen a lot of traffic today. It’s really been a great show.”

Show after show, CONEXPO-CON/AGG show management has worked tirelessly to both meet and exceed attendee expectations for the show. With the addition of the Tech Experience and the gold lot expansion, the size of the show is also a major shock to both newbies and return visitors.

Daryl, a CONEXPO-CON/AGG newcomer from Wisconsin was in awe of the setup of the show.“I just can’t believe the size of the equipment here. The amount of planning and execution that goes into this show is truly incredible,” he said. “I can’t even imagine how much time this takes to execute.”

But take it from multiple-time attendee Tina about how best to manage the hundreds of thousands of square feet exhibited at CONEXPO-CON/AGG: “Make sure you have water and a good pair of shoes.”

Cheers To Largest Centrifugal Pump In South Africa T

he largest centrifugal pump available on the South African market for the food and beverage industry has been introduced by Verder Pumps South Africa.

PUMPS

Part its new Packo range of food-grade pumps, the new centrifugal pump is capable of pumping beer into eight million 250 ml bottles an hour. It was launched towards the end of last year.

The Dutch-based Verder Group acquired the UK-based Fullwood Packo Group in 2015, with Verder South Africa embarking on an extensive marketing campaign for the food & beverage industry.

Clive Metz, Packo pump specialist at Verder South Africa, explains that the range has application in 11 niche sectors.

These are dairy, meat and fish, textiles, wastewater and potable water, breweries and distilleries, food and beverage, washing and disinfection, surface treatment, vegetables, animal feeds and biogas, hot frying oil, petrochemicals and pharmaceuticals.

“At the moment, our campaign is focused on breweries and food and beverage,” Metz confirms. Globally, a demand for increased production capacities and more efficient processes in the food and beverage industry has seen a need for stainless steel pumps with flow rates in excess of 1 000 m³/h.

26

Pumps and Valves Africa - Mar/Apr 2017

Responding to this latest market trend, Verder South Africa has launched its Colossus pump, an extension of Packo’s MCP3 and MFP3 pump range. It weighs 1.6 t, and offers a flow rate of 1 200 m³/h, with a 200 kW motor.

While many breweries still use cast-iron pumps for higher flow rates, the stainless-steel design of the Colossus is much more hygienic. “It is likely to become the standard in the food and beverage industry in the future,” Metz comments.

The MCP3 and MFP3 pumps are also energy-efficient and maintained easily, with an electro-polished finish that is highly-corrosion resistant and easy to clean. Applications include dairies, breweries, and distilleries. The pumps are a particularly reliable option for filtration applications, pasteurisation, yeast propagation, and in cleaning systems.

Metz reveals that Packo itself is undergoing an expansion and renovation of its facilities, which will allow it to manufacture and test pumps with a flow rate of up to 2 000 m³/h.

Cost Efficient Grease Solutions For Sugar Mills From Lincoln Lubrication The excellent control and monitoring capabilities of Lincoln Lubrication South Africa’s high pressure Progressive lubrication systems deliver significant savings for South Africa’s sugar mills.

P

rogressive lubrication systems consist of a pump connected to at least one primary metering device.

The pump supplies lubricant which can be oil, fluid grease, grease or compound, to the metering device which splits the lubricant into even or predefined amounts.

Lincoln Lubrication, part of the SKF group, has supplied a number of progressive systems to the local sugar industry for bearing lubrication on sugar mill trains located at the mill front ends. Lincoln Lubrication’s Regional Manager for Kwazulu Natal and Swaziland, Kevin Mills, says that the local sugar industry is facing a number of challenges.

“In addition to the prolonged drought which has affected sugar cane quality and throughput, depressed sugar prices and stiff competition from other producing countries is placing severe pressure on local sugar producers’ revenues and profit margins with debilitating effects on plans for investment in refurbishing or expansion projects.

Consequently capital expenditure over the last few seasons

28

Pumps and Valves Africa - Mar/Apr 2017

has focused on only what is deemed necessary for safe and economical operation.”

Kevin further points out that in an attempt to counter the high cost of lubricant for mill bearings, many mills are experimenting with different types and brands which can affect machinery reliability. “A seemingly inexpensive lubricant can, in the long run, cost the mill dearly in downtime to allow for repairs or replacement of damaged or failed machines.”

Most sugar mills do not have a single brand of lubrication system in use to cover all their lubrication requirements making it difficult to create a standard and maintain spares inventories. “With suitable repairs and maintenance backup for the lubrication systems compromised, the resultant poor standards of lubrication system maintenance and lubricant management can result in contamination of lubricants and lubrication systems leading to premature failures of machinery and components,” notes Kevin.

“We are able to assist the sugar industry in nullifying these challenges with the installation of the High pressure Lincoln ZPU -02 progressive system with Powermaster 4 series 50:1 ratio high volume drum pump with auto filling capability.”

In addition to eliminating lubricant wastage, constant control and monitoring further ensure reliable and correct lubrication supply which, by reducing the risk of mill roll bearings damage or failure optimises plant availability. Kevin adds that data download capabilities are also available from such systems, allowing constant analysis and trending of any system problems as well as indicating exact quantities of lubricants dispensed to the mill bearings.

If low grease levels are detected in the filling station drum, the system sounds the alarm to avoid the ZPU-02 lubrication pump reservoirs from running low. Monitoring of the filling pump functionality ensures that the mill bearings receive grease at all times. The health of the lubrication pump is also monitored; the alarm alerts maintenance in the event that the pump stops functioning so that repairs can be performed immediately with minimum disruption to uptime.

The system also measures the amount of lubricant being consumed by the mill bearings. Proper metered dosages

With fourteen sugar mills in South Africa and three in Swaziland, Kevin says that challenges aside, there is still tremendous growth potential in the sugar industry.

“We have an aggressive growth strategy in place to harness these opportunities with our world-class lubrication technology.”

The Lincoln Quiklube P203 progressive system is ideal for the lubrication of centrifugal machines, sugar dryers, diffusers, cane loaders, cane haulers and excavators at sugar mills while Lincoln grease spray systems are suited to sugar mill drive and pintle gear lubrication. SKF oils circulation systems can be used on turbine-driven cane knives as well as on oil conditioning units for mill train gearboxes.

PUMPS

The progressive system monitors mill bearing grease points for blockages/flow as well as grease levels in the lubrication pump reservoir. Analogue alarm signals are sent via a PLC to the mill control room for pro-active intervention by the maintenance team.

pumped to the mill bearings can reduce the mills’ overall grease consumption by as much as 30%.

Lincoln and SKF Lubrication Systems solutions are available directly from Lincoln Lubrication South Africa as well as through the company’s network of authorised lubrication systems dealers or the SKF network of authorised industrial distributors.

Rexnord Falk Steelflex Grid Couplings PUMPS

BMG’s heavy industrial Rexnord Falk Steelflex couplings are known globally for highly efficient and reliable performance, even in arduous applications.

“

Falk Steelflex couplings have also been proven to minimise downtime – an important factor in determining the total cost of ownership,” says Carlo Beukes, general manager, power transmission, BMG. “Couplings are put under enormous pressure from high impact loads on conveyors, shredders and mixers in harsh operating environments and vibratory loads on high speed applications, like pumps or compressors, can also cause the break down of couplings.”

BMG’s Falk Steelflex grid couplings reduce the impact of high impact loads on equipment by up to 30%. These couplings have a unique “replace in place” design, which eliminates the need to remove or reposition hubs, or re-align shafts, which is required with gear couplings and many elastomer designs. This feature significantly reduces element change out time.

These couplings also offer equipment protection against shaft misalignment. The grid, which is quench and tempered, is free to rock, pivot and float within the hub teeth. This means misalignment capacity is provided, without producing detrimental bearing side loads created by conventional couplings.

When subjected to normal shock or vibratory loads, the grid coupling torsionally deflects. These couplings offer enhanced vibration damping and reduce peak torque by about 30%, also reducing wear on connected equipment components. These couplings act as a shock absorber for rotary motion, relying on the predictable resilience of the steel grid for torsional flexibility.

The Falk grid range, which is available in 25 sizes with various bore, speed and torque capacities. There are 11 models available, including high speed, spacer, flywheel, brake and controlled torque.

These couplings have a maximum bore of 508 mm, a maximum torque capacity of 932 000 Nm and speeds up to 10 000 rpm, depending on the coupling model and size.

This range has a modular design, which reduces the number of spare parts required in inventory. For example, it is possible to convert a close-coupled design coupling to a full spacer by replacing the standard hubs with shaft and spacer hubs. A standard coupling can also be adapted for high speeds by simply changing the horizontal split cover to a vertical split cover. With a few

30

Pumps and Valves Africa - Mar/Apr 2017

additional components, it is possible to adapt the Falk Steelflex inventory to a variety of applications.

Features of Falk grid couplings include a tapered T-grid profile that fits smoothly into the hub to ensure easy installation and maintenance. High strength alloy steel grids are tempered to spring hardness and precision shot peened for increased fatigue strength to protect equipment against shock and vibratory conditions.

Durable, nitrile seals prevent the loss of lubrication and the ingress of water, dust and other materials. Grade 5 cap screws ensure secure fastening of the cover, which can be powder coated for resistance to chemicals.

This range offers high torque-ratings, low operating costs and extended maintenance periods. The application of Falk Long Term Grease (LTG) means lubrication of couplings is not required again for a period of five years.

This grease, which has been developed specifically for couplings, resists the separation of oil and thickening agent that occurs in ‘normal’ greases.

Dewatering is one of the most commonplace activities on mining and construction sites across the world. However, it is also one in which the incorrect selection of pumping equipment could have a major negative impact.

L

ee Vine, managing director of Integrated Pump Rental, cautions that different dewatering applications calls for different solutions, and that it is not always a case of one pump fits all.

customer base, and the company operates an extensive fleet of pumps that caters for all type of application requirements.

As an example, he explains that dewatering on a mine or quarry site requires robust equipment capable of withstanding the harsh operating environment, and more often than not pumps engineered to remove sludge and liquid containing solid particles.

As part of its total round-the-clock pumping solution, Integrated Pump Rental takes complete responsibility for all maintenance of pumps on site. This includes the keeping of a complete maintenance record which facilitates proactive, scheduled maintenance and optimum uptime for the pump installation.

Commenting on incorrect pumping equipment being selected for a given dewatering job, Vine says that this happens primarily because of a lack of understanding of dewatering applications, as well as a lack of knowledge when it comes to pumps and pump design.

Included in the rental fleet are the well-known Grindex submersible drainage and dewatering pumps, the locally engineered and manufactured SlurrySucker dredge units, the SlurryBlaster hydro mining equipment solution and Sykes dewatering pumps.

“Most customers need a trouble-free pumping solution, and this means that the pump must be configured for the specific dewatering application,” Vine says.

Significantly, popularity of the Sykes dewatering pumps has gained rapid traction since introduced into the Integrated Pump Rental fleet just over a year ago. Vine says that it is the ease with which these pumps operate that has driven the market acceptance.

It is imperative that the pumping solutions supplier is able to accurately assess the site dewatering needs, and only then can an optimum dewatering plan be proposed.

Factors such as the required capacity, suction lift and discharge head are important as are the basics such as access to power and logistics in reaching the actual site.

Integrated Pump Rental has built its success on providing fit-for-purpose dewatering solutions to its

“Sykes pumps are simple to use and can handle high volumes of water with ease, but more importantly the pumps are available mounted on skids, site trolleys and road trailers. This makes the deployment of this pumping equipment an easy and rapid task,” Vine says. There are four different ranges available locally.

Pumps in the Sykes Contractors Range are fully automatic priming and can run dry for extended periods of time without damage.

The pumps which have a suction lift up to 9 metres can handle solids up to 90 mm.

The Medium Head Range is engineered to perform reliably in both high water flow and long pipe run applications. These pumps have an efficiency rate of 77% and can handle solids.

The Sykes Himax Range offer what is claimed to be one of the best shaft stiffness ratios on an automatic priming pumps, these pumps handle solids up to 75 mm with ease.

Vine says that although possibly best known in the South African rental market for its diesel driven units, it is important to emphasise that Sykes do not only supply driven diesel dewatering pumps. “The Sykes range can be coupled to electric motors with VFDs so a complete curve or pumping range is available to the customer in a permanent application,” he says.

“What Integrated Pump Rental has proven to date is that coupling our team’s expertise in dewatering with quality pumping solutions we have been able to assist customer with round-the-clock pumping support,” Vine concludes.

Contact:Lee Vine Capable of handling particularly high pressures and loads without compromising its operation, the Sykes Extra Range is designed for efficient and effective dewatering in harsh operating conditions, such as those found in open pits and quarries.

KSB Pumps And Valves Invests In Zambia Global pump manufacturer, KSB Pumps and Valves, has established an independent operation in Zambia to ensure that its rapidly expanding customer base has full access to the company’s world-class sales and support services.

H

aving previously been represented by a network of agencies and dealers throughout the country, the growing number of pumps in the field, as well as burgeoning demand from the agricultural and miningsectors, has prompted the company to invest in more suitable infrastructure within the region.

According to KSB Pumps and Valves regional sales manager, David Jones, the formal establishment of KSB Zambia is aimed at taking the market to an entirely new level with improved stock holdings, shorter lead times for the procurement of pumps, improved price stability and onsite service and support for customers.

Zambian solutions “We rather elected to buy a controlling share in Kitwe-based pump company, Aqua Africa, that is well-established in the copper-belt and is a well-liked company in Zambia.

“Simultaneously we also established a branch in Lusaka that will cater largely for the agricultural market, as well as being well positioned to support water and infrastructural requirements of the residential and industrial markets. Now that the bricks and mortar are in we are planning to double our efforts and reach out to existing and new customers and we think the market is going to like what they see.,” says David.

KSB Zambia managing director, Alf Jacobsen, says when KSB approached him it was an easy decision to make as it was a move in the right direction for his company, as well as for the Zambian pump market. “Right now agriculture is in a strong position and there is a lot of room for us to grow that part of the market.

The new KSB Zambia premises in Kitwe

Pumps and Valves Africa - Mar/Apr 2017

Similarly, mining will always be a strong focus here in the copperbelt and with full access to the entire range of KSB pumps and slurry pumps it bodes well for us to grow this sector in future.

Growing forward “We want to become a one-stop-shop for pump, valves and fluid transfer requirements across all industries and will steadily build a stock holding of pumps and parts that is appropriate for the market. This has the potential to quadruple our footprint world-class products and support locally, as well as from KSB South Africa and the global network of experts.

“From a customer point of view, it will be encouraging to know that they are now dealing directly with one of the world’s major contenders in the pump market and that support and backup will be in line with world standards,” Alf says.

KSB dealer manager for sub-Saharan Africa, Andreas Gremels adds that the move into Zambia is the first in a number of investments that the company plans to make within the subSaharan Africa region. "There is considerable investment going on in Africa in terms of both infrastructure and industry.

KSB South Africa will support this development with further investments into countries in East, Central, West and Southern Africa with a emphasis on countries that already have large KSB pump populations such as Angola, Namibia, Mozambique, Botswana and Tanzania, eventually covering all major countries in Sub-Sahara Africa.

Mine Track And Tools Bouyant In The Mining Industry The mining industry is traditionally a heavy user of slurry, tailings and toxic waste water handling valves because of the abrasive nature of the liquids containing metal concentrates passing through the system.

S

lurry is a material that is primarily a liquid, but contains from small amounts of sand to materials like lime and mud that are very thick and viscous. One of the biggest environmental threats, second only to climate change, is the acid water. The toxic effects of exposure to this type of water (from uranium and other heavy metals), precludes it from being used for animal and human consumption. Mining companies spend millions every year disposing of waste in its various forms and with the help of dedicated long standing equipment suppliers, have curtailed that expenditure as a result of development of new technologies by manufacturers in their respective products. These developments have brought about new design parameters and material applications that have increased the lifespan of the equipment.

Mine Track and Tools, a family business, has been dedicated to the mining industry for the last 30 years. This company can be justifiably proud of its influence in the supply of valves to the industry, being leaders in the Slurry, Water and Air Valve markets. Continuity has been the backbone of the success of the company, with the current management representing the third generation of the Mulder family. The company manufactures its own range of valves, ranging from Knife Gate, Pinch, Butterfly, Air Agitation, Wafer type, and Swing Check valves from its facility in Randfontein.

Flagship of the company products is the WM DIAPHGRAM valve which has proved itself as the outstanding product of its type in the South African mining industry for the past 30 years. As far as slurry valves are concerned, the WM DIAPHGRAM valve boasts the world’s first 25 bar rated range of Diaphragm valves for slurry.

The WM Diaphragm slurry valves are of an advanced design.

The internal contours of the body ensure smooth flow and is suitable for all types of protective lining. The greatest advantage of diaphragm valves is their extreme versatility and this is well developed in the WM type valve. A wide selection of body materials coupled with a variety of highly developed rubbers and synthetics for the diaphragm enable the valve to handle the widest possible range of slurries passing through it. One of the biggest advantages of the valve is that it can be repaired in place without disrupting the installation.

“We are not only a manufacturer and supplier of valves to the mining industry but we offer solutions to clients on special projects and their everyday requirements. This is all part of the personal service upon which we built the company, and is way we have remained one of the leading valve companies in the country. Our partner, Alfred Mthethwa (‘Shorty’), ensures ongoing communication is maintained through various initiatives at the mines like safety presentations, motivational seminars and team building for personnel, on a regular basis,” said Wynand Mulder, Managing Director, Mine Track and Tools.

“Mine Track and Tools, supplies directly to its market without going through distributors or agents. We find this to be very effective in that it enables the directors to be personally involved with the clients on a regular basis, and therefor we are able to be pro-active with our clients, knowing best how to accommodate their specific needs. We are facing new challenges with the changes in the mining industry procurement policies but we have geared our business towards meeting these challenges and so far we see positive results,” added Vincent Mulder, Director.

DPI Plastics Upgrades LargeBore Extrusion Line For New Ultraflo Range PIPES

DPI Plastics has upgraded the tooling on its large-bore extrusion line at its Roodekop facility in Johannesburg in order to extend its current range of Ultraflo™ PVC-m pressure pipes to include diameters of up to 630 mm and a 16-bar maximum operating pressure.

T

he Ultraflo range has been expanded due to a demand in the market for large-bore pipes with higher operating pressures, comments DPI Plastics Technical and Product Manager Renier Snyman. “Our PVC-m pressure pipe range is the only one in Sub-Saharan Africa to include 630 mm diameter pipe up to a 16-bar operating pressure.”

Introduced onto the market in May 2016, DPI Plastics has already secured a major order for the new 630 mm diameter pipe. Applications include gravity and pressure water mains and reticulation, irrigation, and industrial pipeline systems.

Commenting on the constraints facing infrastructure delivery in South Africa, Snyman elaborates: “The challenge is to stay competitive and productive in the current economic climate. We have tendered on a lot of work, and there will be major opportunities going forward when these tenders are finally awarded.”

Ultraflo™ PVC-M, or mPVC, is a tough and resilient, modified PVC pressure pipe, developed to offer greater strength and toughness. Modified Polyvinyl Chloride has been designed specifically to provide similar tensile strength and greater resilience than standard PVC piping products.

It is ideally suited to bulk water supply projects due to it being considerably more ductile than industry-standard unplasticised polyvinyl chloride. The enhanced ductility of PVC-M pipe gives it exceptional resistance to crack propagation under pressure.

In addition to superior toughness, PVC-M has reduced wall thickness. This translates into less raw materials during the manufacturing process, and ultimately a lighter product that is easier to transport and install, thereby minimising its total carbon footprint.

Ultraflo™ pressure pipes from DPI Plastics are manufactured in accordance with the SANS 966 Part 2 specification, incorporating a design stress of 18 MPa. “Our pressure-pipe systems offer design engineers and contractors distinct advantages such as a lower mass,

higher impact resistance and improved ductility, increased hydraulic capacity, and predictable performance,” Snyman concludes.
