COVER STORY

Pompetravaini liquid ring vacuum pumps & low pressure compressors For many years the mining sector have relied on liquid ring vacuum pumps & low pressure compressors for a variety of applications in their processes & even central vacuum supply in the On site laboratories.

o other type of vacuum pump has been able to withstand the heavy duty demands that are placed on this type of pump & without fail they provide years of trouble free, hassle free service within this industrial sector.

How they work The compression is performed by a ring of liquid formed as a result of the relative eccentricity between the pump’s casing & a rotating multi bladed impeller. The eccentricity results in near complete filling then partial emptying of each rotor chamber during every revolution. The filing –and- emptying action creates a piston action within each set of rotor impeller blades/ fins. The pump’s components are positioned in such a manner as to admit gas when the rotor chamber is emptying the liquid, and then to allow the gas to discharge once compression is complete. Sealing areas between the inlet & discharge ports are provided, to close the rotor areas and to separate the inlet & discharge flows.

Other applications. Liquid Ring Vacuum Pumps are used in the refining industry for crude oil vacuum distillation, evaporation, filtering and drying, and in the power industry to evacuate steam surfaces & condensers. Other industries that rely extensively on vacuum pumps are food, chemicals, pharmaceuticals, hospitals& pulp & paper.

Liquid Ring Vacuum Pump Benefits •

Reliable, simple design which involves only one rotating part, which is not subject to much wear. • Can handle condensate vapours or even slugs of liquid entrained in the gas stream without damage to pump or affecting pump performance. • Produces a steady non-pulsating gas flow when it is used as either a vacuum pump or compressor. • Resistant to contaminants entering with gas stream these will be diluted and washed through the pump by the seal liquid. Pompetravaini of Italy have been a market leader in the manufacture & supply of a very comprehensive range of Liquid Ring Vacuum Pumps & Low Pressure Compressors as well as all type of other liquid pumps since 1929.

Men no longer travel to the components but vice versa. This new technologically advanced process has the objective to reduce manufacturing times, shortening delivery times, while reducing error margins to virtually zero. In 2007 Travaini Pompy Polska is founded and the following year, after 54 years of total dedication and intense activity as President, Mario Travaini leaves the chair of the Group to his son Carlo Arturo Travaini (Carlo Jr.) who was for 20 years BOD member, Technical and R&D director. Carlo Travaini has been responsible for the last steps that moved Pompetravaini into a new era boasting state of art automation.

COVER STORY

Pompetravaini S.p.A. was founded in 1929 by the late Carlo Travaini, an experienced machinist with solid production experience acquired while working at the company Franco Tosi of Legnano, Italy.

In the â&#x20AC;&#x2DC;40 the plant moved and doubled in size with adjoining offices.

The current President Ing. Mario Travaini decided in 1968 to rename the company Pompetravaini S.p.A. With technologically advanced production and a sales network adequate for the times, the company began selling products in the European market under its own label.

Once more the company outgrew its facilities and in 1982 a new site of approximately 8000 Sq. Meters was built in the industrial area of Castano Primo, Milan (Italy). The old location was remodelled and utilized for specific projects including the production of specialized pumping systems. Parallel to the internal growth there has been a marketing expansion into international markets. This phase, that was initiated by Mario Travaini in the early years of 1980, made the Pompetravaini brand well known around the world. In 1985 Premier Fluid Systems Canada starts operation followed in 1986 from Travaini Pumps USA. In 1989 Travaini Pompen BeNeLux is founded in the Nederlands and two years after, in 1991, starts Travaini Pumpen GmbH in Germany. In 1999 Pompes Travaini France is founded in France. In 2002 there was another addition to the existing plant. A building of approximately 4000 Sq. Meters was added to house a new computerized stock room and assembly room. This futuristic project utilizes LGV (laser guided

In 2012 Pompetravaini acquires 80% of the Swiss company NSB gas processing AG, based in Basel, now PompetravainiNSB AG. This is a famous company that designs and produces pumps, compressors and engineered skids for the Oil & Gas, Nuclear, pharmaceutical and chemical sectors.

In order to support Pompetravaini-NSB, in 2013 it founded FuturEng. Which is an engineering office specialized in the design and construction of skids with rotating equipment, capable of managing projects up to the final erection and start up. In 2014 BORA Blowers, a well known company specializing in the design and production of lobe Blowers and Boosters, is acquired the Pompetravaini Group. With all the new acquisitions, the international subsidiaries and the very capable distributor and agent network, Pompetravaini is now an international Group that exports to over 80 countries offering solid experience & products of the highest standards. Air & Vacuum Technologies (Pty) Ltd have been the sole agents for the full Travaini range for almost 10 years now & the brand is growing from strength to strength with sales figures / numbers growing year on year.

Growing their Southern African footprint has been a driving force Growing their Southern African footprint has been a driving force for AMD Rotolok that continues to go from strength to strength as it aims to deliver cost effective solutions to industry. Lifting Africa finds out more.

he material handling industry has become extremely competitive, says Theo Sherman, Managing Director at AMD Rotolok. With most companies, still in cost cutting mode and product rates under pressure standing out in this environment is of extreme importance.

“As a global market leader in rotary valves, screw-conveyors, Knifegates, bucket elevators and many other products for both the engineering, food and paper industry, for the powder and bulk handling requirements, we have invested much time and effort in ensuring we are able to meet market demands,” says Sherman. Our experienced and motivated staff will visit clients on site to get a clearer picture of the issues and requirements of the customer. This includes finding out exactly what solutions work under which circumstances. “We also took the time to look at our past best sellers over several years and see where we can make improvements be it on rate or service thus ensuring we were meeting the exact needs of our customers.” According to Sherman it is all about exceeding customers’ expectations. “We have a policy of continued investment in advanced machinery which ensures quality control. We employ batch production techniques to create efficiency savings, which ensures we are able to offer the most competitive of pricing,” he says. “Rotolok also incorporates volume production methods with built-in flexibility, giving customers options and bespoke solutions.” But, says Sherman, complex applications remain the forte of Rotolok and, with a team of experienced system designers, the company has been well placed to provide a solution for any bulk materials handling scheme. According to Sherman there is not a one-size fits all solution. “No,” he says, “it is about providing the best possible solution for a client. We pride ourselves on delivering a total solutions offering.” He says this includes ensuring that they have products in stock across a range allowing the company to offer a competitive maintenance service. “That means not only are we able to deliver the solution that they require but are able to meet their service and repair needs and have the necessary parts on hand to do it as speedily as possible to keep downtime to an absolute minimum.” 14

It is this approach that has allowed Sherman and his team to look at extending their footprint not only in South Africa but across the continent. “There is real opportunity in Africa,” he says despite projects being on hold the past couple of years. “We have a base in South Africa and we can easily service markets as far as Zimbabwe, Nigeria and further north from our local factory. Growing our footprint remains a strategy for the business into 2018. We have become involved in several products on the continent already.” Especially the mining industry is one to keep an eye on. Whilst commodity prices have dropped, Sherman says the industry remains committed to introducing better products. “With the economic downturn came a real focus on cutting costs,” he says. “This saw an uptake in cheaper, imported products. There is a change in this approach as the long-term cost impact is being realized. Not only do these products often not stand the test of time, but the downtime for repairs is often significant.” Sherman says the requirement for good quality products will increase. This bodes well for companies such as AMD Rotolok

“We continue to invest in our craftsmanship,” he says. “Our advantage is not only in being able to deliver that bespoke solution, but we are able to do it quickly and efficiently. The products are also quality.” He says at the same time the solutions being developed are inherent to the African environment. “There is no denying that our product solutions for Africa have to be able to meet the harsh operating environment. That means we have to manufacture robust products that can stand the test of time. As a company, we pride ourselves in being able to deliver just that.”

At the same time, says Sherman, the company have the experience to deliver the necessary expertise that Africa’s particular challenges require.

that have the ability to manufacture on the continent and don’t have to rely on imports.

“We also work closely with our global counterparts,” he says. Other than South Africa, Rotolok has a footprint in the UK, the US, Europe, Singapore, India and Australia. “This really allows for best practice and knowledge sharing on a global platform. As a company, it is about having the real ability to provide bespoke, innovative equipment to match a company’s specific needs,” says Sherman.

PMPS ready to partner shale gas industry ahead of fracking in the Karoo PUMPS

As South Africa seeks to replace its dwindling offshore gas reserves, plans to kick off shale gas exploration in the Karoo basin are at an advanced stage.

head of such a possible mammoth project, PMPS, a packaged metering and pumping solution provider in South Africa, is well positioned to partner an industry where optimal reagent usage is of utmost significance.

The South African government may reportedly award its first licences for shale gas exploration in the Karoo region in the near future. As South Africa seeks to stake a claim in the global shale gas market, exploration will ascertain the size of the reserves, already believed to be among the top five largest globally. As mammoth as it sounds, and despite the possibility of the project creating up to 700 000 new jobs, environmental objections and the requirements for ecological responsibility are still issues to contend with before fracking in the Karoo can become a reality. Having been in the reagent dosing field for more than six years, where it has established itself as a provider of durable equipment, complemented by solid and reliable backup service across some of the most demanding applications, including mining, petrochemical and agriculture, Packaged Metering & Pumping Solutions (PMPS), is more than ready to partner the gas industry. “Our strategy is to be the leader and reliable partner to the gas industry to ensure that reagents used in the fracking process are optimally dosed, installations are secure and spill-free, and above all to provide reliable installations with minimal downtime,” says David O’Neill, Technical Director at PMPS.

Under its ‘Optimum Chemical Usage, these are some of the concerns PMPS will be able to address to help the shale gas industry minimise its environmental burden. “When we say ‘Optimum Chemical Usage’ we mean industry minimum,” explains O’Neill. “This is done by ensuring accurate dosing and continual remote monitoring. Not only does this reduce the environmental impacts, but is also a critical component in the life-cost analysis of chemical injection.” O’Neill argues that it is also a misconception that underutilisation of chemicals in the fracking process is desirable, as it will have less negative impact. “Not so,” he says. “For example, a simple chemical, such as antiscalents, if under-applied or interrupted due to excessive equipment downtime, the pipes would start to scale up, resulting in reduced bore, and the requirement for higher pressures to move the product,” explains O’Neill, adding that ultimately, this means lower efficiencies and higher energy requirements. Once the pipes are scaled to certain levels the requirement for acid washing or similar processes to de-scale the pipes are required, ultimately increasing the chemical effect on the environment. Another cause of downtime is interrupted power supply, especially to the remote regions where this type of equipment is commonly installed. To counter any possible downtime, PMPS offers fully-packaged solar-powered dosing systems, which provide the company with a unique advantage in this industry.

Minimising environmental burden and downtime

Key partnerships

During the fracking process, water, sand and chemicals are injected into the rock at high pressure to allow the gas to flow out to the head of the wall. This is where some of the concerns around fracking emanate, with opponents of hydraulic fracturing arguing that environmental impacts include risks of ground and surface water contamination.

To achieve its stated ‘Optimum Reagent Usage’ strategy, PMPS has entered into some strategic partnerships with some of the leading players in the industry. “We have signed an exclusive agency agreement with Solar Injection Australia (SiA), a leading manufacturer of high pressure dosing pumps specific to the industry,” says O’Neill.

Pipes, Pumps and Valves Africa - Nov/Dec 2017

the case with unconventional production. In many instances, well-heads are located on third-party private land and therefore site visits become a key negotiating point. There are a number of ways to influence maintenance intervals, including selecting the correct gear-motors for the application; the use of life-time lubrication in the gearboxes; selecting the correct seal material for the chemical being injected; using 316 stainless steel in all wetted areas leak detection devices; and the ability to communicate remotely with equipment in the field. Choosing a chemical injection pump that can deliver on these makes good economic sense.

Optimal Control:

PUMPS

Flow meters provide a closed-loop control, ensuring injection exactly matches the amount of chemical set and therefore are the most accurate way to control dosing. Ensuring the chemical injection pump can cycle at relatively slow speeds of around 60 cycles per minute.

Quality: SiA Pumps combine quality manufacture with unique design features such as Dual-Seal technology, which reduces leaks and prolongs seal life to maximise reliability in the field and push out service intervals. The use of a reciprocating single acting positive displacement chemical liquid ends with 1” of stroke provides more accurate dosing control, as does the in-built stroke adjustor, exclusive to SiA pumps, which allows turn down of between 0-100% of displacement. Remote monitoring and control is also available, with standard systems able to be upgraded easily over time as more sophisticated control is required. “The whole requirement regarding quality is sometimes more demanding than the actual installation of a dosing pump,” notes O’Neill.

Support matters

SiA’s range of products is a great complement to PMPS’s existing, industry-known brands, namely: OBL Metering pumps (API675), Novarotors Progressive cavity pumps and Greenpumps’ magnetically coupled centrifugal pumps. Meanwhile, PMPS’s partnership with SiA enables the company to apply its strategy moving forward, according to O’Neill. The SiA injection pumps provide:

Low downtime due to correct selection and minimal maintenance: Maintenance intervals are especially important during production when faced with many wells spread over large gas fields, as is often

Apart from just offering equipment, PMPS is currently in the process of setting up a satellite office to provide customer support and ongoing maintenance, specifically in the Karoo region. Meanwhile, O’Neill notes that supplying equipment to the petrochemicals market is particularly demanding, as all equipment and installations for this market need to adhere to the specific taxing documentation requirements. “This includes material certification for components, pressure test certificates, as well as witness testing, among others. PMPS currently employs 13 people – six of whom are dedicated to manufacturing, installation and service – and provide ongoing maintenance on a national scale,” concludes O’Neill.

Cairn Indiaâ&#x20AC;&#x2122;s Rageshwari Gas Terminal treats gas from other Cairn sites and is the only plant in Rajasthan that solely processes gas. The natural gas contains impurities, which are removed in primary and secondary clari ers, and moisture, which is removed by processing with glycol injection. The glycols are introduced at high pressure to overcome the natural gas pressure. An accurate controllable, low pulsing ow is essential as too much glycol will absorb more methane which cannot be reintroduced into the gas stream and too little will not dry the gas adequately. Hydra-Cell P200 metering pump was selected in preference to a locally manufactured single diaphragm pump because it gives a virtually pulseless ow and is more ef cient, consuming only 0.35kW per hour. The recirculating glycol can also contain impurities and particles which, of course, pose no problem for Hydra-cell pumps.

Hydra-Cell G35 high pressure, diaphragm pump Conventionally the G35 has been rated with a maximum pressure of 83 bar and a maximum flow rate of 140 litres per minute. The new version, is now rated with a maximum pressure of 100 bar at a maximum flow of 67 lpm, which should open up new applications for this popular and economical Hydra-Cell model. The pump is available with a wide variety of liquid head materials, including brass, cast iron, duplex 2205, super duplex 2207, nickel alloy (Hastelloy) and 316L stainless and variety of flange types is available on request.

Lack of dynamic seals Capable of pumping both hot and cold liquids, in a wide range of viscosities, Hydra-Cell pumps are characterized by their complete lack of dynamic seals, 18

Pipes, Pumps and Valves Africa - Nov/Dec 2017

making them ideal for transfer pumping, dosing, injection and metering applications where complete liquid containment is essential. Having no dynamic seals also enables Hydra-Cell to pump abrasives and dirty fluids that may contain abrasive particles, situations that would eventually cause problems for other pumping technologies. The multi-diaphragm design produces a low pulsation flow designed for a range of dosing applications. Controlling pump flow and pressure is not complicated as output of the Hydra-Cell pump is directly proportionate to its speed, and virtually independent of system pressure. So a relatively simple system using VFD to vary motor speed gives accurate flow control with fast response.

typical single-stage pump includes a throttle bushing that is located below the sealing mechanism.

The throttle bush supports the shaft as well as being a close clearance bush and creating a stuffing box cavity with increased pressure differential reducing flush water requirements. “Where you have a slurry or fluid particles, it is important to keep this away from the seal,” says Daniel Hechter, Head of Servicing at FITT Resources. “We recommend Vesconite throttle bushings, and have found that pumps perform as expected and that seal life is extended with reduction in flush water requirement” he says, noting that, as the sup-plier for various OEM seal brands and pump repairer, client companies trust this recommendation, and use the bushings as part of a good proven pump repair package.

Peristaltic pumps rectifies the pH balance of acid mine water Rectifying the pH balance of mine water After decades of uncontrolled industrial (mining) activities, water supply is under serious threat. Studies show that acid water levels in the country's mines are rising at a staggering average rate of 0.59 m/day. The water situation is in fact threatening the population’s survival. At the heart of resolving this problem are the treatment of water and wastewater. This article looks at peristaltic dosing pumps used as part of the process to rectify the pH balance of acid mine water. It highlights a successful implementation at a uranium wastewater treatment plant, focusing on but not limited to: the cost of ownership; plant performance (plant availability and reliability); and dosing accuracy. The impact of acid mine drainage (AMD) is devastating, with far-reaching and long-term eﬀects on the environment. According to recent research, AMD could not only aﬀect South Africa’s quality of water, but also poison food crops, destroy heritage sites and lead to a decline in agricultural production with related job losses, to name but a few.

Peristaltic pumps for dosing lime: According to the experts consulted by the Department of Water Affairs, the most suitable process to consider in dealing with the current AMD issues is the ABC (alkali–barium–calcium) process, developed by South Africa’s Council for Scientific and Industrial Research (CSIR), which consists of the following steps: 1. Lime and/or CaS pre-treatment 2. Barium treatment for sulphate removal 3. Sludge processing. This is the most comprehensive treatment that will ensure that the treated water is fit to be introduced back into nature but is not necessarily suitable for human consumption.

compression and relaxation of the hose, drawing content in and propelling product away from the pump, in the same way that food is pumped through the body. This process makes a peristaltic pump an accurate dosing or metering pump, with an equal amount of liquid dosed each time. Correcting the pH is a very specific process and the pump used for dosing must be very accurate. Peristaltic pumps have a linear flow-speed characteristic and excellent repeatability, making them the most accurate solution available. The liquid being pumped never comes into contact with any moving parts because it is totally contained within the reinforced hose. A rotating shoe passes along the length of the hose creating a total seal between the suction and discharge sides of the pump. As the pump’s rotor turns, this sealing pressure moves along the hose, forcing product to move away from the pump and into the discharge line. Where the pressure has been released the hose recovers, creating a vacuum, which draws the product into the suction side of the pump, the priming mechanism. Combining these suction and discharge actions results in a self-priming positive displacement pump, the peristaltic pump. The perfect seal between the two sides of the pump means that there is no product slip; when coupled with the pump’s linear speed-ﬂow characteristic it makes peristaltic pumps ideal for dosing. Additionally, as the pumped liquid is totally contained within the hose, this makes a peristaltic pump an environmentally safe pumping solution with zero chance for contamination. This also reduces maintenance time as the hose is the only wearing part.

The nature of the medium being pumped is an important factor when considering pump selection for a speciﬁc application. When pumping lime, the high viscosity of the medium often causes pumps to clog up, resulting in a maintenance nightmare.

The pulsation eﬀect means that solids are kept in suspension. Build-up in the hoses is eliminated by using rubber hoses that are designed to maximize life expectancy and performance. Hose pumps are designed to handle these tough operating conditions, ensuring optimal process ﬂow.

Peristaltic pumps are a type of positive displacement pump used to convey a variety of fluids. The fluid is contained within a flexible hose fitted inside the pump casing. The actual pumping principle, called peristalsis, is based on alternating

Famed SA attraction benefits from SewTreat’s sustainable sanitation technology The environmental footprint of world renowned tourist attraction, the Bourke’s Luck Potholes in Mpumalanga, has been taken to new level thanks to SewTreat’s supply of a biological waste water treatment plant for the Mpumalanga Tourism & Parks Agency.

he existing septic tank system servicing the main reception and bathroom facilities at Bourke’s Luck Potholes has been replaced with sustainable sanitation technology thanks to SewTreat. “This technology will ensure that from now on, only clean, recycled effluent is discharged into the Blyde River thereby helping to conserve and preserve the precious ecosystem if the Blyde River system,” enthused Theunis Coetzer, spokesperson for SewTreat. The Bourke's Luck Potholes welcomes in excess of 1 million visitors annually – the majority of which are foreign tourists. According to Coetzer, the existing infrastructure was out-dated could not cope with the high volumes of effluent produced. “The old septic system was discharging substandard effluent into the Blyde River causing secondary contamination and pollution of this pristine river system,” said Coetzer. Through the appointed consulting engineers for the project, SewTreat was contracted by the Mpumalanga Tourism and Parks Agency to design, construct and install a complete waste water treatment plant for all effluent generated by the current sanitation facilities at the Bourke's Luck Potholes site. The decision to appoint SewTreat was based on the ability of their products to treat waste water and sewage using environmentally friendly methods. “Our motto is to treat nature with nature,” Coetzer explained. “All our plants make use of our proprietary strain of natural bacteria developed by our in-house team. The bacteria ensure that all waste is treated by a biological process resulting in a clean final effluent that is kinder to the environment.”

Biological wastewater treatment is an accepted practice used worldwide. The process involves confining naturally occurring bacteria at a very high concentration in the treatment process, whether it in plastic type, containerised type or civil constructed type treatment plants. From here this bacteria, together with some protozoa and other microbes (collectively referred to as activated sludge), are treated in an anaerobic and an aerobic process. They are then returned to the anaerobic phase to eliminate sludge accumulation and waste generation. Coetzer elaborated by saying: “In a nutshell, the bacteria digest all impurities and the wastewater is then cleansed. The treated wastewater or effluent can then be safely discharged to receiving waters – normally a river or the sea – or alternatively used for irrigation, flushing of toilets or general non-potable uses.” 22

Pipes, Pumps and Valves Africa - Nov/Dec 2017

After conducting a full assessment, SewTreat opted to supply a plastic, above ground type waste water treatment plant which would cope with the amount of waste to be processed daily, could be installed easily given the challenging access to the site and would be completed under a tight deadline and budget. SewTreat’s technology will now ensure that the Bourke's Luck Potholes and the Blyde river system are kept pristine and unpolluted at a staggering rate of 7.5 million litres per year. Coetzer concluded by saying: “We hope that by offering wastewater management products that are cost effective, easy to install, simple to maintain and provide a green waste solution; we can help all of our precious local tourism and conservation sites move towards a greener future. Preventing further damage to the environment requires a fundamental shift in how tourism operations conduct their business and manage resources. Changing how you treat your wastewater to a method that results in reusable effluent is a major step towards sustainability where the long term beneficiaries will be South Africa’s nature, wildlife and resources.” Contact SewTreat, www.sewtreat.co.za

SA HIPPO flameproof submersible pumps exported had a 98% local content The HIPPO Flameproof Submersible Slurry Pump Range which has been designed, developed and manufactured in South Africa has a minimum of 98% local content â&#x20AC;&#x201C; with only the bearings and mechanical seals being imported.

ll manufactured components for the HIPPO Pump Range have a 100% local content while all castings manufactured in South Africa and all the machining of the components is done in-house at the HAZLETON PUMPS manufacturing facility in Centurion.

The international market, and in particular Canada, has been the main source of clients requiring specialized pumping systems and in most cases, large volumes of acidic liquids containing solids are required to be pumped. This has led to the design, development and manufacture of exceptional large slurry submersible pumps which in most cases are the first of its kind in the world. The development of large slurry submersible pumps to suite the international market requirements - to pump high volumes of acidic liquids containing solids at high heads necessitated the establishment of a manufacturing facility in South Africa. To cater for the development of these new technologies HAZLETON PUMPS had to ensure that these large pumps would be manufactured economically to compete in the international market - the largest pump that has been produced weighed over 10 ton with the largest component weighing over 2.5 ton. The first challenge was to find a reliable foundry capable of producing the required casting from Duplex Stainless and in particular Sanicro 28. The second challenge was to have these castings accurately machined to ensure interchangeability when replacement parts are required for maintenance. With regards to the castings numerous foundries were found to be capable to produce large Duplex Stainless Steel castings, but no company in South Africa was found that was able to do the machining economically. Therefore, the only viable alternative for HAZLETON PUMPS was to set-up a machining facility to manufacture the pump components.

The first HIPPO High-Volume; Medium Voltage Slurry Submersible Pump produced at HAZLETON PUMPS manufacturing facility.

With limited funds the plan of action was to go to auctions where machines from large engineering firms that have closed down were for sale and with the down turn in the economy HAZLETON PUMPS was able to procure the required machines at affordable prices. The next challenge to face was to adapt these machines to be able to manufacture pump components to the required standards. In order to ensure interchangeability of pump parts specialised machining jigs and fixtures were also developed. Once the machining capabilities were successfully achieved the next step was the training of machine operators, since 24

the products are highly specialised and have to adhere to very stringent standards i.e. being flameproof and that the machine operators had to be re-trained to adhere to these exact standards. Preference was given the recruitment of suitable, previously unemployed people from the nearby community to be trained as operators.

PUMPS

The techniques of machining of Duplex Stainless Steel also differ from the machining of standard materials. The main problem encountered is that this material â&#x20AC;&#x153;work-hardensâ&#x20AC;? with every machining cut and therefore the casting has to be very close to the machining size so as to have the minimum amount of machining cuts during the machining process. For more than 20 years HAZLETON PUMPS has been continuously awarded for the management of technology and use of innovation and in 2017 received the SASSDA Award for Manufacturing Excellence, as well as main two SEIFSA awards for both Product Innovation and Customer Service. Although HAZLETON PUMPS has standard pumps in the HIPPO Slurry Pump range, the company specializes in designing pump systems to satisfy the specialised requirements of customers and in most cases specific pumps are designed to ensure the optimum results in the design of a pump system.

These pumps are particularly suitable for transporting media with some minimal lubricity, is chemically compatible and does not contain solids,” says Joe Pinheiro, BMG’s national product manager, pumps. “SF gear pumps are used as circulation pumps in oil lube systems, kidney systems and for transferring (off-loading or dispensing) of oils. “These compact pumps are easy to assemble and detach. The standard design is supplied with a clockwise rotation, which is easily altered to anticlockwise, by rotating the end cover plate by 180˚. The direction of delivery flow will change at the same time. An optional feature is an adjustable pressure relief valve built in the housing, for short-term protection against pressure spikes. Optimum integration, with minimal tolerances of the pinions and gear wheels results in quiet, smooth running. The use of gear wheels with 12 teeth reduces delivery flow pulsation and minimises noise during operation. Shaft journals are mounted in composite bearing bushes, which ensures continuous duty and extended service life. All pumps sizes can be equipped with an anti-friction bearing at the driving end, to accommodate radial and axial forces. Standard pumps have a maximum rotational speed of 1800 rpm for a maximum viscosity up to 380 cst and a differential pressure up to 25 bar. The maximum permissible rotational speed depends on the viscosity or lubricity of the medium. The higher the oil viscosity, the lower the speed. These pumps can 26

Hytec Engineers ‘Fluid Power Fitter’ qualification PUMPS

The Hytec Group has become South Africa’s first company to receive full accreditation as a training provider to qualify ‘Fluid Power Fitters’.

he Hytec Group, a hydraulics, pneumatics and automation specialist company, received full accreditation with program approval from the industry sector education and training authority – merSETA – to provide theoretical and practical training for the National Certificate Mechanical Engineering: Fitting (Fluid Power); and the National Certificate Mechanical Engineering: Fitting (Manufacturing, Engineering and Related Industries), both at NQF level II. Registered with SAQA – the South African Qualifications Authority – the two qualifications comprise 49 individual unit standards (short courses) each with theoretical and practical components clustered into a learnership, which has a one year duration per NQF level. As the unit standards are dedicated to specific learning areas, learners may opt to qualify by following the full learnership route or undergo training for selected unit standards only. “This provides the flexibility for learners to complete the qualification in a unit standards format over a longer period if they are unable to complete a continuous learning programme,” says Allen van Gent, Hytec Group Training Manager and the driver behind the successful reinstatement of the fluid power qualification, the company’s accreditation and the programme approval. There are currently four learners undergoing training at Hytec for the National Certificate: Mechanical Engineering: Fitting (Fluid Power) who, once qualified, will be the first Certified ‘Fluid Power Fitters’ in South Africa trained by a South African training provider. This is an achievement that the South African fluid power industry has been striving to achieve since 2009 when the qualification was originally registered with SAQA,” van Gent asserts. According to the SAQA qualification documentation, this qualification is comparable with many other countries, such as New Zealand, Australia, the United Kingdom, Zambia, Zimbabwe, Kenya, Tanzania and the United States, to name a few. The National Certificate Mechanical Engineering Level 2 is the first in a learning path of three consecutive qualifications which culminate in a Further Education and Training Certificate: Mechanical engineering, NQF Level 4, within the context of a traditional designated trade specialisation. The importance of the certification cannot be underestimated, according to van Gent who admits to there being numerous mechanical fitters with hydraulics industry experience. “It is the formal recognition of the specific training that’s important,” he points out. Essentially, the scope of training that we are accredited to provide encompasses every aspect that a ‘fluid power fitter’ needs to know in order to conduct his dayto-day activities within the fluid power industry. It is believed

that qualified ‘fluid power fitters’ will save their respective companies, or clients, hours in downtime and reduce their spare parts expenditure.” Currently Hytec’s training facilities provide for theoretical and practical learning of 36 learners. However, once housed in the new Hytec facility, due to open in 2018, three dedicated training rooms will be able to accommodate a combined capacity of 120 people. “One of the great training advantages of our new premises is the proximity of the theoretical training venues and the practical on-site location being in the same building,” van Gent says. “This means that learners are exposed to all facets of the qualification within the fluid power industry under one roof.” Another part of the learning experience will be a stateof-the-art WS290 hydraulic and pneumatic training workstation donated by Bosch Rexroth Germany. The hydraulic power unit, with a loud sensing double pump, can accommodate four to six trainees simultaneously. It is perfectly suited for training sessions with respect to on/ off, electro, proportional and closed-loop control hydraulics topics and on/off, electro pneumatics and PLCs which incorporate modular mechatronics systems. “This provides the type of training that is required to deem competency with respect to the qualification,” van Gent says. “We’ll use this state-of-the-art training workstation in our theoretical training and practical simulation to ensure that all learners

gain hands-on experience in a controlled, practical learning environment.” The full accreditation and programme approval process was a long and arduous one, beginning in 2016 as far as Hytec’s involvement is concerned, which was to maintain the existence of the qualification. However, the process has a history dating as far back as 2006. It was in this year that the South African Fluid Power Association (SAFPA) began designing and developing a curriculum for a National Certificate Mechanical Engineering: Fluid Power, a process which took them three years to finalise. There was no associated specification as a ‘Fluid Power Fitter’ or Technician in the legacy qualification prior to 2006. “During the qualification design phase, SAFPA registered the curriculum and associated learning material with SAQA,” van Gent explains. “Unfortunately, post 2009 no learners were registered against the qualification and, because of this, SAQA deregistered it in 2015.” merSETA then replaced the qualification with the Quality Council for Trades & Occupations (QTCO) Tool Maker Occupational Qualification. Subsequently, SAFPA attempted to reinstate the original qualification as it planned to introduce a pilot programme for the fluid power industry. The pilot programme did not gain approval as the entire qualification had already been deregistered. “SAQA required proof that industry faced a shortage of ‘fluid power fitters’ and that there would be definitive interest and uptake in the qualification,” van Gent states. During the course of 2016, SAFPA enrolled six learners onto the NQF level II pilot programme administered by TVET College JFa² Technical Training Institute, an East Rand-based TVET college. The college focused on the theoretically driven Core and Fundamental Unit Standards. JFa² Technical Training Institute was endorsed by SAFPA in 2016 to provide the theoretical components of the qualification. “However,” van Gent asserts, “a company accredited to provide practical training was needed and at this stage as there was no

hydraulics company accredited to do so.” It was at about this time that Hytec, concerned over the existing training gap for ‘Fluid Power Fitters’, for which there is a legitimate industry need, got involved. Thus began the long and convoluted interactions between the relevant stakeholders, all doing their best to get the NQF qualification reinstated as it was prior to it being linked to the QTCO qualification. “Our goal was two-fold,” points out van Gent. “We needed the qualification reinstated and we aimed to get Hytec fully accredited as a training provider with programme approval for the full qualification”. Hytec and JFa² worked closely with the merSETA to get the qualification reinstated. Once SAQA approval had finally been obtained, Hytec employed and registered the learners who had completed theoretical training and wanted to continue with the qualification. Of the original six learners, only four remain. After many negotiations and a lot of work carried out by Hytec Group’s Training Department, Hytec received full accreditation as a training provider with programme approval. “We were subsequently informed that, as of 2019, all Legacy SAQA qualifications will be realigned or replaced by a QCTO occupational qualification,” van Gent says. “Subsequent to receiving this notification, relevant stakeholders in the fluid power industry are in the process of applying to register a QCTO Qualification: Fluid Power Fitter, and both SAFPA and industry will be kept up-to-date regarding the progress as it unfolds.” At the time of writing, Hytec was awaiting feedback from its submission for registration with the Department of Higher Education.

Bosch Munitech’s irrigation system construction services for emerging farmers Bosch Munitech, part of Bosch Holdings, has extended its construction services to now incorporate irrigation systems and other water related solutions, including borehole drilling and the installation of borehole pumps.

“

The company plays an important role in the development of agriculture in South Africa by working closely with the Government to support emerging and community farmers,” says Conrad Adendorff, mechanical specialist, Bosch Munitech. “One of our flagship projects was the Clanso Irrigation Scheme, near Empangeni on KwaZulu Natal’s north coast. The Munitech team worked closely with the Department of Rural Development and Land Reform and emerging farmers in the area to install a system for the irrigation of sugar cane and vegetables. This project comprised the construction of a river abstraction point, booster pump station, bulk reticulations, 2 Ml lined steel reservoir and a drag line irrigation system.

center pivot irrigation system for the Moutse irrigation project in Groblersdal. Advantages of utilising centre pivots as a means of irrigation include a lower inlet pressure and therefore reduced pumping costs; low maintenance requirements and easy system management. Modern sprinkler packages ensure minimal evaporation and excellent uniformity of water application.

“Two other recently completed projects for emerging farmers involved the construction of small to medium sized systems, to provide irrigation for maize, vegetables and grazing.” A single center pivot irrigation installation and pump station refurbishment project was completed for the Agricultural Development Agency in KwaZulu-Natal. Bosch Munitech was commissioned by the Department of Rural Development and Land Reform in Limpopo for the green-fields construction of a pump station and a three-

New close-coupled pump from KSB PUMPS

KSB Pumps and Valves recently added the new generation Etabloc close-coupled pump range to its line-up of efficient water pumps.

he newly enhanced series comprises 43 pump sizes, which can be driven by either 2-pole or 4-pole motors. With further additions to the selection chart, the pump size can now be selected even closer to the best efficiency point. KSB close-coupled pumps have applications in a wide range of industries including agriculture, industrial and municipal water pumping. Different material types and seal and nozzle types available for the range also extends its usage into other materials ranging from foodstuffs, to chemical, waste and a number of other usages.

More versatile According to KSB Pumps and Valves regional sales manager, David Jones, the discharge nozzles are fitted with more connection options for pressure gauges as standard, so several measurements can be conducted at the same time. The flanges of suction and discharge nozzles are optionally drilled to EN 1092 or ASME dimensions, for all materials. A large variety of nozzle positions and installation options enables maximum flexibility. Confined gaskets ensure reliable sealing between pump casing and casing cover, even in highly varying operating conditions. Another feature of the updated type series is its particularly service-friendly design. The conical seal chamber, for example, allows easy access and provides more space for maintenance work. The new, spacious design facilitates dismantling and reassembly of the mechanical seals. Forcing screws provided at the lantern make dismantling of the drive train much easier. Easy-to-replace casing wear rings protect the impeller and the casing cover from wear.

Low energy The drive lantern comes in standardised mating dimensions, offering the operator maximum choice in selecting an electric

motor. In line with KSB's common practice for industrial pumps, every pump will be supplied to the customer with the impeller diameter trimmed exactly to the duty point. Impeller trimming combined with the large range of pump sizes available for selection is the only way of keeping the pump set's energy consumption to the minimum necessary. The latest generation of the Etabloc type series meets strict global standards including the EU requirements of Commission Regulation 547/2012/EU for water pumps.

eDART dart valves and process control samplers enhance plant efficiency at Booysendal plant eDART dual valves and poppet samplers continue to offer exceptional level control at Northam’s Booysendal plant near Lydenburg, Mpumalanga.

DART Slurry Valves Director, Richard Rule commented “When Booysendal was originally built in 2010, we supplied dual dart valves and poppet samplers, and continue to be involved in the commissioning and aftersales support to Booysendal who have sourced additional samplers from us over the years. Our dart valves have kept the level error to less than 2.5% over an eight hour period at this plant. This is a great and important achievement as level control is vital in order to maintain the required ‘grade’ of the concentrate”. “External dart valves were initially chosen for flotation level control to concentrate the metal from ore, and they currently have 27 flotation machines each fitted with a dual dart valve. It can be argued that this is the most important valve on a concentrator as it is the last controlling element that determines if the metal reports to the concentrator or is lost to the tails”. “Booysendal have commented that our dart valves offer the best level control they have experienced on a plant” commented Rule. “We do not just sell our product and

walk away. We offer a considered assessment of valve requirements to our customers, and throughout the first year of operation, after our original installation at Booysendal, we assisted in the optimisation and fine tuning of the plant to ensure that the best possible performance was obtained from our valves”. Driven by the need for improved efficiency and throughput, good concentrators continually evolve. Samplers play an important and useful role in the monitoring system required to direct this evolution. “The Booysendal plant in particular has been very proactive in using our samplers and analysis to improve their processes. I believe eDART’s valve technology played a role in Northam’s improved results at their Booysendal plant due to their superior quality” said Rule. Brian Whitehead, Plant Superintendent: Technical at Booysendal added “Through the proper sizing of valves, we have been able to increase our feed rate to the plant without any major control issues on the valves”. Together with Afrivalve, part of the eDART Group, eDART were responsible for servicing and maintenance of equipment at the Booysendal plant which included all the calibration and servicing of their valves to maintain optimised operational efficiency. Other control loop elements also had to be correctly selected, calibrated and tuned in order to ensure peak plant performance. eDART are specialists in the design and manufacture of slurry equipment and offer external and internal dual/ single dart valves, as well as pinch, dosing and slurry valves; pneumatic actuators, instrumentation, samplers, flow analysis technology and related accessories.

ARVALV through-port knifegate valves for abrasive, scaling applications ARVALV through-port knife-gate valves have long been the product of choice for challenging abrasive and scaling applications at plants and facilities where extended service life is a must.

he ARVALV range is manufactured, stocked, and serviced by AR Controls, a leading importer and manufacturer of a comprehensive range of internationally-recognised valves and instrumentation. The company also boasts the largest product inventory of any similar company in Africa. â&#x20AC;&#x153;The fact that we are a leader in the African valve industry means that we can back-up our ARVALV range with dependable service, in addition to offering competitive pricing and good lead times,â&#x20AC;? AR Controls Director Julien van Niekerk comments. A particular design feature of the ARVALV range is that, unlike traditional push-through knife-gate valves, the partiallyenergised seats remain in their natural state when the gate is retracted. This is due to the unique through-port gate, which makes permanent contact with the seats, even when fully open. Slurry knife-gate valves utilising fully-energised sleeves that need to expand sufficiently to form a seal with the gate retracted are prone to premature wear due to entrapped solids, which damage the seat the next time the gate is closed,â&#x20AC;? AR Controls Mechanical Engineer Sune Huyser explains. This problem is eliminated by featuring a through-port gate, which not only results in an extended service life, but increases plant availability as well. The ARVALV range has been tried, tested, and proven to deliver superior performance in the following: dewatering slurries (such as ferrosilicon), cyclone suction/feed applications, dense media separation, concentrate transfer, booster and TSF tailings, pump isolation

2.64 Billion people do not have access to adequate sanitation. 780 Million people do not have access to improved water sources. More than 800 Children die Daily due to preventable water and sanitation-related diseases! These statistics are rather disturbing, so the question is simple ... how do we set sustainable development goals for our country? World leaders have agreed to 17 Global Goals that would mean a better life for all of us. The goals are a plan to build a world where children don't go to bed hungry, where girls get the same opportunity to thrive as boys, and where people don't die of preventable dieseases. It's one of the most incredible to-do lists ever written. The challenge is to turn these words into actions. If we focused on the availability and sustainable management of water and sanitation consider this: More people have access to mobile phones than a toilet - a staggering 2.5 billion don't have decent sanitation facilities. This isn't just inconvenient, but instead deadly! Diseases caused by dirty water and poor sanitation kill every minute of every day. In parts clean water is hard to find, it's overwhelming to imagine people spending hours every day walking miles to fetch water. Achieving this goal could change that, it would not only reduce illnesses it would help getting children into school and free up adults time which could boost the global economy by R416 billion a year. As long as poverty, injustice and gross inequality exist in our world, none of us can truly rest. Nelson Mandela

SKF enters the world of manufacturing using worldclass digital technology SKF's operations in Sweden are set to be given a boost with the inauguration of a completely new, fully automated digital production process in Gothenburg, adapted for the manufacture of spherical roller bearings.

he new production unit is the first of its type to be put into operations within the SKF Group and is part of a programme of next generation manufacturing technology within the company.

"The new production unit will open up new possibilities for us to reduce lead times and to improve flexibility and efficiency in our production," says Sten Karlsson, project manager for the new production unit.

"The production flow is totally unique within the bearings industry, and constitutes a new manufacturing standard for us, which we will replicate into numerous facilities within the Group. The investment programme is important for us if we are to utilise our manufacturing capacity even more efficiently, as well as increasing our global competitiveness and the flexibility we can offer our customers," says Luc Graux, Director of Manufacturing for the SKF Group.

Parallel to the investment in Gothenburg, similar investments are planned for Schweinfurt in Germany, Nilai in Malaysia and Flowery Branch in the USA.

Using the help of digital technology, the entire value chain in the production process is connected, from the inflow of input components to the delivery of the product to the end user. In addition, the next generation of mobile infrastructure is combined with the manufacturing process, in order to enhance efficiency.

Pipes, Pumps and Valves Africa - Nov/Dec 2017

Over a million bearings per year are manufactured in the Gothenburg facility. The majority of these are exported. The products are used in heavy industry, such as mining, steelworks, paper machines, wind turbines, train gearboxes, fans and pumps.
