SUPERBOLT TENSIONERS’ PUMPS & PUMPING-EQUIPMENT

BMG’s Superbolt® Multi-Jackbolt tensioners, which form part of the Nord-Lock range, are designed to reduce down-time and eliminate unsafe and laborious bolting methods for pumps and pumping equipment.

the separating forces means bolting will not vibrate loose on properly designed joints – this eliminates costly downtime. Added elasticity increases fatigue life of the bolted joint. Installations are safe because only small hand tools are required. This means there are no safety hazards from immense hydraulic pressures, no pinching hazards, no need for the lifting of large tools or sockets breaking under high pressure.

“Multi-jackbolt tensioners are easy to install, even in confined spaces, and although there are multiple jackpoints to tighten, installation times are faster than other bolting methods. “shared Ryan.

“

These multi-jackbolt tensioners replace or retrofit nuts and bolts on pumps and only require hand or air tools for installation and removal of any size tensioner,” says Ryan Bassett, Senior Product Manager, BMG’s fasteners, tools and equipment division.. “Bolts on pumps and pumping equipment need to be easily removable during maintenance procedures, but must also resist the loosening effects of vibrations and dynamic loads.

“This quick and efficient bolting method is based on a design which splits one big torque into a number of smaller ones. Superbolt, which has numerous advantages over conventional bolting products, ensures joints can be tightened with high accuracy, without need of specialist skills or heavy tooling. Tightening in pure tension allows higher preloads on the same size bolt than conventional tightening methods.

“By generating a preload high enough above 4

Pumps and Valves Africa - Q4 - 2015

A conventional bolting system, such as the sledgehammer, gives little control, is inconsistent and can cause injuries. Thermal tightening, crane and hydraulic wrenching and hydraulic tensioning are often costly, inaccurate, time consuming and unsafe.

While Superbolt tensioners are available in standard sizes, from M16 to over M1450, a large number of sales are for special non-standard items. This range is also custom designed and manufactured in various materials to required specifications for diverse tightening applications.

These multi-jackbolt tensioner are designed for demanding applications requiring a high clamping force and with limited space for tightening the bolts. They are also perfectly suited for harsh underground mining conditions.

Superbolt tensioners are used in diverse industries, including hydropower, wind turbines, gas and steam turbines, nuclear, steel, mining, shipbuilding, offshore, chemical and transportation. OEMs specify Superbolt multi-jackbolt tensioners in their design to improve performance of their product.

BMG offers a technical advisory service to determine the dimensions and load conditions of existing or required bolted joints. Current tightening methods are evaluated and bolt preloads for absolute reliability and durability are calculated.

fact that many people do not know, (unless you are in the pump industry) is that pumps play a key and vital role in all our daily lives. Pumps are also large consumers of our daily energy resource since most of them need electricity to run.

This, in itself is a challenge especially in critical installations, over and above the recent drought issues. Knowledgeable people will take this factor into account when making an informed decision with regard to pump selection and manufacturing.

It is for these reasons that it is important to keep training as one of the key factors of the association.

Training is a contentious issue because of the cost, level offered or what value it adds to any orga6

nization. For these reasons, we as an association have sought key trainers with accreditation in their field and the subject offered. It is important to ensure that the training offered is value for money, as well as something of value to add to a CV or in line with job requirements. For this reason, our Advanced Pump Training course is CPD point accredited and students will write a test after the course to establish that they understand the knowledge learnt to receive their certificates.

This course is the first of what we plan going forward, but like so many of these initiatives, they take time to put in place if we want to do it correctly and to an esteemed standard.

Some of the large pump companies in South Africa are members of SAPMA, with supporting industry companies who are also members. Since SAPMA is affiliated to SEIFSA, it ensures all employees of these companies are represented in the steel and engineering industry.

Today our members employ over two-thirds of the industry’s workforce making SEIFSA one of the largest and most influential federations in South Africa.

By joining SAPMA you too can become part of a powerful body of employers working together to further common interests. This is becoming more important in these economically challenging times where collaboration and collective representation is required for the existence of business.

CONMESA-THIRD-QUARTER-2015-INDUSTRYCOMMENT “In spite of tough conditions in South Africa’s mining and construction industries throughout this year and further deterioration of activity in the third quarter, there are signs that give a glimmer of hope for a more stable economy in 2016.”

“Over 14 000 visitors from approximately 75 countries attended this four day event, which provided the ideal platform to stimulate trading between African and international companies.”

Other positive trends recognised by CONMESA in the third quarter include a rise in sales in the plant hire sector and the continued growing trend towards ‘rental with option to purchase’ options, rather than the investment in new equipment, as was previously the case. There is also a shift by end users to commission OEM’s to maintain equipment through formal service and maintenance contracts, as opposed to in-house maintenance teams.

Association members have identified that weak economic growth in the third quarter of 2015 is a consequence of extended labour strikes, high wage demands, lethargic investor confidence and ongoing power shortages.

A further concern is the negative impact of Government policy on the Rand which members acknowledge should not be ignored, as affordability is becoming a serious constraint to OEM’s.

T

his is the view of Stefan Otto, chairman of the Construction and Mining Equipment Suppliers’ Association – CONMESA.

“Members of CONMESA believe the Government’s recent launch of Operation Phakisa should provide new business prospects and kick-start an upturn in 2016. Operation Phakisa, derived from a Sesotho word meaning ‘hurry up’, is an initiative aimed at accelerating the delivery of economic transformation priorities, encompassed in the National Development Plan (NDP).

“CONMESA also recognises new business opportunities that have been generated from Bauma Conexpo Africa 2015 – an international trade fair held in Johannesburg recently for construction machinery, building material machines and mining and construction vehicles.

The significant decrease in activity in neighbouring countries, which rely on stable commodity prices, has also had a negative impact within South Africa.

Commodities, including coal, copper, cobalt, zinc, nickel, chromium and manganese, are key exports of Zambia, Namibia, Botswana, DRC and Mozambique, which have seen a drastic downturn in equipment sales.

CONMESA members are however cautiously optimistic, that if union issues are resolved ahead of pending strike action and if Operation Phakisa delivers on its promises, this should be sufficient to prod the start of an economic upswing in 2016. In addition, a boost to worldwide commodity prices and energised investor confidence would certainly help.

llmost every mine, water is a problem. It trickles and flows down to the lowest points, such as shaft bottoms and disused tunnels, dams up, overflows, and generally interferes with mine operations – if not managed.

Regardless of a mine’s location, be it in an arid area or not, water seepage and flow is a problem because it impacts on a mine’s production, ground control and safety.

While mines focus on their primary objective of getting ore out of the ground they also need to pay attention to worrisome issues; such as water drainage and collection and disposal, especially in unused areas of the mine and before

it becomes a problem. Fortunately, most if not all mines do, and have effective water management plans in place.

A recent visit to the Beatrix Gold Mine in the Free State, revealed the careful thought that had gone into their water management plan, which took into account factors such as their local climatic conditions, the hydrologic and hydrogeologic characteristics of the mine area, their mining methods and mine depth, and with careful thought about environmental impacts. At Beatrix, water is a high priority. Their environmental initiatives, operating a closed water circuit, are focused on reducing the impact that the mine may have on the environment through concurrent rehabilitation and responsible water management. All potential sources of pollution like the water discharges are monitored and sampled on a regular basis.

Throughout Beatrix, water is channelled to collection points where sump pumps pump the water to bulk collection points and from there up to the surface for processing and recycling. This approach effectively automates the process and it requires little supervision.

Throughout the Beatrix mine, and not just down at 1341.5 meters below surface where the NASA team were on the hunt for living organisms, Beatrix has to take precautions against methane gas. As such their air conditioning system blows air through the tunnels at a constant rate of knots, which is equivalent to a light breeze. This moving air picks up dust particles and, with static around, attaches to every surface and permeates every nook and cranny possible. Sump pumps need to be impervious to the dust, and run, constantly. It’s an environment that quickly sorts out the men from the boys and, to be politically correct, the women from the girls.

SOUTH AFRICAN PROJECTS COMPANY COMPLETES MALAWI PUMP STATION REFURBISHMENT APE Pumps has completed a major portion of the €16 million upgrade project being financed by the World and European Investment Banks to rehabilitate pipelines and pump stations supplying water from the Shire River to Blantyre, Malawi.

The work comprised two separate contracts awarded by the Blantyre Water Board, together valued at some R200-million and managed as turnkey projects shared between the company’s Johannesburg works and the Kolkata factory of holding company Worthington Pumps India.

APE Pumps controlled all phases of both projects from tender, through design and manufacture, to installation and commissioning.

The official handing-over ceremony to the Blantyre Water Board is scheduled for the end of October.

The first and larger of the two contracts, to upgrade the Chileka pump station, was awarded in April 2013. It was followed in October by a contract to complete the upgrade of raw water and high-lift pumping stations at Walker’s Ferry, begun by a foreign company that defaulted

soon after delivering components and equipment to site.

APE Pumps remains one of only a handful of South African pump companies actively seeking turnkey project work, with most competitors preferring to restrict themselves to pump supply only.

Pumping Coal Whether it’s a short distance, in meters, or a long distance, in kilometers, or as in some cases, hundreds of kilometers, pumping coal is a practical and efficient transport alternative. The secret is in the pump, and the slurry.

here is nothing like a problem or obstacle to focus the mind on solutions. And, as with most challenges, almost all can be solved with enough money. This, it would seem, is one of the indomitable laws of our modern world. However, there are times when there isn’t quite enough money to put the perfect solution in place and other times when the best solution does not cost quite as much as anticipated.

Even so, problem solving requires innovative thinking. Geinrich Altshuller, the father of The Theory of Inventive Problem Solving, established the first law of innovation – look elsewhere for your solution as someone else has probably solved your problem already. In many cases this is really good advice.

In the case of the Chirodzi mine in Mozambique, an opencast coal mine with a proven reserve of 700 million tonnes and an expected life-of-mine of 25 years, and with a 2020 production output target of 100Mtpa, Altshuller’s advice was spot on. To get their coal from the Moatize in the Tete Province in the North-west of Mozambique to the nearest port, Beira, Chinde, Macuse

By Tony Stone or Nacala, and reach their 2020 delivery target, a reliable and cost-effective logistics solution was needed.

Road, the first solution, which out of necessity was selected as the startup option, could only be run as a solution in the shorter-term. With the 570 km road already in a poor condition, which would need a major overhaul at great expense and time, road transport is the most expensive logistics cost per tonne solution and therefore not sustainable.

Rail, the second solution, has its problems. Malawi extends south so much that a railway line from Moatize in the Tete Province to Nacala would have to go around or through it. Through Malawi is the shortest route but this requires 33 bridges to be rehabilitated and or strengthened and 65 new bridges built, besides the rail line construction itself, all at a cost of $3.4 billion. The Chinde route would take the rail line alongside the flood plains of the Zambesi River and after the floods of 2013 and 2015, the risks associated with this line are ever present. The Macuse option, a small coastal port about 120 km up

the coast from Chinde is a good alternative but, despite it being a shorter route and out of the Zambezi flood plains, the costs of a new line, countless culverts and new bridges will add yet further time and costs to the logistics project.

However, and together, these rail solutions will only provide a combined 60Mtpa carrying capacity, 40 Mtpa short of the Chirodzi 2020 requirement. Then there are all the other mines that will want to use the same rail routes, putting pressure on the design capability of these rail routes If one used the Zambezi River itself a third LSA pumps in service at Minera El Roble Plant in Durango, Mexico transport solution and barged coal to the Port of Chinde, this would only add 20Mtpa to re- projects around the world, have perfected the technology. quired total logistics solution of a 100Mtpa. So, quite The large pipe is for the slurry, the small pipe is for simply, an additional logistics solution is required.

Consulting engineers, ARUP, proposed the forth solution - the construction and operation of Africa’s first coal slurry pipeline to transport coal from the mine to one of the ports, over a distance of several hundred kilometers. Has this been done before? Yes, it has. But, as with all pioneering technologies, initial projects produced less than satisfactory results. Protagonists were quick to write this off as a solution. However, after going back to the drawing board, engineers in the USA, and in other

The world’s longest slurry pipe line, 400 km in length, is operated by Alegria iron ore mine, Brazil. The slurry flows at an average speed of 6km/h with a flow rate of 1200m³/h.

The pipeline, designed to move 12 Mtpa, is now operating at over 15 Mtpa owing to advances in pumping and monitoring technology. No doubt, because of the sharp drop in commodity prices, the Chirodzi mine has scaled down on its production and the pipeline has yet to be built. Nonetheless, building on existing slurry pipeline successes,

ARUP’s proposed coal slurry pipeline features included: * Uses fresh water from Zambezi River or sea water from the ocean * Dual pipeline principle can be followed with the large diameter pipeline for coal slurry, small pipe line for water return with 70% of water recycled. * Closed loop system to minimise water loss. * Particle size of at least 4 to 7 mm for fresh water transport and up to 50mm for seawater (dense medium) transport. * Pipeline slurry of 50% to 60% solid by weight. * One main pump station and one booster pump station to overcome friction. * Capital Cost per km: US$ 9. 2 Million. * Operational Cost: Assume 35 MW power. Fixed Cost (pa) US$ 30 million Variable Cost (per ton) US$ 0.5 * Expected Transportation tariff: US$ 20/ton Pumping a mix of coal, magnetite and water as a slurry down a 570 km odd pipeline would need a capable and re-

liable pump set, with pumps installed in series, to keep the flow constant and prevent solidification down the pipeline.

Rob Bond of KSB Pumps’ mining division said, “Because of the high pressure and abrasiveness of the slurry, a high chrome metal pump, such as the KSB LSA Extended version, would be needed. The LSA Extended series pumps are low maintenance, abrasion resistant, heavy duty service pumps and are perfect for coal slurry applications.”

No doubt other pump manufacturers have similar pumps to offer. Nonetheless, in the final analysis, slurry pipelines are the cheapest form of coal transport. It is a solution that coal mines in South Africa should be considering when it comes to delivering coal to Eskom – to keep the price of electricity down. It’s seriously worth a consideration.

Clean Drinking Water with Xylem’s Aquada UV Systems

The global team for Wedeco; one of Xylem’s flagship brands; have developed another industry-leading product in their new Aquada UV-range. The Aquada UV range uses ultra-violet (UV) technology to eliminate bacteria in drinking water. These systems have been specifically developed for residential and commercial applications and are also available in South Africa.

Although water delivered to homes and commercial zones is usually treated with chlorine or other processes, certain micro-organisms can survive and make it into water used for bathing; w a s h i ng an d drinking. While most of these micro-organisms are harmless, there are quite a few that are harmful and are capable of causing severe illness.

UV is by far the most effective way to render these micro-organisms harmless UV is by far the most effective way to render these micro-organisms harmless. While other home water purification systems improve the taste and clarity of drinking water; Aquada UV systems employs UV-technology to eliminate micro-organisms and improve water safety.

There are several benefits to using the Aquada UV-technology for homes and businesses. Apart from the overall water safety being improved; it is low cost and easy to install. The Aquada-system is simply connected to the main water supply line and then provides UV-treated water to all the water outlets on the premises. There are also no harmful by-products and the taste and ap14

pearance of the water is not affected by the UV-treatment. UVlamps are also easy to replace and only requires replacement after a full year of use.

Aquada UV-systems are available in three distinct models – Altima (economy); Proxima (medium spec) and Maxima (high spec). Each of these are available in five different sizes for homes or businesses; depending on the amount of purified water required; i.e. a hotel would require a high specification Maxima model; whereas for a standard house the economical Altima model would be the best fit.

Xylem Water Solutions now offer South African clients the opportunity to obtain these affordable UV-systems throughout the country. Technological innovation within the water cycle is forever top of mind for Xylem – both globally and here in South Africa. The company boasts a range of world renowned pump-and-water treatment systems within its stable; including Wedeco; Flygt; Leopold; Lowara and Sanitaire among others.

The new Aquada UV-systems underscore Xylem South Africa’s commitment to provide global technology to clients and to ensure that tailor-made solutions are available to clients operating within every part of the water cycle.

FRANKLIN ELECTRIC SOUTH AFRICA LAUNCHES MONO EZSTRIP™ TRANSFER PUMP Franklin Electric South Africa, a leading manufacturer of world class pumping solutions with expertise throughout the African continent, has launched an innovative, cost-saving, new range of progressing cavity pumps into the Southern African market.

T

he revolutionary new Mono EZstrip™ transfer pump is easy to install and presents the opportunity to see downtime drastically reduced as maintenance, cleaning and repairs to the pump can be carried out in-situ.

The new pumps do not require any special tools or operational skills and can be refitted into existing applications. The development of the Mono EZstrip™ transfer pump has been recognised as one of the biggest leaps forward in progressing cavity pump design in 30 years.

Extensive research was carried out before the development of the Mono EZstrip™ transfer pump which took into consideration various factors, among them the typical problems faced by customers in the waste water industry. From this global research it was established that the two biggest hurdles clients came up against when using conventional progressing cavity pumps was the need for a greater handling capacity and the inconvenience of maintenance downtime.

While standard progressing cavity pumps have to be dismantled and taken away to be serviced, the new EZstrip™ technology provides for a simple and efficient Other advantages of the new Mono EZstrip™ transfer pump include: ◊ The pumps can be supplied on base plates for ease of installation ◊ They are available in cast iron or stainless steel with a choice of rotor and stator materials to suit individual application. ◊ A pre-assembled drive train is available with a two-year warranty and allows for even faster re-assembly time ◊ As maintenance downtime is reduced, labour saving is increased ◊ New technology eliminates the need for dismantling lengths and greatly reduces the space needed for maintenance to take place ◊ The optional dry run protection can further reduce maintenance costs and increase uptime.

way to disassemble, de-rag and maintain the pump in-situ without having to dismantle suction and discharge pipework. All rotating parts can be easily removed and de-ragging operations require only a spanner and Allen key. As such, routine maintenance that would have taken the better part of a day to complete can now be achieved in under 30 minutes. Currently the removal of rotating parts from a progressing cavity pump can take up to a full day; however, with the EZstrip™ transfer pump the entire drive train including rotor, stator, shaft, rod and seal can be removed in less than four minutes. Furthermore, the new Mono EZstrip™ transfer pump has a handling capacity of up to 225 m3/h.

The versatile and reliable Mono Pump was first introduced in South Africa in 1968 and over the years has proven to be highly popular with the mining, petrochemical, pulp and paper, sugar, waste water sewage and agricultural and irrigation sectors, among others.

The revolutionary design and easy application of the new Mono EZstrip™ transfer pump reinforces Franklin Electric’s outstanding reputation as a leading manufacturing supplier of world class pumping solutions.

Getting all pumped up Economists argue, between themselves, whether supply determines demand or whether demand determines supply. In water supply engineering, the position is quite clear – demand determines supply, and a few other things in the process.

P

hysics is a fascinating subject, and engineers are smart enough to apply its laws in a number of really clever ways, one of which is to reduce costs. The benefit to clients, such as Rand Water, is of course advantageous, especially with Eskom struggling to provide enough electricity to keep up with consumer demand.

So, with proactivity rather than reactivity a desperate need in service delivery, it is great to see considered thought and forward planning going into what is an essential service – water supply.

Working on a 20-year planning horizon, Rand Water is driven by forecasts of future water consumption needs and the need to maintain the capacity of existing infrastructure. Trends and usage patterns are analysed, the condition and performance of infrastructure assessed, compliance with evolving legislation verified, and discussions with various stakeholders on their expectations, is a continual process – es-

At the moment Rand Water are busy with various water supply projects, one of which is a R1.3 billion 2.1 m diameter pipeline project from its Palmiet Pump Station in Alberton, along a 14.2 km route, through to the Signal Hill Reservoir in Primrose, Germiston and along a further six kilometers on to the Klipfontein Reservoir. This project started in May 2014 and is expected to be completed in the first quarter of 2016. According to Justice Mohale, Media Relations Manager at

How does one determine the diameter of a pipe and the size of a pump required to meet consumer demand Rand Water, the new pipeline is being constructed to replace an old existing concrete pipeline.

The new pipeline will also assist in augmenting the system due to an increase in demand.

So, how does one determine the diameter of a pipe and the size of a pump required to meet consumer demand. And, at the same time, how does one do this optimally, and minimize the concomitant consumption of electricity?

This is where physics comes in. The rule is, the smaller the diameter of the pipe the greater the velocity (but not the volume) of water through the pipe and thus the greater the power consumption given the pump requirement. The opposite is also true – the greater the diameter the less the velocity (but the greater the volume) and the less the power consumption. Added to which is the pipeline length (distance), the total volume of water (taking into account water hammer, the backward and forward motion once the pumps are switched off, which can create negative pressure) and the height differential between source and destination (friction, as measured in meters). By placing two pumps in series (in line), the first pump serves as

The above diagram illustrates the configuration of two pumps installed in series

the main pump and the second as the booster pump.

For example, with a megaliterage demand of 200 Ml per day using a 2.1 m diameter pipe as the transporter, one would install a two stage (in series) axially split casing (for easy maintenance) centrifugal pumps.

The first pump, the main pump, could typically be a Sulzer low pressure HPDM 600-680 Axially Split Casing Pump with a 600 mm outlet pipe and equipped with a 680 mm impeller. This type of pump is used to transport large volumes of liquid over long distances and high geodetic (shape, orientation and gravity) heights. Water, crude oil and any other high flow, high head applications are typical. These pumps, which combine efficiency, reliability, ease of installation, operation and maintenance, are well known for their longevity - just what is needed to minimize costs.

This pump is connected to the underside of a reservoir where the flow of water to the pump is regulated through what is called “available suction pressure” This is determined by the height or rather the depth of the water in the reservoir. In a typical 9.5 m high 20 Ml reservoir, and to maintain efficiency, the lowest that the water level may drop down to is 3.3 m. Two other interesting design aspects of the pipe into the pump are the flat top of the pipe (to avoid the accumulation of air) and the initial wide to narrowing section of the pipe where a “flow straightener” or stabiliser is installed to prevent water rotation/swirl (which would result in an unequal feed into the pump) .

The second pump, the booster pump, could typically be a Sulzer high pressure SMD 801-950 Axially Split Casing Double Suction Pump with an 801 mm outlet

pipe and equipped with a 950 mm impeller. The double suction design delivers less shaft deflection (due to the between-bearing design), a lower Net Positive Suction Head (NPSH) requirement (due to the fact that each impeller eye only handles one half of the total pump flow rate), virtually no axial hydraulic thrust (due to the back-to-back / double suction impeller design), higher efficiency (because power is not lost to balance the hydraulic thrust) and relatively high allowable nozzle loads (due to the rigidity of the lower portion of the casing).

These pumps, which combine efficiency, reliability, ease of installation, operation and maintenance, are well known for their longevity The NPSH is determined by the static head plus the surface pressure head, less the vapor pressure of your product, in this case water, and the friction losses in the piping, valves and fittings. It’s all very complicated but that is why we have engineers. Any water board or municipality that does not retain and/or employ suitably qualified and experienced civil engineers are failing in their responsibility to the people they serve.

Key Features Magnets are typically made of ceramic, samarium cobalt, or neodymium.

Bushings and thrust surfaces inside the can are made of silicon carbide or tungsten carbide, or ceramic, to handle the potentially abrasive liquid that circulates inside the can. Most must be protected against loss of flow, which could seriously damage the pump due to temperature build-up due to the magnetic flux.

Applications Used Pumping chemicals, hydrocarbons, or other liquids that are difficult to seal, or where the consequences of leakage are serious. Pumping heat transfer fluids which are high temperature or which are prone to costly evaporative losses with traditional mechanical seals.

Metering Pumps Basic Description

Key Features

Metering pumps are a type of reciprocating positive displacement diaphragm pump that has a very low flow rate (typically measured in gallons per hour or per day, rather than per minute). Flow rate is adjustable.

Pump is typically a diaphragm style, though older designs are plunger type.

Diaphragm is driven by solenoid, mechanical actuation, or hydraulic actuation. Pump includes inlet and outlet check valves. Normally contains stroke length adjustment to vary flow rate, and some pumps can also control flow rate with speed control.

Applications Used Used to meter or dose very low flow rates with high accuracy. Most common application is chemical treatment of water in boilers, cooling towers, potable water, etc.

Becker Mining offers a variety of Pumps to the market

Becker Mining South Africa’s extensive range of light, medium and heavy duty slurry pumps includes the HS range, available in vertical, horizontal and submersible configurations. These pumps are designed for optimum efficiency, low maintenance and extended service life in diverse industries, including harsh operating conditions.

coupled, overhead adjustable, or Z-adjustable belt drives.

HS and VHS pumps, with heads up to 40 m and flow rate capacities to 800 m³/h, can be achieved at speeds of 1 750 rpm. Solids to eight inches (203 mm) and S.G’s to 1, 5 can be handled. HTMS submersible pumps have capacities to 636 m³/h and heads to 28 m at 1 450 4 pole speed, with withstand temperatures to 90C and pressures to 1 380 kPa.

The HS pumps range, which is manufactured locally to stringent OEM specifications, includes four different models, in various sizes – from two to eight inch units. HS (horizontal hydro solids), VHS (vertical hydro solids), PVS (pumpmor vertical solids) and HTMS (submersible) pumps are ideally suited to many applications in mining, waste treatment, foundries and steel mills, paper and pulp, food processing, as well as power plants, agriculture and manufacturing.

“These hydro solid vortex pumps are designed to pump sludge and slurries containing large abrasive solids, trapped air and fibrous materials in light, medium and heavy service industries,” says Theo Cambanis, Becker Mining South Africa. “Due to the recessed, non-clog impeller of this range, solids and fibrous materials up to 200 mm (depending on pump size) can enter the suction inlet and be expelled through the pump discharge, without damaging the impeller.

“The PVS pump has a slightly different design, with a locknut locking the impeller to the shaft. This method prevents the impeller from turning off if the motor is started in the wrong rotation direction.”

HS pumps, in horizontal and vertical configurations, offer a flexible drive arrangement, including direct 58

Pumps and Valves Africa - Q4 - 2015

PVS pumps can handle solids to three inches (76 mm) and S.G’s to 1,5. Heads to 20 m can be achieved at speeds from 1 450 rpm and heads to 87 m at 3 000 rpm.

In all models, a robust one piece casing facilitates the flow of all types of solids and fibrous materials and an easily accessible stuffing box minimises blow-back of media around the shaft sleeve, without actual sealing contact.

The heavy duty, hardened chrome iron construction (650BHN) of the wet end of these pumps increases service life. Because all components are locally manufactured, these pumps are readily available and a large stock holding of spares and raw materials ensures swift delivery throughout the country.

Another advantage of the design of these pumps is that spares are completely interchangeable. This reduces inventory management costs and simplifies on-site repairs. The company is also able to adjust its extensive range of pumps to suit specific requirements.

Becker Mining employs a fully integrated ISO quality management system as part of a dedicated design, manufacturing, testing and repair facility.

The company’s extensive product portfolio also includes steel arch support systems, transport systems, rope attachments and communication and collision avoidance systems. The range also encompasses electrical and electronics systems, mechanical equipment, as well as lifting and maintenance equipment.
