Unleashing the great game

At the football world championship in Russia, 736 players from 32 different countries are battling it out for the biggest prize in world football. It is a month of nerves and drama, as some nations burst with joy, while others weep in despair – you might say it’s a Russian Roulette. Behind the scenes, Grundfos has played a significant part in ensuring a troublefree execution of the tournament. The world’s attention is on these elite athletes fighting tooth and nail to bring glory to their country and their compatriots watching anxiously at home. But in order for these players to perform on the biggest stage, it’s important that everything on said stage runs smoothly. Grundfos has contributed to ensure that all the stadiums used during the tournament create the best possible conditions for both players and spectators.

Dual Products International – local manufacturers of slurry valves for over 30 years – has become one of the world’s leading producers of abrasion resistant valves. “BMG’s strategy to expand its fluid technology services to meet growing market demand, incorporates the introduction of new products, with the latest developments in design technologies, materials and coatings,” explains David Dyce, business unit manager, Fluid Technology, BMG. “The addition of Dual Valves products to BMG’s portfolio enhances the company’s solution services and broadens BMG’s customer base, providing new market and application opportunities.

Typical applications of Fibertex Formtex® CPF liners are in drinking water tanks, sewage and water treatment plants, settlement tanks, container terminals, bridges and tunnels, marine structures, as well as dams and sluices. Formtex is a two-layer CPF liner, consisting of a drainage layer that allows water and air to escape and a filter layer with a pore size designed to retain cement particles. When surplus water and air is drained from the surface of the freshly poured concrete during compaction, the water/cement (w/c) ratio in the concrete cover is reduced. This results in a denser and stronger concrete, with a blemish-free surface.

All around the world pump asset owners and operators are continually pushing for the next performance bump. Finding ways to minimize profit losses while improving pump performance and operations, amidst trying  economic times, has not been easy. New technology offers the opportunity to innovate and provide full pump solutions, taking operations to the next level. The global pump market has seen some real volatility in recent
years thanks to declining oil and commodity prices. Finding new ways to impact on efficiency, effectiveness and
overall competitiveness, has become increasingly difficult.

Driven by factors such as business intelligence and advanced analytics, the global Industrial Internet of Things (IIoT) is growing at a rapid pace. Whilst IIoT analytics are being widely used in various sectors including  manufacturing; healthcare; energy and retail, the pump sector has been slow to the party. Moving it to the top of the agenda should be the priority. New technologies enable a deeper, ongoing understanding of equipment system performance, potential equipment failures, and specific environmental factors that may contribute to equipment under-performance or failure. These technologies include growing availability of sensor data, less expensive data acquisition and storage, cheaper computing technology, and the wide availability of machine learning and data science tools and techniques to rapidly analyze, understand, and improve system reliability.

With more focus on building energy efficiency, building owners often rely on consulting engineers to specify efficient pumping solutions. For variable flow systems, this poses some challenges when parallel pumps are being evaluated. A recent international webinar by Reece Robinson of Grundfos Pumps Corporation hit the pause button to review some of the fundamentals when talking about pump efficiency and control. From the get go, before one can talk about efficient pump selection and control, it is essential to understand the pump performance curve, says Robinson.

Jeremy Hanhiniemi explores four unique pump design considerations which should be optimised in mobile mine dewatering pump designs. There are a number of essential factors to examine including operating and fuel costs, pump efficiency and wear, pump unit capital costs as well as diesel engine factors and performance.
In both underground and above ground mines, quarries, and construction sites, water can accumulate and
interfere with operations, necessitating its management and removal. The process to achieve this is referred to
as dewatering. Water is essential to mineral processing to recover valuable ores. Following their extraction, large sediment or tailings ponds are used to collect the tailings laden water from these processes.

KSB Pumps and Valves has assisted the University of Pretoria in the construction of a large controlled-temperature test unit, which will form the backbone of ongoing research into heat transfer, fluid mechanics and thermodynamics. The impressive unit will allow students to plug directly into hot, moderate or chilled liquids to use on research projects and will shave approximately 50% off students’ overall project build-up time thereby
allowing more time to carry out actual research.
In addition, it is expected to save considerable costs in future.

Emerson’s Plantweb™ Insight application provides streamlined view of networked Rosemount™ wireless pressure gauges, helping maintenance personnel stay informed and safe. Emerson announces a new Plantweb Insight application for wireless pressure gauges that displays data in an easy-to-understand dashboard for maintenance leads and instrumentation and electrical (I&E) personnel. An entire suite of Plantweb Insight
applications collectively helps users quickly make sense of plant data and drive overall enterprise profitability.

Schneider Electric’s international knowledge on the water and wastewater industry and its ability to break barriers and connect ideas will be demonstrated this at the Water Institute of Southern Africa (WISA) biennial conference and exhibition. “The theme, ‘Breaking barriers, Connecting ideas’ is an integral part of Schneider Electric’s ethos, working as we do across both the developed and developing worlds,” says Marc Ramsay, Vice
President for the Industry Business Unit at Schneider Electric South Africa. “We have adapted our systems to meet those challenges found on the ground at water utilities and further upstream. For instance, the Villaya Solar Water Pumping Solution is a fully automatic system, designed to provide water at affordable cost for people with limited or no access to electricity.

Surcotec’s metal spray coating solution has extended the life span of a Labyrinth casing thereby avoiding the need for costly replacement, leading to significant cost savings for key customer, Eskom, at its Palmiet Hydro  installation. The power station is located near Grabouw in the Western Cape on the Palmiet River, 2km upstream of the Kogelberg Dam wall. The Palmiet Pumped Storage Scheme is part of a water transfer system. For generating purposes, water is released from the upper Rockview Dam to the two reversible pump turbines located 60 metres below ground level. Surcotec was requested by Eskom to submit a recommendation and procedure to prepare and coat the top runner Labyrinth on unit 1 of the Turbine at Palmiet.

Staying ahead in an industry as competitive as pump rental requires a comprehensive understanding of dewatering application requirements. It also necessitates a pump rental fleet that can meet the needs of different market sectors. Integrated Pump Rental recently bolstered its pump rental fleet with the inclusion
of a range of stainless steel submersible pumps. Managing director, Lee Vine says this was done to specifically cater for applications where there are increased levels of acidity in the water. “Acid water drainage on mines is common today, and these extremely harsh dewatering applications require an appropriate pumping solution which is why we have added Faggiolati stainless steel slurry pumps to our rental fleet,” Vine says.

South Africa’s Vesconite reflects on a recent trip to Spain. A recent trip to the Spanish pump manufacturers by
bushings and wear material supplier Vesconite has resulted in several large orders of bushing material. This is according to Vesconite technical sales representative Phillip de Villiers, who is spearheading the company’s
European pumps business. “This month we received orders for considerable sums,” he notes. “One company ordered stock material of extra-large bushings that it will machine into wear rings for its own use, while another ordered bushing material to machine into bushings for its original-equipment-manufacturer pumps.”

In order to improve the froth level control at a flotation concentrator in Rustenburg, eDART was recently commissioned to replace the froth level control valves on the secondary cleaner. Froth level control is extremely important on flotation machines as it directly relates to efficiency of the plant. If the froth level is too deep then the grade of the concentrate will increase, and at the same time recovery drops off. When the froth level is too shallow the recovery will improve but a lot more concentrate will be produced at a lower grade. The aim is to produce concentrate at the optimum grade, which will result in the highest efficiency of the plant.

The storage of flammable liquids carries with it the need to put in place fire protection mechanisms. Tank blanketing is deemed one of the best and effective ways of preventing fires in flammable liquid storage tanks
by means of controlling the formation of explosive vapour or air mixtures above the liquid surface. The threat of fires in flammable liquid storage tanks is not far-fetched. Fires can occur at any time for many reasons. Therefore, it is vital to safeguard both human life and material assets from the destructive effects of fires. Tank blanketing valves provide an effective means of preventing and controlling explosions in flammable liquid storage tanks.

Pure Technologies completes longest single day pipeline inspection to date using PipeDiver® technology. From the Colorado town of Buena Vista, the views of the distant Rocky Mountains are deceptively stunning. Up close, the terrain is hilly, inhospitable and extremely remote. With no roads and little access, this is helicopter, snowmobile and 4-wheel-drive country. As might be expected, the logistics of inspecting a water pipeline that runs through this unforgiving territory makes the inspection extremely time consuming and hazardous for everyone.
