speed and highest possible energy efficiency.” The e-PURE series sees reduced maintenance, lower energy costs, and a longer lifetime. The pump housing is manufactured from solid machined PTFE or PE (UHMW). The other wetted parts are made from PEEK and SS 316L. The e-PURE ensures a sustainable solution combined with all the typical diaphragm pump advantages. Because it is electrically driven, no expensive compressed air is required. This contributes to the overall lower energy consumption of this pump series. In e-PURE diaphragm pumps, the fluid moves through the pump horizontally. The electric drive ensures the reciprocating movement of the diaphragms so that the diaphragm chambers are alternately filled and pressed. This pump design uses flapper valves instead of ball valves. Overall, this ensures the speed of the fluid, and the energy efficiency of these pumps is optimal. n
Verder launches new range of double diaphragm pumps Verder Group recently expanded its range of Verderair diaphragm pumps with the launch of the e-PURE electrically driven double diaphragm pump series. Launched globally in April, these pumps are available locally as well as for Africa through Verder Pumps South Africa and its distribution network. A ccording to Darryl Macdougall, Managing Director, Verder Pumps South Africa: “The e-PURE series is a sustainable electrically driven diaphragm pump solution. Because of the reduced number of flow bends and moving parts, this new unique pump series has a much better fluid flow. The result is an optimal fluid Improving power plant maintenance
A s South Africa works to improve its power supply and stability, maintenance of power plants is receiving fresh attention. Werner Pumps, leading South African manufacturer of high-pressure jetting and vacuum equipment, says there’s a definite uptick in demand for the vacuum trucks used for power plant cleaning and maintenance. George Jolly, National Marketing Manager for Werner Pumps, says the company has supplied five trucks to date to three different power stations – two in Limpopo, and three in Mpumalanga (to two different power plants within the province). “The Werner Pumps Indlovu Vacuum Truck and Impi Wet/Dry Combination Vacuum and Jetting trucks are the most popular options for power plant maintenance,” he says. “The Indlovu unit is primarily being used for vacuum cleaning of wet and dry fly ash from the furnaces, as well as for sludges and slurries around the plants, and the Combi Vac Jet truck is being used for drain management within the plants.”
To date, Werner Pumps has supplied five trucks to three different power stations.
The Indlovu units are engineered specifically for fly ash, slag, and dry bulk removal in plant environments. With 10 000 –12500 L stainless steel tanks and dual-cyclone filters, these units effectively suction hazardous or abrasive residues. The IMPI unit pairs industrial-strength jetting with powerful vacuum suction in a single, highly versatile vehicle. Built on a chassis of the customer’s choice and
carrying a tilting 12 500 L 304 stainless steel tank, these units offer hydraulically driven jet pumps (295 L/min @ 135 bar) and a vacuum pump capable of 1 850 m³/ hr suction. “At Werner Pumps, we pride ourselves on offering 100% locally manufactured, high quality, low maintenance and long-life equipment solutions with maintenance plans attached that allow maintenance to be done conveniently onsite,” says Jolly. n
