Engineered dewatering for emerging markets

Jonathan Höll, Xylem’s African product manager for dewatering, talks about the company’s dewatering pump range, most notably the Godwin BD 150 Dri-Prime ® Pump, which has been re-engineered for mining, industrial and utility dewatering in emerging markets.

watering demands in Africa. “The diesel driven portable version is powered by a 3 or 6-cylinder Kirloskar en gine from India, but electric motor and other engine options are also available. The Venturi prime version (BD150T) can offer flow rates of up to 500 m 3 /hr or heads of up to 42 m,” he says. “They are also very flexible. The impellers can be very easily changed from a two blade impeller designed to handle slurries and solid particles, to a more efficient three blade ver sion designed for clearwater applications,” Höll tells MCA . These features make the Godwin BD150 ideal for maintaining slimes dams, mine water ponds and wastewater dams and all kinds, or for dewatering mine pits or quarries. “They can be trailer mounted or fitted onto skids for easy transportation. We can put them onto floating pontoons for dredging and we can even supply electric-powered versions for more permanent dewatering requirements,” he says, adding that Xylem is able to offer a full dewatering service for clients needing a

re-engineered to suit the rigours of emerging markets. “These pumps have 150 mm suction and discharge pipe diameters and are designed to deliver steady and con tinuous flow. “They can handle solid particles of up to 75 mm and slurry densities of up to 1.2 SG,” he says, making this pump suitable for decanting dirty water with suspended solids. “The Godwin BD150 Dri-Prime ® Pump is our regions newly developed champion,” Höll continues. The whole system has been redesigned so that it can deliver efficiently, cost effectively and, in our rugged markets, much more reliably,” he notes. Designed as an on shore pump, the re designed BD150 includes fully automatic dry priming with 8.5 m of suction lift. Two self-priming options are available, including a vacuum pump option or a venturi priming sys tem driven off an air compressor. Innovative, simple and robust construction from corro sion resistant materials and abrasion resistant silicon carbide faces ensure reliability, while ease of handling and simplified servicing makes these units ideal for the rigorous de

A s Xylem’s product manager for de watering, Jonathan Höll is respon sible for the full dewatering range, from submersibles and wastewater slurry pumps to diesel driven self-priming portable pumps capable of high head or high flow applications for dewatering or dredg ing. “We can offer solutions from numerous pump brands, Xylem Flygt submersibles and slimline Flygt pumps for general dewatering; and the Godwin basic dewatering (BD-series) portable self-priming pumps, to name but a few,” Höll tells MCA . “The range of dewatering slurry pumps goes up to 70 kW on standard units, but we can also offer much larger ones based on the 5570-series that can tackle duties of up to 215 kW,” he adds. Turning attention to the new Godwin BD150, he says this pump has recently been completely
