The Moyno™ 2000 HS system can pump filter cake further distances with higher volumetric efficiencies than any other progressing cavity pump, the company says. Its twin-screw feeder supplies a constant, pressurized feed rate to the pump resulting in a 100 percent pump cavity fill rate. The Moyno 2000 HS System features an integral hopper with a twin-screw auger feeder and specially designed progressing cavity pump that efficiently handles dewatered municipal sludge to over 50 percent solids. The enhanced design of the Ultra-Feed™ pump rotor provides superior volumetric efficiency. The Moyno 2000 HS System combines high pump efficiency with low discharge pressure to provide unmatched performance in high solids sludge cake transfer. Compared to hydraulically driven, piston ram type pumps and open conveyors, the Moyno 2000 HS System requires lower capital investment, lower operating costs and less maintenance, according to Moyno. For application versatility, the Moyno 2000 HS System offers varying twin screw feeder and hopper lengths to match wide feed areas from centrifuges and 1- through 3-meter length belt filter presses. The twin screw feeder and the hopper length can be readily modified without changing the pump arrangement.
