Moyno”s 500 Grinder Pumps feature compact, lightweight designs that combine a solids reduction unit with a progressing-cavity pump. The pumps are a good fit for marine septic systems, environmental cleanup, marine oil spills, industrial wastes, and raw sewage transfer. The replaceable carbide tips on the cast iron cutter disc rotate against a stationary, hardened tool-steel cutter ring. Stringy fibers and other debris are reduced to regular particle sizes, which prevent ragging and blockages in downstream process equipment. The pumps include a molded, elastomeric wobble stator that increases the compression fit with the rotor for volumetric efficiency. The pumps support flowrates to 15 GPM and discharge pressures to 100 PSI. The pumps feature prefabricated, fully sealed ball bearings, carbon/ceramic mechanical seal, NPT suction and discharge ports, ANSI compatible tank mounting flange.
