Combining a solids reduction unit with a progressing cavity pump, Moyno 500 grinder pumps have flow rates to 15 gpm and discharge pressures to 100psi. Replaceable carbide tips on the cast iron cutter disc rotate against a stationary, hardened tool-steel cutter ring to reduce stringy fibers and other debris to regular particle sizes. A molded, elastomeric wobble stator increases the compression fit with the rotor. The pumps also feature a carbon/ceramic mechanical seal, NPT suction and discharge ports, and an ANSI-compatible tank mounting flange.
