The goal of a grinder pump is to process solids, making them small enough to pass through the pump and discharge line without plugging. While most grinder pumps effectively compress the solids as they pass through the pump, permitting compressed stringy solids to reside in the pump when the unit is turned off, the HOMA grinder takes a different approach. Solids are processed with a dual-action cutter operating outside of the pump, below the impeller. The unique hardened cutter system is manufactured in stainless steel alloyed with cobalt, vanadium, and molybdenum. Both stationary and rotational cutters are hardened to a minimum of 55 Rockwell C and provide 13,800 cuts per minute.
