Johnson Pump Macerator Pump

Johnson Pump's Macerator Pump grinds toilet waste, shredding it before it is pumped into or out from the holding tank. It utilizes a high speed rotary cutter to shred waste efficiently. The pump consists of a brass shredder, nitrile impeller, and stainless steel shaft for corrosion and chemical resistance.

Johnson pumps are designed to allow direct interchange with other macerators for easy installation. Empties a 30 gallon holding tank in about 3 minutes. Suitable for bowl or holding tank discharge.

Good product


Used in RV application. No suction lift issue as RV is gravity feed to pump. Pump is mounted to plastic bin floor with supplied grommets. Louder than I expected but I did not do any isolation mount improvement. Attention is required when running as the suction can get ahead of the gravity flow as the tank gets close to empty. The only additional parts needed were plumbing pieces and a switch. Noteworthy is that the pump motor does not heat up or even warm up, a sign of proper sizing and bearings. A much cheaper way and just as easy as buying "kit" from camping suppliers.
