macerator pump

Nov 27, 2018

The realization that a macerator pump needs servicing leaves many boat owners sighing with despair. It’s a seriously nasty job. Even if a technician does the dirty work, it’ll take days to get rid of the odor. 

With Raritan Engineering’s patented 53101 Macerator Pump with Waste Valve, it’s fast and easy to disconnect the pump from the holding tank discharge tube, with minimal, if any, spillage.

Raritan’s Macerator Pump has few rivals. Available in 12 or 24V DC, it’s built for a long, reliable service life. Fully encased in epoxy, its motor has a spring-loaded shaft seal and its unique nitrile rubber impeller is tested and proven to run dry three times longer than the competition. Heavy duty, dual-cut steel chopper blades ensure complete waste maceration.

Eliminating the need for an external ball valve, Raritan’s Waste Valve isolates the impeller from the holding tank discharge port. It has a 1-1/2″ barbed inlet and 3/4″ MNPT threaded outlet. A video is at

With the optional Smart Macerator Control (SMC), the 53101 Macerator Pump with Waste Valve is almost maintenance-free. It continually monitors the pump motor to protect against priming failure and dry running. With power to the SMC, it will move the impeller periodically to avoid binding. This is especially helpful to boats that aren’t used regularly.
