Macerator pump gets patent

Jun 24, 2017 by Triton Staff

New Jersey-based Raritan Engineering has received a U.S. patent for its 53101 Macerator Pump with Waste Valve, which makes servicing of marine sanitation pumps cleaner and faster.

The 53101 model features a nitrile rubber impeller, a spring-loaded Viton motor shaft seal, and can discharge left, right or from the top.

The Waste Valve isolates the impeller housing from the holding tank discharge port. To service the pump, turn the waste valve lever to the closed position and separate the quick disconnect assembly. A video is at

The pump has a list price of $290. For more information, visit
