Servicing a macerator pump will make the most seasoned boat owner turn green. Raritan Engineering's revolutionary 53101 Macerator Pump with Waste Valve makes the job a whole lot easier and far less messy. The pump disconnects from its own gate valve housing, keeping the waste in the discharge tube for minimal spillage and odor.
Unlike problematic external ball valves that require space to operate and failure-prone clamps, the compact Raritan Waste Valve Assembly has an integrated valve. With molded-in open and shut indicators on the housing, a turn of the hex head lever closes off the waste tube. A quick disconnect then allows the macerator to be removed from the assembly. The intake plumbing connection is 1-1/2" FNPT with an included 1-1/2" barb fitting; the outlet is a 3/4" MNPT fitting. A video is at bit.ly/RaritanMacerator.
The Raritan Macerator Pump is built to ISO 8846 standards for a long service life. The 12 or 24V DC motor is ignition protected and completely encased in epoxy. It has a spring-loaded Viton shaft seal and stainless steel fasteners. The heavy-duty, dual-cut chopper blades and proprietary nitrile rubber impeller ensure low maintenance. The powerful pump has a free flow rate of 11 gpm and 6.4 gpm with a 20' head.
To help protect and maintain the Macerator Pump, Raritan offers the optional Smart Macerator Control (SMC). It monitors the motor for priming failure, dry running and power surges—all of which trigger an automatic shut down feature. The unit manually resets quickly, without need to cut the power source. It can also automatically regularly move the impeller to avoid binding.
At only 11" L x 7" W x 5" H, Raritan's patented 53101 Macerator Pump with Waste Valve fits into the tightest of spaces. The 12V DC version lists for $345; the 24V version is $370.75. They come with a one-year warranty.
Since 1956, generations of boatbuilders and owners have relied on Raritan Engineering's quality products. Renowned for its complete range of marine sanitation equipment, it also manufactures ice makers, water heaters and other innovative boating accessories.
