Seachoice NMMP1-120-01 12V Sealed Macerator Pump 10 GPM Marine Waste Pump

The Seachoice NMMP1-120-01 is a fully sealed 12V DC macerator pump engineered for reliable waste removal aboard boats and recreational vehicles. Designed to handle the demands of marine sanitation systems, this pump features a sealed motor that resists both internal and external corrosion, making it ideal for the harsh marine environment.

A high-speed rotary chopper blade shreds solid waste before it is pumped out through the discharge hose, preventing clogs and ensuring smooth, efficient evacuation. The pump connects directly to a toilet bowl discharge outlet or holding tank, offering flexible installation options. Its self-priming capability allows it to draw fluid from up to 5 feet away, and it can empty a typical 30-gallon holding tank in under 3 minutes.
