Ristow RV Macerator Pump 12V – 12 GPM Self-Priming RV Waste Water Pump

Overview

Meet the Ristow RV Macerator Pump 12V, a compact, self-priming solution designed for on-the-road living. With a practical 12 GPM (45 LPM) flow, it can empty a typical 150 L waste tank in minutes, while its ability to lift wastewater up to 10 ft adds flexibility for hard-to-reach dump connections.

Efficient performance you can count on

The 12V DC motor is built with copper windings for durable operation, delivering stable performance and relatively quiet running compared with many compact pumps. The unit features stainless steel four spiral blades that shred waste down to about 1/8 inch (4 mm) at maximum, helping to prevent clogs and making disposal easier.

Smart design includes run-dry protection and thermal protection to guard the motor during intermittent use. A quick-release configuration and a practical garden hose discharge port expand connection options, so you can adapt to a range of dump setups.
