Johnson Pump CM10P7-1 12V Circulation Pump with Cord, 4 GPM, 5/8 Inch Port

The Johnson Pump CM10P7-1 is a heavy duty, magnetically driven circulation pump built for continuous-duty water and antifreeze circulation aboard boats. Compact yet powerful, it is ideal for circulating water or antifreeze in heating systems, or for moving cooling fresh water through onboard systems. As a normal-priming centrifugal pump, the CM10P7-1 must be mounted so it stays flooded at all times, or be primed manually before switching on; it is rated for up to 30 minutes of dry running.

Construction pairs a PPA thermoplastic pump body and impeller with a stainless steel shaft, an EPDM O-ring, a PSU magnet housing, and an enclosed DC permanent magnet on a ball-bearing-mounted motor designed for continuous operation. It is suitable for fresh water, salt water, and water/glycol mixtures up to 60 percent glycol. The pump runs on 12V DC power, draws 14 watts maximum, and delivers 4 GPM capacity through a 5/8 inch or 3/4 inch hose port. It ships with a flexible cord and mounts to a separate universal bracket for flat surfaces, sold apart from the pump body.
