Johnson Pump CM30P7-1 12V Circulation Pump, 5/8-3/4 Inch Port, 5.3 GPM, Part 10-24488-03

The Johnson Pump CM30P7-1 (part number 10-24488-03) is a heavy duty, magnetically driven circulation pump built for continuous-duty water and antifreeze circulation aboard boats. It is a compact but powerful unit sized for demanding circulation tasks such as moving water or antifreeze through heating systems, or circulating cooling fresh water. As a normal-priming centrifugal pump, the CM30P7-1 must be mounted so it stays flooded at all times, or it should be primed before switching on.

Construction pairs a PPA thermoplastic pump body with a PPA thermoplastic impeller and a stainless steel shaft, giving the pump corrosion resistance suited to marine environments. It ships with a flexible power cord and mounts using a separate universal bracket for flat surfaces. The pump draws 12 volts DC and up to 27 watts of input power, moving up to 5.3 gallons per minute against a maximum system pressure of 2.5 bar (36 psi). It connects to either 5/8 inch or 3/4 inch hose and is rated for dry running up to 30 minutes maximum. Liquid temperature range runs from -40 degrees F to 212 degrees F maximum.
