Johnson Pump CM30P7-1 12V Circulation Pump, 5.3 GPM

The Johnson Pump CM30P7-1 is a heavy duty, magnetically driven circulation pump built for demanding onboard fluid-circulation duties. Compact but powerful, it is designed for circulating water or antifreeze in heating systems, or for moving cooling fresh water through a system loop. The CM30P7-1 is a normal-priming centrifugal pump, so it must be mounted where it stays flooded at all times, or be primed manually before each startup.

Construction pairs a PPA thermoplastic pump body and impeller with a stainless steel shaft for corrosion resistance in a marine environment. The pump runs on 12V power, draws up to 27W, and moves up to 5.3 GPM against a maximum system pressure of 2.5 bar (36 psi). It accepts either 5/8 inch or 3/4 inch hose at the port, and is rated to operate across a liquid temperature range of -40 F to 212 F. The pump can run dry for up to 30 minutes maximum without damage, and mounts using a separate universal bracket suited to flat surfaces.

Compact overall dimensions of 6.97 inches long, 2.68 inches wide, and 3.35 inches high allow the CM30P7-1 to fit into tight engine room or utility spaces where a dependable, higher-output circulation pump is needed.
