Compact but powerful, it is designed for circulation duties such as moving water or antifreeze through heating systems, or circulating cooling fresh water in closed-loop systems. As a normal-priming centrifugal pump, the CM10P7-1 must be mounted so it is always flooded, or primed before switching on, for reliable operation.\u003c\/p\u003e\u003cp\u003eConstruction pairs a PPA thermoplastic pump body and impeller with a stainless steel shaft for corrosion resistance and long service life in wet, marine environments. The pump runs on 12 volts, draws 14 watts of input power, and delivers 4 GPM of flow 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 mounts to a separate universal bracket for flat surfaces, keeping installation flexible across different equipment layouts. The pump tolerates liquid temperatures from -40 degrees F up to 212 degrees F, and can run dry for up to 30 minutes without damage, adding a margin of safety if the system briefly loses prime.\u003c\/p\u003e\u003cp\u003eCompact dimensions of 6.97 inches long, 2.68 inches wide, and 3.35 inches high let the CM10P7-1 fit into tight equipment spaces typical of marine heating and cooling installations.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Johnson Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 10-24501-03\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e CM10P7-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 Volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Size:\u003c\/strong\u003e 5\/8 inch or 3\/4 inch hose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e 4 GPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Power:\u003c\/strong\u003e 14 Watts Max\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Liquid Temperature:\u003c\/strong\u003e -40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Liquid Temperature:\u003c\/strong\u003e 212 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDry Running:\u003c\/strong\u003e 30 minutes max\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Pressure:\u003c\/strong\u003e 2.5 bar max (36 psi)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 6.97 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 2.68 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 3.35 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePump Body Material:\u003c\/strong\u003e PPA, Thermoplastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Material:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpeller Material:\u003c\/strong\u003e PPA, Thermoplastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Separate universal bracket for flat surfaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 7330717000585\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThis is a universal-mount circulation pump for water and antifreeze heating\/cooling circuits;
