Johnson Pump 102448803 CM Series Mag Drive Circulating Pump w/Cord, 5.3 GPM, 12V

Magnetically driven centrifugal pump is designed for continuous operation and can move up to 60% glycol and water mixture. These pumps have a small footprint and can run dry for up to 30 min. Offering consistent flow rates with very low electrical consumption, the compact but heavy-duty construction is both waterproof and dustproof. Meets the demands for heating and cooling systems on boats, RVs and auto applications and is a direct replacement for OEM intercooler circulation pumps.
