Johnson CM10 Circulation Pump

These heavy-duty, magnetically driven, seal-less circulation pumps feature brushed motors designed for continuous use. Compact and powerful, they are ideal for a variety of circulation applications, including the circulation of water or antifreeze in heating systems for cars, boats and recreational vehicles; the circulation of fresh water for cooling in vehicles; and general-purpose circulation where self-priming is not required.

Johnson Pump CM Series Pumps are normal-priming centrifugal pumps and should be mounted in a way that ensures they are always flooded, or they must be primed before being switched on. These pumps should not be used with soiled water containing hard particles.
