CM Magnetically Driven Circulation Pumps with Brush Motor

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.

Limited 2-Year Warranty

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.

CAUTION: Do not pump gasoline, solvents, thinners, or highly concentrated or organic acids. If corrosive fluids must be handled, pump life will be prolonged by flushing with water after each use or at the end of each work day.
