CM Magnetically Driven Circulation Pumps with Brushless Motor
These heavy-duty, magnetically driven, seal-less circulation pumps feature brushless motors designed for continuous use. They are ideal for circulation tasks in heating and cooling systems for buses, trains, boats and similar applications. They also function well as general-purpose pumps wherever self-priming is not essential.

Johnson Pump CM Series Pumps are normal-priming centrifugal pumps and should be mounted in a way that ensures they are always flooded or else 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, 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.
