Description

The Johnson CM30 is a magnetically driven circulation pump with a brushed motor designed for continuous use. This heavy-duty pump is compact and powerful, making it ideal for circulating water or antifreeze in automotive, marine, and RV heating systems, as well as for fresh water cooling. It is a normal-priming centrifugal pump that requires a flooded mounting position or priming before operation and should not be used with soiled water containing hard particles.
