JOHNSON CM90P7-1 Circulation Pump (12V / 38mm)
CM90P Manual | CM90P Sales Flyer
The CM90 circulation pump has been developed primarily for heating and cooling applications in buses, trains and boats, but it is much more. In closed systems or wherever else self-priming is not required, the CM90 is an all-round pump that distinguishes itself for its dependability, capacity and long service life.
The CM90 pump has a magnetic drive, which means that no shaft seal is necessary, as the motor shaft does not penetrate the pump house. With no mechanical seal, longer service life is assured. Heat flanges on both the motor and the pump also increase service life as they dissipate heat from the unit, which can pump liquids efficiently at a very wide range of temperatures. The CM90 also features integral thermal overload protection and is EMC approved according to EN 55014 standards.
The CM90 magnetic driven centrifugal pump combines a high flow rate with very low electricity consumption, making it ideal for vehicular heating and cooling systems.
