Johnson Pump CM90 17.2 GPM 12V Circulation Pump

The Johnson Pump CM90 17.2 GPM 12V Circulation Pump is a compact magnetically driven centrifugal pump designed for continuous circulation of compatible fresh water, salt water, and water-glycol mixtures. Its high-flow, low-current design suits heating, cooling, and circulation systems where efficient fluid movement is needed without a bulky conventional pump package.

Magnetic drive separates the motor from the pumping chamber without a conventional shaft seal, while the glass-fiber-reinforced body gives durable fluid handling. The motor is replaceable, and the design is rated for extended service life when operated within the specified pressure, temperature, and fluid-concentration limits.

Confirm fluid compatibility, glycol concentration, system pressure, electrical protection, hose connections, mounting position, and operating temperature before installation. Avoid restrictions at the inlet, protect the pump from unsupported plumbing loads, and verify circulation and leak-free connections after filling and bleeding the system.
