Ultra-Quiet Circulation Pumps for Water

Instead of a fan-cooled motor, these pumps have an integrated motor that's cooled by the liquid being pumped for virtually silent operation and a long service life. Also known as canned motor pumps, they're commonly used in chiller systems and aquariums. They can be mounted horizontally or vertically, but the motor must be below the impeller. Pumps are gravity fed and require an elevated liquid source to fully fill the pump before turning on. Do not run dry or use with solids.

Note: If flow control is needed, place valves or reducers on the discharge side; never restrict the inlet of a pump with a valve or reducer.
