OEM Magnetic Drive Pumps

Product Announcement from GRI Pumps (A Gorman-Rupp Company)

Magnetic drive centrifugal pump operation is similar to a standard centrifugal pump except the motor shaft seal is removed resulting in the elimination of leaks caused by shaft seal failure.


Flow Rates: Range to 35 gpm (132 lpm).Max. Discharge Head: Range to 70 feet (21.3 m).

Max. Fluid Temperature: Up to 203°F (95°C). Consult GRI for higher fluid temperature needs.

Motors: All motors, except the 15651 series and 18650 series motors which use sleeve bearings, have sealed electric motor grade ball bearings, are thermally protected, class B insulated, and continuous duty rated. Most pumps available with AC or DC motors.

For proper selection of the wetted materials of construction (pump body, impeller, adapter disc, O-ring, impeller bearing) refer to the Chemical Resistance Charts.
