Magnetic Drive Pumps

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. For a complete magnetic drive overview, click Magnetic Drive Overview under Product Resources.

Pump Specifications:
Flow Rates - Range to 35 gpm (132 lpm)
Max. Discharge Head - Range to 53 feet (16 m)
Max. Fluid Temperature - Up to 250 F (121 C)
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.

Materials in Contact with Solution: See individual pump series.

Selection Procedure: Determine the flow and discharge head requirements for your system. The performance curves on this page provide the flow rates for each magnetic drive pump series. The performance curve characteristics of a pump model may not meet the exact requirements of your application. It may be necessary to throttle the discharge of a pump with more flow or head capacity to fine tune the performance.

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

Typical OEM applications include film processors, Laser and x-ray cooling systems, medical, scientific, laboratory, solar thermal heating and cooling applications, and silver recovery equipment. Magnetic drive centrifugal pumps must be used where flooded suction conditions exist.
