Product Overview

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.

Specifications

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.

Features

  • Corrosion resistant
  • Hydraulically efficient
  • No shaft seals
  • Low current draw and heat rise

The chart below is just a general overview of the magnetic drive pumps offered. GRI specializes in the custom design and manufacturing of fluid pumps for the OEM market.

There are many variables that must be considered when specifying a magnetic drive pump for an OEM application. At first glance you may not find a pump that meets your exact requirements. GRI recommends that you contact our Technical Sales Staff to discuss your project so that the right pump can be specified. Many times we will customize an existing pump to meet your needs or design a new pump according to your system’s exact specifications.
