Product Announcement from GRI Pumps (Gorman-Rupp Industries)

OEM High Speed Magnetic Drive Pump-Image

New for Gorman-Rupp Industries is the High-Speed Mag-Drive centrifugal pump. The GRI High-Speed MDII has a ceramic thrust washer that improves the life over previous Mag-Drive pumps. A high RPM brushless DC motor enables the pump to reach pressures of 24 psi. Click here to learn more…

 Magnetic drive centrifugal pump operation is similar to a standard centrifugal pump except the motor shaft seal is eliminated. Instead, magnetic drive pumps are designed to isolate the wet end of the hydraulic circuit from the motor by driving an impeller and magnet assembly with a radial or axial drive magnet assembly attached to the motor shaft. Motor torque is transmitted by the drive magnet through a plastic housing that separates the driven impeller magnet from the fluid being pumped. Leaks caused by shaft seal failure are eliminated. The end result is a more efficient seal-less centrifugal pump that will not leak and is capable of achieving up to 50 thousand hours of continuous duty operation.

The impeller shaft and bearing system features an excellent combination of inert materials of construction to handle the most aggressive of chemicals and cooling passages designed to use the pumped liquid as a lubricating coolant. GRI uses ceramic shafts with either Teflon® or ceramic thrust bearings as standard materials for each magnetic drive pump line. These robust features add tremendously to the chemical compatibility and overall life of the pump to make it virtually maintenance free.

Impellers and pump bodies are designed to produce efficient flow and head characteristics required in today's applications. The hydraulic designs, coupled with motors specifically designed for the pump end, means less power consumption for the work performed.
