Magnetic Drive Circulation Pumps

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

Designed for the circulation and transfer of fluids, GRI’s Integrity Series Magnetic Drive Circulation Pumps offer a flexible and robust pumping solution to OEM fluid circulation applications. By manufacturing the motors and the majority of the pump’s components in-house, GRI has the flexibility to precisely configure an Integrity Series pump to meet an OEM’s specific flow and pressure requirements.

Equipped with an integrated 9 to 24 volt brushless DC motor, the magnetically driven pumps incorporate the components into a compact, lightweight design, eliminating motor bearings and leaving the impeller assembly as the only moving part. Fewer parts promote long life, quiet operation, and low power consumption.
