Designed for the circulation and transfer of fluids, GRI’s Integrity Series Magnetic Drive Circulator 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 variable speed motor, the magnetically coupled centrifugal 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.

GRI’s DC powered variable speed pumps are ideal for a multiple of OEM applications where a small footprint is desired and high performance is expected.
