Integrity Series Brushless DC Circulation Pumps

Brushless DC Circulation Pumps

Designed for the circulation and transfer of fluids, GRI’s Integrity Series Pumps offer a flexible, safe and robust solution to moving fluid in critical high-tech OEM applications.

Equipped with an integrated brushless DC variable speed motor, with ranges of 12 to 48 volts, these seal-less, motor integrated centrifugal pumps incorporate the components into a compact, lightweight design. Fewer parts promote long life, quiet operation, and low power consumption.

Unlike its competition, GRI manufactures the pump’s brushless DC motors, along with the majority of the components, in-house. Our vertical integration provides the ability to customize a pump’s motor to an OEM’s specific flow and pressure performance requirements.

Integrity Series Pumps are designed and manufactured specifically for OEM customization. If you don’t immediately find a pump that meets your exact requirements, our dedicated Pump Team is ready to work with you in developing a solution specific to your application.
