Integrity Series Brushless DC Circulation Pumps

Brushless DC Circulation Pumps

Tuned for Performance, Stability, and Longevity...

GRI's Integrity Series® Pumps are engineered to deliver reliable, high-performance fluid circulation for today's most demanding OEM applications. Designed for liquid cooling, CDU (Coolant Distribution Unit) pumps, direct-to-chip cooling, and in-rack cooling systems, these compact centrifugal pumps provide dependable performance for modern data centers, advanced electronics, and industrial thermal management equipment.

Each Integrity Series pump features an integrated brushless DC variable-speed motor, available in 12 to 48 VDC configurations, paired with GRI's proven seal-less magnetic drive technology. By integrating the motor and pump into a single compact assembly, the Integrity Series delivers exceptional hydraulic performance while minimizing footprint, reducing noise, lowering power consumption, and extending service life. It's an ideal solution for OEMs designing next-generation data center servers, AI infrastructure, and high-density liquid cooling systems where space and efficiency are critical.

As data centers continue to evolve toward higher rack densities and greater computing power, reliable coolant circulation has become essential. Whether used in a CDU, direct-to-chip cooling loop, or in-rack liquid cooling application, Integrity Series pumps are built to provide the consistent flow and pressure required to protect mission-critical equipment while maximizing thermal performance.

Unlike many pump manufacturers, GRI designs and manufactures its brushless DC motors and the majority of pump components in-house. This vertical integration allows our engineering team to customize motor performance, hydraulic characteristics, and control options to meet each OEM's specific flow, pressure, voltage, and communication requirements.

Every Integrity Series pump is designed with OEM customization in mind. If a standard configuration doesn't perfectly fit your application, GRI's engineering team will work alongside you to develop a solution optimized for your system. From data center liquid cooling and direct-to-chip cooling to industrial circulation, electronics cooling, and specialized thermal management systems, we'll help you find the right pump for your application.
