Integrated Brushless DC Magnetic Drive Pumps

Product Overview



Designed for the circulation and transfer of fluids, GRI’s Integrity Series Pumps offer a flexible and robust solution to OEM applications.  

Constructed with a proprietary blend of PPS, the INTG8 is compatible with a wide variety of fluids. 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 brushless DC variable speed motor, with voltage ranges from 12-24, 36 and 48 volts, these sealless, motor integrated centrifugal pumps incorporate the components into a compact, lightweight design. Fewer parts promote long life, quiet operation, and low power consumption.

The Integrity Series 8, with its small footprint and weighing in at approximately 3.5 pounds, offers a powerful performance with a flow range from 2 gallons per minute (or 7.50 liters) up to approximately 39.0 gallons per minute (or 145.0 liters).

One will realize the advantages of the Integrity Series 8 when OEM performance requirements are 10 gallons per minute and above. Keep in mind that you will always get the most efficient performance and potentially longer pump life by running in the middle of the performance curve.  

Available OEM options include a variety of suction and discharge port configurations and control options to best fit an OEMs application. The supply voltage can directly control the pump performance. Performance can also be controlled by an available analog 0-5 volt DC input as well as a PWM digital signal input. Additionally, a tachometer option is available to measure pump speed. For advanced and high-tech applications requiring customized control, CAN-bus is also available.

GRI collaborates with OEM engineers who are unable to fulfill their unique pump specifications with an off-the-shelf solution and require a custom-engineered pump specific to their application.

Integrity Series Maximum Fluid Rating Chart

Various factors influence the recommended maximum temperature rating. These factors play a role in determining the pump’s life and applied warranties. In some applications, a higher maximum fluid temperature rating may be warranted.

  • Factors influencing maximum temperature rating include, but are not limited to:
  • Starting temperature of fluid in system
  • Ambient Temperature
  • Required performance, application’s specifications
  • Run time
