INTG1 Series Product Overview

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 24 volt brushless DC motor, the INTG1 Series 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 pumps are ideal for a multiple of OEM applications where a small footprint is desired and high performance is expected. Applications and markets include, but are not limited to, chillers, coolers, medical devices, laser systems, alternative power units, hydronic heating and cooling, recreation and public transit vehicles, fuel cells, beverage dispensers, printing and imaging, and others.

There are many variables that must be considered when specifying a magnetic drive pump for an OEM application. At first glance you may not find a pump that meets your exact requirements. GRI recommends that you contact our Technical Sales Staff to discuss your project so that the right pump can be specified. Many times we will customize an existing pump to meet your needs or design a new pump according to your system’s exact specifications.

3-Wire: Three wires are required when the pump speed is controlled by a nominal 0-5v DC signal. This is done through a control panel such as a computer or other control devices that is connected to the pump via the third wire. The 0-5v signal controls the speed of the pump, not the voltage supplied to the pump. Consult factory for 2-wire lead option.
O-Ring Material: EPDM = Ethylene Propylene Diene Monomer, FKM = Fluoroelastomer.
