Micropump : GJR Series

Magnetic Drive Gear Pump

The GJR Series is your severe duty solution. From inception, the GJR has set the standard.

Abrasive fluids, such as pigmented paints and inks or metal loaded fluids, often cause significant pump wear, impacting pumping functionality and dramatically
shortening pump life. The GJR Series pumps use leading materials and design processes to deliver exceptional pump performance and reliability in challenging fluid applications.

Featuring a cavity style design, these pumps are excellent for wide-ranging inlet and outlet operating conditions and allow for intermittently pumping in reverse.
