CAVITY STYLE TECHNOLOGY The newly improved 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. Micropump’s GJR Series pumps use leading materials and design processes to deliver exceptional pump performance and reliability in challenging fluid applications. The GJR Series is your severe duty pump of choice. Designed specifically to deliver long-life performance in aggressive environments. UNBEATABLE PERFORMANCE Solid carbide gear material withstands even higher differential pressures. PREMIUM MATERIALS 316 Stainless Steel with ultimate durability coating. MAGNETIC DRIVE PUMP
