Gear Pumps - GR

BRAND: Flowserve

Capable of higher flows and pressures than GA Series pumps, GR Series pumps provide high efficiency, pulse-free pumping, even under the most challenging conditions. They are designed to handle viscous fluids across a broad spectrum of flows and pressures. The GR Series’ simple external design has only two moving parts and only one shaft seal to ensure long life and ease of maintenance.
