Gear Pump Group 1
Fixed clearance external gear pump, suited for the low to mid range flow requirements. Designed to be readily connected to IEC metric electric motors via bespoke bell housings. Foot mounted units allow ‘long coupled’ variants and connections to other prime movers. Foot & Flange options give the opportunity for larger port sizes for viscous fluids.
