Question by: Joyce M on Dec 22, 2025, 7:41 PM
what all industries is this vane pump built for? trying to figure out if it fits our setup before we pull the trigger on it
Answer by: Customer Support on Dec 24, 2025, 3:12 PM
Cast iron construction and a flow rate just under 235 liters per minute put this pump in a solid position for demanding work. Industries it covers include plastics machinery, press machines, die casting, machine tools, test equipment, primary metals, pulp and paper, wood processing, oil and gas, marine, and general industrial use. That's a pretty wide range, so unless your application falls well outside those categories, it's likely a fit.
