The type RSR return pumping station is a compact feed station suitable for side installation on machine tools which produce small amounts of chips, particularly grinders. It can be configured as a collection station for collecting small amounts of cooling lubricant from centrifuges, conveyors and drip pans.
The cooling lubricant contaminated with sludge or chips flows through an outlet on the machine tool and into the pump back tank. An auxiliary lifting pump assists this process where required. The recirculation pump transports the chip/cooling lubricant mixture through the return pipe to the filtration system. The tangential intake has a helical channel which prevents the deposition of grinding sludge.
