Cutter Pumps SFC420...2320

Cutter Pumps
The cutter pumps of the series SFC are capable of cutting aluminium chips and similar materials and pumping of these materials along with the coolant fluid. An agitator located at the pump suction helps to break up and separate any large bundles of chips or birds nests which reach the pump suction.
The specially made cutting unit (>60HRC) is cuting  chips and the above located semi-open impeller allows with its large clearances to pump the particles along with the coolant fluid from the machine back to the filter. The SFC pumps are capable of handling chip to coolant ratios of up to 1.5% by weight.
The SFC pumps are equipped with the user-friendly 45 degree flange connection which allows for either vertical or horizontal pipe connection and the connection of a pressure gauge with G 1/4.
For more information see lifting pumps features SFC/SBC within the technical information section.
