A space-saving and very efficient method of feeding material produced during machining is pumping via piping systems. Thanks to its outstanding ability to pump liquids with a very high solids content without clogging, even swarf is possible without a problem, the Hidrostal Screw Centrifugal Pump is ideally suited for this task. Due to the high hydraulic efficiency, the energy consumption and thus the operating costs are significantly lower than with systems such as conveyor belts.
