Screw Centrifugal Pump impeller combines the properties of a screw pump with those of a centrifugal pump. The low liquid velocity in the pump results in the relative low shear force. This makes the Centrifugal Screw Pump suitable for liquids which have to be handled carefully and without too much motion and turbulence, in order to avoid emulsification. Mavi Deniz Screw Centrifugal Pump is ideal for pumping high viscosity liquids such as crude oils, latex, molasses, and refinery wastes using a positive displacement screw. When pumping lighter materials, the impeller acts as a centrifugal type providing high capacity. Screw Centrifugal Pump uses for oil skimmers and cargo pumping.
