Screw pumps Single, twin and triple screw pumps (positive displacement pumps)for application such as loading, unloading, transfer, dosing, draining, re-circulation, feeding to spray driers, filter presses, centrifuges, digester, evaporators etc.
The signle screw pump is an ideal pump for feeding to the decanter centrifuge without shearing or agitating the drilling mud. The main parts are screw shaft (rotor) and screw shaft bushing. Because the special geometry shape of the two parts, they form pressurize capacity separately.
