Our organization is widely preferred in exporting a wide range of screw pump in beijing, china. The pump is an ideal pump for feeding to decanter centrifuge without shearing or agitating the drilling mud. The main parts are screw shaft (rotor) and screw shaft bushing (stator). Because of the special geometry shape of the two parts, they form pressurize capacity separately. The fluids flow along with the shaft, inner flow speed is slow, capacity remains, pressure is steady, so it will not generate vortex and agitating. Key features ?compared with the centrifugal pump, screw pump does not need to install the valve, the flow is stable linear flow. ?compared with the pneumatic diaphragm pump, screw pump can transport a variety of mixed impurities containing gas/ solid particles/ fibers of the media, as well as a variety of corrosive substances. ?compared with the gear pump, screw pump can transport high viscosity material. ?compared with the plunger pump, diaphragm pump and gear pump, screw pump can be used for chemical filling and metering.
