Product Overview: Single-rotor screw pump is a positive displacement pump, are chemical pumps, it is relying on volume changes formed by the screw and the bushing seal chamber to suction and discharge the liquid. The chemical pump divided by the number of screw single screw, double, triple and five screw. PCP is characterized by a smooth flow, pressure pulsation, self-absorption capacity, low noise, high efficiency, long life, reliable operation; and its prominent advantage is that a vortex is formed when the transmission medium is not insensitive to the medium viscosity, may transporting high-viscosity media. Shanghai-pump chemical pump Introduction: DBY electric diaphragm pump series of high-quality chemical pumps, using cycloid reducer drive chemical pump sales, driven double diaphragm reciprocated by the crank slider mechanism, the working chamber volume to achieve the change will take place alternately liquid continuous suction and discharge. Meanwhile, in recent years due to the membrane material has made breakthrough progress, greatly extend the service life of the diaphragm is, so it is more and more widely to replace part of centrifugal pumps, screw pumps to used in petrochemical, ceramics, metallurgy and other industries.
