Screw pump is a kind of volumetric rotor pump, which depends on the volume change of the sealing cavity formed by screw rod and liner to inhale and discharge liquid. Screw pump is characterized by stable flow, small pressure pulsation, self-absorption capacity, low noise, high efficiency, long life and reliable operation. Its outstanding advantage is that it can transport high viscosity medium without forming whirlpool when transporting medium。
Screw pump includes single screw pump and double screw pump, single screw pump usually as feeding pump for filter press machine. with a lift of 60~120 meters, respectively for common pressure and high pressure models.
Screw pump widely used for industrial sewage, domestic sewage, different kinds of waste waters, because it can reaches food grade, also can feed cooking oil, bee, sugar sauce, and so on.
