Description:

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. 

Features:

1. Good self-priming performance, the suction range can reach 6 meters of water column;
2. Can transport liquids containing solid particles, the solid content can reach 40% (volume ratio), And the solid content can reach up to 60% or higher when the solid contained in the medium is powder particles.
3. Can transport very viscous non-Newtonian liquids;
4. Smooth and undisturbed during transportation, the liquid volume is uniform. There is no turbulence, stirring, or pulsation;
5. The flow rate of the pump is approximately proportional to the speed, and the flow rate is easy to adjust;
6. The flow rate is uniform and the pump pressure is small;
7. Simple structure, easy to install, disassemble, and maintain.
