What is a single screw pump

Single screw pump is a positive displacement pump, relying on the interference between the eccentric movement of the rotor and the fixed stator, the formation of a non-communicating sealing cavity, through the rotation of the rotor in the stator, the sealing cavity along the axial direction from the pump inlet end to the outlet end, so that the media in the sealing cavity to achieve continuous transmission process.

Features:

1, self-priming ability is good, with water as the medium, the suction height can reach 3-5 meters.

2, can transport liquid containing solid particles, the content of solids can be up to 40% (volume ratio), when the medium contains solids for powder particles, up to 60% or higher.

3, can transport a variety of different viscosity media, viscosity up to 1000000CP.

4, can transport a variety of temperature media, temperature range from -20℃-+180℃.

5, pump flow and speed are approximately proportional, flow adjustment is convenient, can also be used as a metering pump, metering accuracy up to ±1%.

6, the transmission is stable without agitation, uniform liquid amount, small vibration, small noise.

7, high pump efficiency, volumetric efficiency up to 90%, mechanical efficiency up to 80%.

8, simple structure, installation and disassembly, easy maintenance.

Application field:

The structure and characteristics of the single screw pump determine that it is most suitable for transporting a variety of complex media containing solid particles, viscous, corrosive, shear sensitive, containing gas and fiber, and a variety of harsh conditions at different temperatures.
