Stainless steel single screw pump is a single screw transport pump. Its main working parts are the screw of eccentric helix (called rotor) and the screw bushing with double helical surface (called stator). Its working principle is that when the motor drives the pump shaft to rotate, on the one hand, the screw rotates around its own axis, on the other hand, it rolls along the inner surface of the bushing, thus forming the sealing chamber of the pump. With the continuous rotation of the screw, the liquid in the sealing chamber pushes forward one pitch every rotation of the screw. The liquid screw is pressed from one sealing chamber to another, and finally the pump body is extruded. Screw pump is a new type of liquid conveying machine. It has the advantages of simple structure, safe and reliable operation, convenient use and maintenance, continuous and uniform discharge, stable pressure and so on. A pump that sucks and discharges liquid by rotating screw is most suitable for sucking and discharging viscous liquid.


Key Points for Selection of Single Screw Pump

The selection of single screw pump mainly focuses on the following parameters:

Pressure determination of single screw pump:

The maximum output pressure of a single screw pump is determined by the series of bushes, i.e. the guide number of bushes (stators):

Level 1: The maximum working pressure is 0.6 MPa.

Level 2: Maximum working pressure is 1.2 MPa;

Level 4: Maximum working pressure is 2.4 MPa;

Due to the different conditions of the conveying media, the suitable stator series is selected according to the conveying pressure requirements for the medium with severe wear.


Selection of Speed of Single Screw Pump:

Because of its structural characteristics, single screw pumps are mostly used to transport liquids with high viscosity and particles, so the selection of rotational speed is very critical. For single screw pump, the selection of rotational speed is mainly based on the wearability of the medium and the medium viscosity.
