Working principle of single screw pump:

An independent sealing chamber is formed between the rotor and the stator of a single screw pump. When the rotor rotates in the stator, the sealing chamber formed by the combination of the stator and the rotor will move along the axis from the inlet end of the pump to the outlet end. The medium in the sealing chamber also completes the transportation from the inlet to the outlet. This is the working principle of the single screw pump.


Selection of Rubber Material for Single Screw Pump Bushing:

The bushing of single screw pump is a rubber product and a vulnerable part of single screw pump. Its choice directly affects the life of bushing. Normally, the life of bushing is 3-6 months. If the bushing is not selected properly, it may fall off from steel pipe or rubber block.

Selection of material combination for single screw pump:

Transport of different properties of media requires different combinations of materials.

Single screw pump performance:

Generally, the performance tables or characteristic curves of single screw pumps are based on the data when the water at 20 C is used as medium (the viscosity is 1cst). The flow rate and the shaft power are different for conveying different viscosity.
