Screw pumps, also known as progressive cavity pumps, are widely used in various industries due to their ability to handle viscous fluids, slurries, and even gases with minimal pulsation. Understanding the working principle of screw pumps is crucial for optimizing their performance and ensuring long-term reliability. This post will delve into the fundamental principles behind screw pumps, supported by real-world examples and data.

The selection of stator material for single screw pumps is a comprehensive process, which needs to be comprehensively considered according to the specific working environment and medium characteristics. Selecting the right stator material will help improve the performance and service life of the pump.

The stator of the G-type single screw pump is also called a rubber sleeve. The inner wall of the rubber sleeve is made of rubber material. Since the gap between the rubber sleeve and the rotor (screw) is small, the G-type screw pump is prohibited from idling and must have liquid for use. There is lubrication between the rubber sleeve and the screw shaft. During the rotation of the rotor (screw), friction will occur with the rubber sleeve. If the transported liquid contains fine hard particles, the service life of the rubber sleeve will be reduced. It is recommended to use abrasive liquids. Low speed screw pump. So to extend the service life of the rubber sleeve, you need to reduce the wear of the rubber.
