What is a screw pump stator？



The stator is a crucial component of a screw pump, and it is responsible for creating the chambers that move the fluid through the pump. It is a stationary cylinder with an internal helical profile that matches the rotor’s screw thread. The rotor rotates inside the stator, and the screw thread forms a series of chambers that trap and move the fluid from the pump inlet to the outlet.To get more news about SEEPEX Pump Parts, you can visit hw-screwpump.com official website.

The geometry of the stator’s internal profile is critical to the pump’s performance. It should be closely matched to the rotor’s helical screw thread to minimize clearance between the two components. The clearance should be minimal to ensure that the fluid is effectively trapped and moved along the screw thread without any leakage.

The stator’s material is also essential to the pump’s performance and longevity. Stator materials should have high wear resistance, corrosion resistance, and mechanical strength. Common materials used for stator construction include rubber, elastomers, and various polymers.

The stator’s design also affects the pump’s performance. For example, some screw pumps have stators with an elongated profile, while others have a shorter profile. Longer profiles tend to generate higher pressures, while shorter profiles tend to generate higher flow rates.
Another critical factor that affects the pump’s performance is the stator’s surface finish. The surface finish should be smooth to minimize friction between the stator and rotor, which can lead to wear and reduced performance.

The stator’s size also affects the pump’s performance. Generally, larger stators generate higher pressures, while smaller stators generate higher flow rates. However, the stator size should be optimized to balance performance and efficiency.

Proper maintenance and care of the stator can ensure optimal pump performance and longevity. Regular cleaning, inspection, and replacement of worn or damaged stators can help extend the pump’s lifespan and prevent downtime.

In conclusion, screw pump stator is a critical component of a screw pump. Its geometry, material, design, surface finish, and size all affect the pump’s performance and longevity. Proper maintenance and care of the stator can ensure optimal pump performance and prevent downtime.
