screw pump stator

The stator of a screw pump is one of the main components of the pump. It is a stationary element located inside the screw pump and works in conjunction with the rotating screw (rotor) to form the pump cavity.

The stator is typically made of elastic materials such as rubber or polymers. It has a special helical shape that matches the cam shape of the screw. When the screw rotates, the helical shape of the stator creates sealing gaps with the screw's cam, allowing for the suction and discharge of fluids.

The primary function of the stator is to provide sealing and pumping action in the screw pump. The sealing gaps between the stator and the screw effectively propel the liquid or semi-solid material, moving it along the length of the screw and generating continuous flow within the pump cavity.

The stator undergoes wear and tear during operation, particularly in the contact surface with the screw. Therefore, regular inspection and replacement of the stator are important steps in maintaining the performance and efficiency of the screw pump.

The stator is a critical component of a screw pump, playing a key role in sealing and propelling fluids. Proper maintenance and replacement of the stator ensure reliable operation and longevity of the screw pump.
