The stator of the progressive cavity pump is one of the important main parts of progressive cavity pump, also known as the progressive cavity pump bushing;
                                 
The stator is a stationary component of a progressive cavity pump that works with the rotor to move fluids.
                                 
Function: It creates sealed cavities with the rotor, allowing fluid to be trapped and transported smoothly.
                                 
Materials: Typically made from durable elastomers (like NBR, EPDM, FKM) or rigid materials (like metal and PTFE) for specific environments.
                                 
Design: The stator maintains consistent cavity shapes, ensuring a pulse-free flow, especially for viscous fluids.
                                 
Durability: Subject to wear, especially with abrasive fluids; choosing the right material is crucial for longevity.
