Screw pumps, particularly progressive cavity pumps, are widely used in various industries for their ability to handle viscous, abrasive, and shear-sensitive fluids. The stator, a critical component of these pumps, is typically made of an elastomeric material that forms a sealed cavity with the rotating rotor. Over time, the stator undergoes wear due to mechanical stress, chemical degradation, and thermal effects. Recognizing the signs of a worn stator and knowing how to address them is essential for maintaining pump efficiency and preventing costly downtime.

Screw pumps are widely used in various industries due to their efficiency, reliability, and ability to handle viscous fluids. However, to maximize their performance and lifespan, engineers must equip them with the right accessories. These accessories enhance functionality, improve safety, and ensure smooth operation in demanding conditions.

Screw pumps are widely used in various industries due to their ability to handle viscous, abrasive, and high-pressure fluids efficiently. However, in harsh environments—such as those with extreme temperatures, corrosive chemicals, high abrasion, or explosive atmospheres—standard screw pumps may require specialized accessories to ensure reliability, longevity, and safety.
