Screw Pumps Stator Suppliers

In a screw pump, the stator is a crucial stationary component that complements the rotor(s) in the pumping mechanism. It forms a part of the pump's internal structure, working together with the rotating screw(s) to create a sealed, moving chamber through which the fluid is displaced. The stator is typically a cylindrical or helical component made from various materials, and its design plays a vital role in the pump's efficiency and performance.

Materials Used for Screw Pump Stators

The material chosen for the stator is crucial as it impacts the pump's durability, performance, and suitability for different fluids. Common materials used for screw pump stators include:

1. Rubber

Properties: Flexible, wear-resistant, and provides desirable sealing capabilities.

Applications: Often used in applications requiring resistance to abrasion and the ability to handle viscous fluids. Rubber stators are common in progressive cavity pumps.

2. Polyurethane

Properties: Offers a good balance between flexibility and durability, with resistance to wear and chemicals.

Applications: Suitable for handling abrasive and corrosive fluids, used in various industrial and wastewater applications.

3. Elastomeric Materials

Properties: Includes various synthetic rubber compounds known for their resilience and flexibility.

Applications: Used in pumps that handle a wide range of fluid types, from corrosive to non-corrosive, and in various temperature ranges.

4. Metal Alloys

Properties: Provides high strength and durability, though less flexible than rubber or elastomers.

Applications: Used in high-pressure or high-temperature applications, such as in the oil and gas industry. Common metal alloys include stainless steel and alloy steels.

5. Composite Materials

Properties: Made from a combination of materials to achieve specific properties, such as improved wear resistance and reduced weight.

Applications: Used in specialized applications where traditional materials may not provide the required performance, such as in environmental conditions.

Considerations for Stator Material Selection

Selecting the appropriate material for a screw pump stator involves evaluating several factors:


  • Fluid Characteristics

    The corrosiveness, abrasiveness, and temperature of the fluid being pumped.

  • Operational Conditions

    The pressure, flow rate, and environmental conditions in which the pump will operate.

  • Durability and Maintenance

    The expected lifespan of the stator and the maintenance requirements associated with different materials.

  • Cost

    Balancing material costs with performance requirements and overall lifecycle costs.

Conclusion

The stator in a screw pump is essential for the efficient and reliable operation of the pump. It works in tandem with the rotor(s) to create a continuous flow of fluid and ensure smooth operation. Understanding the different materials used for screw pump stators and their properties can help in selecting the right stator for specific applications, ensuring ideal performance and longevity of the pump.

Function of the Stator

The primary function of the stator is to:


  • Form Sealed Chambers

    The stator works with the rotor(s) to form a series of sealed cavities or chambers. As the rotor(s) turn, these chambers move the fluid from the inlet to the outlet of the pump.

  • Guide Fluid Flow

    The stator provides a fixed path for the fluid, guiding it smoothly through the pump. This helps maintain a steady and consistent flow with minimal pulsation.

  • Support the Rotor(s)

    The stator maintains proper alignment and spacing for the rotating screw(s), which is essential for efficient operation and longevity of the pump.
