stator progressive cavity pump

A stator progressive cavity pump, also known as a Moineau or eccentric screw pump, is a type of positive displacement pump that is commonly used in various industries, such as oil and gas, mining, and chemical processing. The key features of a stator progressive cavity pump are:

1. 1. Rotor and Stator:

      • • The pump consists of a helical-shaped rotor that rotates within a double-helix stator.
      • • The rotor and stator form a series of sealed cavities that progress along the length of the pump as the rotor turns.

1. 1. Eccentric Motion:

      • • The rotor is offset (eccentric) from the center of the stator, creating a moving seal between the two components.
      • • This eccentric motion allows the pump to create a series of cavities that move from the inlet to the outlet, effectively transporting the fluid.

1. 1. Positive Displacement:

      • • As the rotor turns, the fluid is trapped in the cavities and transported through the pump, resulting in a continuous and relatively pulsation-free flow.
      • • This makes stator progressive cavity pumps well-suited for handling viscous, abrasive, or shear-sensitive fluids.

1. 1. Versatility:

      • • Stator progressive cavity pumps can handle a wide range of fluid types, including liquids, slurries, and even some gases.
      • • They are commonly used for applications such as oil and gas production, wastewater treatment, food processing, and pharmaceutical manufacturing.

1. 1. Efficiency and Durability:

      • • The simple and robust design of stator progressive cavity pumps allows for efficient operation and long service life.
      • • The use of a single-piece rotor and a replaceable stator component makes maintenance and repair relatively straightforward.

Overall, the stator progressive cavity pump is a versatile and reliable positive displacement pump that is well-suited for handling a variety of fluids in numerous industrial applications.
