Progressive Cavity Pumps

The progressive cavity pump is one of the most widely utilized types of machinery across biogas plants, as well as in the pharmaceutical, food and beverage, petrochemical, and oil industries. These pumps are renowned for their simple yet robust design, which ensures exceptional reliability.
The pump itself comprises only one moving part—the rotor—and a stator, which is typically made of wear-resistant materials such as rubber or elastomers. The specific material composition of the stator is selected based on the requirements of the application.
The pump's design creates multiple cavities between the rotor and stator. As the rotor rotates, one cavity opens while another closes, generating a positive displacement effect. This unique design offers several significant advantages that make progressive cavity pumps a preferred choice:

  • Low wear
  • High operational efficiency
  • Reliable performance with highly viscous fluids
  • Effective handling of foreign materials in pumped fluid
  • Low rotational speeds combined with a durable construction

This combination of features makes progressive cavity pumps highly versatile and suitable for demanding industrial applications.

One of the manufacturers we collaborate with is Pumpenfabrik Wangen GmbH—a globally recognized leader in the production of positive displacement pumps.
