Range of stators for progressive cavity pumps

Stators are one of the fundamental components of helical or progressive cavity pumps. Working together with the rotor, they allow the continuous, uniform movement of fluids of different viscosity, even when they contain solid particles or have abrasive characteristics. At OSN we offer a wide range of replacement stators manufactured with high-quality elastomers, compatible with numerous helical pumps present in the food, chemical, environmental, mining, ceramic, paper and water-treatment industries.

Available materials

Stators can be manufactured in a wide variety of elastomers to guarantee maximum chemical and mechanical compatibility with each application. The most common materials include NBR and HNBR for oils, greases and hydrocarbons, EPDM for chemicals and aqueous fluids, NR, SBR and BR for applications with high wear resistance, CSM for chemically aggressive environments and FKM for working with high temperatures and demanding chemicals. There are also versions in white or food-grade compounds for applications in the food, pharmaceutical and cosmetic industries, as well as formulations specially developed for transferring abrasive products that require high wear resistance and a long service life.
