Allweiler Produces its Own Stators

With its own stator production, it can make sure that even uncommon elastomers and dimensions will be available quickly and in original quality.

Only very few manufacturers of progressing cavity pumps can assure their customers and users that their products contain stators from their own production. In most cases, stators are procured from external suppliers who work for several different pump manufacturers. Manufacturers need special machines and knowledge to process elastomers properly and they must also have the ability to adjust the properties of various elastomer grades to the respective pumping task. Although five different grades of elastomer can cover about 70 to 80 percent of all applications, another fourteen elastomer types are needed to provide the best possible solutions for the remaining applications.

Allweiler produces about 10,000 progressing cavity pumps every year and delivers these products around the world. Allweiler AG purchased the machines and know-how from its long-time supplier New-York Hamburger Gummi-Waaren Compagnie AG in order to gain independence from external suppliers and also facilitate delivery of less common elastomer types and sizes. All of the New-York Hamburger employees working in this area have become employees of “Allweiler Stator Production” in Hamburg, Germany.

“This development will bring several benefits for Allweiler customers and the operators of progressing cavity pumps,” according to Board Speaker Klaus Stahlmann. “The original quality will be guaranteed for all elastomers, delivery will be fast and economical, and we will be able to fulfill special needs on a short-term basis.” In addition, Allweiler plans to increase its investments in the research and development of materials and processing methods.
