Rotors for progressing cavity pumps

We produce single, dual, and multiple-lobe rotors for all pumping needs - adjusted for a wide range of different substances. For example, we can easily produce components of up to 8 meters in length. Together with our customers, we develop new rotor geometries with special heads, using continuously updated 3D design software.

For our standard rotors we use stainless steel 1.4571 or AISI 316 ti as well as tool steel 1.2436 vacuum-hardened to 61 HRC. Of course we also work with other materials if required.

Rotors are often used at high temperatures, for which we naturally adjust the rotor dimensions in accordance with the respective expansion.

In order to ensure the maximum operating life even under the toughest conditions in ever expanding areas of application, we offer comprehensive coating technologies such as hard chrome-plating and carbide (e.g. tungsten carbide, chormium carbide).
