Progressive cavity pumps consist of two components: The rotor and the stator. The term rotor refers to the metal shaft inside the rubber tube, the stator.
The rotation of the rotor creates a powerful suction effect that pulls the material into the cavities of the stator. It is important that the shape of the rotor matches the geometry of the stator precisely. We therefor recommend precisely drilled high alloy tool steel rotors.
We also carry more economical cast iron rotors for several models. Cast iron can be an adequate option, but do keep in mind that rotor heads are more likely to break off with cast iron rotors.
Here we list our most popular rotors. Search our rotor stator sets if you are looking for the accompanying stators. Don't see what you need? Contact us, and our sales team will be happy to find a solution that fits your needs.
The rotors are organised by stator diameter.
