Kölle Werkzeugbau und Stanzerei
One of our special products is the tubular rotor for progressive cavity pumps. In order to manufacture these tubular rotors, we use steel pipe material S235JR+AR/St37-2 and S355J2+N/St52-2 and stainless steel 1.4301, 1.4404 and 1.4548. The diameter of these tubular rotors can be as small as 32 mm up to a maximum of 132 mm. The wall thicknesses range from 3 mm to 5 mm, while the rotors can be up to 8 m long and uses a left- or right-hand helix. The tight tolerance of the diameter is only ± 0.1 mm and even without re-machining, the surface quality remains very high. We use toggle presses that exert a force of up to 10,000 kN to produce our rotors.
