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.
Our 10 stamping lines produce forces up to 3150 kN and our 19 mechanical and hydraulic presses generate forces up to 3150 kN (toggle press up to 10,000 kN). This ...
Our state-of-the-art stamping machines generate forces from 400 kN to 3150 kN and produce elastomer flat gaskets in quantities from 1000 to 3 million units per year. ...
