Abstract (en)
[origin: EP2532833A1] The pump has a stator with internal screw threads for providing flow volumes (v1, v2), and a rotor (1) arranged in the stator. The rotor has thread pitches with an external screw thread (2) for providing one flow volume. Another external screw thread (3) for providing another flow volume is connected with the external screw thread along longitudinal direction, where the former flow volume is preferably 1.5 to 3 times higher than the latter flow volume. The internal and external screw threads are formed as integral parts.
