Claim Text:
1. A helico-axial pump for conveying a multiphase mixture, which helico-axial pump includes a rotor rotatably journalled about a longitudinal axis in a pump housing and having a first part rotor and a second part rotor, wherein the first part rotor and the second part rotor include a compression stage having a helico-axial impeller and a stator for the compression of the multiphase mixture, and wherein a hydrodynamic stabilization bush having a stabilization surface is provided and formed between the first part rotor and the second part rotor such that a stabilization gap is formed before the stabilization surface so that a hydrodynamic stabilization layer can be formed from a stabilization medium in the stabilization gap in the operating state.
