Abstract

The invention relates to a helico-axial pump () for conveying a multiphase mixture (M), which helico-axial pump () includes a rotor () rotatably journalled about a longitudinal axis (A) 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 (K, KE, KA, KE KA) having a helico-axial impeller () and a stator () for the compression of the multiphase mixture (M). In accordance with the invention, 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 (S) is formed from a stabilization medium (M) in the stabilization gap () in the operating state. The invention further relates to a rotor () for a helico-axial pump (), to a hybrid pump having a rotor () for a helico-axial pump () as well as to a method for the hydrodynamic journalling of a rotor () of a helico-axial pump ().
