The invention relates to a helico-axial pump () for pumping a multi-phase mixture (M), said helico-axial pump () including a rotor () rotatably journalled in a pump housing () about a longitudinal axis (A), wherein the rotor () includes a compression stage (K) with a helico-axial impeller () and a stator () for the compression of the multi-phase mixture (M). In accordance with the invention a hydrodynamic stabilization element () having a stabilization surface () is provided in the pump housing () and designed such that a stabilization gap () is formed upstream of the stabilization medium, so that in the operating state a hydrodynamic stabilization layer (S) can be formed from a stabilization medium in the stabilization gap (S). The invention further relates to a rotor () for a helico-axial pump (), a method for the hydrodynamic journaling of a rotor () of a helico-axial pump () as well as to a hybrid pump with a rotor () for a helico-axial pump
