HELIC-AXIAL PUMP, ROTOR FOR A HELIC-AXIAL PUMP, AS A METHOD FOR CARRYING OUT A ROTOR IN A HELICAL-AXIAL PUMP.The present invention relates to a propeller pump (1) for transporting a multistage mixing (M), helical-axial pump (1) which includes a rotor (2) which rotates about a longitudinal axis (A) in a pump housing (6) and has a first rotor component (21) and a second component rotor (22), wherein the first component rotor (21) and the second component rotor (22) include a compression stage (K, K1E, K1A, K2E, K2A) having a propellant. helical-axial (3) and a stator (4) for compressing the multistage mixture (M). According to the invention, a hydrodynamic stabilizer bushing (70) having a stabilizing surface (700) is provided and formed between the first component rotor (21) and the next component rotor (22), such that a stabilizing clearance (8) is formed before the stabilizing surface (700), such that a hydrodynamic stabilizing layer (S) is formed from a stabilizing means (M) on the stabilizing clearance (8) in the operating state. The invention further relates to a rotor (2) for a helical-axial pump (1), a hybrid pump having a rotor (2) for a helical-axial pump (1), and a method for hydrodynamic trajectory of a rotor (2) of a helical-axial pump (1).
