Abstract (en)

[origin: EP2386767A2] The helico-axial pump (1) comprises a partial rotor (21) and a rotor which is arranged in pump housing (6) around a longitudinal axis (A) in a rotating manner. The partial rotor comprises a compression level (K) having a helico-axial propeller (3) and a stator (4) for compression of multiphase mixture (M). A hydrodynamic stabilization bush (70) is arranged with a stabilization surface (700), where a stabilization gap (8) is formed for the stabilization surface. Independent claims are also included for the following: (1) a hybrid pump with a rotor; and (2) a method for hydrodynamic support of a rotor.
