Abstract | The present disclosure relates to a centrifugal pump assembly (1) comprising- a pump head (11) for connecting to or being integral with a motor stool and/or a motor housing (63),- a pump base (5) defining a pump inlet (13) and a pump outlet (15),- at least one fluid outlet channel (53) for guiding pumped fluid from the pump head (11) to the pump outlet (15),- at least two rotor shaft segments (25a-d) coaxially aligned and extending along a rotor axis (z), wherein each of the rotor shaft segments (25a-d) comprises a first axial end (55) facing away from the pump head (11) and a second axial end (57) facing away from the pump base (57),- one or more impellers (3a-c) having a structure defining at least one impeller fluid channel extending from an impeller inlet (19) to an impeller outlet (21), wherein each of the one or more impellers (3a-c) is fixed to or structurally integral with one of the rotor shaft segments (25a-d), wherein the first axial end (55) of said one rotor shaft segment comprises a positive fit coupling with the second axial end (57) of another one of the rotor shaft segments (25a-d) for torque transfer between the at least two rotor shaft segments (25a-d), and- one or more pump stage housing segments (7a,b) arranged between the pump base (5) and the pump head (11), wherein each of the pump stage housing segments (7a,b) have a structure defining a guide passage (47) for receiving pumped fluid from the impeller outlet (21) of one of the one or more impellers (3a-c) and for guiding pumped fluid to the impeller inlet (19) of another one of the impellers (3a-c) or to the pump head (11),wherein the one or more pump stage housing segments (7a,b) each have a structure defining at least a part of a wall section of the at least one fluid outlet channel (53).
