The pump has a nozzle (2) including a nozzle outlet (2b) and a diffuser (3) with a diffuser inlet (3a), lying downstream to the nozzle, where the nozzle extends up to the diffuser inlet. A cross section of a main inlet (1a) is smaller than the cross section of a side inlet (1b). The nozzle extends over width of the side inlet. A set of nozzle areas (21, 22) is connected by an adhesive joint and/or by a friction welding process and/or is formed integrally as a single-piece part. The nozzle is arranged in a cross section-extended section of the pump. |
