The rotor shafts (14) are arranged together with the rotors (10, 12) in a pump housing (16, 18), wherein a plurality of pump stages are formed by the pump housing and the corresponding rotor pairs (10, 12). In order to simplify assembly, the rotor shafts (14) form a single piece together with the associated rotors (10, 12) and the pump housing is formed in two parts. In a preferred embodiment, a separation plane (24) of the pump housing (16, 18) runs transversely across the rotor shafts (14).
