The pump has a housing of cylinder (1) and cover (8A), and a rotor (3) with rotary slides. There is power introduction on at least one side of the rotor via a centering shaft section (13). The section forms part of a further cover element (8B) and is connected to the rotor via fastener elements, so that in extension of the drive shaft (7), a drive shaft (7') with second increased diameter (d2) is formed. A chamber (4) formed between drive shaft and internal rotor wall (21) is connected via channels (5) to the pump chamber (19) between two rotary slides.
