摘要: A rotary piston pump has at least two rotors (8) with associated drive shafts (26), wherein for each rotor (8) an associated bearing tube (28) is provided, which extends into the associated rotor (8) and through which the associated drive shaft (26) passes. Between the inside (24) of each rotor (8) and the outside of the bearing tube (28) a first gap (64) is provided. In operation, the first gap (64) contains cooling fluid and is part of a cooling fluid circuit.
