ABSTRACT:
A pump (10) possesses a rotor (70), the rotor collar (120) of which laterally delimits a pumping duct (124) with an inlet (152) and an outlet. An axially adjustable sealing slide (182) bears sealingly against the rotor collar (120) on both sides in the axial direction and subdivides the pumping duct (124) between the inlet (152) and the outlet. A first bearing point for the drive shaft (60), for the supporting mounting of the drive shaft in the radial direction, is present within the clear space region occupied in the axial direction by the rotor (70).
