Abstract
The pump (20) has a rotor (80) rotatable by a drive in a pump duct (25). The rotor (80) has a pump element (90) with undulating boundary faces extending radially. The boundary faces are bounded cylindrically and run in a fitted manner in a cylindrical conveying region (27), their highest points running adjacent to the end faces (35) of the pump duct in a sealed manner. In addition, a sealing slide (31) is provided, which is displaceable parallel to the axis of rotation (76) and which seals off the pump duct (25) between the inlet (22) and the outlet (23), so that during rotation the rotor (80) follows the undulating movement of the boundary faces (96) of the pump element (90). In addition, sealing means seal off the media-conveying pump chambers from the housing (21). The rotor (80) is detachably connected to the drive shaft (180) while forming connecting boundary faces, which are arranged on the drive side on the other side of the sealing means with respect to the media-conveying pump chambers.
