Abstract (en)
The pump (1) has a pump body (2) with a screw-like rotor (5) rotatable relative to the pump body. The rotor is coupled with a driving motor by a connecting unit, where the rotor is rotatable by the driving motor. The connecting unit is designed as a connecting shaft (15) rotatably supported in the pump body. The connecting shaft is sealed to the pump body by a sealing element (17), and the rotor is detachably arranged at the connecting shaft. The connecting shaft is designed as a hollow shaft (19) into which a connecting bolt (20) is inserted, where the bolt is screwed into the rotor.
