Abstract:
1. An apparatus for delivering viscous delivery material using an eccentric screw pump, comprising: a framework for carrying and fastening apparatus elements; a pump-housing portion for carrying a stator and a rotor, which is mounted for rotation in the stator and is in the form of a delivery screw; a suction region for introducing the delivery material; a pressure region for discharging the delivery material; an electric drive unit for driving the rotor in the stator in a first direction of rotation for delivering the delivery material; a control mechanism for activating the drive unit; at least one releasable retaining member for at least one of a rotationally fixed connection and a positionally fixed connection between the drive unit and the stator; wherein a change in the direction of rotation to a second direction of rotation of the electric drive unit, with the retaining member released, gives rise to automatic separation of the pump-housing portion with the stator by virtue of the rotor being unscrewed.
