Abstract
An eccentric screw pump device has a screw stator, a screw rotor rotatably mounted in the screw stator, and a driveshaft that can be driven in rotation to impress a rotational movement of the screw rotor relative to the screw stator to deliver construction and/or thick material through the screw stator. The driveshaft projects into the screw stator or through the screw stator.
