A coupling element for connecting a helix-shaped eccentric screw pump rotor to a drive shaft, with a drive shaft receiving portion and a rotor connecting portion arranged at an opposite end of the coupling element from the drive shaft receiving portion, the rotor connecting portion is constituted as a hollow cylinder for receiving a rotor end of the screw pump rotor, wherein the hollow cylinder has at least two inner circumferential surfaces which are complementary to the rotor and have a radius which is fixed with respect to the cross-sectional center of the hollow cylinder.

A method for fixing rotary pistons in a rotary piston pump and a method for dismantling rotary pistons of a rotary piston pump, where the rotary piston pump has two counter-rotating rotary arranged in a pump space on drive shafts. The rotary pistons each include a seating for the drive shafts. The respective drive shaft is arranged and fixed with an end region in the seating of the respective rotary piston. A diameter of the drive shafts in the end region can be widened elastically. In an operational state, in which the rotary pistons are arranged on the respective drive shafts, a frictional connection is formed between the respective seating of the rotary piston and the end region of the respective drive shaft.

A feeding device for an in-line screw machine with a shaft rotating in a feed container. A conveying screw is arranged in the direction toward the longitudinal axis of the rotating shaft. At least one disk wheel is allocated to each longitudinal side in the feed container. A separate drive is allocated to each disk wheel for purposes of rotational movement.

The invention relates to a clamping device which clamps the pump stator with the pump housing and an additional pump end part. The width of the clamping bars is at least 20% of the cross section of the pump stator in order to stabilise the clamping device and the simplify handling. All parts which are required to clamp the pump end part remain on the clamping bars.
