The invention relates to an eccentric screw pump, including a rotor, which forms a conveying screw, and a stator, which forms a screw flight and in which the rotor rotates during conveying operation, wherein: the stator includes a stator housing, in which a stator lining is disposed, the stator lining reproducing the screw flight; the stator lining is a sleeve which is supported, at its outer periphery, on the stator housing by means of a support structure which forms cavities; the support structure is designed and dimensioned, in accordance with the location of its connection to the sleeve, in such a way that the supporting effect provided by the support structure is matched to the local needs of the sleeve.

Eccentric screw pump having a stator linking which is simpler to produce

A pump housing for an eccentric screw pump, with a longitudinal axis and a hollow space constituted running axially between a drive-side opening and a pump-side opening, wherein the pump-side opening is enclosed by a main housing body and a lid fastened removably thereto, wherein the main housing body includes a ring segment-shaped axial guiding surface lying opposite the lid.

Pump housing for an eccentric screw pump and an eccentric screw pump equipped therewith

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.
