摘要： What is concerned is an eccentric screw pump having at least one stator (1), a rotor (2) rotating in the stator, a drive (3) for the rotor, a pump housing (4) which is connected to the stator (1) and has at least one inlet opening (6) for the medium to be conveyed, a connection housing (14) arranged between the pump housing (4) and drive (3), a connection shaft (9) which is connected to the drive (3) and is arranged at least in certain regions in the connection housing (14), and a coupling rod (10) which is arranged in the pump housing (4) and is connected to the connection shaft (9) via a drive-side joint (11) and to the rotor (2) via a rotor-side joint (12). The drive-side housing connection piece (16) can be demounted in such a way that the drive-side joint (11) can be exposed for maintenance or demounting.

摘要： The invention relates to an eccentric screw pump, comprising at least one stator (1) composed of an elastic material and a rotor (2) that can be rotated in the stator (1), the stator (1) being surrounded by a stator casing (3) at least in some regions. The stator casing (3) consists of at least two casing segments (19) as a longitudinally divided casing and forms a stator clamping device, by means of which the stator (2) can be clamped against the rotor (1) in the radial direction. The pump is characterized in that the casing segments (19) have at least one clamping flange (20) having first clamping surfaces (21) at each end of the casing segments and that one or more clamping elements (22, 23), which can be displaced in the axial direction and have second clamping surfaces (24), are placed onto the clamping flange (20), the first clamping surfaces (21) and the second clamping surfaces (24) being designed in such a way and interacting in such a way that the stator casing (3) can be clamped against the stator in the radial direction in the course of an axial displacement of the clamping elements (22, 23).
