Abstract (en)
[origin: WO2018087254A1] The invention relates to an eccentric screw pump comprising at least - a stator (1), a rotor (2) rotating about the stator, a drive (3) for the rotor (2), a pump housing (4) connected to the stator (1) and comprising at least one housing opening (6) for the medium to be conveyed, a connecting shaft (9) connected to the drive (3), a coupling rod (10) arranged in the pump housing (4) and connected on the drive side to the connecting shaft (9) via at least one detachable drive-sided connecting range and is connected to the rotor side of the rotor (2) via at least one detachable rotor-sided connecting range, the pump housing (4) comprises a drive-sided housing connection (16) and a stator-sided housing connection (17). The pump is characterised that rotor-sided housing connection (17) comprises a fixed first connection section (17a) and a displaceable second connection section (17b) which can be displaced axially on the first connection section (17a) in the direction of the housing opening (6) of the pump housing (4) for exposing the rotor-sided connection range.
