ECCENTRIC SCREW PUMP

An eccentric screw pump has a stator, a rotor in the stator, a drive for the rotor, and a pump housing between the stator and the drive and having an opening between for receiving the medium being pumped. A releasable drive-end coupling connects a connecting shaft of the drive to a coupling rod, and...

description	An eccentric screw pump has a stator, a rotor in the stator, a drive for the rotor, and a pump housing between the stator and the drive and having an opening between for receiving the medium being pumped. A releasable drive-end coupling connects a connecting shaft of the drive to a coupling rod, and a rotor-end releasably connects the coupling rod to the rotor at a separation point. A rotor stub connects the rotor to the rotor-end coupling and is separable from the rotor at the separation point. A drive-end housing collar secures the pump housing to the drive. A rotor-end housing collar has a fixed first element fixed relative to the pump housing and an axially displaceable second element that is releasably fixable to the stator and that can be pushed axially toward the housing opening of the pump housing onto the first element to expose the separation point.
