Abstract (en)
The turning lock is for the elastomer stator of an eccentric screw conveyor pump. The metal jacket round the elastomer cover has at least one radial stud which can act as a stop on the fixed part of the pump. The jacket (1) has a threaded element, e.g. a nut (8), into which the stud (7), with a corresponding external thread, can be screwed. A free separate part of the stud may have a hose-like covering (11) of elastomer or thermoplastic.
