Abstract (en)
[origin: EP2278164A2] The pump (2) has a stator (8) comprising an inlet end (21) for coupling to a fluid-receiving casing (20). An anchor element (36) comprises legs and clamping arms. The legs are supported on and fastened to a stationary plane support (38). The clamping arms clamp the inlet end of the stator. The inlet end and the clamping arms include locking units for locking, in rotation, the inlet end and the clamping arms. The locking units have stator relief portions co-operating with two anchor relief portions. An independent claim is also included for a pump device comprising a drive shaft.
