FIELD: engines and pumps.
SUBSTANCE: proposed device is intended for clamping one-screw pump stator. The latter is arranged between pump case and its extreme part. Note that at least two tightening plates 28, 30 are arranged between pump case and its extreme part to joint them together. Width of said plates makes at least 20% of the diametre of stator 18. There are at least two points or surfaces to transfer clamping force on one narrow end side of said plates.
EFFECT: simplified assembly and servicing, higher stability of jointed parts.
