Stator for an eccentric screw pump comprises axially arranged stator segments connected pressure-tight on their contact points by a tube pulled onto a casing and overlapping the contact points and a radially flattened metal ring

摘要

Stator comprises axially arranged stator segments (2, 3) connected pressure-tight on their contact points (12) by a tube (15) pulled onto a casing (4) and overlapping the contact points and a radially flattened metal ring (16). The tube is made fro a polymeric material. An independent claim is also included for a method for producing a stator. Preferred Features: The casing has smooth walls or is coiled. The stator segments with the casing are combined with each other. The stator segments have different geometries.
