Abstract (en)
[origin: WO2006015574A1] The aim of the invention is to improve the sealing possibilities between the elastic stator lining and corresponding connecting flanges of eccentric screw pumps. In order to increase the sealing surfaces, the stator lining comprises, at least at one of its ends, a conical sealing surface which may be provided with one or more prominent or recessed parts (26, 28, 30).
