Abstract
Stator for an eccentric single-rotor screw pump has a casing made of steel or the like and a helical elastomer lining. Stator and a method for its production are described which can also be made with larger lengths at low production costs. Stator is composed of at least two stator segments that are axially arranged in a line, whereby the stator segments are connected to one another at their abutment so as to be pressure-tight by a tube of a polymer material that is pulled onto the casing and overlaps the abutments and by a metal ring radially pressed onto it.
