Stator for an eccentric screw pump, an eccentric screw pump and a method for producing a stator

摘要

A stator for an eccentric screw pump with an internal hollow space with a helically coiled inner contour for accommodating a rotor. The stator includes a stator core arranged in a stator casing, which stator core includes at least two radially separable core parts. According to the invention, the at least two radially separable core parts are each made from a metallic material or a technical ceramic material. The stator casing is a stator tube and is made of a metallic material. The stator casing is shrink-fitted onto the stator core. The invention also relates to an eccentric screw pump and a method for producing a stator.
