Abstract (en)
[origin: WO2016041686A1] The invention relates to a stator for an eccentric screw pump comprising an inner cavity which has a helically coiled inner contour for accommodating a rotor. The stator comprises a stator core arranged in a stator casing, said core comprising at least two radially separable core parts. According to the invention, each of the at least two radially separable core parts is made of a metal material or an industrial ceramic material. The stator casing is a stator tube and is made of a metal material. The stator casing is shrunk onto the stator core. The invention further relates to an eccentric screw pump and a method for producing a stator.
