An eccentric screw pump with an annular outer part () and an inner part () arranged therein has an interior of the outer part () and an exterior of the inner part () tapering in a complementary manner towards an axial end (). In the axial direction (X, W), the inner part () and the outer part () are movably received in relation to each other and the inner part () and/or the outer part () are configured in such a manner that pressure applied to the pressure side of the eccentric screw pump generates a force that acts upon the inner part () axially to the direction in which the inner part () tapers and/or a force that acts upon the outer part () in an opposite axial direction.
