The insert 24 can be inserted into the tubular stator can, and no precise adjustment of rotor and 45 22 are pressed. The wall of the stator can Mator is necessary. In this case, however, the stator has a non-uniform thickness, possibly also a non-uniform one relatively thick wall thickness in order to have uniform elasticity between ro- gate and stator, especially when the pump starts up, so that the
