Abstract

The invention relates to a clamping device which clamps the pump stator with the pump housing and an additional pump end part. The width of the clamping bars is at least 20% of the cross section of the pump stator in order to stabilise the clamping device and the simplify handling. All parts which are required to clamp the pump end part remain on the clamping bars.
