Abstract
A connected impeller and shaft is provided. The shaft has a first part which provides a threaded portion carrying a thread which screws onto a corresponding threaded portion of the impeller. The shaft also has a second part which provides an abutment surface for engaging a corresponding abutment surface of the impeller when the threaded portions are screwed together, thereby tightening the threads to provide a rotationally fixed connection between the impeller and the shaft. The first part is rotationally fixed relative to the second part at a joint. The threaded portion of the shaft is axially spaced a first distance from the abutment surface of the shaft. The threaded portion of the shaft is axially spaced from the joint by a second distance which is greater than the first distance. The threaded portion of the shaft and the joint are on the same side of the impeller.
