Beschreibung
Zusammenfassung:	A connector, for connecting an impeller 1 to a shaft 2, has first second subcomponents. The first subcomponent has a first sleeve portion 3, and the second subcomponent has a second sleeve portion 14 which is sandwiched between the first sleeve portion and the hub extension. The second sleeve portion is frictionally connected on one side with the first sleeve portion and on the opposing side with the hub extension. The first subcomponent further has a threaded portion which screws onto a corresponding threaded portion of the shaft. The second subcomponent is formed of a material having a coefficient of thermal expansion which is intermediate the coefficients of thermal expansion of the materials of the impeller and the first subcomponent. The impeller may be made of an aluminium alloy, the first subcomponent may be made of a high tensile or medium carbon steel, and the second subcomponent may be made of stainless steel, bronze or brass.
