Abstract

A connector for connecting an impeller (1) to a shaft (2) is provided. The connector is formed as a unitary body. The connector has a sleeve portion (14) which is frictionally connected on a radially outer surface of a shaft side hub extension (H) of the impeller. The connector further has a threaded portion (12) carrying a thread which screws onto a corresponding threaded portion (7) of the shaft such that the connector provides a rotationally fixed connection between the impeller and the shaft. The hub extension has a central recess and a part (3) of the connector is inserted into the recess. The frictional connection between the sleeve portion and the radially outer surface of the hub extension transmits in use substantially all of the torque be¬ tween the shaft and the impeller.
