Abstract
An impeller designed to be mounted on a rotary shaft includes: a basic rim provided with blades protruding on one surface of the basic rim, and a hub capable of being coupled to the basic rim and to the rotary shaft. In certain embodiments, the impeller includes an annular plate and the hub, where the annular plate and the basic rim are configured to interact together so as to hold the basic rim axially and to maintain a freedom of radial deformation of the basic rim relative to the hub and to the annular plate.
