Abstract
An empeller for a centrifugal pump comprises a disc (1) and blades (2), which comprise a number of band elements (4'), each formed by a length of a band (4) and finished at each end with band loops (42). The loops (42) are slipped over consoles, rigidly and with equal spacing fastened to said disc along its perimeter and the band elements (4') are stretched towards the centre of the disc by means of tension devices (5).
