Abstract

Se describe un impulsor de una bomba centrifuga. El impulsor tiene una entrada a traves de la cual el fluido pasa al impulsor, asi como paletas de bombeo para bombear el fluido de la entrada y expulsar el fluido a una camara de bombeo de la bomba centrifuga en la que funciona el impulsor. El impulsor tambien tiene al menos un protector que se extiende radialmente desde un eje de rotacion para el impulsor y se acopla a las paletas de bombeo, el al menos un protector que tiene una porcion plana ubicada hacia un centro del impulsor y una porcion ahusada ubicada hacia un borde exterior del protector, la porcion ahusada tiene una forma compuesta y tiene una region concava y convexa.
