Abstract

De conformidad con el presente, un impulsor para ser usado en una bomba centrífuga tiene al menos un aleta cuyo extremo terminal externo está configurado para producir un perfil de velocidad de flujo que controla y reduce el desgaste causado por fluido aguado que es expulsado del impulsor en la superficie interna de la carcasa. Las aletas del impulsor del presente están configuradas, por lo general, con una porcion que se extiende externa y radialmente, en comparacion con el borde concavo o recto convencional de una aleta del impulsor. La porcion que se extiende externamente puede variar en forma, pero debe ser seleccionada para producir un perfil de velocidad de flujo que reduzca el desgaste en la carcasa de la bomba.
