Abstract

a. Pompe centrifuge comprenant un arbre d'entraînement, un moteur monté fixe sur cet arbre d'entraînement, et un corps de pompe comprenant un passage d'entrée communiquant avec le moteur et un carter en spirale définissant un espace en spirale autour du moteur. b. Pompe centrifuge caractérisée en ce que le moteur comprend un disque principal muni d'un moyeu monté fixe sur l'arbre d'entraînement et un certain nombre de palettes montées avec des espacements égaux entre elles et faisant saillie axialement d'un côté au moins du disque, les majeures parties de la face avant d'une palette et de la face arrière de la palette adjacente avec laquelle elle définit un passage de fluide, étant constituées par des segments de cercles de diamètres différents centrés en des points différents du disque de façon que le passage formé entre ces deux palettes présente une profondeur constante et une largeur progressivement décroissante lorsqu'on part de la zone voisine du moyeu pour aller vers le pourtour extérieur du disque. c. L'invention s'applique dans le domaine des pompes à fluide.
