Abstract

Un rotor amélioré destiné à une pompe à boue centrifuge est présenté et comprend un carénage de dessus; un carénage de fond et une partie de milieu entre les deux, ladite partie de milieu comportant au moins une paroi substantiellement verticale définissant un canal d'écoulement de boue, où le carénage de dessus, le carénage de fond et la partie du milieu sont configurés comme une seule pièce pour définir ensemble un premier corps unitaire; au moins un nez de pale est positionné au rebord d'attaque de la au moins une paroi substantiellement verticale et, facultativement, une bague de retenue est installée sur le carénage de dessus pour fixer le nez de pale à l'intérieur du corps.
