Abstract

La présente invention concerne une pompe centrifuge à ailettes comportant un corps de pompe, un couvercle de pompe et un arbre de pompe. L'arbre de pompe est muni d'au moins une ailette qui renferme au moins deux canaux. Un anneau d'étanchéité de corps de pompe est disposé dans la chambre de pompe sur la partie qui correspond à la section entre des sorties de canaux de chaque deux ailettes. La pompe centrifuge peut équilibrer la force axiale, réduire la perte de charge et améliorer l'efficacité de la pompe.
