Abstract

Il est décrit certaines réalisations de la présente invention décrivant une pompe ayant un moteur, un carter, une plaque d'étanchéité couplée au carter et ayant un moyeu de la plaque d'étanchéité équipée de supports de montage, une roue à aubes disposée dans le carter, un ensemble de couplage qui couple larbre du moteur et un arbre de pompe ainsi quun joint d'étanchéité et un ensemble de levage comprenant une garniture mécanique et une garniture de joint d'étanchéité. La garniture de joint d'étanchéité se couple de façon amovible aux supports de montage et comprend des ouvertures de levage filetées qui sétendent sur le plan axial à travers la garniture de joint d'étanchéité. La configuration de chaque ouverture de levage filetée lui permet de recevoir un élément de levage. Une fois découplée des supports de montage, la garniture de joint d'étanchéité peut effectuer un déplacement axial entre une première position, dans laquelle la garniture de joint d'étanchéité engage la garniture mécanique, et une deuxième position, dans laquelle la garniture de joint d'étanchéité engage une bague de retenue couplée à larbre de pompe par suite de la rotation des éléments de levage vissés dans la paire douvertures de levage filetées.
