Abstract

La présente invention concerne un ensemble manchon de protection utilisé pour une pompe à moteur chemisée, appartenant au domaine technique des pièces de pompe à moteur chemisée. L'invention résout les problèmes d'étanchéité médiocre des ensembles manchons de protection existants et des nombreux matériaux utilisés dans la fabrication. Le présent ensemble manchon de protection utilisé pour une pompe à moteur chemisée comprend un corps de protection et un couvercle de protection joint à celui-ci, le corps de protection étant pourvu d'un couvercle supérieur creux formé d'un seul tenant à une extrémité du corps de protection à l'opposé du couvercle de protection, et l'extrémité intérieure du couvercle supérieur étant pourvue d'un siège de palier relié de manière fixe à celui-ci et disposé de manière coaxiale avec celui-ci. La présente invention possède une bonne étanchéité et réduit certains matériaux de fabrication.
