Abstract

Le corps de cette pompe est constitué par l'assemblage d'une enveloppe extérieure de forme simple en métal embouti et d'une volute en matière plastique moulée, emboîtée dans l'enveloppe extérieure précitée, faisant office de paroi de séparation entre les orifices d'aspiration et de refoulement et dont le profil permet le guidage du fluide entre les orifices précités tout en procurant un bon rendement hydraulique.
