Abstract

Ce dispositif de pompage des liquides fonctionne par aspiration et comprend une chambre d'aspiration 3 logée dans la cuve réceptrice 2 et raccordée par une conduite 10 à la cuve d'alimentation 1. La cuve réceptrice 2 doit être remplie jusqu'à un niveau qui recouvre les orifices de sortie de la pompe centrifuge 40. Seuls le corps de la pompe, le rotor et la partie basse de l'arbre de celui-ci sont immergés dans le liquide. La pompe aspire par un tube 12 au fond de la chambre 3, remplie de liquide au moins au niveau V, la zone supérieure (et la conduite 10 à l'arrêt) étant remplie d'un gaz neutre, la dépression engendrée par la pompe dans ce gaz provoquant l'aspiration du liquide de 1 vers 2 par la conduite 10. L'invention s'applique notamment au pompage des métaux liquides, notamment du magnésium liquide.
