Les pompes \u00e0 membrane et \u00e0 piston sont toutes deux utilis\u00e9es pour doser les liquides, mais diff\u00e8rent dans la mani\u00e8re de proc\u00e9der.<\/div>\n<\/div>\n
\n
Le premier utilise une membrane flexible qui se d\u00e9place d'avant en arri\u00e8re pour aspirer et doser le liquide. Lorsque la membrane se d\u00e9place vers l'int\u00e9rieur, elle cr\u00e9e une pression n\u00e9gative \u00e0 l'int\u00e9rieur de la t\u00eate, aspirant ainsi le liquide. Lorsque la membrane se d\u00e9place vers l'ext\u00e9rieur, le liquide est expuls\u00e9 de la pompe.<\/div>\n<\/div>\n
\n
La seconde utilise un piston qui se d\u00e9place d'avant en arri\u00e8re \u00e0 l'int\u00e9rieur d'une t\u00eate hydraulique. Lorsque le piston se d\u00e9place vers l'int\u00e9rieur, il cr\u00e9e une pression n\u00e9gative \u00e0 l'int\u00e9rieur du cylindre, aspirant le liquide. Lorsque le piston se d\u00e9place vers l'int\u00e9rieur, le liquide est pouss\u00e9 hors du cylindre.<\/div>\n<\/div>\n
\n
En g\u00e9n\u00e9ral, la pompe \u00e0 membrane est pr\u00e9f\u00e9rable pour le dosage de liquides abrasifs ou peu visqueux. La pompe \u00e0 piston est g\u00e9n\u00e9ralement plus efficace avec les liquides visqueux dans les syst\u00e8mes n\u00e9cessitant une pression de fonctionnement \u00e9lev\u00e9e.<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
