Abstract
Pompe submersible munie de moyens d'étanchéité destinés à éviter les fuites indésirables du fluide pompé Deux pompes auxiliaires refoulent l'une le fluide pompé et l'autre le fluide du moteur hydraulique vers une chambre commune maintenue sous pression et munie de moyens pour conduire vers l'extérieur le mélange de fluide. Ceci permet d'éviter la pénétration de gaz dangereux à l'intérieur de la chambre Applicable aux pompes submersibles en général.
