Abstract

La présente invention concerne un système de pompage de précision. Le système de pompage comprend un ensemble moteur électrique alimentant un premier arbre d'entraînement entraînant une première pompe à un premier débit et alimentant un second arbre d'entraînement entraînant une seconde pompe à un second débit. Une sortie de fluide proportionnelle comprend un premier fluide pompé par la première pompe et un second fluide pompé par la seconde pompe. Le système de pompage offre un rapport souhaité du premier fluide sur le second fluide au niveau de la sortie de fluide proportionnée, relativement indépendamment de la pression et du débit au niveau de la sortie.
