Abstract

Une pompe à entraînement magnétique comprend un dispositif d'accouplement magnétique comprenant un rotor magnétique externe et un rotor magnétique interne. Le rotor magnétique externe est entraîné par un moteur séparé. Le rotor magnétique externe est positionné radialement vers d'extérieur d'une paroi d'étanchéité. Le rotor magnétique interne est positionné radialement à l'intérieur de la paroi étanche de sorte que la rotation du rotor magnétique interne entraîne la rotation du rotor de pompe. Le rotor de pompe entraîne une tête de pompe de pompe centrifuge à déplacer le liquide. Un détecteur de bulle est positionné vers l'extérieur de la paroi de sorte à être du côté sec de la pompe. Le détecteur de bulle envoie un signal sur un côté humide de la pompe pour signaler la présence d'un gaz dans le fluide de la pompe.
