A liquid pump and controller with separate pump activation and deactivation mechanisms that are both closed detector devices is provided. The pump activation mechanism includes a float device that activates a pump motor when water within a housing of the pump reaches a high water level. The pump deactivation mechanism includes a sensor that detects the load on the pump motor and deactivates it when the sensed load indicates that the water within the pump housing has reached a low water level.
L'invention concerne un ensemble pompe et commande de liquide avec des dispositifs d'activation et de désactivation de pompe séparés, qui font office de dispositifs détecteurs fermés. Le mécanisme d'activation de pompe comprend notamment un dispositif flotteur destiné à activer un groupe électropompe lorsque l'eau contenue à l'intérieur du corps de ladite pompe atteint un niveau élevé. Le mécanisme de désactivation de pompe comprend un capteur conçu pour détecter la charge sur ledit groupe électropompe, et pour désactiver ce dernier lorsque la charge détectée indique que l'eau contenue à l'intérieur du corps de la pompe a atteint un niveau bas.
