Pump and controller system and method

摘要

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.
