PUMP AND CONTROLLER SYSTEM AND METHOD

摘要

A liquid pump (10) 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 (40) that activates a pump motor (12) when water within a housing (30) of the pump (10) reach a high water level. The pump deactivation mechanism includes a sensor (104) that detects the load on the pump motor (12) and deactivates the pump motor (12) when the sensed load indicates that the water within the pump housing (30) has reached a low water level.
