PUMP AND CONTROLLER SYSTEM AND METHOD |
| 摘要 |
<p>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 fioat device (40) that activates a pump motor (12) when water within a housing (30) of the pump (10) reaches a high water level. The pump deactivation mechanism includes a sensor (104) that detects the load on the pump motor (12) and deactivates it when the sensed load indicates that the water within the pump housing (30) has reached a low water level.</p> |
