                  Item # 880198


                  Rule-Mate's Automatic Bilge Pump is an all-in-one, eco-friendly pump and switch that features solid state water-sensing technology that eliminates the need for a separate float switch.


                  • Powerful bilge pump and a new non-mercury float switch in a single housing
                  • While fully automated, the pump will only turn on when the water level rises
                  • There is no cycling and battery drain, the pump remains off until the internal float switch rises
                  • The pump then stays on until the water is evacuated
                  • Internal computer senses no load (water) against the impeller and then shuts off
                  • Quick release inlet strainer allows rapid cleaning
                  • A detachable strainer provides easy access to the impeller area for removal of debris
                  • For medium sized yachts and motor cruisers
                  • Improved switching with a protective mode
                  • Upgraded on/off mechanism. The previous design activates the pump using a magnet in a float "cube" and a reed switch to sense the water around the pump
                  • Water is sensed by an interruption in an electromagnetic field generated by the new circuit board
                  • To turn the pump off, the circuit board senses the amount of work the motor is doing (viaA draw) and once the circuit board senses the motor is doing less work, the board turns off the pump
                  • Circuit board includes a fail-safe feature which measures the amount of work the motor is performing and the length of time the motor is running
                  • If debris, such as a wet paper towel, becomes lodged against the pump, it could "trick" the pump into thinking water remained in the bilge which could deplete the vessel's battery
                  • When the circuit board senses the motor's running but not pumping water for longer than fifteen seconds, the pump will enter into a cycling mode in the same fashion as the computerized pumps
                  • Pumps turn off and activate the motor every two and a half minutes and if it senses water, it will continue to run until the water has been removed from the bilge
                  • After the debris is removed, the pump will automatically revert to the level sensing mode
                  • Rule Pumps carry a 3 year warranty from the date of purchase
