Rule 1100GPH Electronic Sensing Bilge Pump - 12V

The Rule 1100GPH Electronic Sensing Bilge Pump - 12V is a next-generation automatic bilge pump engineered for boats that require reliable water management without constant monitoring. This 12V electronic sensing bilge pump operates on an impeller resistance principle, automatically detecting water accumulation and activating only when needed, making it an efficient choice for cruisers, fishing vessels, and offshore boats where engine power and battery resources must be conserved.

The pump delivers 1100 gallons per hour (GPH) of displacement and operates on a smart sensing cycle: every 2.5 minutes, the pump runs for approximately one second to detect water. If water is present, the impeller experiences resistance and the pump continues running until bilge levels drop below the sensing threshold. Once water is cleared, the pump returns to its automatic 2.5-minute check cycle. This design maintains water levels between 1/8" and 3/8" of accumulation—tight enough to keep bilges dry without constant manual intervention or multiple redundant pumps.

The 1100GPH bilge pump is built for serious boaters who fish offshore, cruise extended distances, or operate in conditions where water intrusion is a routine concern. Weekend anglers benefit from the automatic operation during dockside sitting; offshore captains rely on the pump's 12V system efficiency to minimize parasitic battery drain while maintaining constant readiness. The compact form factor (7 x 4 x 7 inches) and light weight (1 lb) simplify installation in confined bilge spaces where larger displacement pumps would not fit.

Rule pumps are recognized throughout the marine industry for reliable flood prevention. The electronic sensing design eliminates the need for manual activation switches or redundant float switches in many applications, reducing complexity and potential failure points in the bilge system. This 1100GPH model sits in the mid-displacement range—adequate for boats up to the mid-30-foot range operating in fresh or light saltwater conditions where manageable seepage is expected.
