Rule 500GPH Electronic Sensing Bilge Pump - 24V

The Rule 500GPH Electronic Sensing Bilge Pump - 24V is the workhorse every serious boat owner trusts for automatic water management below deck. Whether you're running a fishing charter, cruising coastal waters, or moored in a slip, unwanted bilge accumulation can threaten your vessel's integrity and safety. This pump eliminates the guesswork with intelligent electronic sensing that detects water before it becomes a problem, running maintenance cycles throughout the day and night so you can focus on what matters—your time on the water.

Built on Rule's proven impeller-resistance sensing principle, the 500GPH 24V S-series pump operates on a smart duty cycle: every 2.5 minutes, it runs for approximately one second to sense for water presence. If moisture is detected, the pump automatically engages full flow to discharge accumulated bilge, then cycles back to monitoring mode. This approach minimizes power draw on your boat's electrical system while maximizing responsiveness, making it ideal for extended cruising where shore power isn't always available. The compact design (measuring 7 x 4 x 7 inches and weighing just 1 pound) fits easily into tight engine compartments without compromising performance.

This 24-volt configuration suits larger vessels, fishing boats, and commercial applications where 24V DC electrical systems are standard. The Rule 500GPH pump handles moderate water removal demands—500 gallons per hour ensures steady evacuation without overloading your thru-hull fittings or electrical infrastructure. Installation works best with proper 24V power supply, through-hull drainage, and intake strainer protection; consult your boat's electrical schematic to confirm amperage compatibility. Whether you're protecting a center console, cruiser, or work boat, this electronic sensing bilge pump delivers the reliability anglers and boaters depend on for safe, worry-free operation.
