Rule Industries 53S 2000 GPH Automatic Computerized Bilge Pump 12V

The Rule Industries 53S is a 2,000 GPH automatic, fully submersible bilge pump engineered to commercial standards and trusted by leading boatbuilders worldwide. Featuring built-in computerized operation, this high-capacity 12-volt pump eliminates the need for a separate float switch — making installation simpler and allowing placement in tighter bilge spaces, including deep keel sumps and other hard-to-reach areas.

The 53S uses impeller-resistance sensing technology to automatically monitor your bilge. Every 2½ minutes the pump activates briefly to check for water. If resistance is detected, it continues running until the bilge is clear, then returns to its automatic check cycle — all without any manual intervention.
