500GPH Automatic Bilge Pump 12V

Internal Float Switch - No Separate Switch Required

This 12V automatic submersible bilge pump is engineered for reliability and ease of installation. Equipped with a built-in electronic reed sensor, the pump automatically activates when water levels rise and shuts off once the bilge is clear, eliminating the need for a separate float switch. Designed specifically for RIBs, speedboats, and small marine vessels, it provides high-performance water evacuation in a compact, durable package.

RELIABILITY: Built with a water-cooled, long-life motor and ignition protection to meet marine safety standards.
