Rule-Mate Automatic Submersible Bilge Pumps 12V with Auto Sense Intelligence

The Rule-Mate Automatic Submersible Bilge Pump family provides dependable, hands-free bilge water removal for boats. Offered in 500, 800 and 1100 GPH variants, these 12V pumps deliver up to 10% more flow without increasing amperage. Auto Sense Intelligence automatically activates at 2" of water and shuts off at 3/8", with a backup cycle that runs every 2.5 minutes if the sensor becomes blocked, helping prevent overflow. Additional features common to the line include thermal cut-off protection, built-in backflow prevention, hidden air vents to reduce airlocks, and a compact threaded discharge for straightforward installation in tight spaces. Engineered for reliable marine use, Rule-Mate pumps are designed to keep bilge areas dry and protect vessels in everyday and emergency situations.
