Rule Automatic Bilge Pump

Rule Automatic Bilge Pumps check for water every 2 1/2 minutes and keep bilge water at the lowest level of any automatic bilge pump. A standard pump and float switch allows water to reach 2" (5 cm) before it activates. Rule Automatic Bilge Pumps activate at 5/8" (1.6 cm) and drain water down to 1/4" (0.6 cm). Rule bilge pumps provide ultimate pumping performance, which helps keep your bilge clear of nuisance water. Engineered and tested to the highest standard, achieving rated performance at 12V, resulting in high flow with best-in-class efficiency for the toughest applications. Features: Automatic water sensing (no separate float switch required) Optimized impeller to provide greater flow at the same amperage Compact, efficient, long-life motors with ability to run dry for short periods Back Flow Prevention (500 - 1100 models only) Hidden air vents in the body help prevent air locking Easy-clean, snap-lock strainer bases Stainless steel shafts Completely submersible Marine-grade bloc
