Rule Bilge Pump, Automatic 500GPH. The RuleMate bilge pumps operate using an internal level sensor. When water reaches 2" (5 cm), the pump will automatically activate, removing water from the bilge. When the water level reaches 3/8" (0.9 cm) the pump will turn off until the water level rises again.
Bilges are not always clean and free from debris. If the level sensor becomes fouled by debris or contaminated water, RuleMate's unique back up feature will prevent the pump from entering a run-on condition, protecting the battery while maintaining automatic operation.
500 GPH pump with optimized impeller to provide up to 10% more flow at the same amperage
Auto Sense Intelligence which has an integral water level sensor that controls the pump automatically
Back Up Feature prevents continuous running if sensor is fouled by debris, pump reverts to 2.5 minute cycle mode
Smaller Footprint: new RuleMate is 2/3 the size of existing model
Built-In Thermal Cut-Off (TCO): provides added protection for pump and vessel

Back Flow Prevention: reduces the amount of water left over in the bilge, reducing odor and helping keep your bilge cleaner
