The new RuleMate bilge pumps operate using an internal level sensor. When water
reaches 2" (5cm), the pump will automatically activate, removing water from the
bilge. When the water level reaches 3/8" (0.9cm) 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, Rule Mate’s unique back
up feature will prevent the pump from entering a run-on condition, protecting the
battery while maintaining automatic operation.
Our new designs include:

PRODUCT FEATURES

• Higher Flow — optimized impeller to provide up to 10% more flow at the same amperage as previous models with capacities from 500-2000 GPH (1893-7571 LPH)
• Auto Sense Intelligence — integral water level sensor 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 — 2/3 the size of previous models (500-1100 GPH models only)
• 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 (500-1100 GPH models only)
• Hidden Air Vents in the Body — helps prevent air locking in challenging plumbing installations and helps with the check valve (500-1100 GPH models only)
• Threaded Discharge — easier installation, easier maintenance
