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, RuleMate’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:
• Higher Flow — optimized impeller to provideup to
10% more flow at the same amperage
• 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 — 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
• Hidden Air Vents in the Body — helps prevent air locking
in challenging plumbing installations and helps with the
check valve
• Threaded Discharge — easier installation, easier maintenance
