RULE RM500B GPH AUTOMATIC BILGE PUMP

500 GPH/1890 LPH, 3/4" hose diameter. The RuleMate bilge pump operates using an internal level sensor. When water reaches 2", the pump will automatically activate, removing water from the bilge. When the water level reaches 3/8", 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.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.
