New 2020 Rule-Mate Automatic Bilge Pump 800 GPH 12 Volt RM800B


Higher Flow — 800 GPH pump with optimized impeller to provide up to 10% more flow at the same amperage Back Up Feature — prevents continuous running if sensor is fouled by debris, pump reverts to 2.5 minute cycle mode. The NEW Rule-Mate bilge pumps operate using an internal water level sensor.

Auto Sense Intelligence — integral water level sensor controls the pump automatically – it will turn the pump on when the sensor detects water.

When the bilge water level reaches 62mm height the pump will automatically activate, removing water from the bilge. When the water level goes down to 16mm height the pump will automatically shut off until the water level rises again.

Hidden Air Vents in the Body — helps prevent air locking in challenging plumbing installations and helps with the check valve.

A check valve is included in the discharge nozzle to prevent water running back into the bilge. 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. Smaller Footprint — new RuleMate is 2/3 the size of the existing model allows mounting in tighter spaces.

All pumps are the same physical size – 73mm depth x 112mm Height.

The length is 129mm to the end of the threaded discharge nozzle and totals 165mm including the screw-on hose port.

The actual snap-in strainer mounting base footprint is 64mm x 57mm with a slightly oval shape.

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.

The Rule 3 way control panel can be used to control and indicate operation of all Rule bilge pumps and will allow the Rule-Mate pumps to function with a manual over-ride operation feature using the 3rd wire supplied in the wiring harness of the pump. A 3 way switch panel will offer Automatic on, Manual Override On and Off.
