Rule RM500B Rule-Mate 500 GPH Bilge Pump
The eco-friendly Rule Mate is a fully automated bilge pump featuring a solid state water sensing technology to eliminate a separate float switch.
The sensor's unique "field effect" technology is eco-friendly because straight motor oil in the bilge will not turn on the pump.
Pump turns on when the water level reaches approximately 2-1/2" and shuts off at 5/8".
It has built-in programming that can sense when the pump is running but not pumping water to protect the pump, vessel, and the vessel's batteries.
Includes a straight 3/4" hose fitting, a snap-on strainer for easy cleaning and an anti-fouling impeller.
3-Year limited warranty.
