Rule 500 GPH Automatic Bilge Pump
 
 
 
 
In the next generation sensing bilge pumps, the 500 gph S series pump works on the principle of impeller resistance. The pump will turn on every 2-1/2 minutes for about one second to sense for water. If water is present, the pump will sense resistance and continue to run until all water is removed. After that, it will resume checking for water every 2-1/2 minutes. Water is kept in check between 1/8" and 3/8"!!! Great idea when power conservation is needed and as an added benefit, no float switch is needed! All that plus the added benefits of our standard bilge pump: 500 gph should mean 500 gph when the boat is docked or moored 12 volts, not 13.6. Check valve included with hidden air vent to prevent airlocking. true electromagnetic suppression (EMC) a built-in thermal cell that protects the pump and the vessel when things get too hot. These are the smallest automatic pumps available on the market!!!
