Rule Fully Automatic Bilge Pumps are rated from 500 to 3,700 gph. There is no float switch to go wrong as the pump utilizes current draw differential technology for operation.

  • 12 volt, Fully Automatic, pumps when water is present
  • No external floats or switches
  • Completely submersible, rust and corrosion proof
  • Water cooled motor
  • Snap-off strainer for easy cleaning
  • These models all have three wires; power, ground and an indicator wire which may be connected to a light
    Features of the Automatic Series:
  • Turns on every 2-1/2 minutes to sense for water
  • Senses by measuring amp draw (power consumption) caused by the work the pump does when moving water
  • When no water is present, there is less amp draw (work being done) and the pump then shuts off
  • It then waits and recycles itself after 2-1/2 minutes

NOTE - ALL Rule Automatic Bilge Pumps listed on this page are 12 volt DC

All Rule pumps work on the principle of centrifugal force. They must be submerged in the water or be below the water source. Bilge pumps must be mounted in lowest possible point in the bilge. Livewell pumps must be below the waterline. They only push water; they do NOT pull water.
