Rule 500 12V Manual Bilge Pump

This compact submersible 31LPM (500 GPH) 12V Manual Bilge Pump is mainly used as a bilge or bait pump but can be used as a water drainage pump where normal 240V power is not available.

The 12V Manual Bilge Pump is a totally submersible pump with water cooled, ignition protected motor, stainless steel shaft and snap-off strainer base is extremely efficient, draws low current and offers high capacity output in a very compact housing, to fit into the smallest available space.

As this is a Manual Rule Bilge Pump, it requires a Rule float switch to operate automatically.
