Next generation compact submersible 500 GPH electric pump for use as a bilge or bait pump on smaller craft.

This pump is extremely efficient, draws low current and offers high capacity output in a very compact housing, to fit into the smallest available space. 

NON-Automatic pump - requires a Rule float switch to operate automatically.

Please note, using the included check valve will reduce the output flow of the pump.

3 year limited warranty.


  • Fully submersible pump - 500 US gallons per hour - 31 litres per minute.
