If you want to get more performance for your return pumps, then look no further than the penductor. Also called an eductor, these nifty devices are nothing more than specializes nozzles that afix to the discharge side of the pump. They significantly increase the flow being emitted from the pump, but not by causing the pump to work harder. Instead, penductors induce additional water flow outside of the original steam thanks to their unique design, resulting in far more water movement with little to no increase in energy. It should be noted that not all pumps can utilize these devices as they may not have enough flow or pressure to induce that extra flow.
