The invention discloses an energy-saving rate determining method by applying the reproducing and repairing technology to a pump. The method includes collecting rotating speed, flow and running power of the pump before and after implementing of the reproducing and repairing technology, respectively acquiring a proportional ratio of the pump after changing of the rotating speed and a proportional ratio of the pump after changing of the flow by changing the rotating speed and the flow according to a proportion law of the pump, judging whether the proportional ratios satisfy the proportion law or not, correcting the running power of the pump according to the proportion ratio after changing of the rotating speed to correct the running power of the pump after implementing of the reproducing and repairing technology to be the running power of the pump at the corresponding rotating speed during testing before implementing, and acquiring an energy-saving rate mu, equaling to (1-P correction/P before)100%, of the pump
