In response to the problems of pumps, some domestic manufacturers put their energy on the protection system of the development pump: automatically alarm or cut off the power when the pump runs abnormally. Although this method can play a certain effect, and this protection is also necessary, this is not the fundamental method to solve the problem. We also need to focus on improving the performance of the pump and fundamentally solve the problem.

In addition, the development of the product must be fully considered to make environmental problems, so that the research and development products are more energy -saving and environmentally friendly. In summary, the problem that the submersible sewage pump needs to solve in the future is to improve the reliability of use, can adapt to a variety of working environments, optimize its structural design, and further improve the performance of the pump.
