For self-priming centrifugal pump problems and some domestic manufacturers to focus on the development of pump protection system: automatic alarm or cut off power supply when the pump is running sewage exception occurs. While this approach can play a certain effect, but such protection is necessary, but this is not the fundamental way to solve the problem, we need to focus on improving the performance of the pump, a fundamental solution to the problem.
In addition, product development also fully take into account environmental problems, so research and development of products are more energy efficient and environmentally friendly.
In summary, the next problem of submersible sewage pump to be solved is to improve the reliability, and can adapt to a variety of work environments, optimizing the structure design, to further improve the self-priming centrifugal pump performance.
