The relationship between the pump shaft power and the motor power is complex and close. In the process of pump selection and application, it is necessary to comprehensively consider multiple factors to ensure the normal operation and high efficiency of the pump system.

The hardness standard of the submersible pump shaft is the result of comprehensive consideration of multiple factors. In practical applications, it is necessary to determine the appropriate hardness range based on specific materials, heat treatment processes, and working environment. At the same time, regular inspection and maintenance are also required to ensure the performance and life of the submersible pump shaft.
