What is the pressure output of one stage in a submersible pump impeller?

The pressure output of one stage in a submersible pump impeller is generally understood to be around 9 psi per stage. This is based on the performance characteristics of the impeller design, where each stage typically generates a specific amount of pressure due to the energy imparted to the fluid as it passes through the impeller blades.

The design of these pumps allows for improved efficiency and the capability to lift water from significant depths, with multiple stages creating a cumulative effect on the overall pressure output. Understanding this characteristic is vital for applications that require precise water delivery under varying conditions, such as in irrigation systems or deep well applications.

By knowing that one stage usually outputs around 9 psi, plumbers and technicians can better calculate the total pressure output for a system based on the number of stages in the pump.
