The average life expectancy is 10 to 15 years for a residential 3-wire and 8 to 13 years for a residential 2-wire well pump. Life expectancy of the pump depends on many different factors, some of which are the quality of the pump, how often the pump has to run, and the electrical supply to the pump. Here is a list of some of the factors that determine life expectancy.Avoid upthrust and downthrust. When there is lower pressure (low head) the impellers will “float” up and wear on the diffusers...

Most 4” submersible well pump motors used in residential applications are available in 2-wire or 3-wire configurations. The ground wire is not counted in the terminology. 2-wire motors have two black and a green wire. ---- ---- ---- 3-wire motors have a black, red, yellow, and a green wire. ---- ---- ---- ---- The starting components for a 3-wire motor, including start capacitors, run capacitors, relays, and thermal overloads are contained in a control box above ground. The starting components...

Submersible well pumps are multistage centrifugal pumps. Each stage consists of a stationary diffuser and a rotating impeller. Submersible well pumps usually work in a vertical position and the impellers are designed to “float” up and down between the diffusers. What is Upthrust? When there is less pressure (low head) the impellers will “float” up and wear on the diffusers above. In an upthrust position there is a higher volume of water being pumped against lower pressure. As an example, this...
