  1. I didn’t realize that three phase power configurations on well pumps uses overlapping waves to provide constant power. My sister is having a home built for her family in the hills. Hopefully, she can use this info to choose a set up that can supply her family with constant water. Thanks!

  2. One of the water pumps in the city broke a week ago and it got me curious about them! I didn’t know there were different power phases for pumps before. That is really cool that the most common power phases are single and three-phase! Thank you for all the information!

    Hi We have single phase power available but we want to use a 3 phase in the pump. Is this possible. What is the life span of a 240 vs a 3 phase pump?
    Thank you

      Miguel,

      Thank you for your question. It is not possible to operate a three phase motor on single phase power without a piece of equipment called a phase converter. Digital phase converters are commonly added to variable frequency drives (VFD), and can be purchased from most motor shops or local electrical contractors. Keep in mind that if you are using a variable frequency drive, you need to either purchase a motor with a shaft grounding ring, or install a shaft grounding ring on your existing motor to insulate the bearings from stray voltage.

      Here are a couple of sites to check our for more information.
