How do you size a well pump?

A key to selecting the right size pump is to figure the gallons per minute of water required at peak periods. A pump should be selected to meet normal peak demand for the household, rather than average use. There are two common methods for sizing a residential pump system that give similar results.

Can I plug my well pump into a generator?

Unfortunately no. Unlike many of your appliances that plug into an electrical outlet, your well pump is hard-wired into your home's electrical circuits. Disconnecting these wires from your electrical panel during an outage and attempting to connect them to a portable generator, is potentially dangerous.Jan 9, 2017

What is the label on a submersible pump?

This label has information like how many horsepower or kilowatts the motor is rated for, how many amps the motor is expected to use and the voltage that the pump needs to run properly. Finding this label on the above ground pump is usually the work of just a few seconds, but what about the submersible pump? It is often located hundreds of feet in the ground!

Why do you need a larger breaker for a generator?

This is not a typo or mistake! The circuit breaker needs to be significantly larger because the amount of current/power used to start the pump spinning/pumping is very high. Once the pump has finished accelerating to speed, the current and power usage will drop down to the normal range. For this same reason you need to size the generator for the starting current (circuit breaker size) and not the running current of the pump! Check out more information on page 5 of the AIM Manual or check out our blog if you need to size a generator for your submersible well pump.
