I have looked at Dolphin pumps, but cannot find the info on pressure settings.
Yes they do and I went back to your original question to answer it.
The pump you are looking for is a centrifugal pump with an adjustable pressure relief valve that is piped back to the tank.
An alternative to the pressure relief valve would be a globe valve that you can open and close to adjust the pressure going to the field.
You want to make sure you dont boil the water coming out of the pump due to cavitation so this water has to go somewhere.
On the good side it can warm the water up for you.
Steps pick out pump.
Put valve on down stream side of pump.
Put gauge in line after pump.
Adjust valve by way of gauge reading.
DO NOT over estimate what pump sized you need bigger is not better.
This will only wear out the pump due to cavitation.
Your well pumps can keep the tank filled.
