I have a wellsaver 52 gallon tank and trying to find size of pump to go with tank, help please!!

You size a pump according to the needs of the system, not on the size of the tank. What size system do you have? Is your tank a pressure or a bladder tank? Regards, Tom

Sizing a pump has more to do with the application of the pump then it does the pressure tank. Is this a shallow well pump or submersible. If it is a shallow well then you need to know how far the pump is pulling water from the supply and the lift involved (distance in height from the water surface to the pump) . If it is a submersible then you need to know the pumping level, the recovery rate of the well and the static level. Size of well casing is important also.
