^ What they said.^
Do you know what your head is in that well? (How far down below grade is the water level in the well casing without the pump running.) In my searching for a well pump, that one that you have isn't very effecient.
See if 3-phase is available at your place. If it is, that's an option for a different pump. My well pump is only 3/4 or 1 hp and I can pump more than half of what you are pumping. My well is 66' deep, and the head is 13'.
I'm looking at a 5 hp 3-phase pump that can pump 320 gpm......
I'm thinking static water level is 30 feet. The household well is 16 feet.
