ESSUP the original pump info I have that was at 438 gpm. I am 100% sure It was a single phase
Franklin 7.5 hp pump (web Link) . I have since upgraded to a 10hp pump that is normally getting mid 500 with very little head pressure. I am not 100 % sure on the model number as the one the well man gave me was for a 3 phase 10 hp franklin pump. I really will not know for 100% certain on the 10 hp until I pull it one day.
JKB and I had been in a discussion about it over a year ago and he had some more efficient solutions for me if that pump ever fails. In the mean time at less than $500 a year in pumping it would not be cost efficient for me to pull and replace the well pump.
Keep in mind my volume is due to having a tremendous amount of water available and virtually very little head pressure. I get a lot of bang for my buck.
