Hi guys-
I think I've narrowed down my pump choice, but I just want to pass it by more experienced minds, see if I'm missing anything, and ask a question.
Well depth 400', produces 30 gpm no sand or grit, static level 290' below head, pumping to a cistern not a pressure tank, vertical rise to cistern from head 35', total vertical rise 325'.
Total length of pipe from pump to cistern 660', with 1" pipe, about 6 fittings, so total dynamic head 360 ft. or so.
Ive been looking at Flint and Walling 1 horsepower pumps, either 5 or 7 gpm. Here's the charts:

So first, does it look like I'm in the ball park? Missing something?
Second, I'd prefer the 7 gpm so I'm using my generator less to fill the cistern. What I'm wondering is, would the 5gm pump probably last longer? since it is being strained less-
Thanks
