I think I would like to try to irrigate my dads 2.5 acres using a centrifugal pump pulling water out of his well-filled pond. If I can get 50-100 GPM rather than 22 which is what our well gets, I can use less wire, possibly fewer valves, and bigger heads with bigger nozzles. The pond is pretty clean, and the intake will have a filter on it and float elevated within the body of water. I have found centrifugal pumps from $800-$3000 which will provide 60-100 GPM at 50-200 PSI. Can you all give me some "look-out-for's" or reasons to not do this. Also I am looking for a good brand pump or an anticipated approximate price range. Thanks.
