    OP wants big sprinklers and big flow to run from a centrifugal pump, and stated as such. Deal with it. Show us the way.

    The DHJ provides 81 GPM at 60 PSI discharge pressure with a 5 foot suction lift. Are you saying this is not enough to irrigate 2.5 acres?

    The DHG provides 30 GPM with 5 foot suction lift at 50 PSI. Are you also saying you can't irrigate 2.5 acres with this pump? You don't know the first thing about how this system will be designed, elevation changes, system pressure loss, etc...... and yet you can definitively state there is no centrifugal pump that will work. You are a real piece of work bud.

    OP wants 50 gpm minimum, and stated as such. He wants "big heads" ~ make it happen with a centrifugal pump.

    OP says what he wants and you can only weasel the numbers, and finally submit that he needs a 5HP pump? Weak. Very weak.

    I responded to the idea with a flat statement that there was absolutely no practical (that also means economical) way to achieve his posted desires, and you had to object to that statement, even without anything to back your position.

    Just for shits and grins .... since you are so hung up on the word "big" ..... using the DHJ you could run two Nelson 75 series "big" guns with a 0.45" nozzle at 35 PSI nozzle pressure (32 GPM) and a 154 foot radius. Is that a big enough sprinkler for you boots?

    Show us the popup heads that fit the requirements. Take your time.

    What's the matter boots ..... having a problem with the numbers I posted on the Falcon? Are you saying you can't use one of the other pumps you posted to irrigate 2.5 acres using the Falcon rotors?

    I see .... so now we have a price limit? You are the one who is hung up on "big" heads that are silly expensive.

    Your answer, as usual, was use a jet pump, which doesn't even come close to filling the OP's flow desires. Again .... thanks for playing boots.

    Oh I see .... "big" isn't good enough .... but it must be a "big" pop-up. Already posted the numbers on the Falcon, are you blind? Did you stick your boot in your mouth again?

    You simply have no (rational) response to the flat statement that the OP's desires can't be met with a centrifugal. It stands as truth.
