    Or should I say how expensive? This is my own yard, I am pumping out of a dug out and I have a lot of ground to irrigate. I need to pump 300' then branch off to my manifolds.
    What is my best method here? Do i need a booster pump?

    I just bought the place in october. There is no irrigation there yet. Hell there is no sod yet either. I have installed many irrigation systems, but never with a pump as my source. Here is what i am working with:

    The linear distance is not the problem, the important distance is the vertical lift. What is the elevation change from the water level to the highest point on the property? Pick a pump that delivers the correct flow (GPM) at this head hight in feet plus 95 ft (95 ft = 40 psi).

    Be sure to put the pump as close to the water source as possible, pumps are made to push water not pull it.

    I do plan on placing the pump right near the dug out. I am guessing it will have to draw from 15-20', and there is no elevation change.

    Any reccomendations on pumps?

    Oh please. Jet pumps can give you much more pressure. If it's 40 psi at the heads that's wanted, a centrifugal pump won't deliver it very efficiently. Now if it's about pumping the most water with the least expense, a straight centrifugal beats a jet, but not at higher pressures.
