    How much water would you need for a 3" dredge? I'm asking about gallons per minute. 50 gpm or 60 or 70 or 100 or more?

    Jim,

    Check out Keene Engineering .com
    Look at their 3" dredge, figure out what pump/motor setup they use
    Go from there
    Trash pumps dont do it for a jet type dredge
    My guess is more

    Went to their site and they don't have specs on their pumps. Don't know why . Pretty poor marketing if you ask me.

    on a Keene 3" dredge they uses a 5 hp B/S engine and a P180 pump it has 300 G.P.M
    bigger the engine the more P.S.I you get the higher the P.S.I more volume and more gold

    Doc at Gold Hog has some good videos explaining volume/pressure /flow rates, and how they all affect each other. One essential video is "Proportional Force". Some segments specifically refer to dredges.
