    Pump Psi

    Good morning can any of you guys tell me what psi a p100 or p180 puts out.I do not need the gpm but the psi pressure I am assembling a new 2.5 dredge that I got parts for dirt cheap and wondering if the pump I accuired for free will work.I got 175gpm at 35psi.If Hoser John can help that would be great he seams to know about everything dredge related.

    the stats you posted for the pump you got should work just fine for a 2 1/2 !but it may have a problem if you try to dredge to deep! look up your pumps head preasure to see what itll do!

    For a little ol' 2,5 it should work fine but if trash style or clear water style might be close as not close tolerance and mfgr put out bookoo bs. Make sure about GPM vs GPH as folks make that mistake quite a bit starting out. Lotza luck-John

    I use the P180 on my 4 inch dredge so the smaller one should work for 2.5 ??

    HUMMMM? might be kinda marginal at that depth! youll probly end up with lots of plugups if you suck very much material at one time!

    Thanx russau I will give it a try this weekend it was free so nothing lost if it fails the 5hp briggs is new so if nothing else I will put a p180 on it and call it done.I tried my little pump from my 2 in it is a 2.5hp trash pump.Using a suction nozzle it did ok but had to let it gulp air now and then or I would get plugups.I am hoping the jet will improve the suction.

    No Hoser not a Gold King it is not a dredge pump I think it was a sprayer pump or a fire pump I thank you and russau for your help

    I too just acquired an amost free (case of beer) pump. Not sure what I'll do with it. It's a Waterous PB18-2515 max discharge 200 gpm, ran off an 18hp B&S. Off hand I forgot the pressure rating, but it's almost twice what an equivlent keene or proline has. The motor is shot but I know the pump should be fine. The application is about the same as your pump basspro, clear water fire booster pump. I think I'll most likely salvage the pump and sell it, to help fund a proline pump.
    Whats interesting is how much pressure this thing has around 175 gpm @ 90 psi (I think) at this pressure wouldnt a guy have to move the jets on the flair closer to the nozzle. Im guessing the water would almost spray out of your flare with that much pressure I dont have much experience dredging so bear with me. This part of the reason I might just sell the pump and go with something I know works. Might take too much tinkering to get it to work perfectly. Id rather have a smaller pump/motor with just as much suction capability... Andy
