    Default turbodraft

    for you guys that use turbodraft have any of you used them in with drafting question is how much water would you get if you use a 1000 gpm pump at draft and hooked up your turbodraft at the same time would you be near 1500 or less

    The standard turbodraft you see marketed is, roughly, rated at 200gpm in/800gpm out.

    Was at a factory demo 2 weeks ago, numbers looked a little on the low side but close to what they said (and close enough the difference could have calibration of the pitot gauges or other factors).

    So...

    1000gpm pumper at draft gives you 1000gpm (assuming nothing else is restricting that)

    200gpm has to go to the TurboDraft so you have net 800gpm from the hard suction.

    200gpm goes down the TurboDraft. At 50' of 2.5" supply and 50" of 5" return, you'd expect 800+ gallons coming back gross. That would be consistent with what I saw.

    800 from draft
    800 from TurboDraft
    1600 gpms -- numbers work.

    Would work well to fill tankers. I'm not sure on how the hydraulics all interact if you were feeding the 800gpm TurboDraft supply into your steamer to combine with the water from draft to feed a laid line.

    -----------
    Now, if you weren't drafting for your supply and just using the turbodraft, you have deduct the 200gpm from your total to get the net. 800gpm - 200gpm = 600gpm net.

    A Turbo Draft can take a while to deploy. Our our double laid 5 inch and 2 1/2" preconected turbo draft at 150 feet takes one guy almost 45 seconds to deploy, get water and get deck gun in operation. Drafting takes about 1/3 that. However in the scheme you describe I'd use two or three turbo drafts and flow 2400 gpm. With a big and a small one we seem to be limited to 2800 gpm in 3 minutes with a 1000 gpm pumper.

    Doesn't the amount of flow depend on the size of the hose, the length of the hose, and the amount of lift?

    What is cool with the turbodraft is that it allows me to beat the laws of nature, you can draft more than 30 feet of lift.

    Hey!, you can`t fool mother nature, the Turbodraft (or any other venturi) works on pressure, not on suction.

    Has anyone used the other makes,/models of venturi assisted drafting equipment?, I think the only special about Turbodraft is marketing, you know...presenting an old artifact as a "new, revolutionary achievement for the humankind".

    The tipical $300, venturi assisted low level strainers must bring similar performances, but everybody seems to use them at only 50 psi, not at the 175-200 psi that Turbodrafts marketeers recomends.

    If someone will do it (with the tipical strainers), please inform to us the final gpm.

    Regards.

    I don't know that adding a TurboDraft would increase water output.

    The 1,000 GPM coming in from the hard suction relies on a fairly significant vacuum to allow atmospheric pressure to push the water up and in.

    The TurboDraft pushes water to you under slight pressure. By adding the TurboDraft, it would raise the pressure slightly inside the intake, and you would lose the ability to create a strong vacuum, thus you would lose the 1,000 GPM from the hard suction hose.

    On the flip side, if you create a hard vacuum to use the suction hose, it would collapse the soft intake hose from the TurboDraft.

    It's just theory until someone tries it.
