Nozzle PSI required?

[Geo-George]

Really need too know the PSI required to operate a 3" nozzle with a 1 1/2" pressure line intake.
Volume is not an issue, have plenty of that, just need the PSI.
Is there a table available showing specs for different size nozzles?

Geo i really dont know what psi youll need for your nozzel with the info you gave. i would contact the manufactor and ask them.

O.K., let me put it this way,...
What would be the volume, GPM, required for efficiant operation?
It's Sunday and the manufacturer isn't answering.
I can't find ANY specs for pump output.
What is the pump output required?
I need to know GPM or PSI.

well according to the Keene website (http://keeneeng.com) they have a P180 pump thatll putout 300GPM (this is what i have on my 4 inch dredge) and used it on my 3 inch pressure nozzel at times.and they show a P100 pump thatll give you 150 GPM (id use this as a very minimum) and nothing inbetween. it depends on what your using this for and lift you need to pump the water to(uphill) or just moveing the water to a device through your p.nozzel. so depending on the engine you have to pump the water up hill (lift/head preasure) id go with the bigger of the two to keep from limiting myself for another site. now this is just Keenes info, Proline has their pumps as well as others.

Thanks Russ!
That gives me a starting point, 150 gpm minimum.
Now I can do some math and figure out what I've got vs. need.

[russau]

not a problem!

The PSI you'll need should be 45 to 50 PSI minimum, more would be that much better, my 2 1/2 H.P Honda with a P-90 for my 2" highbanker puts out around 75 PSI.

Keene is in the process of building this for production guys in case you haven't heard. A lot of our guys are trying to work out the spec's. also. Nice part is no permit required!

Mark Keene says,
"You need about 150 gpm at 30 psi if you want good performance."

I'm gonna go for 150 gpm at 30 psi as the minimum, for "good performance".
I'd like to come in better than "good", say 240 gpm at 57 psi.

I have done so much, with so little, for so long, that I am now qualified to do anything with nothing.
Now, I just have to find the time to put the dang thing together.
