- I hope you all can help me with what will be simple for a pump expert.

I have a fluid with a 1000 centapoid thickness and want to pump 3 gpm through a 50' 3/4 hose. I need the 3 GPM at 40 PSI at the Nozzel tip to be successful as the nozzel is rated at 3gpm at 40 psi.

I am thinking a diaphragm pump 1" will do the trick but with the thickness I am not sure and need proof.

Thanks for helping me out. Neat site! Jerry, you are welcome.

It has taken me 9 months to get this and I really appreciate your help.

If you provide me your address I’ll send you some Tennessee treats!

is 310 ft of head, if we add 85 ft which is the required pressure (40 psi at 1.08 SG) at the nozzle we get 395 ft or 185 psi taking into account the SG. Don't think you can get that out of a diaphragm pump, you may need a piston pump or perhaps a small peristaltic or lobe pump.
