thread407-264259: high Pressure pumping
On 2 Feb 10 "vodeni" posted a question regarding high pressure pumping and pipig. I have a higher pressure and a lot higher volume of water to move in a pumping/storage case. Could "vodeni" tell me what pump he ended up using? Thanks

Given that vodeni hasn't logged in since that time, you may receive some helpful suggestions from others if you provided more detail about your application.

We´re working on a pumping/storage feasibility study and have no experience in such endeavor. It´s necessary to move 270,000 gpm a height of 1050ft with steel pipes 7,300ft long. We think it´d be necessary to split the flow in two pipes using pumps capable of moving 150,000gpm ea. Also to use multistage pumps. We suspect it´d be necessary to use 20 stages of 60ft ea which could be four pumps of 5 stages or five pumps of 4 stages. Total eight pumps of 5 stages ea, or ten pumps of 4 stages ea. Do you know of any manufacturer of multistage pumps with a digital catalog that we could consult so we can find out the size of such pumps?
More importantly, How would you, or any one else, do it?
RE: civil/environmental
To put it into perspective you are looking at something like an installed power requirement of 75,000 Kw.

Be careful with selection programs which are provided by pump manufacturers. They cannot be anything else than just guide you in some useful direction. They cannot substitute engineering work.

The most useful catalog, for us, was the KSB´s.
We´ll surely look at the Northfield Mtn. statistics.
