high Pressure pumping
high Pressure pumping
(OP)
Got a challenge. Need to lift approximately 700 gpm of water approximately 1,300 feet. Looking at different options, intermediate booster pumps, etc.., but I am curios if anyone has experience in lifting water at such a high pressure. Any tips on pumps, piping, etc.

Are we going up a hill or are you down in a well? You can try doing it with one pump if you want, but not suction lift.

A piston or a piston diaphragm pump can do this easily. A piston pump will be the more economic option, if there are not many solids in the water. A positive displacement pump of that size (flow, not pressure) is not cheap but I think cheaper than working with various centrifugals in serial.

I was looking at a multistage centrifugal pump that can give me over 500 psi. But I am a little bit concern about piping, I understand that ANSI #300 should cover it, but what kind of pipes and joints are rated for 550psi and not even thinking about air release valves, water hammer control, etc..
Someone suggested using flexible stainless steel pipe (I am not quite sure if that is a good solution). In any case it would be great to run the entire length of a pipeline without separate booster station.
Thanks again
RE: high Pressure pumping
I suppose you are making reference to one centrifugal, but multistage pump?
RE: high Pressure pumping
Can't you send a (handmade) sketch of your pipeline layout? You are taling about air release valves. That sounds as if your pipeline goes up down.
RE: high Pressure pumping
You can always use steel pipe and welded joints. You can probably find GR Plastic pipe, HDPE, etc. that might work for that pressure. Think I saw that Victalic even works to 300#. Lots of options.
You only need intermediate booster stations if you run out of pressure from pressure drop in a long horizontal run and have to put in another pump, but that might be 40 miles away or something. Depends on your pipeline profile. If its all straight up, do it with one pump.

RE: high Pressure pumping
Someone mentioned HDPE pipe, can you really use them at such high pressures: over 500 psi. My understanding is that ductile iron is not even rated over 350 psi. I feel, if there is HDPE pipe rated for that kind of pressure thatwould be most cost-effective solution
Thanks again for your kind support

Further to the use of HDPE you're right as pressure involved exceeds by far the max allowable pressure.

RE: high Pressure pumping
high-density, high molecular weight PE 3408 polyethylene compound that meets or exceeds ASTM D
3350 cell classification 345464C, and is listed by the Plastic Pipe Institute in PPI TR-4 with HDB ratings
of 1600 psi (11.04 MPa) at 73°F (23°C) and 800 psi (5.52 MPa) at 140°F (60°C).
Maybe. What is a HDB rating?

Page 6 of 8 of the attached paper shows values which leave me a bit puzzled
RE: high Pressure pumping
Now. 45000 feet .... horizontal ... I presume.
You can still do it with one pump if the diameter is right, the pipe material is strong enough and the pump has the pressure capacity. 1460 psig is no problem for steel pipe, or one pump. Just needs more power. You're nowhere near any limits I know of.
