Artisi, thanks! Boiling liquid is at the vapor pressure, so I just think about it that way. Probably isn't correct. Cavitation is when it goes from vapor, back into liquid. It carries a huge amount of spot forces on the impeller. There is suction cavitation and discharge cavitation. Different...
Thanks for the tips Steve!
That is the plan. A ValMatic discharge check valve on the second staged pump. At that lift, casing pressure ratings do become important. Not to mention damage from hammer, like you mentioned. In this case, I will not be getting hammered... perhaps later.
The PAH10...
FYI, we're going with a sub at the bottom (turns out they already have a Flygt sub in place for the low pump), and a centrifugal skid-based GR Prime-Aire+ series pump at 100' elevation. at 200' elevation like the engineer designed, there isn't enough suction pressure to feed pump 2. At 100'...
Thanks guys!
I'm pretty comfortable with doing all of the system analysis and system curves, etc. I have created a system curve. My program is pretty sweet, haha! The question is really asking if anyone has run them in series before. I don't expect anyone has. The chances are very low, but I...
Just posted this in another forum. I think this is the right one...
I'd like to ask if anyone here has staged a Gorman-Rupp S-Series S8D1-E275 in series?
We don't recommend it here in Canada and I'm wondering if anyone has tried it and the result. We have an open pit mine, lifting a total of...
