It can be done. If this is something like a clarifier or package treatment unit then I'm guessing the connection will be made less than 10 feet below the water line.
I'd only connect via flange if the connection is to be made above ground level.
For a buried connection a flange is too rigid...
Referring to the pump characteristic curve, running the second pump shifts the operating point to the left, and lowing your NPSHr and reducing tendency for cavitation.
Is this a new problem? Could it be that you have an obstruction in the suction line, like a partially closed valve or blocked...
Reduce headlosses in the suction piping as much as possible. Its normal for suction piping to have a larger diameter than the discharge piping in order to reduce headloss. The diameter should be selected based on maintaining an acceptable velocity -- don't provide a 4" dia header just because...
Thank you for your reply Pierreick. I've seen sand filters used for solids control in pipelines before, and this is certainly something to consider.
In your opinion what sorts of issues might we see if no pretreatment (like filtration) is provided?
Hi 1503-44, thank you for your response.
Due to the nature of the industrial use, downtime of the system is inevitable. There will be stagnant periods.
Using the tanks in the system for sedimentation is an interesting idea. In any case sediments that do fall out in the tanks will need to be...
What type of package plant do you have in mind? I had a good experience installing the SBR system provided by Acqua Aerobic. That was a 50,000 GPD system for a community similar to an RV park.
Good morning to everyone from a long time lurker and first time poster.
I’m working on a design to pump water from a lake for industrial use in a mountainous region, spanning a few dozen miles. The distribution system consists of a long main with branches leading to each point of use. The...
