Some more details:
Each pump duty point is 5.0m³/s at 90m.
Each pump has a 1400mm dia vertical riser combining at ground level into an expanding manifold (2.8m dia at widest point).
The pressure in the manifold is very low (~2-3m above sofit)
We are in the process of doing a surge analysis at...
Thanks for the replies.
Re: Stanier's point of 'do we need pump control valves?'
We have a deep shaft pump station with high flows & high heads (we have a total of 10 pumps - each at 5m³/s).
PCV's (and generally ball valves) seem to be a common solution on similar installations, however on...
Hello,
I require a pump control valve for a large pumping station, pumping unscreened sewage.
The valve would be normally used for controlled pump start-up and shut-down against the closed valve, opening/closing at a controlled rate to prevent excess pressure surge.
Very occasional throttling...
