In the case of a discharge manifold of a system of pumps in parallel (a total of five centrifugal pumps in the present case), must the outlet piping to the process be positioned after the last pump or can it start immediately before the last pump? By adopting the last arrangement, would there be loss in the flow capacity, some turbulence, or even loss of energy or a possible unbalancing of one or more pumps?
Have an insight or suggestion?

Re: What is the best way to arrange a discharge header?29 April 2010 at 1:29pmIt would seem evident that the best way to arrange a discharge header would be to ensure that the flow through that header would be in the same direction from all pumps. Otherwise, as you suspect, there will be severe disruption in the flow pattern that may find its way back into the discharge of one or more of the pumps, causing vibration difficulties.
