We need to select a centrifugal pump with a flow control valve in the discharge line, connected in the other line, which is an another centrifugal pump discharge with a level control valve. What is the best selection criteria (performance curve) for a centrifugal pump where head (and flow both) may vary yet, the pump should not see a 'closed discharge'?
Have an insight or suggestion?

Re: Best selection criteria for a centrifugal pump24 May 2006 at 1:29pmThere is no selection criteria for a pump that needs to vary the flow and head and not experience a closed discharge condition!
It has nothing to do with the pump selection criteria. It is an overall system design and pump selection exercise, particularly so if the pumps are running in parallel.
