I have a question regarding reducers near the pump suction and discharge nozzles for a centrifugal pump for flushing water. The line size is 1 in. and the discharge nozzle size in 3/4 in. The expander is 3/4 in. x 1 in. Should it be near the pump discharge nozzle, i.e. located immediate to the flange, or it can be installed after a length of approximately 1 m? It is my understanding that to reduce the pressure drop in the line, the expander to be located near the pump flange.
Have an insight or suggestion?

22 March 2007 at 1:29pmA discharge increaser (from 3/4 in. to 1 in.) should ideally be located on the 3/4 in. pump discharge nozzle. Most importantly, it must be positioned before any valves. Further details can be attained from an article on my website www.practicalpumping.com/articles.
