How to reduce flow rate?

[rmme17]

What is a common way to reduce the flow rate and increase the back pressure on a pump driven by an electric motor? Are flow rate limiting valves a good choice or are there better methods to use? Flow rates in the pipe of aprox. 8 USGPM, 50 psi to 60 psi. If more specific information is needed, let me know. Thanks,

I tend to agree - but remember some posters don't know what to ask or why, therefore I feel we should tolerate this to a point but expect reasonable answers to our " twenty questions" and if not forthcoming just leave it.

Howbout we do one response/answer, and unless there is something significant somebody wants to add, we just leave it alone until there is some indication the OP is still alive.

BigInch - I think that is a reasonable approach for the 1 or 2 line questions which are always short on specifics - however, for the more involved questions posted by those who have put some thought into their problem and give reasonable info' etc - these should be given our assistance as usual.
