PSV on pump inlet/outlet
PSV on pump inlet/outlet
(OP)
Hello there, first time here.
I have a doubt concerning PSV between pump outlet/inlet.
The pump is centrifugal, built according to API 610. The fluid is gasoline. The flowrate is 250m3/h and pressure on the outlet is around 10barg.
Should I put a PSV, connect outlet to inlet, opening to the inlet, for recirculation purposes? Or is the pump prepare for that, in case of obstruction or valve closing on the outlet side? For what I saw so far, there are only small Thermal relief valves. Thanks!!

RE: PSV on pump inlet/outlet
On the case of a centrifugal pump, if you pump against close valves, the pressure only goes so high according to the project parameters. If the pumps gives 10barg at the outlet, and if you a close a valve, the pressure will not go higher then this. Is this true?
After a while the liquid will begin to heat up because of the movement, but apart from that, the pressure will not rise. Am I thinking correct?
Thanks!
