Analyzing Potential Overpressuring by a Pump
Analyzing Potential Overpressuring by a Pump
(OP)
Hi,
I've been asked to review if a particular pump can overpressure a piping system. The piping system is 300# class and the pumps are centrifugal type pumping anhydrous ammonia. What are the different things I need to look at? Is it just shut-off head? Or do I have to look at the pump curve.
New to pumps here, thanks for the help.

The suction is coming from a tank, so I can get that information pretty easily. I do not have a pump curve on the pump. All I have at this moment is the shut-off head (someone told me). Thanks again.

Note that if your facility falls under OSHA PSM requirements, you must have this information to document that this calculation (blocked-in) was checked against the PSV sizing.
