RE: Gear Pump
Just ask the same question and hopefullly you'll get a sensible answer.
My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way
RE: Gear Pump
at the same time i think that the presence of internal relief valve doesn't involve the assence of PSV on the recirculation line..
in my opinion the second one is a protection for the line, infact is set in function of the line rating.
do you agree?
RE: Gear Pump
The internal or integral relief valve set pressure in the pump is usually determine by the pump vendor to protect the pump
or preventing the motor from overloading due to a closed discharge valve.
In the absence of internal/ integral relief valve,the external PSV must be installed before the discharge valve.
