Dear Sirs,
I'm process engineer.
I would like to ask about pump shut off pressure at pump suction block valve.
In case of installing one running pump and one standby pump,
because pump discharge lines are connected each other, pump discharge pressure could be transferred to suction block valve of standby pump. Refer to case A in attahced file.
In case of installing only one running pump,
I'm not sure if pump shut off pressure should be applied to suction block valve. Please refer to case B in attached drawing.
Is it possible that shut off pressure could be transferred to all blocked section ?
Shut off pressure means maximum pressure in restriced section when flow is blocked.
I'm wondering whether all blocked section will have maximum pressure during pump shut off running.
Please share any experience regarding application of pump shut off pressure to pump suction block valve.
