Discharge pump flow
 

A shipper pump has 2 MOV's at suction and discharge. The Suction valve is open and discharge valve close. the discharge valve will be open when the pump start by sequincing time. Now, WHAT IF THE PUMP START AND THE VALVE NOT OPEN FULLY, IS THERE ANY POSSIBIITY TO TRIP THE PUMP BECUSE THE BACK PRESSURE? IF YES, CAN WE START ANOTHER PUMP AS SUCTION IN SERIES, IS IT WILL EFFECT THE PRESSURE AND PREVENT THE TRIP OF THE FIRST PUMP? THE OTHER PUMP WILL BE AS SUCTION OF FIRFT ONE.
