If a centrifugal pump is started with the discharge valve open too far and with a low discharge pressure, the liquid in the suction line may accelerate at a rate that causes the suction pressure to drop below vapor pressure.
As energy costs rise and energy efficiency becomes more important in operating pumping systems.
Power pump NPSH tests are performed by holding pump speed and discharge pressure constant and varying the NPSH available in the system.
Do pumps require less NPSH on hydrocarbons?
