Which step is NOT part of the start-up procedure for a centrifugal feed water pump?

• A. Close suction valve
• B. Open suction valve
• C. Turn on
• D. Open discharge valve

Answer: (A)

In the start-up procedure for a centrifugal feed water pump, the first essential action is to ensure that the pump is primed and ready to operate. This typically involves opening the suction valve to allow water to enter the pump. By doing this, the pump can create the necessary suction to operate effectively. Closing the suction valve would prevent water from flowing into the pump, which could lead to cavitation, damage, or failure of the pump. Therefore, closing the suction valve is not a part of the appropriate start-up procedure. The subsequent steps usually include turning on the pump and then opening the discharge valve to allow the water to flow out of the system. Properly following this sequence avoids operational issues and ensures that the pump functions efficiently.
