🔍 Key Concepts

• Discharge pressure vs. flow rate in a centrifugal pump system • How a failed coupling on a close-coupled pump affects shaft rotation and pump performance • What a single packing gland bolt does and how its failure changes leakage vs. pressure

💭 Think About

• If the coupling on a close-coupled pump fails, what happens to the transfer of power from the motor to the pump impeller? Would the pump still be able to build and maintain pressure? • What is the primary function of packing and packing gland bolts? Does one fractured bolt typically stop a pump from developing discharge pressure, or does it usually affect something else (for example, leakage)? • Between total loss of drive and a minor change in sealing, which condition is more directly related to the pump’s ability to maintain the necessary discharge pressure?

✅ Before You Answer

• Focus on whether each fault would cause a loss of pump rotation / impeller speed versus just an increase in leakage • Consider whether a single failed packing gland bolt would normally be enough to reduce system discharge pressure below requirements, or if the pump can still develop pressure while leaking • Verify that you’re distinguishing between inability to maintain pressure and excessive leakage when judging each statement (I and II)
