🔍 Key Concepts

• Centrifugal pump performance indicators: head pressure, flow rate, efficiency • Mechanical condition indicators: vibration, noise, bearing/shaft wear • Seal and packing condition: packing glands, sleeves, and leakage

💭 Think About

• For each listed condition, ask: does this suggest internal wear or damage that affects pump performance or reliability, or is it a minor/normal issue? • Consider how a healthy centrifugal pump should behave when the discharge valve is gradually closed—what should happen to head pressure and flow? • Think about whether increased vibration and frequent repacking are symptoms that usually lead to scheduled maintenance, or a full overhaul.

✅ Before You Answer

• For each option, decide if it clearly indicates abnormal operation beyond routine adjustment or minor repair. • Mentally separate what can be fixed by simple maintenance (like repacking) from what usually means internal wear requiring an overhaul (impeller, bearings, shaft/sleeve). • Ask yourself if any single listed symptom by itself is enough to justify an overhaul, and then whether having all those symptoms together changes your decision.
