🔍 Key Concepts

• Mechanical seals vs. packing glands and where leakage normally shows up • How a shaft o-ring functions in sealing between shaft and rotating parts • Typical effects of starting a centrifugal pump with suction or discharge valves closed

💭 Think About

• Think about which option is directly related to the physical sealing surfaces where the leak is observed. • Ask yourself: which options would more likely cause performance problems (no flow, overheating, cavitation) instead of an immediate visible leak at the seal? • Consider what happens inside the seal if an internal sealing component is omitted during reassembly.

✅ Before You Answer

• Identify which choices specifically involve seal components rather than operating conditions. • Distinguish between symptoms of misoperation (like no flow or pump damage) and symptoms of improper assembly (like immediate leakage). • Verify in your pump knowledge which condition would most logically cause water at the mechanical seal area right after start-up.
