🔍 Key Concepts

• Difference between contact surfaces in a packed stuffing box vs. a mechanical seal • How wear occurs and is corrected in packing vs. mechanical seals • What happens operationally when packing fails compared to when a mechanical seal fails

💭 Think About

• Think about how a traditional stuffing box with packing is adjusted over time as it wears. What can the engineer physically do while the pump is running? • Consider a mechanical seal: if it starts leaking badly, what practical options does the watchstander have without shutting down the pump? • Look at each choice and ask: does this describe something that is always true for both fresh water and fuel/service pumps on ships, or does it sound like an oversimplification?

✅ Before You Answer

• For each option, visualize the orientation of the sealing faces relative to the shaft for both packing and a mechanical seal. • Check which component – packing or mechanical seal – can be tightened/adjusted in service to slow a leak versus which generally requires replacement. • Be careful with absolute statements like "do not require cooling" or "are not subject to wear" – verify whether that could realistically be true for any moving seal.
