🔍 Key Concepts

• Centrifugal pump stuffing box and packing gland function • How packing rings should be installed and seated one at a time • What causes uneven wear on packing rings near the gland vs. near the impeller

💭 Think About

• Think about what would make only the rings closest to the gland work harder and wear faster than the ones closer to the impeller. • Which procedure during installation or tightening would cause some rings to carry more load or compression than others? • Consider whether the issue is more likely from how the rings are installed or how the gland is tightened later.

✅ Before You Answer

• Identify how proper packing installation distributes pressure evenly across all rings. • Check which choice describes a condition where the outer rings are compressed more than the inner rings. • Eliminate any option that would tend to cause all rings to wear similarly, rather than just those near the gland.
