🔍 Key Concepts

• Proper adjustment of stuffing box packing on a centrifugal pump • Desired leakage rate from a properly packed stuffing box • Effect of over‑tightening vs gradual tightening on packing life and shaft sleeve wear

💭 Think About

• Think about what happens to packing and the shaft sleeve if the gland nuts are fully tightened right away before the pump is running. • Consider whether packing should be adjusted quickly in one step, or gradually over time as the pump reaches normal operating conditions. • Ask yourself how a small, controlled leakage from the stuffing box affects cooling and lubrication of the packing.

✅ Before You Answer

• Verify whether some leakage is desirable from a stuffing box, or if it should be completely dry. • Check which option describes even, gradual adjustment over time rather than a one-time heavy tightening. • Eliminate any choice that would likely cause excessive friction, overheating, or rapid packing wear.
