Q

Excessive wear on a centrifugal pump shaft sleeve will __________.

🔍 Key Concepts

• Function of a shaft sleeve in a centrifugal pump and what it protects • How a packing gland and stuffing box control leakage along the shaft • Difference between leakage along the shaft and internal leakage between pump stages

💭 Think About

• Ask yourself: What part of the pump does the shaft sleeve actually contact, and what happens if that contact surface becomes worn? • Which of the listed problems is most directly related to sealing around the shaft, rather than to internal stage-to-stage flow or casing issues? • If the sleeve wears down, does it more likely change shaft balance/alignment, or does it affect how well the packing can seal against the shaft area?

✅ Before You Answer

• Identify which option is specifically about leakage where the shaft passes through the casing (at the packing gland). • Eliminate any options that mainly involve internal flow paths between stages, which are not the primary job of the shaft sleeve. • Confirm which choice best matches a sealing failure at the stuffing box/packing area, rather than vibration or general casing damage.
