🔍 Key Concepts

• Centrifugal pump construction – know the location and purpose of the packing gland, bearing housing, and shaft sleeve • How leakage is controlled or directed around the stuffing box area • The difference between parts that seal, parts that protect the shaft, and parts that deflect/sling water away

💭 Think About

• Which component is specifically intended to prevent water that escapes the packing from reaching and damaging the bearings? • Think about where each part is located in relation to the bearing housing – which one actually affects water outside the stuffing box rather than inside it? • Which option’s main job is to change the direction or path of leaking water rather than to seal it or protect the shaft surface?

✅ Before You Answer

• Identify which option is mainly a sealing component inside the stuffing box (not the right function here). • Identify which option primarily protects the shaft from wear caused by packing (not about directing leakage away from bearings). • Identify which option is designed to deflect/sling water away from adjacent components, especially the bearing housing.
