🔍 Key Concepts

• How water behaves on a rotating shaft in a leaking centrifugal pump • The specific function of a shaft seal, lantern ring, drain hole, and water flinger • How bearings can be damaged by water intrusion and what device is placed closest to the bearing to protect it

💭 Think About

• Which of these components is specifically designed to throw or deflect water away from nearby parts when the shaft is spinning? • Which options are mainly for sealing or lubrication around the stuffing box area, and which is for physically redirecting water flow? • Visualize the layout: impeller → stuffing box/seal area → bearing. Which device would you expect to be just ahead of the bearing to keep it dry?

✅ Before You Answer

• Identify which device is primarily meant to deflect water off the shaft rather than seal it tightly or drain it away • Confirm which part is normally located nearest the bearing in typical centrifugal pump construction • Eliminate any choices that are mainly for packing lubrication or static sealing rather than for handling water running along a rotating shaft
