🔍 Key Concepts

• Stuffing box purpose and how it prevents leakage around a shaft • Function of a lantern ring (also called a seal cage ring) and why sealing water is supplied • Why even, proper packing and cooling/lubrication are critical to avoid shaft and packing damage

💭 Think About

• Which option would help ensure that cooling/lubrication water can reach the lantern ring and packing as designed? • Which choices, if taken literally, could lead to overheating, excessive leakage, or damage to the shaft or packing? • Think about whether you normally re‑use some packing or renew all rings when you already have the stuffing box apart.

✅ Before You Answer

• Verify how a lantern ring is positioned relative to the sealing water inlet and adjacent packing rings. • Consider whether blocking sealing water or using lapping compound inside a stuffing box would be safe for the shaft and packing. • Ask yourself: when the gland is opened and packing removed, is it standard good practice to renew all rings or only some of them?
