What is the primary purpose of a lantern ring in a pump packing gland?

Explanation:
Lantern rings are used in the stuffing box to carry clean water or sealing fluid into the packing area. Their main job is to distribute that water evenly around the packing rings and the seating area, so the packing is cooled, lubricated, and any debris is washed away. This helps prevent excessive wear and heat buildup and extends the life of the packing. It isn’t a separate seal, nor does it seal the gear housing or reduce noise, so those options don’t fit. The key idea is that the lantern ring improves seat water distribution to the packing.
