![]() ![]() This will lead to premature packing failure. If this happens, the ability to protect, cool, and properly lubricate the packing is greatly diminished. Low-quality plastic material options will soften and melt much more quickly and easily over time. Using lantern rings that are made from the right kind of quality material is critical. The Ideal Material: PTFE vs PEEK for Lantern Rings Without the lantern ring to provide protection, ventilation, and lubrication, the packing will not function properly. However, the lantern ring is just as important as the packing. Primarily in a stuffing box, teams focus on the packing and which style to use. ![]() Many times, end users overlook lantern rings within the system because they do not perform the sealing function. A lantern ring installed between compression packing rings Ultimately, this increases the lifespan of the whole system long term. Placing a lantern ring between packing rings extends the life of the packing, the stuffing box, and the shaft. Heat increases wear that could shorten the life of the packing and the shaft. It is a crucial element, because packing tends to generate heat. In these three applications, lantern rings are only used in conjunction with packing. In addition, lubrication helps reduce wear of the machine parts and the amount of excess heat generated within the system.Īn example of a lantern ring with a high-performance plastic bushing The fluid entering the lantern ring lubricates the packing. Lubrication - Another main function of the lantern ring is to facilitate lubrication.This keeps the system from being completely closed off. Lantern rings provide an opening and assist cooling in the stuffing box. These structures allow buildings to breathe. Outlet for cooling - Lantern is also an architectural design term for a structure on top of a roof or in an attic that allows for ventilation.If the material that is being pumped or any other foreign matter enters the stuffing box, it could destroy the packing or damage the shaft or stuffing box. Lantern rings help protect the stuffing box by allowing flush water or pressure to enter. A lantern is a vessel or device that covers up or protects a light source. Protection - The term lantern ring comes from the primary use of the word lantern.Lantern rings simultaneously serve three main purposes: Despite its simplistic appearance, it plays a crucial role in the successful operation of a pump system. A lantern ring is a perforated hollow ring located near the center of the stuffing box of a pump.
