Definition -A Lantern Ring is a ring-shaped component installed between packing rings in a stuffing box of a pump or valve. Its purpose is to distribute sealing or flushing fluid evenly around the shaft to cool, lubricate, and prevent leakage or ingress of contaminants. Lantern rings are commonly used in centrifugal pumps, compressors, and valves in industrial fluid-handling systems.

Sunmach manufactures precision-engineered Lantern Rings using superior-quality Nickel Alloys and Stainless Steel materials. Each ring is custom-built to meet customer design requirements and exact dimensional tolerances. These components are engineered for high-reliability performance in critical industrial systems.
