What is the primary purpose of a lantern ring in water treatment systems?

The primary purpose of a lantern ring in water treatment systems is to cool and lubricate packing. This component is typically used in pumps and valves where packing is utilized to create a seal. The lantern ring serves as a passageway for lubricants or cooling fluids, allowing for effective heat dissipation and reducing friction between the packing material and the moving parts.

When packing material becomes too hot or dry, it can wear out quickly, leading to leaks and increased maintenance costs. Thus, the inclusion of a lantern ring helps ensure the longevity and reliability of the sealing element, ultimately contributing to the efficient operation of the system. It acts as a conduit that permits continuous lubrication and thermal regulation, which is essential for maintaining optimal performance in water treatment processes.
