Lantern ring for Demag machinery

The lantern ring, identified by part number 01461377, is a component used in packing seal systems, typically found in pumps and valves within heavy machinery. Its primary function is to create an annular space inside the stuffing box, allowing for the injection of sealing, lubricating, or cooling fluids. This process helps dissipate heat generated by friction, lubricates the packing, and prevents the ingress of contaminants or the leakage of the primary process fluid.

This component is designed for use in Demag equipment. It is typically installed in systems where sealing integrity is required for the operation of hydraulic or water pumps. The design features radial holes that allow for the uniform distribution of the injected fluid around the shaft or stem. Maintaining the correct dimensions is necessary to ensure a proper fit within the stuffing box and to facilitate the effective distribution of the fluid.

In a sealing system, the lantern ring acts as a spacer that ensures the packing remains properly lubricated and cooled. When the fluid flow is maintained through the ring, it prevents the packing from overheating or hardening, which in turn protects the shaft from premature wear and reduces the risk of seal failure.
