Where is the lantern ring located on a pump?

The lantern ring is an important component in pump design, specifically related to sealing and lubrication. Located at the sealing water connection, the lantern ring serves as a conduit for sealing water to enter the stuffing box of the pump. This sealing water is crucial for cooling and lubricating the packing or other sealing arrangements that prevent leakage of the pump's fluid.

By positioning the lantern ring at the sealing water connection, it ensures that the flow of sealing water effectively reaches the packing material that surrounds the pump shaft. This contributes to preventing wear on both the packing and the shaft while enhancing the efficiency of the sealing arrangement. The use of sealing water through the lantern ring helps to maintain proper operating conditions within the pump, ultimately prolonging its lifespan and improving reliability during operation.
