Gland packing prevents leakage around the pump shaft by using compressed rings of flexible material. It is ideal for applications where mechanical seals are impractical, especially in older or abrasive services. Lantern rings are inserted between packing rings to allow flushing fluid to cool and lubricate the shaft. This flushing also prevents contaminants from entering the pump cavity, extending equipment life. Both components are commonly used in oilfield pumps handling crude oil, slurries, or chemical-laden fluids. Mobyflo supplies high-quality, oil-resistant packing materials and precision-fit lantern rings designed for the most demanding industrial environments.
