Description
Product Overview
The SXKJDM Graphite Braided Compression Packing is engineered as a high‑performance rope seal designed for demanding industrial environments. Each packing is fabricated from pure expanded graphite wire that is meticulously braided and reinforced with a blend of glass fibre, copper, stainless steel, and nickel wires. This composite construction delivers a unique combination of flexibility, compressibility, and exceptional mechanical strength, allowing the seal to conform to irregular shaft geometries while maintaining a tight barrier against leakage. The product dimensions of 0.79″ diameter and a 36‑foot length per roll provide ample coverage for a wide range of pump glands, valve stems, and mechanical seal applications. With a temperature tolerance ranging from -58°F (-50°C) up to 1112°F (600°C) and the ability to withstand high pressures, the packing is suitable for sealing hot water, steam, superheated vapour, oils, chemicals, solvents, and a variety of other fluids commonly encountered in power generation, chemical processing, mining, and municipal water treatment facilities. Its self‑lubricating nature reduces friction and wear, extending the service life of both the packing and the equipment it protects. The product is chemically inert, thermally stable, and resistant to deformation, ensuring reliable performance even under continuous operation and extreme thermal cycling.
Usage
Designed for versatility, this graphite braided packing excels in a multitude of real‑world scenarios. In thermal power plants, it is commonly employed on ash removal pumps, slurry pumps, and feed pumps where high‑temperature steam and abrasive particles are present. Chemical plants benefit from its resistance to corrosive solvents, acids, and bases, making it an ideal seal for reactors, distillation columns, and heat exchangers. Mining operations rely on its durability to handle abrasive slurries and high‑pressure water jets used in ore processing. Municipal and wastewater treatment facilities use the packing to seal pumps that handle low‑temperature liquids and aggressive cleaning agents. The flexible nature of the braid allows easy installation on shafts with varying diameters, and the 36‑foot length ensures continuous coverage without the need for splicing, reducing installation time and potential leak points. Its performance in both high‑temperature (up to 1112°F) and low‑temperature (-58°F) environments makes it a universal solution for sealing applications across a broad temperature spectrum.

FAQ
What fluids can this packing seal effectively?
The packing is suitable for sealing hot water, steam, superheated vapour, oils, chemicals, solvents, ammonia solutions, hydrocarbons, and low‑temperature liquids such as boiler feed water. Its chemical inertness and temperature tolerance make it versatile for most industrial fluids.
How does the self‑lubricating property work?
Expanded graphite naturally possesses a low coefficient of friction, allowing the braid to glide smoothly against rotating shafts. This property eliminates the need for additional lubricants, reduces wear on both the packing and the equipment, and helps maintain a consistent seal over long operating periods.
Can the packing be reused after removal?
While the material is designed for long service life, reuse is generally not recommended because the compression set may have altered the braid’s geometry, potentially compromising sealing performance. For critical applications, it is best to install a new roll to ensure optimal reliability.
What installation guidelines should be followed?
Ensure the shaft surface is clean and free of debris before installation. Measure the shaft diameter accurately and select the appropriate packing size (0.79″ diameter in this case). Apply the packing evenly around the shaft, avoiding overlaps, and compress it to the recommended set‑down pressure as specified in the equipment manual. Verify that the packing length covers the sealing area completely.
Is this product compatible with stainless steel pump housings?
Yes, the graphite braid’s inert nature and the inclusion of stainless steel reinforcement make it fully compatible with stainless steel housings, preventing galvanic corrosion and ensuring a stable seal over time.
