• With a precise square section of 0.47in×0.47in (12×12mm), it fits accurately into compatible equipment, guaranteeing optimal sealing efficiency.
• Each case contains 75 meters (246.06ft) of packing, offering a substantial quantity suitable for large-scale equipment or multiple sealing tasks in demanding industries.
• The net weight of 20kg (44.09lb) per case indicates the durability and density of the pure cotton material, ensuring long-lasting sealing performance.
• Its yellow color allows for easy visual inspection, enabling quick identification of wear or damage in sealing applications.
• It is widely used in thermal power plants, chemical, metallurgical, steel, and coal mining industries, and is suitable for shaft seals in water-lifting machinery, centrifugal pumps, compressors, vacuum pumps, mixers, ship propellers, piston pumps, reciprocating compressors, refrigerators, and various valve stem rotary seals.

Usage Instructions

1. Ensure the equipment (pumps, valves, rotating shafts) is shut down and isolated from all power sources before beginning the installation process.
2. Remove the old packing (if present) and thoroughly clean the packing chamber to remove any debris, residue, or old sealing material.
3. Cut the XHD pure cotton packing to the required length, ensuring clean, square cuts for optimal sealing. Use appropriate tools suitable for cutting cotton material.
4. Install the packing into the packing chamber, layer by layer, ensuring each layer is properly seated and aligned. For square section packing, ensure the corners fit snugly into the chamber.
5. Adjust the packing gland to achieve the desired sealing tightness. Pure cotton packing requires careful adjustment to balance sealing efficiency and friction levels, avoiding over-tightening which could cause excessive wear.
6. After installation, conduct a leak test under operating conditions. Monitor the seal for any signs of leakage or abnormal operation. Adjust the gland as necessary during initial operation, especially in applications like water-lifting machinery or centrifugal pumps.
