The phenolic fiber packing is braided by high-performance phenolic fiber impregnated with special lubricant, and high-quality PTFE emulsion is soaked again in the braiding process to improve its lubrication quality.
The phenolic fiber packing is braided by high-performance phenolic fiber impregnated with special lubricant, and high-quality PTFE emulsion is soaked again in the braiding process to improve its lubrication quality.
This packing is a universal packing for high-performance and multi-purpose pumps and valves. It can be used for sealing pumps and valves in paper mills, pulp pumps, hydraulic beaters and refiners, as well as wastewater and sewage treatment plants, water pumps, ships, dewatering pumps, power plants, mixers, etc., and is suitable for water, steam, salt water, acid, dilute lye, general chemicals, solvents, petroleum products and other mediums.
The packing has the characteristics of thermal stability and low thermal expansion, and it can still maintain dimensional stability under the condition of alternating temperature and pressure, which is soft and wear-resistant, does not damage the shaft or spindle, and has no pollution to the mediums.
