Advanced Braided Construction: Interwoven from high-purity expanded graphite yarns reinforced with premium synthetic fibers (such as aramid or carbon fiber) to ensure high mechanical strength and structural integrity.
Superior Self-Lubrication: The inherent lubricating properties of graphite significantly reduce the friction coefficient, minimizing heat generation during high-speed shaft rotation.
High Carbon Content: Typically features a carbon content of 98% or higher, providing exceptional thermal conductivity and chemical resistance across a broad range of media.
Corrosion Inhibitors: Treated with specialized sacrificial corrosion inhibitors to protect the pump shaft and stuffing box from galvanic corrosion during long-term operation.
Shaft-Friendly Performance: The soft, flexible nature of the graphite fiber ensures minimal wear on shafts and sleeves, significantly extending the life of expensive pump components.
Excellent Heat Dissipation: Rapidly conducts heat away from the sealing face, preventing "burning" of the packing and maintaining a stable seal even in high-temperature water applications.
Wide pH Range Stability: Chemically inert and resistant to almost all industrial fluids, including water, steam, oils, and mild acids or alkalis (pH range 0-14, except for strong oxidizers).
Low Leakage Rate: The dense, cross-braided structure provides superior volumetric stability and sealability under fluctuating pressures.
