POWERpack graphite packing cords for pumps, pipe fittings and valves. We supply versions made of expanded graphite, graphite and carbon fibers, including reinforced variants for high pressures and temperatures.
These values are approximate and may be influenced by other factors. We will be happy to consult with our expert to make sure you make the right choice.
Cord knitted from pure expanded graphite yarn without binders. Very flexible and pliable.
Sealing cord made of pure expanded graphite yarn reinforced with braided inconel net. Increased pressure resistance.
Yarn made of pure expanded graphite without binders. Corners reinforced with braided yarn of pure carbon fibre. Increased pressure resistance.
Yarn made of pure carbon fibre without binders. Impregnation with graphite dispersion with corrosion inhibitor.
Packing cord made of pure graphite fibre without binders. Impregnated with graphite dispersion with corrosion inhibitor. Good chemical and mechanical resistance.
Used to seal the stuffing boxes of pumps, valves and other industrial equipment. They offer thermal conductivity, a low coefficient of friction and resistance to a wide range of chemical media. They are particularly suitable for applications involving high operating temperatures and pressures. Individual versions differ in the materials used, braid construction and any reinforcement.
For other operating conditions, we also supply Teflon and synthetic packing cords.
Expanded graphite cords are flexible and conform well to the stuffing box. Versions reinforced with carbon fibers or Inconel mesh offer greater resistance to extrusion under high pressure. Graphite and carbon fiber packing cords differ in their properties and applications. When choosing a cord, it is important to consider the medium being sealed, operating temperature, pressure, and type of movement.
Graphite packing cords offer a broad range of chemical resistance, and selected versions can be used with water, steam, oils, acids, alkalis, and solvents. However, they are not generally suitable for strongly oxidizing media. Suitability for a specific application must be assessed based on the properties of the medium and the technical specifications of the cord selected.
