Special Sealing Products
Special Sealing Products are customized solutions with special geometries or application requirements. As they are always individually designed and produced, you need a sealing solutions expert with excellent material, product and application know-how. Freudenberg Sealing Technologies is the top innovator in the field, providing you with the maximum technical competence in consulting, engineering and manufacturing.
PTFE Stuffing Box Packing for Pumps and Armatures
Play By Your Own Rules
Special parameters require special seals. So-called stuffing box packings have been tried-and-tested for extremely high temperatures and chemical resistance in pump and valve applications. They offer an excellent sealing effect while maintaining constant elasticity. Stuffing box packings are firmly pressed into the installation space and remain elastic even with steady changes in temperature and pressure. Freudenberg Sealing Technologies packings have been proven to be flexible in other ways as well. For rapid repairs, rings can simply be cut from the roll and mounted. A long service life, high extrusion stability and dry-run capabilities round out the profile of these seals.
The ideal stuffing box packing for every kind of static or dynamic application – that is the goal of Freudenberg Sealing Technologies product developers. To meet this requirement, the company’s standard portfolio already includes a wide variety of different materials and designs.
Special Stuffing Box Packings for the Process Industry
Stuffing box packings are found in many applications in the chemical industry. In these cases, they are especially well suited for use in solvents and concentrated acids and alkaline media, or at very high temperatures. This special product line, including the PTFE-impregnated packing nonwoven Valtec, leaves nothing to be desired, even when it comes to FDA approvals for the food industry.
