Stuffing box packings from Freudenberg Sealing Technologies: Versatile use in the process industry

Stuffing box packings offer an excellent sealing effect with constant elasticity. They are firmly pressed into the installation space and remain elastic even with constant changes in temperature and pressure. This is why the stuffing box packings from Freudenberg Sealing Technologies are used in a wide range of applications:

Stuffing box packing for the process and chemical industry

In the process industry, they have proven themselves for the highest temperatures and chemical resistance in applications for pumps and valves. They also offer high extrusion resistance and dry-running capability. For quick repairs, rings can simply be cut from the roll and fitted.

We also offer special stuffing box packings for the chemical industry with its demanding applications. For use in concentrated acids and alkalis, solvents or at very high temperatures, special programs such as the PTFE-impregnated Valtec packing fleece, which also has FDA approval for the food industry, are suitable.

Stuffing box seals made of different materials for different requirements

Our range offers the ideal stuffing box packing for every type of static and dynamic application. That's why even the standard portfolio includes a variety of materials and designs - to meet every industry requirement.

Merkel Arochem S 6216, for example, consists of two highly developed yarn materials. The wear-resistant aramid yarns prevent extrusion and protect against abrasive media such as organic solvents, hydrocarbons or medium-concentrated acids.

These stuffing box packings can be used to perfectly seal high-speed shafts. They also have excellent sliding properties, low friction and are extremely wear-resistant, making them perfect for high pressures in centrifugal or plunger pumps.

Stuffing box packings from FST offer a long service life

Stuffing box packings are used to reliably seal pumps and fittings. The packing consists of a close-meshed framework of machine-interlaced yarns made of different materials and an impregnation. The impregnation makes it possible to close the cavities in the packing braid, increase media resistance, optimize running properties and improve heat dissipation. Leakage paths through the packing are thus avoided.

We focus on the highest quality and a long service life for all our stuffing box packings.
