Seals are our business and we are really good at it
The experience gained over generations enabling STASSKOL to develop new products and materials which have created a strong demand for the products.

All of the sealing elements are designed specifically for the application. This is what makes STASSKOL different from other companies.

Plastic as an appealing bearing material at higher temperatures Metals are replaced by polymers more and more often. STASSKOL developed the ESKAFLON 449 as a particularly attractive bearing material at higher temperatures.
Plastic as an appealing bearing material at higher temperatures
Metals are replaced by polymers more and more often. STASSKOL developed the ESKAFLON 449 as a particularly attractive bearing material at higher temperatures. If you replace metals with polymerss, in addition to the high chemical resistance, the low density of the plastics is a great advantage, because this saves weight. However, the rigidity of the materials must stand up to the challenges of the application. In order to increase the strength, we have introduced hard coal, carbon fibers, but also fabric mats consisting of carbon fibers into the high-performance polymers. With particularly high filling levels, we achieve mechanical properties that come very close to those of metallic materials. In order to be able to achieve filling levels of over 50 vol.-%, STASSKOL has further developed hot compression molding as a processing method. An advantageous side-effect of the strongly increased rigidity of the polymers is the reduction of their thermal expansion. PTFE even has a very high thermal expansion coefficient compared to other polymers. With our ESKAFLON 449, we have succeeded in reducing the thermal expansion coefficient

No more spillage at horizontal mixer for animal feed The STASSKOL DynamicSeal Faceseal combines the advantages of the known shaft seals without compromising on functionality.
No more spillage at horizontal mixer for animal feed
The STASSKOL DynamicSeal Faceseal combines the advantages of the known shaft seals without compromising on functionality. The axially contacting sealing surface minimizes leakage on the one hand through direct contact and on the other hand through the redirection of the material flow from the axial to the radial direction. Efficiency increase after installation The new SDF has already proven its excellent performance in a twin-shaft horizontal mixer for animal feed. In the batch process, several barrels of cereal flour were mixed with various abrasive fillers such as stones and minerals per mixing process. With a shaft diameter of 200 mm and a speed of 50 min-1, a noncircular run of 0.7 mm was found. With the conventional seal originally used, a product leakage of 25 kg per day was recorded. After replacing it with the new SDF, which occupies exactly the same space as the previous seal, the leakage was zero. At the same time, the consumption of sealing air was minimized, thus increasing the energy efficiency of the plant.
