ULMAN T4903 - The base material of this packing, aramid staple fibre, is a synthetic fibre with very high strength. The fibre structure, in combination with the high degree of impregnation with PTFE dispersion, makes the packing particularly suitable for use in abrasive environments. Although the packing absorbs abrasive particles, they cannot damage its structure or impair its performance. Another important advantage is its high resistance to cutting and wear.
Applications
• Chemical industry: acids, alkalis, solvents
• Energy and power plants: steam, condensate, hot and cold water
• Food and pharmaceutical industry
• General plant engineering: oils, greases, ammonia, lime milk
Thanks to its high thermal and chemical stability, ULMAN T4903 can be used universally, even under extreme conditions. It provides a high level of operational safety and ensures a long service life, even under changing process conditions.

Our Logistics – Your Service
Innovative, environmentally friendly and efficient
In addition to innovative techniques, our logistics has 2,870 sqm of process surface. We have the world's first AutoStore storage system on two levels. Both grits are connected to each other by means of special lifters. In total, up to 31,000 containers can be stored in a very confined space. Due to this subdivision, up to 240,000 storage areas can be managed most efficiently.
