1. Features
AROCHEM S brings together all the advantages of the AROCHEM combination braids in the sealing of high-speed shafts. The particular running qualities of thermally stable PTFE-graphite compound yarn ensure shaft protection and even short-term "dry-running" without damage. Due to their stability, wear-resistant aramid yarn edges prevent the packing extruding into the sealing gap. AROCHEM S contains a universally stable silicone-free running-in lubricant. This ensures superior lubrication during that running-in phase, which is particularly important in the service life of a rotary pump packing
- robust and durable
- extrusion resistant
- extremely resistant to wear even where solid particles are present
- smooth running
