Specification of
Merkel Arochem S 6216
Pump packing suitable for high shaft speeds and
abrasive media
Product description
Merkel Arochem S combines the advantages of
two advanced yarn materials 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
packing extrusion and protects against abrasive
media. Merkel Arochem S contains a universally
stable silicone-free lubricant. This ensures superior
lubrication during the run-in phase.
