※ PTFE fiber packing in pure PTFE fiber packing but with
Greatly enhanced ability to seal high-speed shafts with the
addition Of inactive and heat-resisting agents. It maintains
the same features as FP-550F; resistance to chemical and mechanical
Attacks. Great dimensional stability. effective seal with
low gland Pressures, etc.
※ As PTFE is low in thermal conductivity and big in thermal
Expansion. frictional heat is not conducted to the outside
of the stuffing box but trapped inside and damages the packing,
thus this packing is not recommended for high speed pumps |
