Applications & selection
Typical uses
- Rotary shafts
- Reciprocating pumps
- Static sealing
Industries: Food processing, Pharmaceutical, Chemical.
Selecting the right construction
State shaft and stuffing-box dimensions, medium, pressure, temperature and speed. Review each limit for the actual duty; catalogue maxima are not necessarily simultaneous ratings.
Chemical resistance depends on the polymer, fillers, inserts and process conditions. Confirm the exact medium and concentration; general PTFE properties do not establish a complete assembly's service rating.
