PTFE ROTARY SHAFT SEALS
PTFE ROTARY SHAFT SEALS
- Outstanding chemical resistance and wide temperature range.
- Suitable for high peripheral speeds and good pressure stability.
- Can operate with insufficient lubrication and dry running.
- High wearing resistance of the sealing lip with low friction and breakaway forces.
- High flexibility in lip design.
- Screw compressors, rotary compressors, pumps, blowers, centrifuges, and machine tools.
- Max. peripheral speed: 30 m/s.
- Temperature range: -40 to +220°C.
- Max. pressure: 15 bar.
- Housing: Aisi 304.
- O-Ring: FKM.
- PTFE-lip: F10-293.
Operation limits are based on experience and should be assessed for each application. Radial contact pressure is achieved through a special moulding process, and an O-Ring is used for internal sealing. High-quality materials are used to cover a wide range of applications.
Design Recommendations- For higher speeds and tightness, a hydrodynamic return feed in the PTFE lip or running surface is recommended.
- Recommended shaft roughness: Ra 0.2 – 0.8 µm, Rz 1 – 4 µm.
- Do not stretch the internal diameter of the lip more than 0.5 mm during assembly.
- Inspect the seal, shaft, and assembly tool for damages.
- Factory and Head Office: Castelli Calepio, Italy.
- Sales Offices: Germany, Switzerland, Austria, North America, Asia-Pacific.
- EN 9100: 2018, ISO 9001: 2015, ISO 14001: 2015.

PTFE rotary shaft seals The radial contact pressure is achieved through a special moulding process of the sealing lip. To avoid internal leakage and for a better internal tightness, Fluorten uses an O-Ring as internal seal. In order to cover the widest possible range of applications, only high-quality materials are used. Outstanding chemical resistance Wide temperature range Suitable for high peripheral speeds Good pressure stability Can be used for insufficient lubrication and dry running High wearing resistance of the sealing lip Low friction and breakaway forces High flexibility in the lip...
