HiPerLip® - PTFE Rotary Lip Seal with Metal Casing
PTFE Rotary Lip Seal | Type K2
Teflon rotary lip seal with dual primary lips.
- Suitable for medium to high speed application
- Suitable for low to medium pressure
- Abrasive-Resistant and pressure-stable, for use in fans, pumps, compressors, gear-boxes, and engine crank case.
- Either clockwise (CW) or counter- clockwise (CCW) threaded PTFE lip can be used to pump lubricating oil away from the seal.
- Low friction can be achieved via hydrodynamic effect on the sealing lip.
Application Range
- Speed: ≤ 18 m/s
- Pressure: ≤ 35 bar
- Temperature: -150°C ~ 225°C
