Features

Supraflon 6435 is a packing made from aramid staple fibers with silicone oil-free universal lubricant and PTFE impregnating agent. The aramid fibers are diagonally braided. It is used, in particular, in the paper and chemical industries, and in power stations.

Advantages

  • High resistance to abrasive media
  • Extraordinary cross-sectional tightness
  • Good sliding properties
  • Highly wear-resistant
  • Treats shafts gently

Operating range

Pumps
Pressure: p = 20 bar
Sliding velocity: vg = 20 m/s
Plunger Pumps
Pressure: p = 100 bar
Sliding velocity: vg = 1,5 m/s
Mixers, agitators, kneaders, filters
Pressure: p = 20 bar
Sliding velocity: vg = 2 m/s

Temperature
  • Continuous operation:
    t = -100 °C … +250 °C
  • Steam: tmax = +180 °C

Chemical resistance:
pH = 1 ... 13
Recommended for abrasive media, e.g. lime, sand, solids and sticky media, bitumen and adhesive.

Notes

Because the aramid fibers are highly stable, we recommend a surface hardness of 40 … 60 HRc to avoid wear on the running surfaces of shafts and sleeves.
