Features

Buramex SF 6335 is a Nomex packing (100% white, elastic synthetic fibers) based on aramid with silicone oil-free lubricant. When it is manufactured, the synthetic fibers are compactly and diagonally braided. The packing is preferred for use in the cellulose, paper, food and sugar industries, in breweries, in waste water technology or when treating water in power stations, for cooling water, abrasive river water and in turbine oil circuits.

Advantages

  • Wear-resistant
  • Resistant to abrasive media
  • High cross-sectional stability and structural strength
  • Good sliding properties
  • Treats shafts gently
