Premium Braided Mechanical Packing

Style 50/52

Patented Technology
SWEET SPOT & BEST USES:
Acid Slurries, Downwell pumping and other mining applications.

50% PTFE impregnated Polyimide fiber / 50% “C” filament fiberglass

Construction
A combination of 50% PTFE impregnated, high strength synthetic Polyimide yarn and 50% “C” filament fiberglass. These are twisted together to form individual strands, creating a continuous interaction between the two fibrous elements. The strands are then cross-lock braided. The finished braid is fully penetrated with PTFE.
Characteristics
  • The intimate “all-points” combination of the yarns permits the fiberglass to conduct heat away from the shaft and the synthetic fiber throughout the packing mass, thereby aiding dimensional stability and constant sealing effectiveness.
  • The “C” filament fiberglass and substantial PTFE permeation increase chemical resistance.
  • The superior density reduces migration of particles under pressure.
Applications
Excellent as a superior general service pump packing. Ideal for all applications where non-staining is important. Very “easy” on shafts.
