Construction
- High purity, high strength graphite filament yarn treated with fine graphite powder to seal individual fibers. Surface coated with molybdenum disulfide.
HS-4000M Packing
Features and Benefits of HS-4000M
- High speed capability.
- Low friction – runs cooler, lasts longer – reduce flush water (greatly reduce product dilution).
- Broad chemical compatibility 0-14pH.
- Non-Abrasive – Sleeves last longer.
- Reduce maintenance and parts costs.
- Maximize equipment reliability and performance.
- Dissipates heat better than conventional compression packing materials. Increase MTBR – mean time between repair – less sleeve damage.
- Dimensionally stable fiber (less volume loss).
