Chem-2 Pump & Valve Packing

Chem-2 Packing

General service compression packing, rotary and valve applications 0–14 pH.

Features / Benefits

  • Low coefficient of friction, self lubricating – increases equipment life & reliability MTBR (meantime between repairs).
  • High strength fiber – reduces sleeve wear & maintenance costs.
  • Universal packing applications – saves inventory costs.
  • Easy to cut, install and remove.

Typical Applications

  • Extreme chemical service.
  • Acids, caustics and petroleum products.
  • Higher shaft speeds than conventional Teflon™ packing.
  • Soft conformable packing for broad range of pump and valve applications at medium pressures.
  • Rotating equipment pumps, agitators, mixers, blenders, reciprocating pumps & valves.
  • Universal packing applications.
