Asbestos PTFE packing is made of white asbestos fiber cords impregnated with PTFE dispersion. Soft in texture, this material is suitable for sealing pumps for various chemicals. However, packing impregnated with lubricants is recommended for use with reciprocating pumps or for sealing in places where high linear velocity.
Application conditions:
1) Max. working temperature: -75 ~ 260o
2) Max. working pressure: 2Mpa （rotary pump）
Max. working pressure: 10Mpa （reciprocating pump）
Max. working pressure: 15Mpa （valve）
3) pH value: 2-12
4) Linear speed: 0 - 10m/s（rotary pump）
Linear speed: 0 – 2m/s（reciprocating pump）
Linear speed: 0 – 2m/s（valve）
5) Cross Section: ≥1/8” ~ ≤3”(3X3—75X75mpa)
6) Density: 1.35 ~ 1.45g/cc
