PTFE YARNS

PTFE fibres have a high resistance to chemical attack in both acidic and caustic applications.

Packings braided from PTFE fibres offer outstanding performance in highly corrosive environments as well as under less severe operating conditions. They have a low coefficient of friction and high compressive strength. These packings are available in virgin grades, lubricated and graphite filled versions as well as in expanded form. 

K49

Construction

Using the cross braiding system, K49 is manufactured from a PTFE yarn with non-migratory graphite impregnation. The combination of the PTFE and graphite provides both effective lubrication and thermal conductivity. 

Services

A general purpose packing that can be used on all service applications throughout the plant.

Typical Applications

  • General service
  • Alkalis pumps
  • Acid pumps

Reported Values of Performance*

Temperature Range-240°C - 280°C
Pressure Range 0 - 20 Bar**
Sliding Velocity20 m/s
pH Range0 - 14

K4313 - Aramid, Graphite & PTFE

Construction

Using the KLINGER®-Lock cross braiding system, K4313 is manufactured from a combination of yellow aramid yarn and PTFE graphite yarn. The aramid corners provide exceptional wear resistance while the PTFE/graphite acts as a sealer lubricator.

Services

A good all round slurry packing for more acidic applications.

Typical Applications

  • Underflow pumps
  • Process slurries
  • Acid mine dewatering
  • Reciprocating pumps

Reported Values of Performance*

Temperature Range-10°C - 260°C
Pressure Range0 - 30 Bar
Sliding Velocity20 m/s
pH Range2 - 12

K54S/F/H

Construction

Using the KLINGER®-Lock cross braiding system, K54 is manufactured from virgin PTFE yarn and PTFE lubricant. Additional lubrication is optional depending on the process requirements.

Services

An excellent choice for plant wide use especially when a clean, non-contaminating packing is required with a very high degree of chemical resistance. Can be used in virtually all media including strong acids and alkalis. K54 is supplied as 3 options:

  • 54F - Oxygen service
  • 54S - Food grade
  • 54H - Chemical process

Typical Applications

  • Chemical valves
  • Chemical pumps
  • Pharmaceutical applications
  • Tanker lid seals
  • Food grade pumps
  • Food grade valves

Reported Values of Performance*

Temperature Range-240°C - 200°C
Pressure Range0 - 120 Bar**
Sliding Velocity10 m/s
pH Range0 - 14

*Maximum values – temperature, pH and speed should not be combined in any one application without careful consideration. Common sense balancing factors are always wise.

**Static applications – pressure range may vary depending on sliding velocity and shaft action.
