Carsten Holms CH AR11 combines the physical strength of Kevlar® with the sealing properties of TEFLON® fibres. The packing is further lubricated yarn by yarn with PTFE dispersion and inert lubricants.
CH AR11, Kevlar® and PTFE fibre packing, is square inter-braided to maximise the benefits of these two remarkable fibres. Kevlar® fibres are specially braided from the core to the corner-posts for dimensional stability and to take maximum advantage, within the packing construction, of the yarns steel-like strength. The TEFLON® yarns are braided to the packing surfaces to enhance sealing capability.


PROFILE

PRODUCT ADVANTAGES
• Easy installation and removal
• Resistant against general chemicals
• Withstands high pressure
• Ideal for piston sealing
• Enhanced sealing capability

APPLICATION
CH AR11 combines low-friction, complete pH range chemical resistance with high mechanical and dimensional strength. A wide ranging packing, for specification especially in high pressure conditions in chemical or abrasive applications, where alternative single fibre packings may extrude or cause significant shaft wear.
The construction and materials of CH AR11 makes this packing ideal for piston sealing on reciprocating, chemical, slurry and high pressure pumps.

Never use the product when maximum temperature and pressure are combined.
