  1744 - a highly wear resistant Aramid/Kevlar packing; we recommend the use of hardened shafts or protective sleeves (40-60 HRC).

1744UP - a "shaft protecting" universal packing based on flossy aramid staple fibres, sealed with a high percentage of PTFE dispersion and lubricant. 1744UP is also suited as bottom ring ("absorption of solids").

  FMPA approval (FMPA = food stuff contact approval)

MULTISERVICE packing, wear resistant, long service life, "shaft protecting".

Due to good lubrication with certain "dry run characteristics", it is well suitable for agitators/mixers.

Chemical packing, especially for applications for which no graphite particles are allowed (e.g. with oxidizing media).

High pliability - dense structure and good lubricating properties.

Main area of application: chemical and pharmaceutical industries, food industry.

Also a packing for fittings, suitable for air- and gas control valves.

The packing for the higher temperature range with excellent thermal conductivity.

Special areas of application: energy sector, petrochemical industry, hot water, heat transfer oils, hydrocarbons, hot gases etc. (Not suitable: with strong oxidizing materials).

Alternative: Pure graphite fibre packing with graphite powder dispersion for high temperature applications (max. 500 C; 10 bar): Typ1999.

   

   
  Saftey recommendations:
Packings that contain graphites like CHETRA 1777MS, 1777, 1777HS, 1766, 1799, 1799V, 1980, 1988(RS), 1990, 1990V, 1999 etc., cannot be used with strong oxidizing media, such as oleum, fuming nitric acid, gaseous flour and extremely strong solvents with a washing-out effect.
