1744
- a highly wear resistant Aramid/Kevlar (T.M. Dupont) 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.
