Stuff Box packings for Pumps
UNIVAL consists of graphite-filled lubricated PTFE yarn. The special braiding structure
offers the benefits of low thermal expansion and excellent heat conduction. Due to its low friction characteristics UNIVAL can also withstand dry running up to
a certain limit
A DIAPLEX® braided rotary pump packing made from fine cotton yarn, impregnated with a
universally resistant mineral lubricant.
AROLAN II is made from highly wear-resistant aramid yarn with a special PTFE
impregnation and a universally stable running-in lubricant.Its high level of resistance to abrasion as well as to temperature
UNICHEM is made from pure PTFE yarn with an additional PTFE impregnation and lubricant.
It has a very dense but soft and pliable structure so that sealing can be achieved with a minimum of gland pressure. Due to its excellent
lubrication UNICHEM exhibits very low friction.
Unichem ST 6388
AROCHEM combination braid consists of aramid yarn and PTFE compound yarn. The packing is
particularly stable due to DIAPLEX® braiding.
Hot and cold water, steam, organic solvents, chemical raw materials, oils, fats, diluted
acids and alkalies.
AROCHEM S combines the advantages of two advanced yarn materials in the sealing of
high-speed shafts. The particular running qualities of thermally stable PTFE-graphite compound yarn ensure shaft protection and even short-term "dry-running"
AROFLEX is a greaseimpregnated pump packing. Smooth running and stability at high
temperatures ensure high performance and a long service life.
Media Kalt- und Heißwasser, Salzlösungen, organische Lösungsmittel,Kohlenwasserstoffe, Öle,
Fette, verdünnte Säuren und Laugen, Dampf bis 180°C
Cold and hot water, steam, aqueous solutions, almost universally against acids, and
lyes.Exceptions: strongly oxidizing salt solutions, concentrated sulphuric and nitric acid.
UNISTAT is manufactured from graphite-filled PTFE yarn. The high level of graphite
ensures excellent heat conduction while the PTFE content provides low friction performance.
Hot water, steam, gases, oils, acids and alkalis. Exception: strongly oxidising acids
like sulphuric acid and nitric acid in high concentrations.
Hot and cold water, salt solutions, organic solvents, hydrocarbons, oils, greases, diluted
acids and alkalies, steam up to 180°C.
GRAFOLAN is made from graphite yarn, which is obtained from carbon fibres subjected to
an intensive thermal conversion process. This packing has excellent chemical stability and high temperature resistance.
KOMBILON 6742 is an elastic combination braid made from carbon and PTFE yarns. It
is impregnated with a special PTFE compound and running-in lubricant.
The packing has very good running characteristics and protects the shaft from neutral and
abrasive media such as mud and crystalline suspensions.
This special carbon yarn packing is superior to all greased asbestos and natural fibre
packings because of the special shaft protection qualities.
VARILON SG is especially suitable for sealing high-speed shafts. Due to the high
amount of graphite-filled PTFE yarn, the packing has very good running qualities and high heat conduction. The aramid yarn provides a high strength.
Uniflex is manufactured from a carbonised yarn with a special PTFE-graphite impregnation.
The packing is very flexible and extrusion-resistant.
Cold and hot water, solutions containing solid particles, oils, greases, solvents,
foodstuffs. UNIMIX is a newly developed injectable compound, manufactured from PTFE fibres and solids with a high duty lubricant.
Unival II 6326
Used with end rings of Arolan 6215, Flexalon 6250 or Unichem 6313 UNIMIX is ideal
for sealing against abrasive media as well as on damaged shaft surfaces.
UNIVERDIT has extremely good resistance to gas permeation and has the ability to embed
abrasive particles. UNIVERDIT remains self-lubricating even during extended periods of operation and therefore reduces friction on shafts and
Lyes, solvents, bitumen, almost all acids. (Exceptions: oleum, highly concentrated nitric
