PGP 3100, PGP 3300, PGP 3400

Expanded graphite braided packing is made from expanded pure graphite yarn, braided into packing through all kinds of technology of braiding. It can be divided into expanded graphite braided packing with inconel or steel wire inserted, expanded graphite braided packing with fiberglass, expanded graphite braided packing impregnated with cotton fiber. The product are almost suitable to all media, such as hot water, steam, acids, alkalis, organic solvents, hydrocarbons, low temperature liquids, etc. The sealing capability is more better and safety. It is the most effective composite parts for solving problems.

PGP 3200   Braided PTFE Graphite Packing.

PGP 3200
This kind of product is made by combining PTFE with graphite. Because in this kind of composite material, both PTFE and graphite have good self-lubrication property, so the products have very low friction factor and good self-lubrication property too. Thus, axles of machinery will not be scratched and the cost for changing axle sleeves will be decreased to a great extent. Owing to good heat conductivity of graphite, working temperature of packing can be increased, hence the working life will be longer. Furthermore, they almost suit to all of chemical media.
??These packing are widely applied to sealing at operating places where contamination is not permitted, for example, for sealing of pumps, valves, flanges in equipment of foodstuff, pharmaceutical, wine-making, petroleum, chemical, power, paper making, printing and dyeing industries.

PGP 4100      Carbon fiber braided packing with PTFE dispersion.

PGP 4100

This packing made of high-quality carbon fiber, impregnated with PTFE dispersion. Because carbon fiber has quite high strength and good heat conductivity and PTFE makes the packing have very good self-lubrication property, thus the product possesses properties of fine anti-chemical corrosion, self-lubrication and heat conductivity, then it will not damage pump shafts and has long working life. It's suitable for almost all corrosive media, organic solvents and mainly used for centrifugal pumps, plunger pumps, mixers and valves.

PGP 5100 Kevlar fiber braided packing dipped with PTFE dispersion.

PGP 5100
T
his kind of packing is made from braiding of aromatic polyamide yarn (Kevlar), which is first dipped with PTFE emulsion then treated with lubricant and inhibitor of corrosion, finally braided to form square cross-section. Because Kevlar yarn has excellent properties with very high strength and module (It is called artificial steel wire.). So compared with other kinds of braided packing, it can resist more severe media and higher pressure. It can be installed separately from other kinds of packing as well as combined with others to from packing sets of different characteristics to be used as end rings.
This kind of packing is mainly used as substitute of asbestos in pump system. Not only is protects environment but also its property is better than asbestos. Even if under very bad conditions where ordinary asbestos packing can't provide satisfied service effect, this kind of packing can do. In addition, its working life is very long, sealing effect more better and it is often used at bad conditions, such as: water pumps at mortar site, tin mine, pulp factory and power plant.
