HLP230 HLP231 Cotton yarn packing Cotton yarn packing impregnated with lubricant and graphite

Pre-impregnated, twisted cotton thread is completely impregnated during weaving, which is an economical packing. This colorless impregnant prevents any fading and contamination of the product. Therefore, the packing is mainly used for cleaning media. Due to the seawater resistance of the impregnant, the packing can also be used to seal the stern tube and the propeller column. It can be used in water, sewage, sea water, and salt solutions. <br> 231 cotton yarn packing impregnated with graphite grease. It is water resistant, and the applied parameters are the same as 230.

HLP240 HLP241 Acrylic Packing Acrylic fiber and silicone core packing

It is made of polypropylene wax fiber as raw material, reinforced, woven, and impregnated with polytetrafluoroethylene. With high strength, abrasion resistance, erosion resistance and other properties, it is an ideal substitute for asbestos packing. It is suitable for pumps, valves and kettles with higher linear velocity and higher pressure as packing seals. <br> 241’s materials, processes, and application fields are equivalent to 240. It is supplemented with silicone rubber in the center part, and the compression compensation performance of the product is better.

HLP220 Asbestos PTFE packing

This packing is woven with white asbestos fiber bundles, impregnated with polytetrafluoroethylene emulsion (lubricant can be added on request). This is a softer packing, which is often used to seal various chemical pumps. If used in reciprocating pumps and higher linear speeds (within 10m/s), it is recommended to use asbestos PTFE packing with lubricant penetration.

HLP260 Carbonized fiber packing

This kind of packing is made by first carbonizing polyacrylonitrile fibers into carbonized fibers, and then dipping the polytetrafluoroethylene emulsion containing graphite particles to weave into packing. This kind of packing can be used in strong acid or weak base media and dynamic sealing parts with a small amount of solid particles.

HLP270 Carbon fiber packing

Carbon fiber graphite packing is made of high-strength, high-modulus continuous carbon fiber filaments, which are softened and then woven. This packing is infiltrated with a mixture of graphite micropowder and polytetrafluoroethylene emulsion, and a lubricant is added. It not only has excellent chemical stability and thermal conductivity, but also has high strength. It is especially suitable for the sealing of various rotary pumps and reciprocating pumps that are chemically corrosive and contain granular media.

HLP280 PTFE packing

PTFE packing is a kind of braided packing made of PTFE thread. Do not impregnate any PTFE emulsion and grease. It is recommended to be used in IC-related production lines, fine chemicals, food, pharmaceuticals and other operations where contamination is not allowed. It can be used to seal all chemical media except molten alkali metals.

HLP285 PTFE fiber packing

Die Packung besteht aus reiner Polytetrafluorethylen-Faser, die zu einem quadratischen Querschnitt verwoben und dann mit Polytetrafluorethylen-Emulsion imprägniert wird. Hat eine hohe Querschnittsdichte und strukturelle Festigkeit. Es ist beständig gegen fast alle chemischen Medien und weist eine hohe Beständigkeit gegen mechanische Beschädigungen auf. Der niedrige Reibungskoeffizient macht die rotierende Welle flexibel und verbraucht weniger Energie. Durch die Stabilität von PTFE und kein unter Betriebsdruck extrudiertes Schmiermittel hat es eine lange Lebensdauer.

HLP290 Graphit-PTFE-Packung

Graphite-containing polytetrafluoroethylene packing is braided with polytetrafluoroethylene thread containing graphite particles. It is recommended for pump seals for almost all chemical media. <br> The low friction coefficient makes the packing have stability and long life. It also has strong tear strength and high thermal conductivity. The self-lubricity of the packing will not scratch the shaft and can reduce the replacement cost of the shaft sleeve.
