Flexpack Ptfe Tanklid Packing

Description: It is made of expanded PTFE yarns with reinforced corner from continuous aramid filament, a combination of proved top qualities. It has high cross-sectional density and structural strength. This structure enhances the lubricability of aramid fiber and reinforces the strength of the pure PTFE packing. This special combination packing takes a very important role for high pressure piston pump application. It is recommended for piston pump in the universally applicable within the PH range 2-13. It is suitable to be used in Chemical, petrochemical, pharmaceutical, food and sugar industries, pulp and paper mills, etc.

PTFE packing It is a interlock braided packing manufactured from pure ptfe yarns pretreated with ptfe dispersion, plus a break-in lubricant to reduce the coefficient of friction. This is a dimensionally stable packing, yet relatively soft and pliable, which has excellent lubricating and running characteristics. It handles all acids, alkalis, and most chemicals, with the exception of molten alkali metals. It is suited for high speed rotary shaft service and is also commonly used on reciprocating pumps, mixers, agitators, and reactors. 2kg or 5kg per spool

Ptfe packing - pure ptfe packing Material: 100% ptfe yarn, without theptfe packing use of additional lubricants or break-in oils. Fast and simple to install, with minimum maintenance requirements. Application areas: Style aidmer76-029 ptfe packing can be used in centrifugal and rotary shafts, reciprocating applications, and valve stems, sliders, mixers, vessels and pumps, power industry etc Application media: Style aidmer76-029ptfe packing is suitable for pharmaceutical and food applications, potable water, solvents, oils, gases, effluents, oxygen etc. 5kgs packed in paper reel, one reel packed in inner box , four boxes packed in outer carton

PTFE Packing With Chemical Resistance And Low Friction CoefficienT PTFE packing or Teflon packing is a braided packing made of high purity PTFE (poly tetrafluoroethylene) yarn without soaking any PTFE dispersion and lubrication. PTFE packing is a kind of self-lubricating, chemical inert, non-toxic and non-hazardous material. In addition, PTFE is called "king of plastic" and causes no pollution to the medium or liquid. More importantly, PTFE is known for its outstanding resistance to chemical attack, low friction coefficient, low water absorption and wide temperature tolerance (including cryogenic applications). Due to the above advantages, PTFE packing is widely used in chemical processing, food processing and pharmacy.

Good flexibility and compressibility. Tough interlock braid. Superior chemical resistance. Resistant to the impact of water, steam, oil, fuel, solvent, acid and alkali. Low friction. APPLICATIONS PTFE packing is ideal for general valve and pump (including rotating, centrifugal and reciprocating pump) applications in chemical processing, food processing, cryogenic applications, industrial gas processing and hospital. White PTFE packing is applied in the valve. PTFE packing for valve

Ptfe graphite packing Interlock braid, using ptfe/graphite yarn and a high temperature break-in lubricant yarn is formed from expanded ptfe in which fine particles of pure graphite have been encapsulated. The resulting packing combines the chemical resistance of ptfe with the heat dissipation characteristics of graphite, thus allowing much higher shaft speeds than conventional ptfe packings. It is chemically inert over the entire 0-14 ph range with these exceptions: molten alkali metals, flourides, aleum, fuming nitric acid, aqua regia, and other strong oxidizing agents. Gh-120 is an excellent general service and corrosive service packing. It is commonly used in pumps, valves, rotating and reciprocating shafts, mixers and agitators, and is especially designed for services involving surface speeds and temperatures higher than those that can be handled by pure ptfe packing. 2kg or 5kg per spool

The packing is made of white asbestos fiber cords impregnated with ptfe dispersion.(addtition of lubricant is operational.) it is soft in texture and suitable as the sealing of pumps for liquidated chemicals. However, packing impregnated with lubricants is reco-mended for use with reciprocating pumps or for the sealing in places where linear velocity is up to 10m/s.

WFY-6100 A is a packing with A grade of quality, the yarn with good tensile strength, and excellent thermal conductivity. WFY-6100 B is economical gPTFE packing, braided from normal graphite PTFE yarn. Application: For use in pumps, valves, reciprocating and rotating shafts, mixers and agitators. Especially designed for services involving surface speeds and temperature higher than those normally specified for pure PTFE packings. Can be safely used in all chemical pump applications with the exception of molten alkali metals, fluoride, fuming nitric acid and other strong oxidizing agents. It is also against water, steam, petroleum derivatives, vegetable oil and solvents.

The packing is a pure PTFE fiber yarn packing braided into wquare cross section and impregnated with PTFE dispersion.High cross-sectional density and structural strength. Inert to almost all chemicals and has great resistance to mechanical attack Low coeffient of friction results in easy shaft running Long lubricant squeezed out under operating pressure.
