Chemical Industry Pump Valve Sealing PTFE Graphite Packing

Product Description

Chemical Industry Pump Valve Sealing PTFE Graphite Packing:
The packing is woven of graphite PTFE yarn twisted through a mixture of PTFE dispersion resins and fine graphite powder plus moderate amount of heat-resistant lubricant.
 
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.
