Pure Graphite PTFE Packing

Model: WT-P201

Graphite PTFE Packing is braided from low-sulphur expanded graphite yarns, which are reinforced by cotton , carbon fiber, glass fiber etc. It has a very low friction, does not damage shafts or stems. It shows good thermal and chemical resistance and high elasticity. To improve mechanical strength, Graphite packing can be reinforced with inconel wire, ss wire, nickle wire etc metal materials.

Introduction

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.
