PTFE packing

product model:P2800

PTFE fiber packing is made of PTFE fiber as the skeleton material, and is fully impregnated with PTFE emulsion after weaving. This filling material has good chemical stability to strong corrosive media such as acid, alkali and solvent, wide operating temperature range and low friction coefficient. It has good application effect on urea methylamine pump and concentrated nitric acid plunger pump, especially the service life of asbestos impregnated PTFE packing on methylamine pump with a small amount of crystals.2times.

II.pressure: 3Mpa (rotary pump)

10Mpa (reciprocating pump)

20Mpa (valve)

three. PHvalue: 0-14

IV.linear velocity: 10M/S (rotary pump)

2M/S (reciprocating pump)

five.available section size: ≥1/8"~≤3"(3X3-75X75mm)

VI.density:1.75 ~ 1.85g/cm& sup3;

Note: (1) high temperature lubricant can be infiltrated into the packing as required, density:1.90-2.05g/cm& sup3;

(2) According to the need to add iron red silicone rubber strip elastomer in the core part of the packing.
