Packing Seal

Packing seal material should have a certain degree of plasticity. Under the clamping force can produce some of the radial force, and close contacts with the shaft. Have sufficient chemical stability. Not pollute the medium, not medium foam expansion filler, filling in the impregnation medium is not dissolved, fill material itself does not corrode sealing surface. Good self-lubricating properties. Wear, low coefficient of friction. There is little eccentric shaft, the floating filler should be sufficient flexibility. Create a simple, easy loading.
Packing seal used in the process machinery industry machinery and equipment, moving parts such as seals, such as pumps, compressors, vacuum pumps, mixers, reactor shaft seal and pump, reciprocating plunger or piston compressors, and to do spiral movement of valve stem seal between the fixed body。
