Carbon packing type EWW/I

High-parameter packing braided of highest-quality pure carbon yarn with very high thermal and mechanical resistance. Additionally, sealing is enriched with impregnant on the basis of graphite and corrosion inhibitor. The packing is characterized by excellent flexibility and low friction coefficient. An additional advantage is full chemical resistance in the range of pH 0 – 14.

Application

EWW/I packing is used mostly in piston and rotor pumps at a very high temperatures and pressures, in contact with hot steam, oils and alkali except for strongly concentrated ones.
