We offer replacement friction pairs for the KSB KWP (KWPK) 4K single mechanical seal. The KSB 4K mechanical seal is bidirectional, balanced, with large springs located outside the pumped fluid.
Usually, the friction pairs are the most worn elements in this seal, as the mechanical seal works with abrasive liquids.
Materials used to make friction pairs:
Fixed ring SiC(Q1)/U (tungsten carbide) as an alternative.
Moving ring SiC (Q1) / U (tungsten carbide) as a special variant.
Elastomers EPDM (E) / FKM (V) / FFKM (K) / FEP coating (M1).
