Our challenge is to design mechanical seals that can withstand a variety of media, different aggregate states, and different pressures and temperatures, and to provide special solutions for small-scale installations with a contact area of several meters. Each application has its own special requirements, our job is to provide the best sealing solution. Its materials as Seal face: Carbon graphite resin impregnated (B); Seat G9: Silicon carbide (Q1, Q2); Special cast CrMo steel (S), Aluminium oxide (V). The advantages of mechanical seal 2102 such as Economical seal solution, No damage of the shaft by set screws, Short installation length possible (G16). Meanwhile, it also is featured as: for plain shafts, Single seal, Unbalanced, Conical spring rotating and Dependent on direction of rotation.
