  • Seals
    Liebherr uses a compact arrangement of seals and an innovative sealing system in the series to satisfy the most exacting of standards. A tandem sealing system consisting of a primary and a secondary seal is used for the rod seal. This relieves intermediate pressure and reduces the stick-slip effect.
