      Surface roughness has a very import influence on the life and leakage performance of a reciprocating. The functional realiability and service lifr of a seal depend to a very great extent on the quality and sutface finish of the maring surface to be seales. Scores, scratches, proes, concentric o...Read more »

    Too high pressure values combined with excessive fitting clearance values between rod/head and liner/piston are the main cause of seals deterioration due to extrusion in the medium run. Resulting in fluid leakages. Besides the typical operating pressure generated by the hydraulic system, other pr...Read more »
