In March 2010, SINOPEC L-HM 68 anti-wear hydraulic oils won the recognition and recommendation from WEPUKO, a German-based company. A series of examinations and inspections at the WEPOKO lab in Germany proved that SINOPEC L-HM anti-wear hydraulic oils satisfy with WEPUKO’s requirements on high-pressure hydraulic system in anti-oxygenic and anti-wear properties，rubber compatibility and requirements for a hydraulic pump test, so that can be applied to the WEPUKO hydraulic system. Before WEPUKO, the SINOPEC anti-wear hydraulic oils have also obtained approval and recommendation from other large international OEMs including DENISON, Cincinnati and Mannesmann Rexroth.

The German-based WEPUKO is a world-leading company engaged in the design and manufacturing of heavy forging machinery, specializing in manufacturing high pressure triplex plunger pumps, radial plunger pump and other world-class forging and pressing equipment.
