SINOPEC Ashless anti-Wear hydraulic oil is blended with highly refined base oil with high viscosity index and ashless additive formulation by internationally advanced process. Compared to L-HM anti-wear hydraulic oil, it is especially suitable for the lubrication of hydraulic system with copper/ silver parts. The product comprises several grades such as 22, 32, 46 and 68 according to its kinematic viscosity at 40ºC.

Advantages

♦ Unique non-zinc anti-wear formulation, effectively protecting copper/silver parts, prolonging service life of pump with copper/silver or silver coated parts

♦ Better hydrolytic stability than L-HM anti-wear hydraulic oil, providing good protection even when system suffered from little water pollution

♦ Good environment protecting ability, reducing environment pollution

Performance

The product meets the following specifications:

♦ GB 11118.1-94 (L-HM) Premium

♦ ISO 6743/4 (L-HM)

Applications

♦ Especially suitable for lubrication of high precision hydraulic system with copper/silver parts
