Ashless anti-wear hydraulic oil

1. Features:
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.
Unique non-zinc anti-wear formulation, effectively protecting copper or 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.

2. Application:
Especially suitable for lubrication of high precision hydraulic system with copper/silver parts.

3. Performance:
The product meets GB11118.1- 94 specification.
