590 MULTI-VISCO HYDRAULIC OIL

SPEC'99 – 590, SPECIALLY FORMULATED FROM SOLVENT REFINED PARAFFINIC BASE HYDRAULIC OIL, FORTIFIED WITH EXCLUSIVE ANTI - WEAR ADDITIVE “ SPEC - GX ”, FOR LONG SERVICE LIFE.

FEATURES:

SPEC'99 - 590 , is highly viscous, with greater film strength to ensures constant pressure, high volumetric efficiency.

* High VI provide excellent hydraulic response at both high and very low ambient temperatures

* Superior oxidation control to prevent oil thickening

* Foam dispersion to prevent pumps cavitations

* Effective demulsification, prevent power - robbing phenomena

* Excellence anti - wear properties to fight friction

* Superior corrosion inhibited, multi - metal compatibility

* High aniline points, minimum effects on oil seal materials

* Universal applications, inventory reduction

PRODUCT INFORMATION

SPEC'99 - 590 remain effective performance even encounter the most difficult and tough working conditions. Exceeded all major hydraulic pump manufacturer's specifications.

HIGH VISCOSITY INDEX : SPEC'99 - 590 contain an effective VI improver which provide viscosity stability in the hydraulic system that subjected to wide ambient and system operating temperature range.

OXIDATION CONTROL : The oxidation additives help to prevent oil thickening, reduce sludge and varnish formation, that improved lubricant life and drain cycles, which is generally result in noticeable reduction on oil consumption.

FOAM DISPERSION : Foaming is one of the major cause of surging and loss of power in hydraulic system, the effective foam dispersion inhibitors help to disperse foams quick and maintain power transmission in peak level even during the “ mid - day ”.

DEMULSIFICATION EFFECTIVENESS : SPEC'99 - 590 contains effective demulsifier to fight power - robbing phenomena, especially during the present of condensation of water within the oil reservoir.

ANTI - WEAR ADDITIVES : SPEC'99 - 590 fortified with an exclusive developed additive

“ SPEC - GX ” provide an unique film strength, lessen metal - to - metal contact, minimize friction and wear, cooler operating temperatures and longer life for hydraulic components and the lubricants itself.

CORROSION INHIBITOR : SPEC'99 - 590 has a very low pH, and therefore there is no acid build - up, minimize corrosion effects on metal parts and oil seal materials in the entire hydraulic system.

LUBRICITY : SPEC'99 - 590 is manufactured from high solvent refined paraffin base oil that provide excellent lubricity to the friction - prone areas, eliminating premature wear.

VERSATILITY : Recommended for all hydraulic system regardless of the operating pressure,

hydraulic pump designs including vane, gear, and axial and radial piston pumps, widely use in

machine tools, presses, die-casting machines, circulating systems and hydraulic control systems. Also suitable for mobile construction equipment.
