PRODUCT DESCRIPTION

Chevron Hydraulic Oils AW are designed to give excellent hydraulic pump protection.

CUSTOMER BENEFITS

Chevron Hydraulic Oils AW deliver value through:

• Good oxidation stability — Provide good service life in high pressure service.

• Rustandcorrosionprotection—Giveexcellent protection against corrosion of both copper and steel, and passes the ASTM D665A distilled water rust test and ASTM D665B synthetic sea water rust test.

• Minimumviscositychangeoverawide temperature range.

• Goodfoaminhibition—Containspecialfoam suppressant, minimizing both foaming and aeration problems.

• Excellentantiwearproperties

• Meetsmajorpumpmanufacturer’s requirements — ISO 32, 46 and 68 meet the requirements of leading hydraulic pump manufacturers for antiwear-type hydraulic fluids in both vane- and piston-type pumps.

• Goodstabilityinthepresenceofwaterby ASTM D2619 Hydrolytic Stability test and the Denison hybrid T6H20C Wet Pump test.

• Goodthermalstabilityinthepresenceofcopper and steel by the MAG Cincinnati Machine Thermal Stability, Procedure A, test.

• Fastwaterseparation—Minimizerustproblems by fast release of water.

FEATURES

Chevron Hydraulic Oils AW are formulated with refined paraffinic base oils. They provide excellent antiwear protection, oxidation and corrosion inhibition, as well as foam and aeration suppression. All grades have excellent demulsibility characteristics.

Hydraulic systems, due to the nature of their operation, experience accelerated wear unless they are protected by clean, high quality antiwear hydraulic oils. Surging pressures in pumps and valves can increase metal-to-metal contact unless antiwear protection is present. The antiwear additives in Chevron Hydraulic Oils AW create a protective film on the metal surfaces. This protective film minimizes metal-to-metal contact, which is most severe in vane- and gear-type pumps. As hydraulic pressures increase over 1000 psi, the need for antiwear protection increases proportionally.

APPLICATIONS

Chevron Hydraulic Oils AW are versatile lubricants available in ISO viscosity grades 32, 46 and 68.

ISO 32, 46 and 68 grades are most commonly used for hydraulics with vane-, piston-, or gear-type pumps, especially where pressures exceed 1000 psi. They can also be used to lubricate lightly loaded reciprocating compressors.
