Description:

Rando HDZ oils are formulated with premium base oil technology and designed to give robust protection to hydraulic pumps.

Customer Benefits:

Rando HDZ oils deliver value through:

• High oxidation stability — Long service life in high pressure service.

• Protection against rust and corrosion — Gives excellent protection against corrosion of both copper and steel. Passes the ASTM D665A distilled water rust test and ASTM D665B salt water rust test.

• High viscosity index — Minimum change in viscosity over a wide range of operating temperatures.

• Foam inhibition — Contains special foam suppressant.

• Excellent antiwear properties — Provides excellent wear protection.

• Good stability — in the presence of water in the ASTM D2619 Hydrolytic Stability Test and in the presence of copper and steel in the MAG Cincinnati Machine Thermal Stability Test.

• Fast water separation — Protects against rust problems by fast release of water.

• Good filterability — Excellent thermal and hydrolytic stability helps prevent formation of deposits which may interfere with filtration in equipment having close tolerances.

Applications:

Rando HDZ oils are versatile lubricants available in multiviscosity ISO 15, 22, 32, 46, 68, and 100 grades. The multiviscosity feature promotes even and continuous power transmission over a wide temperature range with a minimum of shudder, and maximum accuracy. They are recommended for hydraulic or circulating oil systems, including marine on-deck machinery, hydraulic actuated loading bins, or equipment that require a wider operating temperature as compared to a single viscosity grade oil.
