Chevron Rando® HDZ 15, 22, 32, 46, 68, 100

Rando® HDZ are formulated with premium base oil technology and designed to give robust protection to hydraulic pumps. CUSTOMER BENEFITS Rando HDZ 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. FEATURES Rando HDZ incorporate antiwear additives, oxidation and corrosion inhibitors, foam and aeration suppressants, and a shear stable viscosity index improver. 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 Rando HDZ plate out on the metal surfaces. This plating minimizes metal-tometal contact, which is most severe in vane-, piston-, and gear-type pumps. As hydraulic pressures increase over 1000 psi, the need for antiwear protection increases proportionally. APPLICATIONS Rando HDZ 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. Rando HDZ ISO 32, 46, and 68 meet major hydraulic pump manufacturers’ requirements including: • Bosch Rexroth Racine Model S • Eaton-Vickers I-286-S, M-2950-S, 35VQ25A • DIN 51524-3 • MAG Cincinnati, Cincinnati Machine P 68 (ISO 32), P 70 (ISO 46), P 69 (ISO 68) • Parker Hannifin (Denison) HF0, HF1, HF2 Rando® HDZ — Continued Always confirm that the product selected is consistent with the original equipment manufacturer's recommendation for the equipment operating conditions and customer's maintenance practices. 22 February 2010 IO-174 12-12 In a clean, dry environment, Rando® HDZ ISO 15, 22, 32, 46, 68, and 100 typically meet a dielectric strength of 35 kV1 (ASTM D8772). They may not be suitable for extremely high shearing pumps or equipment. Refer to the service manual of the equipment to ensure that the minimum fluid viscosity requirements are met at the highest operating temperature. Please consult with your equipment manufacturer if equipment is operating outside normal operating conditions. Do not use in high pressure systems in the vicinity of flames, sparks and hot surfaces. Use only in well ventilated areas. Keep container closed.
