Rando® HDZ

описание:

Rando HDZ are high performance multi-viscosity hydraulic fluids formulated with premium base oil technology. As hydraulic pressures increase over 1000 psi, the need for anti-wear protection increases proportionally. Rando HDZ is designed to promote robust wear protection where surge pressures can increase metal-to-metal contact in vane-, piston-, and gear-type pumps, through the effective plating out of metal surfaces. 

Rando HDZ offers reliable corrosion protection, durable oxidation resistance, foam and aeration suppression as well as dependable shear stable viscosity index improver performance, helping maintain optimum system protection. 

In laboratory efficiency testing, Rando HDZ Oils provided up to 5% improvement in overall hydraulic pump efficiency when compared to a typical monograde hydraulic oil with VI<105. 

Customer benefits

• Promotes robust oxidation resistance, helping maintain system protection across a wide range of operating temperatures
• Reliable shear stable VI improver contributes consistent system operation throughout a wide operating temperature spectrum
• Offers durable wear protection in vane, gear and piston pumps, helping reduce maintenance and increase system uptime
• Effective rust and corrosion inhibitors aid reliable system protection, reducing maintenance and downtime
• Foam suppression performance assists rapid release of entrained air, and offers water separation, helping improve system reliability
• Aids dependable long-term filterability and system reliability in the presence of water

Applications

• Rando HDZ fluids are versatile lubricants available in multi-viscosity ISO 15, 22, 32, 46, 68, and 100 grades
• The multi-viscosity feature promotes even and continuous power transmission over a wide temperature range offering 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 requires a wider operating temperature as compared to that of a single viscosity grade oil
• 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)
• Always confirm that the product selected is consistent with the original equipment manufacturers recommendation for the equipment operating conditions and customer's maintenance practices

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
