Rando HDZ is a proven performance multi-viscosity antiwear hydraulic fluid designed to offer robust protection at 1000 pounds per square inch (PSI) where surge pressures may increase metal-to-metal contact and wear, by effectively plating out metal surfaces in vane-, piston-, and gear-type pumps.
Rando HDZ is formulated with premium Group II base oil technology in combination with reliable additives to offer corrosion, oxidation, foam and aeration resistance, with dependable shear stable viscosity index (VI) improver performance, helping optimise system protection.
In laboratory testing, Rando HDZ provided up to 5% improvement in overall hydraulic pump efficiency when compared with typical monograde hydraulic oil with VI<105 performance.
Product Highlights
- Formulated for wide temperature use
- Designed to protect under load
