Rando HDZ ISO 68

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

Rando HDZ ISO 68

Features

Rando HDZ oils 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 oils plate out on the metal surfaces. This plating minimizes metal-to-metal 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.

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 like Hydraulic Oil AW (a lower VI product with VI<105).

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.
