Description

Rando® HDZ oils are high-viscosity, high-performance, anti-wear hydraulic oils, formulated specifically to cater to the widely varying operating temperatures in the marine environment. These oils are blended from high-viscosity index lubricating oil stocks and several specially selected additives designed to give robust protection to hydraulic pumps. Rando HDZ meets the requirements of major hydraulic equipment manufacturers for rust and oxidation inhibited hydraulic fluids, as well as for EP or anti-wear hydraulic fluids.

Recommended Uses

Rando® HDZ oils are recommended for use in all shipboard hydraulic machinery and specifically for hydraulic equipment used under extreme operating temperatures such as deck machinery. The multi-viscosity feature promotes even and continuous power transmission over a wide temperature range with a minimum of shudder, and maximum accuracy.

Performance Benefits

1. Anti-Wear and EP Properties

Extends the life of hydraulic pump and motor parts in heavy-duty service and helps protect against destructive wear under overload conditions.

2. Ultra-High Viscosity Index

Contains a specially selected high shear-stable viscosity index improver, which gives the lubricant a superior operating temperature window, even under high shearrate conditions. Rando HDZ oils provide real “crossgrading” benefits and stay in grade, even when subjected to the shearing condition of high-speed, high- pressure hydraulic systems in severe service.

3. Low Pour Point

Remains liquid at low operating temperatures.

4. Oxidation Stability

High oxidation stability helps ensure long life and prevent accumulation of sludge and deposits.

5. Corrosion Protection

Helps protect against rusting of close-fitting hydraulic system parts and prevents the regeneration of abrasive rust and corrosion.

6. Water Resistance

Water-separation characteristics assure speedy removal of water from leaks and condensation.

7. Foam Resistant

Combined with selected foam inhibitors, resists foaming, thus preventing accumulation of surface foam at high-oil circulation rates.

8. Filterability

Rando HDZ oils show good filterability properties even in the presence of water. They passed the AFNOR NFE 48 dry and wet filterability tests.
