Rando® HD oils are formulated with premium base oil technology and designed to give robust protection to hydraulic pumps in mobile and stationary systems.

Rando HD oils deliver value through:

• Long equipment life — Special antiwear additive package minimizes wear by protecting surfaces when load causes breakdown of the lubricant film.

• Minimized downtime — Effective rust and oxidation inhibitor system helps prevent the production of abrasive particles from rust formation,
and deposits, varnishes and sludges from oil breakdown, which can damage equipment surfaces and seals, and block filters prematurely.

• Smooth operation — Good hydrolytic stability and water separation characteristics promote excellent filterability in the presence of water
contamination. Good anti-foam and air release help ensure smooth operation and system efficiency.

• Optimal oil service life — High oxidation stability resists oil thickening and deposit formation in service, minimizing the possibility of an unscheduled
change of hydraulic fluid.


Rando HD ISO 32, 46, and 68 are formulated with Group II base stocks.

Rando HD ISO 100, 150, 220, and 320 are designed for lubricant applications requiring an AGMA R&O gear oil lubricant in the applicable viscosity grade.

Rando HD oils provide excellent:

• antiwear protection

•oxidation and corrosion inhibition

• foam and aeration suppressionUnder moderate loads and temperatures, the high viscosity index of Rando HD oils help ensure good film
strength between metal surfaces and is further enhanced by antiwear additive protection.

Rando HD ISO 10 and 22 can be used as spindle lubricants where zinc-free oils are not a requirement.

Rando HD ISO 32, 46, or 68 are recommended for:
• vane-, piston-, or gear-type pumps, especially where pressures exceed 1000 psi

• lightly loaded reciprocating compressors Rando HD ISO 100, 150, 220, or 320 are recommended for applications where AGMA rust andoxidation inhibited oils are required:

• hydraulic equipment reduction gears where EP is not

• plain and antifriction bearings

• circulating oil systems

Rando HD oils are approved for:
• Eaton-Vickers 35VQ25A pump, M-2950-S
(Mobile) and I-286-S (Stationary) (ISO 32, 46, 68)
• Parker Hannifin (Denison) HFO, HF1, HF2,
T6H2OC (ISO 32, 46, 68)
• Bosch Rexroth (ISO 32,46, 68)
