SOLAR Optima Series Hydraulic Oils AW 320 API ISO

Description

Solar Hydraulic Oil ISO AW 320 is a high-performance, heavy-duty anti-wear hydraulic oil formulated from top-tier refined mineral base oils combined with an advanced additive system. Designed to deliver maximum protection under extreme load and pressure, this oil ensures superior wear resistance, oxidation stability, and thermal endurance. ISO VG 320 is ideally suited for heavily loaded hydraulic systems and circulation systems, especially in industrial environments where slow-moving, high-load components demand extra film strength and reliability.

Available API

ISO

Applications

Heavy-load hydraulic systems in steel mills, press systems, and marine deck equipment.
Suitable for industrial machinery where ISO VG 320 viscosity is specified for slow-speed, high-pressure hydraulic circuits.
Gear-type, vane-type and piston-type hydraulic pumps operating under severe service conditions.
Circulation systems and oil-lubricated plain bearings in industrial plants.

Key Features & Benefits:

Outstanding Anti-Wear Protection
Reduces friction and wear in pumps, motors, and valves, extending component life even in harsh, high-load applications.
Excellent Oxidation & Thermal Stability
Withstands high operating temperatures, reducing sludge and deposit formation and extending oil change intervals.
Superior Rust & Corrosion Protection
Shields metal surfaces from rust and corrosion even in wet or humid operating conditions.
Exceptional Air Release & Anti-Foaming Characteristics
Minimizes air entrapment and foam to ensure smooth, efficient and reliable hydraulic system operation.
Rapid Demulsibility
Facilitates fast water separation, preventing emulsions and maintaining consistent hydraulic performance.

Health & Safety:

Avoid prolonged skin contact. Use gloves during handling. In case of contact with skin or eyes, wash immediately with clean water. Dispose of used oil responsibly and consult the Material Safety Data Sheet (MSDS) for further information.
