- The oils are designed for energy transmission in plants requiring the use of a hydraulic fluid. The oils also provide adequate lubrication by creating a strong lubricant film that withstands high loads between the sliding parts of high-pressure hydraulic systems.
- AGIP OSO oils have very good anti-wear properties, as illustrated by typical test results :
- Vane and ring wear in the Vickers test around 35 mg
- The higher grades (OSO 46-150) passes the 12th stage of the FZG test, while the lower grades passes 11th stage.
- They have extremely good oxidation resistance and stability even when subjected to unusually high thermal stresses, this property minimizes sludge and deposit formation, thus preventing blocking of ports, valves, and controls, while guaranteeing that the oil remains properly fluid.
- Maintenance costs are therefore reduced and the useful service life of the oil is extended.
- The high Viscosity index of all grades minimizes changes in viscosity throughout the normal range of operating temperatures, thus ensuring constant flow, low friction loss, and good hydraulic efficiency, while protecting against the possibility of cavitation.
- Their outstanding anticorrosion and antirust properties inhibit the oxidation of internal surfaces of hydraulic circuits and therefore prevent operating difficulties and breakdown of the oil caused by metallic oxides that would otherwise form within the machinery.
- Their good demulsibility prevents the formation of a stable emulsion between the oil and any water that enters the system through leakage or condensation. The fluids therefore maintain their lubricating power and anticorrosion performance even under these circumstances.
- Their antifoam properties and their ready release of entrained air prevent difficulties with pumps and controls which can cause irregularities in performance and other problems arising from the compressibility of air bubbles.
- They show a very high filterability, they are suitable for very fine filters (3 micron up to ISO VG 68)
