Hydraulic Oils are full anti-wear hydraulic fluids designed and developed to be used in industrial power transmission and control systems. They incorporate performance improvement additives to offer greater anti-wear characteristics, oxidation resistance and corrosion protection. For most hydraulic power transmission systems where reciprocating or rotary fluid pumps are used, including reciprocating and axial piston units, rotary gear and vane pumps. The main application for hydraulic fluids will be found in static industrial hydraulic systems and mobile earth moving plant.
