TOPGATEX Hydraulic Oil ISO 37 AW is designed to give maximum protection to hydraulic pumps in high performance industrial applications as well as in environmentally sensitive areas.
TOPGATEX ISO 37 is formulated with base stocks and an ash less ("zinc-free") additive system that provides superior oxidation stability, water separability, foam suppression, and protection against wear, rust and corrosion.
TOPGATEX Hydraulic Oil has been specially formulated to provide good anti-wear and thermal stability performance using the very latest additive technology. The careful blend of additives with a high quality base stock ensures that TOPGATEX Hydraulic Oil has excellent hydrolytic and oxidative stability while exhibiting a minimal tendency to produce sludge and deposits. In addition, TOPGATEX AW provides corrosion protection to ferrous and yellow metal components found within a hydraulic system.
This range is designed for use in industrial hydraulic systems which require anti-wear protection. It is also suitable
For other duties in which lubricants of high oxidation stability and lubrication performance are required, such as
Lightly loaded gears, variable speed units and bearings.
