Castrol Hyspin Heavyduty hydraulic oil range is based upon highly refined mineral oil enhanced with a stabilized zinc additive system.
Castrol Hyspin Heavyduty hydraulic oil range has been formulated to provide good anti-wear and thermal stability performance using a stabilized zinc additive system. Hyspin Heavyduty hydraulic oil range has excellent hydrolytic and oxidative stability while exhibiting a minimal tendency to produce sludge and deposits. In addition, Hyspin Heavyduty hydraulic oil range 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.
Hyspin Heavyduty grades meet the requirements (for appropriate viscosity grade) of : DIN 51524 Part 2
Advantages
Good thermal and oxidative stability leads to longer operating life, reduction in lubricant costs and minimizes deposit formation giving a cleaner system.
Excellent anti-wear performance gives wear protection and reduces downtime from unscheduled maintenance.
Excellent water separation and hydrolytic stability means reduced down time through prolonged lubricant life and increased equipment reliability.
