Product Data
Hyspin AWS 37
Anti-wear hydraulic oil
Description
Castrol Hyspin AWS 37 hydraulic oil is based upon highly refined mineral oil enhanced with a stabilised zinc additive
system.
Application
Hyspin AWS 37 has been specially formulated to provide good anti-wear and thermal stability performance using proven
additive technology. The careful blend of additives with a high quality base stock ensures that Hyspin AWS 37 has
excellent hydrolytic and oxidative stability while exhibiting a minimal tendency to produce sludge and deposits. In
addition, Hyspin AWS 37 provides corrosion protection to ferrous and yellow metal components found within a hydraulic
system. This is designed for use in industrial hydraulic systems which require antiwear protection such as lightly loaded
gears, variable speed units and bearings. Hyspin AWS 37 is compatible with the most commonly used nitrile, silicone
and fluropolymer seal materials.
Hyspin AWS is classified as follows:
DIN 51502 classification - HLP ISO 6743/4 - Hydraulic Oils Type HM
Hyspin AWS 37 meets the performance requirements of:
DIN 51524 Part 2
Denison (Parker Hannafin) HF-0
AIST (US Steel) 126 & 127
Eaton (formerly Vickers) I-286-S & M-2950-S
Advantages
Hyspin AWS 37 has the following advantages when compared to conventional hydraulic oils:-
Good thermal and oxidative stability. Oxidative stability reduces deposit formation, resulting in a cleaner system.
This can extend the machinery’s operating life.
Excellent anti-wear performance increases wear protection, which can help reduce downtime caused by
unscheduled maintenance.
Good filterability characteristics, including in the presence of water, enables cost savings to be made from
increased filter life and reduced maintenance.
Excellent water separation and hydrolytic stability, measured by industry standard testing. This increases
equipment reliability, helping to prolong the lubricant's life and reduce downtime.
