DESCRIPTION :
This oil has been reformulated to provide trouble free lubrication in new sophisticated hydraulic
equipment such as NC Plastic Extrusion Machines and equipment incorporating filteration down to 5
microns. These machines are particularly prone to spool valve sticking and filter clogging.
Hyspin VG 68 incorporates a low ash additive package which makes it superior to conventional
antiwear hydraulic oil through :-
* Minimum of metallic additive and therefore ash deposits.
* Less generation of particle matter.
* Unlike normal zinc containing hydraulic oils, is completely stable (non sludge
forming) in presence of moisture.
* Non aggressive to copper, silver and their alloys.
* More thermally stable under high temperatures.
* Better frictional characteristics. Conventional Zinc containing oils tend to produce
stick-slip.
SUMMARY OF FEATURES :
Higher level of resistance to : * Wear
* Oxidation
And yields excellent : * Hydrolytic stability
* Filterability
* Demulsibility
N.B.
Whilst special precautions are taken during manufacture of Hyspin VG 68 to prevent particulate and
metal additive contamination, it is advisable when initial filling new machines to flush system, pump
the Hyspin VG 68 out again into the drums in which it was supplied through a 5 micron filter, then
pump the oil back into the machine again through 5 micron filter.
