DOB HYDRA H46, H68
Description
A high-grade EP-multigrade hydraulic oil based upon carefully selected solvent-refined base oils under addition of additives to obtain the following properties:
- a high and stable viscosity index
- excellent wear-preventing properties
- a very good activity against rust and corrosion
- excellent stability against oxidation
- very good demulsification properties
- very good deaerating and foam suppressing properties
- good compatibility with sealings and gaskets made from synthetic material
- very low pour point
Application
This hydraulic fluid is of tailor-made quality for heavy-duty hydraulic systems of earthmoving equipment and of permanent installations that have to work under high pressures over a wide temperature-rage. This fluid is not compatible in systems, containing parts or equipment with a silver lining
