EERSTA HYDRA HV ZF SERIES is a high-grade zinc-free, multigrade EP hydraulic oil based on selected solvent refined base oils having a natural viscosity index, under addition of additives to obtain the following properties:

• high and stable viscosity index
• excellent protection against wear
• 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 seals and gaskets made from synthetic material
• low pour point

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 range. This hydraulic fluid may also be used for lubricating systems, general lubrication and vacuum pumps (with the exclusion of turbines). This oil can be used in systems with silver parts.
