EERSTA HYDRA HVLPD 46 ZF is a high-grade zinc-free, detergent 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 wear-preventing properties
• very good activity against corrosion
• good stability against oxidation
• very good detergency and dispersion
• ability to absorb a certain amount of water without becoming turbid and without any detrimental effects on its other properties
• very good deaerating and foam suppressing properties
• good compatibility with seals and gaskets made from synthetic material
• low pour point

This detergent hydraulic fluid is suitable for heavy duty hydraulic systems of earthmoving equipment and of permanent installations, where small amounts of water can penetrate into the system 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.
