EERSTA HYDRA HM series is a high grade EP hydraulic oil based on selected solvent refined base oils having a natural viscosity index, under addition of additives to obtain the following properties:

• excellent wear-preventing properties
• very good activity against corrosion
• excellent stability against oxidation
• excellent demulsification properties
• robust deaerating and foam suppressing properties
• good compatibility with seals and gaskets made from synthetic material
• low pour point

May be used for heavy duty hydraulic equipment as well as for light duty gearboxes and bearings. These hydraulic oils may also be used for lubrication systems, general lubrication and vacuum pumps (with the exclusion of turbines). These fluids are NOT compatible in systems, containing parts or equipment with a silver lining.
