Hido HV is a range of premium mineral-based hydraulic oils available in ISO viscosity grades 32, 46, and 68, formulated with advanced anti-wear and anti-corrosion additives for reliable hydraulic system performance. These HVLP-type hydraulic oils feature a high viscosity index, meaning they maintain more consistent viscosity across a wider temperature range compared to standard HLP hydraulic oils, making them the preferred choice for systems that operate in environments with significant temperature fluctuations.

The high viscosity index provides important practical benefits. In cold conditions, Hido HV oils flow more readily than standard hydraulic oils, enabling faster system response and reducing energy consumption during startup. In warm conditions, they retain higher viscosity than conventional oils, maintaining the protective oil film and volumetric efficiency of pumps and actuators. This temperature stability is particularly valuable for mobile hydraulic equipment that operates outdoors across seasonal temperature variations.

The anti-wear additive technology provides effective protection for moving elements in all hydraulic pump types, including vane, axial piston, radial piston, and gear pumps. This protection extends pump service life and maintains system efficiency by minimizing internal leakage. The oils are formulated for excellent material compatibility — they do not adversely affect non-ferrous metal components and are compatible with standard rubber and plastic sealing materials.

Beyond hydraulic applications, Hido HV oils are also suitable for lubrication of small, lightly loaded enclosed gear transmissions. The three viscosity grades allow optimal selection for each application: ISO 32 for lighter systems, ISO 46 as the most universal grade, and ISO 68 for heavier loads. Hido HV is a premium choice for industrial, mobile, and agricultural hydraulic systems requiring enhanced temperature performance.
