Univis HVI 13 Hydraulic Oil

The Mobil Univis HVI 13 is a premium performance anti-wear hydraulic oil designed with an exceptionally high viscosity index. Its primary characteristic is the ability to maintain close viscosity control over wide temperature applications, making it highly suitable for hydraulic systems that experience significant temperature fluctuations. Many such systems rely on uniform viscosity for accuracy, and the Univis HVI 13's resistance to viscosity change ensures this precision is maintained. This hydraulic oil exhibits optimal flow characteristics even at sub-zero temperatures and is resistant to shearing and viscosity loss. This ensures that system efficiency is maintained and minimizes internal pump leakage during high operating temperatures and pressures. It provides excellent anti-wear protection for high-pressure vane, piston, and gear pumps. Developed in collaboration with major OEMs, it meets the stringent demands of severe hydraulic systems that utilize high-pressure, high-output pumps and other critical system components. Key features include outstanding viscosity control, excellent oxidation resistance that allows for extended oil and filter change intervals, and high-level anti-wear properties with excellent film strength. These contribute to exceptional equipment performance, fewer breakdowns, and improved production capacity. Its controlled demulsibility allows it to function effectively in systems with minor water contamination while readily separating larger amounts of water. The oil also offers exceptional rust and corrosion protection and effective oxidation stability to reduce deposits and improve valve performance.
