High Viscosity Index Hydraulic Fluids

Product Description

UNIVIS™ HVI 13 and 26 have been formulated to provide outstanding viscosity control in applications where ambient temperature can vary widely, from very cold to warm. In addition to their wide operating range, these fluids provide excellent wear protection, potent rust and corrosion protection, rapid foam and air release and outstanding resistance to oxidation. These performance features help to provide the protection required to keep hydraulic systems operating more efficiently over a wide operating temperature range.


Features and Potential Benefits

UNIVIS HVI 13 and 26 are designed to deliver the following features and potential benefits:

FeaturesAdvantages and Potential Benefits
High Viscosity index – wide operating temperature rangeOutstanding fluidity for low temperature start-ups, improved viscosity protection for pump components operating at both at low and high temperatures 
Effective foam control and air release Rapid air release, which helps to protect components from cavitation, wear and excess heat
Outstanding oxidation stabilityHelps keep components clean and free from sludges and varnishes that reduce hydraulic efficiency and operating life. Can help to extend oil life and reduce maintenance requirements
Excellent protection against rust and corrosionHelps to improve component life and reduce failures associated with rust and corrosion damage to system components 
Potent Anti-Wear protectionComponents wear rates are reduced by anti-wear and this can lead to improved component life and reduced maintenance
