Multi-Grade Hydraulic Oil

Product Description

UNIVIS™ ULTRA is a premium all season, multi-grade hydraulic fluid, formulated to provide excellent performance over a very wide operating temperature range. UNIVIS ULTRA combines the high temperature viscosity characteristics of an all season ISO VG 46 hydraulic oil with the outstanding low temperature fluidity of an ISO VG 22. The resulting very wide operating temperature range makes UNIVIS ULTRA the ideal choice for severe service in stationary and mobile hydraulic equipment in many applications including; oil field operations, mining, forestry, logging and construction.


Features and Benefits

Features  Advantages and Potential Benefits
Outstanding all season viscosity controlUNIVIS ULTRA is designed to provide start up at temperatures below -40° C, while protecting the pump at operating temperatures above 80° C*      
Potent anti-wear protectionProtects the pump from mechanical wear, thereby helping to extend pump service life and reduce maintenance costs
Outstanding shear stabilityMaintains its viscosity characteristics in severe service, thereby protecting the hydraulic system and providing long service life  
Excellent rust and corrosion protectionProtects against rust and corrosion related surface degradation, thereby reducing damage and associated repair costs
Control or foam and airRapidly releases foam and air, thereby reducing component wear, heat, and cavitation, helping to improve component life. 
Rapid Demulsification of waterSheds water rapidly, helping protect the system from rust and corrosion and protect components from wear.
Excellent oxidation stabilityResists the formation of sludges and varnish, thereby providing a cleaner system and enabling reduced maintenance and longer component and filter life. 

*Based on recommended maximum start up viscosity of 9300 cP and a minimum fluid viscosity requirement of 13° C at normal operating temperature



  • Recommended in stationary and mobile hydraulic systems where the ambient operating conditions vary widely, from very cold to hot.
  • Recommended as a general purpose lubricant, where a multi-grade ISO 46 anti-wear type lubricant is recommended, ie: pumps, bearings, circulating systems.
