UNIVIS™ EXTRA
Mobil industrial , Canada
High Performance Multi-Grade Hydraulic Fluid
Product Description
UNIform VIScosity; is an essential characteristic for All Season, Multi-Grade hydraulic fluids. Modern high performance hydraulic systems rely on fluids that can resist changes in viscosity, as operating temperatures rise and fall. This is particularly important for outdoor hydraulic systems on stationary and mobile equipment that operate in climates where ambient temperatures can vary widely. UNIVIS™ EXTRA takes All Season performance to a new level of quality and performance, by offering the operating range of a Multi-Grade ISO 22/32 lubricant in a shear stable, high performance hydraulic oil.
Features and Benefits
UNIVIS EXTRA is formulated with carefully selected base oils and a proprietary additive system, designed to provide well balanced performance in mobile and stationary hydraulic equipment. These properties can help to provide long oil life, reduced shear rate and minimized deposit formation in hydraulic systems operating in severe conditions, at high pressure and temperatures. Outstanding foam control and air release properties provide protection for hydraulic systems by helping to prevent cavitation damage and micro dieseling.
| Features | Advantages and Potential Benefits |
| Stable, high-performance anti-wear additives | Helps reduce wear and protects pumps and components and extend equipment life |
| Excellent rust and oxidation control | Oil-wetted parts, ferrous and non-ferrous, are provided with enhanced protection from rust, corrosion and the effects of oxidation |
| High VI, offering the Multi-Grade performance of both an ISO 22 and ISO 32 fluid | Offers additional protection for the pump over a wider operating temperature range |
| Excellent shear stability for stay in grade performance | Enhanced to help provide the required oil film to protect parts, over a long service life. |
| Rapid air release and powerful foam control | Help to prevent destructive cavitation, aeration and resulting heat, and extend oil life |
| Good hydrolytic stability | Designed to resist the decomposition reaction caused by water, that can lead to the formation of acidic and corrosive materials |
| Rapid Demulsification of water | Help to prevent corrosion, maintain viscosity control and extend equipment life |
| Good compatibility with elastomers and seals | Long seal life and reduced maintenance |
Applications
- Industrial and mobile equipment hydraulic systems operating at high pressures and temperatures in critical applications, indoors and outdoors
- Systems where a Multi-Grade hydraulic oil can simplify oil selection, improve low temperature performance and have enough viscosity to operate in warmer ambient conditions
- Systems requiring a high degree of foam control, rust and corrosion protection, load-carrying capability and anti-wear protection
