Mobil / ESSO UNIVIS HV1 26, J26 Drum


High Hydraulic Oil

UNIVIS™ HVI 26, J26 is a line of premium performance anti-wear hydraulic oils characterised by their unusually high viscosity indexes.

Product Description

Univis HVI is engineered to maintain close viscosity control over wide temperature range applications. Because of their resistance to viscosity change, Univis HVI oils are recommended for hydraulic systems that are subject to wide temperature variations. Many of these systems are sensitive to changes in viscosity of the hydraulic oil, since they depend on uniform viscosity for hydraulic accuracy. They exhibit optimum flow characteristics at sub-zero temperatures and the oils are resistant to shearing and viscosity loss so that system efficiency is maintained and internal pump leakage is minimised at high operating temperatures and pressures. These high quality hydraulic oils also provide very good anti-wear protection for high-pressure vane, piston and gear pumps. The Univis HVI oils are designed with excellent oxidation stability reducing deposit formation and improving pump and valve performance. They were developed in conjunction with the major OEM's to meet the stringent requirements of severe hydraulic systems using high pressure, high output pumps as well as handling the critical requirements of other hydraulic system components.


Features and Benefits of Univis HVI 26 Hydraulic Oil:



Univis HVI oils provide outstanding viscosity control over a
  wide temperature range.

Their excellent oxidation resistance allows extension of oil and
  filter change intervals while assuring clean systems.

Their high level of anti-wear properties and excellent film
  strength characteristics result in exceptional equipment
  performance that not only results in fewer breakdowns but
  helps improve production capacity.

Their controlled demulsibility permits the oils to work well in
  systems contaminated with small amounts of water yet readily
  separate large amounts of water.



The Univis HVI oils provide the following benefits:



Unusually high viscosity index and excellent viscosity control
  characteristics improves machine accuracy and reduces

Very low pour points maintains excellent fluidity conditions at
  low temperatures

Suitable for use in hydraulic equipment operating in very cold
  conditions, such as cold stores and mobile equipment
  operating in very cold climates

High performance and smooth hydraulic operations derived
  from uniform viscosity control, fast air release, very good foam
  control and good water separability

Exceptional rust and corrosion protection reduces the negative
  effects of moisture on system components

Effective oxidation stability reduces deposits and improves
  valve performance

Hydraulic systems critical to uniform hydraulic oil viscosity

  over a wide temperature range

Hydrostatic transmissions and dash pots

They can also be used in fine instruments and other

  mechanisms where power input is limited and increases in

  torque due to the lubricant thickening cannot be tolerated

To reduce deposit formation in equipment where close

  clearance servo-valves are used

Systems where cold start-up and high operating temperatures

  are typical

Systems requiring a high degree of load-carrying capability

  and anti-wear protection

Applications where rust and corrosion protection are an asset

  such as systems where small amounts of water are




Key applications include:


Hydraulic Equipment

Tram & Trains

Car Transmission

Railway Maintance & Construction
