ENVIRON™ MV R Hydraulic Fluid


ENVIRON MV R are readily biodegradable, non-toxic hydraulic fluids and therefore, particularly suited for hydraulic applications in environmentally sensitive locations. ENVIRON MV R hydraulic fluids are premium multigrade antiwear hydraulic fluids designed for year-round use in both mobile and stationary heavy-duty hydraulic systems operating in wide extremes of temperatures.

ENVIRON MV R hydraulic fluids use select, ultra pure, hydrotreated base oils. By removing the impurities that can hinder the performance of competitive conventional oils, and blending with a premium ashless additive system, ENVIRON MV R delivers exceptional performance and protection without compromise.

Features & Benefits

  • Readily biodegradable

    • Greater than 70% biodegradability within a 28-day period according to OECD 301B, safely above the 60% minimum requirement for readily biodegradable classification

  • Non-toxic and very low odour

    • Not acutely toxic to fish, daphnia or algae according to the United Nations Globally Harmonized System (GHS) criteria

    • ENVIRON MV R contributes to a cleaner, safer and more pleasant work environment

  • Reduced occurrence of water contamination by metals

    • Transition metal content in ground water or waste water streams is a concern because it bio-accumulates in the food chain. ENVIRON MV R is ashless and does not contain any metal-based additives.

  • Recyclable

    • Can be recycled and reclaimed, unlike vegetable oil based products which have to be incinerated or land farmed

  • Excellent anti-wear, rust and corrosion protection

    • Designed to deliver excellent long-lasting protection against wear, rust and corrosion

    • Exceeding the performance requirements of conventional anti-wear hydraulic fluids or vegetable- and unsaturated ester-based products

  • Use under wide extremes of temperature

    • Allows hydraulic systems to start up at temperatures as low as -36°C / -33°F (ENVIRON MV R 32)

    • Provides excellent lubrication of hydraulic components at high operating temperatures

    • Unlike vegetable oils, does not thicken and gel at moderately low temperatures

  • Superior oxidation and thermal stability compared to competitive vegetable oil based, synthetic ester products and conventional hydraulic oils

    • Longer oil life, which extends the time between oil changes​

    • Helps reduce sludge and varnish deposits to ensure smooth, reliable operation of hydraulic valves and actuators

  • Excellent water separability and hydrolytic stability

    • Eases water removal and helps preserve the performance of the oil over a longer period of time​

  • Excellent foaming resistance and air release performance

    • Provides consistent lubrication film to ensure equipment protection and performance​


ENVIRON MV R hydraulic fluids are formulated for both indoor and outdoor use in piston, gear and vane hydraulic pumps found in industrial plant and mobile equipment used in environmentally sensitive areas and is well suited for hydraulic systems in hydroelectric dam operations. When ENVIRON MV R is used in systems equipped with fine porosity filters down to 3 microns, there is no loss of additives or filter plugging.


ENVIRON MV R fluids are approved against the following hydraulic OEM specifications:

  • Parker Denison HF-0, HF-1, HF-2

  • Eaton Brochure 03-401-2010 Rev 1


ENVIRON MV R fluids meet the requirements of the following industry standards:

  • DIN 51524 Part 3 HVLP

  • ISO 11158 HV


ENVIRON MV R fluids are also suitable for use where Bosch Rexroth RDE 90220 specification is required and in equipment manufactured by Sauer-Danfoss, Racine, Oilgear, Hydreco, Dynex and others.


ENVIRON MV R does not contain zinc-based antiwear additives so it can be used in hydraulic pumps with silver bearings, such as Lucas pumps because it will not displace the silver in these bearings.
