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.



Protect your equipment and the environment at the same time. ENVIRON MV R’s unique formulation gives you all the protection of a
premium industrial hydraulic fluid while also being OECD 301B readily biodegradable to help protect sensitive environments. ENVIRON MV R
combines select, ultra pure, hydrotreated base oils with a premium ashless additive system to provide performance and protection
without compromise.


As an OECD 301B readily biodegradable product, ENVIRON MV R exceeds the requirement of more than 60% biodegradation in 28 days. It can be used in a broad range of applications operating in environmentally sensitive areas, giving you that added peace of mind.


ENVIRON MV R is a low-odour fluid that creates a safer working environment for employees. It is also non-toxic, zinc-free and free of other metal-based additives, which makes it safer for the environment by minimizing the risk of contaminating water resources.



Formulated to perform in a wide temperature range, ENVIRON MV R offers year-round protection in any conditions. Its formulation
blended with high-VI, high-quality base oils and superior additives provides excellent equipment protection in demanding extremes,
making ENVIRON MV R a top performer in a wide variety of operating environments.


Unlike vegetable- and ester-based readily biodegradable oils,
ENVIRON MV R’s unique formulation means you get a long-lasting environmentally friendly product for an exceptional value. It helps protect and extend your equipment’s life, leading to lower costs of operation and ownership.


ENVIRON MV R has better hydrolytic stability and oxidative stability, longer life and greater wear protection than vegetable and synthetic ester products. It also has better seal compatibility than saturated ester products, and this all leads to extending drain intervals, cutting down on maintenance time and saving you money.


ENVIRON MV R is specifically formulated to achieve outstanding performance in the readily biodegradable category. Its unique formulation gives you exceptional oxidative and hydrolytic stability combined with anti-wear performance and rust and corrosion protection.

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.
