Your benefits at a glance

– Comply with the requirements for Environmentally Acceptable Lubricants as defined in Appendix A of the EPA 2013 VGP (Vessel General Permit)
– Completely biodegradable, non-toxic products reducing environmental impact in the event of leakage
– Enable start-up of hydraulic systems at very low temperatures and generally use over a wide temperature range due to very good viscosity-temperature behaviour and low solidification point

Your requirements – our solution

Klüberbio LR 9 oils are completely biodegradable, eco-friendly hydraulic fluids based on synthetic ester oils. These oils contain >90 % of renewable raw materials and comply with the European Ecolabel.

The EU Ecolabel is a label of environmental excellence that is awarded to products and services meeting high environmental standards throughout their life-cycle: from raw material extraction, to production, distribution and disposal.

Attaining EU Ecolabel certification provides ship owners and/or operators with independent assurance that the product achieves the U.S. EPA’s requirements for classification as an Environmentally Acceptable Lubricant (EAL). Therefore, these high-performance lubricants meet the biodegradability, minimally toxic, and non-bioaccumulating standards set in Appendix A of the U.S. EPA’s VGP (Vessel General Permit). In addition, Klüberbio LR 9 oils meet or even exceed the minimum requirements stipulated in ISO 15380 and Bosch Rexroth RE 90221-01.


Klüberbio LR 9 oils are intended for applications in mobile hydraulic systems, e.g. in the marine and offshore industries as well as for use in the building and water engineering sectors.

They are also preferred in stationary hydraulic equipment operating in ecologically sensitive environments, e.g. in hydroelectric power plants and waterway locks.

Application notes

Klüberbio LR 9 oils meet ISO 15380 requirements in terms of compatibility with standard reference elastomers. Nevertheless,due to the large variety of materials available, compatibility with seals and paint coatings should be verified. In general, Klüberbio LR 9 oils are miscible with hydraulic oils based on mineral oil. However, a miscibility test should be performed in order to totally rule out the possibility of an incompatibility between different additives. Prior to changeover, we recommend flushing the hydraulic system with the Klüberbio LR 9 oil.
