Klüberbio RM2-100, 2-150
Klüberbio RM 2 oils were developed for the lubrication of propeller bushes made of white metal and propeller shaft seals. Biodegradable, non-toxic stern tube oils
– Comply with the requirements for Environmentally Acceptable Lubricants as defined in Appendix A of the EPA 2013 VGP (Vessel General Permit)
– Biodegradable and not toxic to marine organisms reducing environmental impact in the event of leakage
– FKM elastomers available from leading propeller shaft seal manufacturers are compatible and approved for use with Klüberbio RM 2 oils to prevent leakage and contamination
Klüberbio RM 2 oils are readily biodegradable oils for stern tubes based on synthetic ester oil showing good ageing and oxidation stability.
Their biodegradability acc. to OECD 301 F is ≥ 60 % after 28 days. The oils are rated as non-toxic according to the tests OECD 201(EC50), OECD 202 (EC50) and OECD 203 (LC50). In all three tests, EC50/LC50 is > 1,000 mg/l.
As the lubricants are readily biodegradable and contain carefully selected raw materials, oil loss or leakage are less dangerous to the environment. Klüberbio RM 2 oils contain > 90 % of renewable raw materials and bear the European Ecolabel.
In general, Klüberbio RM 2 oils are miscible with mineral oil based stern tube lubricants. 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 stern tube with the Klüberbio RM 2 oil.
Klüberbio RM 2 oils need to be approved by the OEMs of the equipment. In case the oil has not yet been approved or the equipment's specification has been changed - e.g. type, design or material of the sealing - we recommend consulting the OEM prior to the oil change.
Owing to the many different elastomer compositions of seals we recommend - prior to series application - checking the compatibility and other influencing factors that are relevant for the application with the component under conditions similar to practice.
