Yes, they are compatible with NBR (Buna), HNBR (hydrogenated Buna), AU (Polyurethane) and FKM (Viton).
It will depend on the specific oil, operating system temperature and pressure. EnviroLogic® oils usually last as long as or longer than comparable petroleum based fluids.
Key fluid performance indicators measured in oil sampling and analysis include:
- Stay-in-grade kinematic viscosity @ 40°C
- TAN increase
- Water contamination
- Additive/wear elements
- Particle counts
Always follow the original equipment manufacturer’s suggested oil change frequency requirements or conduct regular oil sampling and analysis to determine exactly when oil needs to be changed. RSC Bio Solutions works closely with our customers to develop oil sampling and analysis programs. Please contact your sales representative to learn more.
The flush and fill procedure to convert to EnviroLogic® products is as simple as the cleaning and maintenance procedure you currently use for scheduled care of your equipment. Although it is not required, we recommend flushing the hydraulic system with EnviroLogic® BioFlush before filling with the appropriate hydraulic fluid.
A residual amount of petroleum oil will remain in the sump of the equipment. This will have no effect on the performance of the EnviroLogic® fluid.
