Oil for Vacuum Pumps ULVOIL R Series/Super R Series
R-4/ R-7, and R-80 are petroleum based oil for general use created for both cost effectiveness and quality through hydrogena- tion improvement and high vacuum rectification processing.
R-80 has great general applicability and was developed primarily for small, medium, and large oil rotary pumps.
R-4 and R-7 are cost effective products with high general applicability.
When usinga pump with an extremely high gas load, chemical changes may occur in the oil due to generated heat and chemical composition of the gasses being pumped.
Therefore, it is important to select oil that suits the pump type and operating conditions.
Although fluoride based synthetic oil has stable chemical properties, the Super R series is recommended for even higher quality level of high end lubrication, rust prevention, and sealing.
