General Purpose R&O Oils

The worldwide marketers of lube oils deal with occasional consolidation of producers. Exxon morphed into ExxonMobil and some legacy brands vanished altogether. The very first non-aqueous lubes were base oils—plain, non-additive base oils. But when the machinery was subjected to moisture, heat and oxygen, the oil oxidized. A few products have achieved a long record of reliable lubricant performance in the lubrication of steam turbines and gas turbines. The centrifugal pump is the most widely used in the chemical and petroleum industries for transferring liquids of all types: raw materials, materials in process and finished products. The working fluid used in the system must have a high degree of oxidation stability, especially in open circuit systems where the expansion tank is open through a breather tube and air can contact the hot oil. Development of lubricated-for-life bearings has brought us electric shavers, kitchen appliances, power tools, automotive electric motors and a host of other conveniences we take for granted.
