Oil Mist System Lubricants Pure oil mist lubrication eliminates the need for oil rings or slinger disks. There is no liquid oil groove in the bearing housing, so the term "dry oil groove" is often used to describe modern oil mist process lubrication. Use of ISO VG 68 and VG 100 mineral or synthetic oils, although properly formulated ISO VG 32 synthetic oils (rather than mineral oils) will serve most pump bearings as well as types of rolling bearings in electric motors.

The accumulated experience of pumps and motors proves the feasibility and cost-effectiveness of modern plant-wide oil mist systems. When using oil mist on problem pumps, the typical payback period is typically less than one year.

By changing different oils, using different lubricant application methods or switching lubricant application methods and lubricant types at the same time, bearing friction can be reduced. With the joint efforts of a multinational lubricant manufacturer and a bearing manufacturer, five different modifications were carefully examined.

The results are plotted and the percentage reduction in bearing friction is shown on a vertical scale. Different motor oils and different process lubrication methods also have temperature advantages.

Keep in mind that process pump failures can be circumvented by staying within acceptable dimensions, material composition, manufacturing-specific and application-related parameters. Of course, operations, maintenance and project engineering work together. However, once the right mentality is developed, it is not difficult to adhere to sound norms. The difficulty lies in developing the way of thinking.
