Proper lubrication in a process pump is critical to components’ function and longevity. The key points for obtaining proper lubrication are understanding lubrication fundamentals and equipment/application details. The primary functions of the lubricating system in rotating equipment are:

• Minimize or eliminate friction – separate moving parts
• Wear control – reduce abrasive wear
• Corrosion control – protect surfaces from corrosive substances
• Temperature control – absorb and transfer heat
• Contamination control – prevent dirt and wear debris damage

This paper covers some basic lubrication fundamentals and types of lubricants as well as different methods currently used for providing lubrication to the bearing. This paper also introduces the importance of maintaining the critical elements of lubrication, quality, and quantity, and different means of accomplishing them.

What’s New:

• Updated definitions of oil film conditions on how viscosity impacts the film that forms
• Expanded explanation of the effects of particle and water contamination on bearing life in pumping applications
• New commentary on the three distinct phases of water that can exist in oil, and the visual condition of the oil during these phases
• Added section on addressing humidity control in pumping applications through the use of desiccant breathers
