| dc.description.abstract | Anti-friction bearings in process pumps, by design frequently utilize oil sump lubrication technology. For many years, it was an accepted condition that the lubricating oil used in oil sump bearing lubrication needed to be changed on a regular basis to prevent high levels of contamination that can lead to premature bearing failure, contributing to equipment downtime. Often, the indicators used to determine change intervals were based on visual elements of oil, such as color. As simple as this method is there are many critical elements that will degrade the overall performance of the lubricant, resulting in premature component failure. Understanding how these elements work together to provide reliable lubrication and, more importantly, increased equipment life and performance are explained. Contained in this document is the compilation of pump manufacturer and component producer design specifications, end user focus group input, new tribology data, laboratory tests, case history studies, and best practice recommendations. | en |
