Analysis And Testing Of Alternative Bearings Materials For Applications In Sealless Pumps
MetadataShow full item record
As the usage of sealless pumps increases, so do the demands for journal bearing materials that can operate successfully through the thermal upsets that can take place in these pumps. Material specification literature is only a start at making a knowledgeable choice. A test facility and procedure was developed to evaluate different journal bearings materials for use in sealless pumps. The facility simulates an actual American Petroleum Institute (APO) sealless pump bearing installation. Fifteen different materials combinations were tested. Tabulated and graphed test results are presented. A 30 percent carbon fiber polyetheretherketone (PEEK) and a 15 percent graphite filled polyimide material operated 40 minutes in a no flush water condition. Silicon carbide and most of the carbon graphite based materials had no wear after the no flush water tests were terminated. Polymer based materials had the most wear and operated the shortest amount of time in the no flush water condition.
