Evaluating The Long-Term Performance Of Composite Wear Rings In Centrifugal Pumps
MetadataShow full item record
Refinery instituted a standardization program to install composite wear rings with reduced clearance into a large population of pumps. Purpose of study was to improve pump reliability. Study was conducted on first 61 pumps upgraded. Criteria was pump services < 500 F, refined product, chemical, or utility service (no bottoms or slurries). Details of installation, operating conditions, and preliminary results were published at 2007 International Pump Users Symposium. This Case Study provides long-term results after more than 4 years of running time.
