Design And Application Of Dual Gas Seals For Small Bore Seal Chambers
MetadataShow full item record
Since the release of dual gas lubricated seal technology for process pumps over three years ago, this technology has provided a more versatile, efficient, safe, and less costly alternative to sealless pumps and traditional dual seals, primarily I the process pump market. In the past, to utilize this gas seal technology, the pump had to be fitted with an enlarged seal chamber, thus limiting its use on existing equipment and applications. Dual gas seal technology is now available for small bore seal chambers, allowing existing equipment to be retrofitted without any modification to the pump. Discussed herein is the design, the analytical tools used in the development along with the features and benefits of the seal. Also discussed are several applications utilizing dual gas seals on small bore process pumps.
