Barrier And Buffer Fluid Selection And Considerations For Mechanical Seals
MetadataShow full item record
The increased use of pressurized and non-pressurized dual mechanical seals has driven more installations to require the use of barrier and buffer fluids. While some end users have viewed the selection of barrier fluids as an afterthought, their selection is a critical aspect of the seal operation and reliability. A thorough application review requires an understanding of the mechanical seal, sealing system, pump, and process. Fortunately there is a large installed base of successful installations to guide barrier and buffer fluid selections. Through the careful selection of fluids and good operating practices, barrier and buffer fluids can help provide reliable dual seal operation.
