Mechanical (Liquid) Seals: General (Installation, Operation, Troubleshooting, and Retrofitting)
Discussion GroupMechanical seals are the most common method of sealing industrial centrifugal pumps and other rotary equipment. Although the
basic concepts of a seals are simple, successfully using seals requires an understanding of the selection and operational
requirements which can be unique for a specific application. In this discussion group, we will cover many of these considerations
along with other application experiences from end users and seal OEMs. The discussion group will actively solicit topics from
the attendees so the discussions will address real-world problems and challenges faced by the group.
