The first edition of API 682 was the first broad-based standard covering the design and application of mechanical seals in centrifugal and rotary pumps. One of the main goals of this standard was to capture successful field experiences in refineries and create a methodology that would guide the reader to a successful solution. Since its introduction, sealing technology has continued to advance. New designs such as gas seals and dry running containment seals have been developed. In addition, industries other than refining have recognized the advantages of the first edition. Many of these industries use pump designs that were not covered by the standard. The second edition task force has expanded the scope of the standard to include applications in more pumps, document new seal designs, and introduce new piping plans and testing requirements. API 682, Second Edition, has also been reformatted in preparation for its release as an ISO standard. These changes would be made while keeping the focus of improving reliability and meeting emissions requirements.
