Basic repairs are typically done to address minor issues, such as scratches or nicks in the seal faces, without the need for extensive disassembly. These repairs are generally quick and relatively inexpensive and are designed to improve the performance of the seal.
Major repairs involve a more extensive process, such as disassembling the seal and replacing damaged components. This type of repair is typically necessary when the seal has suffered significant damage or wear and tear.
Refurbishment involves taking a used mechanical seal and restoring it to like-new condition. This process can involve a range of repairs and upgrades, including replacing worn or damaged components, re-polishing the seal faces, and upgrading the seal materials to improve performance.
Conversion involves taking an existing mechanical seal and modifying it to meet the requirements of a different application. This process may involve changes to the seal materials, seal face configuration, or other components to ensure that the seal can operate reliably in the new application.
