Elements and Performance Criteria
- Determine mechanical seal requirements
- Dismantle mechanical seal installations
- Mechanical seal assembly is examined and appropriate dismantling techniques, tools and equipment are selected to suit work requirements.
- Mechanical seal assembly is dismantled using engineering techniques and safe workshop procedures appropriate to the work requirements.
- All component parts are examined for wear, including housing, shafts, primary sealing elements, secondary seals, seat assembly etc., to determine need for repair or replacement.
- Where applicable, serviceable items are repaired by appropriate means.
- Primary sealing elements and secondary seals are removed for replacement where required, using correct and appropriate engineering techniques and tools.
- Select replacement items
- Reassemble mechanical seal installations
- Mechanical seal components are fitted using correct and appropriate engineering techniques and tools, including seal head, secondary seals, seat assembly, shaft and housing.
- Mechanical seal assembly is tensioned and adjusted to manufacturers' specifications.
- Mechanical seal assembly is tested using appropriate methods for compliance with specifications and operational performance.
