Description
This unit covers dismantling, selecting, reassembling and installing mechanical seals.
Notes
Elements and Performance Criteria
1. Determine mechanical seal requirements
- 1.1. Principles of mechanical seals are understood and applied.
- 1.2. Operational function of mechanical seal components is understood.
- 1.3. For new mechanical seal installation, specifications are interpreted from engineering drawings etc.
2. Dismantle mechanical seal installations
- 2.1. Mechanical seal assembly is examined and appropriate dismantling techniques, tools and equipment are selected to suit work requirements.
- 2.2. Mechanical seal assembly is dismantled using engineering techniques and safe workshop procedures appropriate to the work requirements.
- 2.3. 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.
- 2.4. Where applicable, serviceable items are repaired by appropriate means.
- 2.5. Primary sealing elements and secondary seals are removed for replacement where required, using correct and appropriate engineering techniques and tools.
3. Select replacement items
- 3.1. Replacement items are selected using manufacturers' catalogues, spare parts lists, engineering specifications or sample, using standard operating procedures.
4. Reassemble mechanical seal installations
- 4.1. Mechanical seal components are fitted using correct and appropriate engineering techniques and tools, including seal head, secondary seals, seat assembly, shaft and housing.
- 4.2. Mechanical seal assembly is tensioned and adjusted to manufacturers' specifications.
- 4.3. Mechanical seal assembly is tested using appropriate methods for compliance with specifications and operational performance.
RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Seals
Range of mechanical seals may include carbon, satellite, neoprene and other associated materials
Mechanical seal assembly
Range of mechanical seal assemblies used across different sealing applications

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
A person who demonstrates competency in this unit must be able to dismantle, select, reassemble and install mechanical seals. Competency in this unit cannot be claimed until all prerequisites have been satisfied.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.
Context of and specific resources for assessment
This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.
This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with dismantling, selecting, reassembling and installing of mechanical seals, or other units requiring the exercise of the skills and knowledge covered by this unit.
Method of assessment
Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning should not require language, literacy and numeracy skills beyond those required in this unit. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.
