MODULE DETAILS

Module 8: Pumps and Seals

Nominal duration: 3 weeks (24 hours total time commitment)

This time commitment includes the preparation reading, attendance at each webinar (1 hour plus 15-30 minutes for discussion), and the time necessary to complete the assignments and further study.

MODULE PURPOSE

To provide the participants with the requisite knowledge to identify various pump and seal types, assess their performance and efficiency parameters, understand sealing principles, and implement correct lubrication practices

PRE-REQUISITE MODULE(S)

Module 7: Fluid Power Systems and Components

ASSESSMENT STRATEGY / CONDITIONS OF ASSESSMENT

To evaluate the achievement of the learning outcomes; written assignments, group projects and practical exercises are set. The Training and Assessment Matrix (TAM) documents the assessment criteria included in these assessments, based on the learning outcomes. The Training and Assessment Strategy (TAS) documents the overall training strategy for this Advanced Diploma course. The conditions of assessment are outlined in the Assessment Guidelines, TAM and TAS. Written assignments, group projects and practical exercises are required to meet assessment criteria outlined in the Assessment Guidelines, TAM and TAS.
