MODULE DETAILS

Module 12: Pumps and Compressors

 

Nominal duration: 6 weeks (72 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

 

 

This module focuses on the fundamentals. Students have an opportunity to discuss pump/compressor construction, design applications, operations, maintenance and management issues and be provided with the most up-to-date information and best practice in dealing with the subject. They will develop the skills and ability to recognize and solve simple pump/compressor problems in a structured and confident manner.
