Amsterdam, Netherlands
From Date: 07-Aug-2023   
To Date: 11-Aug-2023
5 days

Pumps and compressors find extensive use in petrochemical process plants, water circulation systems, A/C and heating systems, and many other applications.

Keeping these machines running with least troubles and shutdown decreases the downtime of the whole system. Right machine selection appropriate to the right application, right machine operation, effective maintenance programs, reliable monitoring system, and skilled personnel capable of doing the right trouble shooting are essential requirements for prolong machine life. All the above can be achieved via deeper understanding of the machines construction and tolerances, the limits and constrains on their operation, and the more effective controlling methods.


This course will offer the opportunity to learn more about pumps and compressors, their design, construction, operation, performance curves, control and troubleshooting and maintenance. During the course participant’s discussion, comments, bringing up their own problems are welcomed and encouraged. Short tests on the course material will be performed to examine the degree of delivering the right and quality of the presented material.    

  • Review the basics of Pumps and Compressors
  • Learn how the performance curves of Pumps and Compressors are measured and calculated
  • Use the similarity laws to calculate the Pumps/Compressors performance at different speed and rotor size
  • Learn methods of troubleshooting and maintaining Pumps/ Compressors

Highlight the importance of the related international codes and standards


Supervisors, Engineers & Facility/Utility engineers, Technicians, Operating Personnel or anyone require a working level knowledge of pumps & compressors.
