Practical Pump and Valve Technology


Power plants and other petrochemical industries deal with different types of pumps and valves. Understanding the operation & characteristics of pumps and valves will have an important reflection on the process quality, equipment and plant reliability, and the economics of the whole activity. Identifying the problems associated with pumps and valves are essential for diagnosis and troubleshooting and the needed maintenance for the particular type of pumps and valves.

This training course will introduce the participants to modern methods for the design, selection, operation, maintenance and troubleshooting of pumps, valves and the related components together with inspection tools. The course will focus on pump and valve characteristics, classifications and state-of-the-art technology. Early detection of failures through presenting actual case studies will be provided during this course.

Learning Objectives

Upon the successful completion of this course, participants will be able to:

  • Operate, control, maintain and troubleshoot pumps and valves in a professional manner
  • Identify the various types of pumps and valves and differentiate their features and functions
  • Review and improve the operating procedures and conditions of pumps and valves as well as the control loops
  • Apply safe start-up and shutdown operation of pumps and valves and interpret data analysis and calculations
  • Illustrate the different troubleshooting measures carried out in the operation of pumps and valves
  • Employ all safety considerations and other safety measures to be followed 
Target Audience

This training course is intended for process engineers, production engineers, petroleum engineers, maintenance engineers, instrumentation engineers, plant supervisors, plant technicians, shift controllers and other technical staff interested in pump and valve operation, control, maintenance and troubleshooting.

Training Methodology

This highly interactive training course will be presented using lectures, workshops and work presentations, case studies and practical exercises, videos and general discussion.
