Oil and Gas Engineering Training Courses

Practical Pump & Valve Technology


This course will introduce delegates to the different types of pumps and valves and their associated terminology. Centrifugal and positive-displacement pumps, packing, mechanical seals and sealing systems, bearings, and couplings will all be discussed. Valves for isolation and valves for control will be addressed.

The application of the different types of pumps and valves will be discussed along with their suitability for different operational duties. Operation, troubleshooting, and maintenance will be dealt with in-depth

Targeted Groups:

  • Supervisors
  • Team Leaders
  • Technicians
  • Anyone who wishes to update themselves on pump and valve technology, judge the suitability of different types of pumps and valves for their needs, and learn how to operate and maintain them for the benefit of their organizations

Course Objectives:

At the end of this course the participants will be able to:

  • Understand the different types of pumps and their associated terminology
  • Understand the Centrifugal and positive displacement pumps, packing, mechanical seals and sealing systems, bearings and couplings
  • Understand the different parameters affecting the operation of valves
  • Select the right valve for the particular application and to perform the necessary calculation for valve sizing
  • Perform troubleshooting of systems involving valves
  • Decide on the right maintenance plan concerning different types of valves

Targeted Competencies:
