Practical Pump & Valve Technology

What are the Goals?

At the end of this training course, participants will:

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

Who is this Training Course for?

This training course is directed towards:

• Supervisors
• Team Leaders
• Technicians

This Practical Pump & Valve Technology training course will also benefit 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 organisations.
