Practical Pump & Valve Technology

Course Introduction

This intensive course will introduce participants 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.

The knowledge gained in this training will:

• Enable the delegate to optimise the operation and maintenance of different types of pumps
• Give the delegate confidence to carry out failure analyses on pumps thereby avoiding repetitive failures
• Allow tighter control of maintenance budgets by the avoidance of unplanned equipment failures in service.

Objectives

By the end of the training, participants will be able to:

• 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
• Critically analyse the methodologies employed within the organisation and instigate improvements where required
• Gained a required level of technical knowledge and skill to achieve that personal satisfaction
