Practical Pump & Valve Technology


This LAKESHORE ISL Practical Pump & Valve Technology training seminar 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.

The knowledge gained in this LAKESHORE ISL training seminar will:

  • Enable the delegate to optimize 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


At the end of this LAKESHORE ISL training seminar, 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

Training Methodology

This LAKESHORE ISL Practical Pump & Valve Technology training seminar will be conducted along workshop principles with formal lectures, case studies and interactive worked examples. Relevant case studies will be provided to illustrate the application of each tool in an operations environment. Each learning point will be re-enforced with practical exercises. There will be ample opportunities for discussion and sharing experiences.

Organizational Impact

On completion of this LAKESHORE ISL Practical Pump & Valve Technology training seminar, the delegate will be able to critically analyze the methodologies employed within the organization and instigate improvements where required.

Personal Impact

Technical knowledge is key to effective control and peer respect within any maintenance organisation, when this is achieved personal satisfaction follows. This LAKESHORE ISL Practical Pump & Valve Technology training seminar will give the delegate the required level of technical knowledge and skill to achieve that personal satisfaction.

Who Should Attend?

This LAKESHORE ISL training seminar is directed towards:

  • Supervisors
  • Team Leaders
  • Technicians

This LAKESHORE ISL Practical Pump & Valve Technology training seminar 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.
