Course Description


The seminar will introduce delegates to the different types of pumps, motors and drives and their associated terminology. Centrifugal and positive-displacement pumps and compressors, packing, mechanical seals and sealing systems, bearings and couplings will all be discussed.

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

The highlights of this course are:

  • Compressors and compression systems
  • Pumps and pumping systems
  • Discussion of mechanical and dry gas seal design and associated issues
  • Predictive Maintenance techniques
  • Motors and Variable Speed Drives


At the end of this seminar, participants will have:

  • Have an understanding of the different types of pumps and compressors
  • Be able to operate pumps and compressors as close as possible to the design efficiency
  • Will be able to monitor pump and compressor efficiency, availability and reliability
  • Have learnt about selection, operation and maintenance strategies
  • Be able to troubleshoot pump and compressor problems
  • Be able to specify, operate and maintain fluid movers and drivers

Training Methodology

The 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.

Organisational Impact

Predictive maintenance of rotating plant is vital to the budgetary success of the operations organisation. On completion of this seminar, the delegate will be able to critically analyse the methodologies employed within the organisation and instigate improvements where required.

  • Enable development of a proactive maintenance regime within the organisation
  • Allow tighter control of maintenance budgets by the avoidance of unplanned equipment failures in service
  • Enable optimisation of the operation and maintenance of different types of pumps and compressors
  • Enable failure analyses on pumps and compressors thereby avoiding repetitive failures
  • Improve equipment reliability and availability
  • Improved communications between production and maintenance by better understanding of equipment design and operation

Personal Impact

Technical knowledge is key to effective control and peer respect within any maintenance organisation; when this is achieved personal satisfaction follows. This seminar will give the delegate the required level of technical knowledge and skill to achieve that personal satisfaction.

  • Understanding of pump and compressor operating and maintenance techniques
  • Ability to put in place measures to quantify equipment condition
  • Interface with pump and compressor equipment providers
  • Identify and specify new and replacement pumps and compressors
  • Ability to improve equipment reliability and availability
  • Be better able to interface with other departments by virtue of improved knowledge of the equipment


This seminar is directed towards:

  • Supervisors, Team Leaders and Professionals in Maintenance, Engineering and Production
  • It is suitable for Professionals who expect to become involved at any stage in project applications and applicable maintenance technologies

The seminar will also benefit those who wish to update themselves on pump and compressor technology, judge the suitability of different types of pumps and compressors for their needs, and learn how to operate and maintain them for the benefit of their organisations.
