This 20H masterclass is designed to provide you with a complete understanding of construction details and functioning of :

  1. Pumps

  2. Centrifugal compressors

  3. Reciprocating compressors

This understanding is a prerequisite for a successful and flawless operation of your plant and piping system.

This 20H masterclass includes extensive graphics, 3D animations and cross-sectional views to give you a virtual practical exposure on rotating equipment.

The objective of this masterclass is threefold :

1. Break down for you all the pumps, centrifugal compressor and reciprocating compressors operating principles into easily digestible concepts like :

  • Cavitation

  • Performance curves

  • Fluid Head

  • Net Positive Suction Head, NPSH

  • System resistance

  • Surge and Stonewall

  • Capacity control

  • Pulsation control

  • Lubrication

  • Cooling

  • ...

2. Illustrate through 3D animations and cross-sectional views the main rotating equipment mechanical components, state their function and operating limits, like :

  • Impellers

  • Bearings

  • Mechanical seals

  • Packing

  • Crossheads

  • Pistons

  • Compressor valves

  • ...

3. Provide guidelines and best practices for operation, maintenance and troubleshooting of rotating equipment in accordance with the latest API Standards


Also included in this masterclass 2 valuable Excel Workbook

  1. Centrifugal Compressor Performance Excel Workbook

  2. Pump Calculations Excel Workbook

These workbooks provide qualitative and quick comparisons and application notes for centrifugal compressors and pumps. They describe calculations and procedures to predict performance characteristics, especially head, discharge pressure and power.


So with no further ado, check out the free preview videos and the curriculum of the course and we look forward to seeing you in the first section.

Hope to see you there
