PUMP SYSTEMS

Conclusion In this introduction we grouped the elements found in every pumped system and the purpose of these elements. We also saw how the energy

supplied to the system by the pump is used by the process elements and control elements to make a product and improve its quality. In future articles we will look at typical problems associated with real life piping

systems, develop troubleshooting skills to identify the problem and determine the possible solutions. In the next issue of Pump Industry we will look at a system that is unable to meet an increased flow requirement and what can be done to correct the system. In my experience, the best way to demonstrate a point is with examples. I like to provide real life examples to build troubleshooting skills in my columns. I have accumulated a variety of examples of pumped systems experiencing problems, but one thing I have learned is that I haven’t seen them all. That’s where you come in. If you have or are experiencing a problem within a pumped system, let me know and we’ll troubleshoot it together and then share the results with other readers.
