Résumé

System Optimization

Variable speed drives in pump systems are now a mature technology, which can generate large benefits to the user in cost savings and reliability improvements, in the correct applications. However it is apparent that opportunities for achieving lower life cycle costs are being missed by the continuing use of traditional control methods. Conversely there are examples of ineffective systems and wasted expenditure, caused by the incorrect application of variable speed drives.

Europump/HI's Variable Speed Pumping: A Guide to Successful Applications describes the basic principles of pump, motor and drive technology through to more advanced detailed concepts. The guide encourages the use of variable speed pumping, in appropriate applications, leading to cost savings from both reduced energy consumption and increased pump system reliability.
