Key Performance Indicators for Pumping Systems
It is very useful to be able to track the performance of a system in order to see how efficiently it is operating relative to optimum, but also to be able to easily and quickly discover deviations from normal. When monitoring systems it is therefore desirable to be able to measure some parameters that give an indication of how the system is performing and if performance changes over time. Pump systems in industry are often connected to various types of monitoring and control systems. Traditionally flow rate, pressure, power or current are monitored. Just monitoring one or several of these entities is, however, not enough to get a good picture of the system performance. However, in many cases the information collected can be made more useful if different parameters are combined to form key performance indicators which are followed in time. Monitoring of pumps can for example be made more useful by dividing the flow and power to form specific energy, than just measuring them independently. It is suggested that specific energy would be a very useful key performance indicator to follow and monitor for pump systems. It is also shown how US Department of Energys PSAT program can be used together with the specific energy concept to construct a diagram that shows total system performance relative to an optimal system. This diagram makes it easy to demonstrate the optimization potential both as a function of improving the existing system components and as a function of eliminating throttling losses. The diagram also shows how the cost of pumping is affected by such changes to the system.
