Up to 50% of the energy consumed by pump systems could be saved through equipment optimization and control system changes [1].

Industrial pumping systems that have been in operation for a long time may have experienced changes to pumping requirements over their lifetime, as systems move away from their design conditions.

Pump system designs are often difficult to optimize at initial installation. In addition, system design is sometimes focused on minimizing capital costs. As a result, energy and maintenance costs may not be fully considered.

Pumping system efficiency improvements may improve the life cycle costs periods from several weeks to a few years.

Energy consumption is a hotly debated topic across the globe, and given the European Union’s plans to dramatically reduce its emissions, energy audits will become a fundamental regulatory tool. By taking into consideration the present trend regarding the price increase of energy up to 2020 the estimated price increase will be cca. 20%, this requires significant attention from the energy management point of view.
