Energy Optimization Strategies for Industrial Pumps

This technical article discusses energy optimization strategies for industrial pumps, which are responsible for over 20% of global electrical energy use. It outlines the significant energy savings potential that can be achieved through improved pump efficiency. The article highlights that many operators overlook the efficiency of pumps, focusing instead on larger equipment. A study using Sulzer's machine learning technology revealed that 68% of pumps operate outside their preferred efficiency range, leading to substantial energy waste. The article presents the Energy Optimization Service pioneered by Sulzer, which addresses efficiency losses due to wear and operational changes. It emphasizes the importance of a comprehensive strategy that includes digital insights and continuous monitoring. A case study of a desalination plant illustrates the potential for annual savings of €1 million and a reduction of 2,345 tonnes of CO2 emissions through improved pump efficiency. The article concludes by stressing the vast untapped potential for energy savings in industrial pumps.
