Trimmed Impellers Save Energy

摘要

Pumping systems account for 20% of energy consumption in German industry. In the face of rising electricity prices for commercial customers, saving energy holds great potential for improving the economic efficiency of industrial plants. One option to do so is the use of trimmed impellers: On standardised pumps, reducing the impeller diameter to match the duty point saves 10% of energy on average. Impeller trimming is a standard feature KSB offers to its customers. Based on each individual customer specification, KSB provides this option for every single pump ordered.
