Scope of Energy Conservation in Pumping System

Abstract

Pumps consume about 22% of the world’s total energy generated, out of which 16% is consumed by centrifugal pumps and 6% by rotodynamic pumps. According to the American Hydraulics Institute, 30% of the total electrical energy consumed by pumping systems can be conserved either by designing highly efficient systems or by using appropriate pumps. As a result, the primary focus of global energy policy makers is to enhance energy efficiency in pumping systems. This paper aims to highlight the areas that need to be address in order to increase the pumping system efficiency. It is evident from studies that about 30% to 50% of the energy consumed by pumping systems could be saved through piping system components or control changes.
