Aspectos Importantes na Utilização de Bombas Centrífugas em Velocidade Variável para a Redução do Consumo de Energia

Abstract

The study examines the use of variable speed centrifugal pumps as a solution to reduce energy consumption in water supply systems. It covers theoretical principles, technological aspects, and economic feasibility, employing frequency inverters to adjust flow according to demand. Two case studies illustrate the method's effectiveness: parallel pump operation and tank level control. Results show significant energy savings with short financial payback, emphasizing the need for technical and economic analysis for implementation.
