Redução de custos em manutenção de bombas centrífugas: um estudo de caso em uma empresa sucroalcooleira.

Abstract

This paper presents a case study conducted in a company in the sugar and ethanol industry with the objective of reducing costs related to the maintenance of centrifugal pumps. To achieve this objective, several quality tools were applied, such as the Pareto chart, brainstorming, cause and effect diagram (Ishikawa) and the 5W2H methodology. These tools allowed a critical and detailed analysis to identify the main factors that contributed to the high maintenance costs. Based on the identification of the causes, an action plan was developed using the 5W2H method, with proposals to mitigate the problems detected. The measures included the reorganization of the layout of the maintenance area, improvements in the infrastructure, standardization of processes and training of employees. As a result of the application of these strategies, it was possible to estimate a 32% reduction in the total maintenance costs of centrifugal pumps, in addition to an increase in the operational efficiency of the maintenance team.
