A Performance Study and Comparative Analysis of Head and Capacity in Single and Series Centrifugal Pumps

Abstract

Centrifugal pumps are commonly used to convert kinetic energy from impeller rotation into dynamic energy. This study examines the performance of single and series centrifugal pumps by measuring the head and capacity across various conditions. The findings show that the head and pressure in the series pump configuration are nearly double that of the single pump. This increase is attributed to the pressure buildup from the first pump, though the output head and pressure do not exactly double due to primary loss factors from longer piping. The capacity, however, remains consistent with that of a single pump. This paper provides an analysis of the hydraulic performance and efficiency of centrifugal pumps in both configurations.
