Abstract

Pump is an important machine to transfer the fluid from one place to another. The experiment on the centrifugal pump (Gilkes Pump) on the laboratory based is presented in this paper. The objective of this paper is to analyze the characteristic of the pump in order to provide the information about how to operate the pump on the optimum conditions. Two different speeds include 1500 and 1700rpm at various head (1-8m) and flow rate were applied. From this experiment the performance of the pump was evaluated. The results show that the higher pump efficiency was obtained at 5.5m head with flow rate of 0.10m³.min^-1 and 5.4m head with flow rate of 0.15m³.min^-1 operated at two different speeds with the efficiency was 84 and 96.81% respectively. The statistical data show that there is a significant relationship between parameters observed in this experiment.
