A centrifugal pump is a mechanical device for moving a fluid from a lower to a higher location, or a lower to a higher-pressure area. This study focuses to investigate the fluid flow characteristic and the efficiency of centrifugal pumps. A Centrifugal pump is functioning to convert rotational energy, often from a motor to energy in a moving fluid. For the experimental data, the analysis of the fluid flow characteristics and efficiency of the centrifugal pump was conducted by using the simulation to observe its characteristics and efficiency in the centrifugal pump that cannot be observed by experimental. The simulation on CFD modelling is acceptable which has the difference between experimental and simulation below 20%. The efficiency of the simulation was 29% meanwhile the efficiency for the experimental was 45%. Then, the pressure and velocity for simulation at 7m3/h flowrate were 421Pa and 35.0m/s, respectively. However, the pressure and velocity for pump specification at 12m3/h were 1090Pa and 47.8m/s, respectively. Therefore, it can be concluded that the fluid flow characteristic which is pressure and velocity, and their efficiency can be identified.
