Abstract
Nowadays, most research on pump design are focused on the efficiency of pump and solving its problems, but a few of researchers focus on the fire pump machine, whatever if hydraulic or design view, because in the fire pump engine, the efficiency isn't that much important, where in fire pump the important parameters are flow rate and the head of the pump regardless its efficiency. Nevertheless, the fire pump needs high capacity for operation process to provide the required flow rate at the required head so that the pump performance can be enhanced. One of the influencing phenomena is the cavitation inside the pump structure, especially at high operating speed where there is a huge vacuum created for sucking water and pumped later. In this study, the pump characteristic of a firefighting pump was calculated by an experiment and by a numerical simulation too. In addition, cavitation presence was investigated in order to compare it with the experiment results too.
