This paper reveals the study of effect of various parameters on the performance of the external gear pump along with its flow characteristics. The two externally meshed spur gears plays a very important role in proper functioning of the gear pump as per its designed performance. Hence, it is very important to control the various parameters of the gear. The effect of variation of such parameters like pressure angle, module, number of teeth, correction factor, span, etc. on the output of the gear pump is analyzed. Also, the graphs for such parameters are plotted against discharge of the gear pump, which is referred as flow characteristics of the gear pump. The performance characteristics of the gear pump for various parameters are also studied for the case having unequal number of teeth on each gear. With the increase in parameters such as module, no. of teeth, face width, the discharge of the gear pump increases. While, the discharge increases with increase in pressure angle upto certain value and then it decreases. As the flow pulsation factor decreases, discharge increases. Excessive axial and radial clearance beyond certain limit causes leakage, which reduces the discharge.
