Abstract—The addition of a centrifugal pump to an automatic motorcycle is the main mechanism for a fire fighting motorcycle. However, the amount of water pressure that can be sprayed by a centrifugal pump can also be affected by the nozzle attached to the end of the hose. The purpose of this research is to find out the proper nozzle model so that the performance of the motorbike developed can work optimally. By using the experimental method, the basic nozzle model to be developed is a standard nozzle which is commonly used for fire trucks. The results of the development of 10 model variations are divided into two major groups, namely nozzles that use a ball valve between the cylindrical barrel and nozzle tip and the other large groups without using a ball valve, while in each model in the two groups it is distinguished by the length of the cylindrical barrel used. The fluid pressure simulation is collected using flow simulation software, and the model chosen is having the greatest pressure at the nozzle tip. From the simulation results, the work piece is made according to the predetermined size and tested on a developed fire engine motorbike and the actual pressure is measured using the Pitot tube which is placed on the nozzle tip. The nozzle which has the shortest cylindrical barrel length has the largest fluid pressure measurement both in the simulation and actual measurement, while the fluid pressure value from the simulation results has a higher pressure value compared to the actual one.
