    In this technical project a single-impeller ram pump is designed using Krol's mathematical model, each of the parts are modeled according to the calculations previously made. It is based on the available flow of the community of Chilcapamba, taking into account the unevenness of the terrain, the most optimal design is sought. In the design of the pump, maximum pressure values of approximately 0.3 MPa, dynamic pressure of 8.2 Kpa and speed in the impulsion valve of 2.87 m/s were found. The modeling is done in a CAD program, where each of the parts is detailed, especially the discharge valve, after this the simulation of the pump operation is performed in order to corroborate the data calculated analytically, the simulation is carried out with boundary conditions according to your requirement, where the mesh metric had a value of very good with this ensuring valid results and very close to reality. As for results, the most important parameters were simulated where the results of velocity in the valve, dynamic pressure in the valve and maximum pressure in the body of the ram were obtained obtaining values of 0.382 m/s, 8107 Pa and 380453 Pa respectively, also reflects a result where the areas of greater turbulence is observed. These values were compared with those mentioned above by means of a relative error study where values from 0.01 to 0.29 were found. With this it could be observed that 3 of the 4 analyzed values comply with the requirement of having a percentage lower than 0.16 to be validated, while one of them is out of phase, but not considerably
