National University of the center of the Chair in PERU: Laboratory II Professor of by: eng. MARIO HUATUCO GONZALES student: ROJAS ZORRILLA, Jose. SEMESTER: VIII 2008 overview the hydraulic behavior of a certain model of pump is specified in their characteristic curves representing a relationship between the different flow values provided by the same with other parameters such as the manometric height, hydraulic performance, power consumption and the required NPSH. These curves, experimentally obtained on a test bench, are provided by the manufacturer to a certain rotation speed. It is curves drawn from statistical series and are, therefore, subject to certain tolerances.

One in which the yield is maximum constitutes the point of a pump design. The point of operation of a pump is going to be determined by the intersection of the characteristic curve of driving or network with load (curve caudal-altura gauge) of the pump curve. The characteristic curve is 100/200 pump mud which is located in the Termohidraulica of the Faculty of mechanical engineering laboratory, this curve was performed by the percentage method. INTRODUCTION this report show the experimentation that took place in the facilities of the laboratory by of the Faculty of engineering mechanics of the University national of the center of the Peru. The test consisted in analysing the operation of pump centrifugal 100/200 mud that has our laboratory, data were based on the simulation of the flow regulation, in order to obtain the characteristic curve of the pump by the percentage method. THEORETICAL framework the performance of a centrifugal pump is can demonstrate graphically through a characteristic curve that, normally, have data relating to the total geodetic height, to the effective power of the engine, to the efficiency, the NPSHR and to the positive level, information provided in relation to the capacity of the pump. Each pump centrifugal is characterized by its particular characteristic curve, which is the relationship between its flow and its lifting height.
