Abstract (2. Language): 
In this paper a multistage electro pump including a 4 staged stainless steel centrifugal pump, a 4 kW three phase induction motor and two control strategies including constant speed and variable speed methods, is modeled and results are compared with experimental data and Affinity results. The multistage centrifugal pump provides 16 m 3 /hr flow rate and 58 mwater head at BEP (Best Efficiency Point). The model is dynamic and any variation in flow rate results in corresponding variations of electro pump operational parameters. At constant speed mode, the electro pump works at nominal speed immediately after start, regardless to the system characteristics. But, PID speed controller adjusts the rotational speed of the electro pump to the optimized speed regarding to matching the pump working point with the consumption point to save the energy. The model is simulated utilizing MATLAB SIMULINK software with ode45 solver and variable step size.
