Açıklama	In this paper, the Smoothed Particle Hydrodynamics (SPH) method with dynamic boundary condition has been used to simulate 3D Fluid flow in the centrifugal pump. Severe fluctuations in the field of pressure and velocity is one of the major problems in this method. In this paper, the fluctuations have been corrected using Delta and Shift algorithms. The simulation was numerically performed with real fluid viscosity (laminar and turbulence). Validation of this method indicated that in the case of real fluid viscosity, the Delta and Shift algorithms should be used simultaneously to obtain good agreement with the experimental data. To validate the pump results, a comparison was made between the numerical outputs and the performance curves of pump EN 125-315 of Pumpiran Company under relatively similar conditions. The results of this comparison showed that the error of simulation of pump head, consumption power and efficiency values compared with experimental data were about 12, 5.5 and 16 percent, respectively.
