Comparative analysis of the mechanical behavior of three volute forms of centrifugal pump

This paper presents a comparative based analysis on the mechanical behavior of three different forms volute centrifugal pump with spline, radial and tangential type using ABAQUS Software calculation code. The result shows that stress concentration is localized at nozzle for all types forms. founding an interesting element as regards to possibilities adaptation particular operation. Also it found least stressed compared other two displacements are more pronounced in case volute. These data can be exploited order predict possibility accidental rupture this element. From another point view have indirect influence appearance vibration, noise fluctuations pressures speeds due interaction between fixed part (volute) mobile (impeller).
