Submersible pump impeller

The submersible pumps are used highly at the domestic and commercial level, so to increase the efficiency study of detail flow field in pump is necessary nowadays. With this regard an experimental was conducted on the mixed flow pump in pump manufacturing company. The head achieved by experimental result was 8.08 m. By using design parameter of existing impeller as used in experiment the geometry and cavity model of impeller was modeled in pro–e. After that CFX mesh, inlet, outlet boundary conditions, hub, shroud and blade profile defined in turbo mode for CFD analysis in ANSYS 12.1. Results from the CFD code showed good agreement with experimental result and it was 7.45 m. So, the efficiency of pump calculated by experimental result was 53.27 % and by CFD analysis 49.6 %.
