Emphasis of this chapter is placed on the cavitation phenomenon arising in a condensate pump. The condensate pump is unique since the amount of gas in the inflow cannot be neglected. It is the responsibility of optimal design to relieve the cavitation effect. Research tools are to be used to validate the innovation. For the pump considered, the impeller meridional profile is modified to improve the cavitation performance. Furthermore, shortened blades are employed to minimize the disturbance of cavitation on blade pressure distribution. Proposed impeller schemes are examined using experimental and numerical methods. Experiments enable the evaluation of pump head and critical net positive suction head. Cavitating flows in the pump are virtually visualized using the CFD technique. The relationship between flows and pump performance is anticipated to be established based on the obtained results.
