How can we predict the actual test performance of pump from CFD. I need some formulation/calculation method to predict closure.

There are lots of tools developed for just this. Typically our approach for compressors is to start with a meanline or 1D code first. Basically it's a glorified "velocity-triangle" approach to solving, but will get you very close.
From there a model is created and meshed. For the best mesh quality, we bring it into ANSYS ICEM in order to get a full hex mesh. Mesh quality if very important with CFD; always.
At that point it's brought into your solver and solved. Moving boundaries can be applied to the rotor and from what I've seen, results can be quite close to experimental values.
