"In case of Non-Lethal Service the pump could be modelled with K=1,000,000 Lb/in and Kr=1,000,000 Lb-in/deg. And ensure that Dx,Dy,Dz,Rx,Ry & Rz are within 0.005 in. or degrees."

Can the above Statement be considered Valid for Analysis in Caesar while considering the Pump nozzle as Flexible Anchor.

Hello!

From where do you have these values for nozzle flexibility? I think this flexibility depend on the pump dimensions. I usual make the stress analyze with pump nozzle modeled as anchor, or imposed displacement node (if I have data for it). I model the pump nozzle as flexible anchor only when I have data for it from the pump provider.
In the most cases the stress analyze with the pump nozzle modeled as an anchor is conservative.
