Thanks danb and shr for these explanations.

But, according to EJMA these loads acting on pump nozzle is less than acting on pump anchor. So, how can I simulate in CAESAR II the load that goes only to nozzle (for API 610, is this important load?).

If we model a pump nozzle as a restraint ANC, the load resultant is thrust load, and if we use this force to compare with API 610 allowables, we will commit a mistake due API 610 verify only loads on the nozzle.

danb, but if the load acting in pump casing is bigger than nozzle, this load will be response for shaft misalignment, am I right?

So, I have 2 options:

1) I do hand calculations as shown in EJMA for pump nozzle loads and use analysis module of CAESAR with these loads.

2) Simulate only the load on pump nozzle (desconsidering as ANC)

What I need to do?
