A 3D model of all stationary components of the ATD HPOTP is analyzed using a superelement solution technique to obtain a better understanding of the pump behavior and to support pump testing. Emphasis is place on the methods used for determining deflections. As part of the model verification, analyses were conducted on the main housing model under proof-pressure and push-test loading conditions. The analysis at 109 percent rate power level resulted in asymmetric deformation patterns which were used to calculate operating and rub clearances. The present analysis is considered to provide the most realistic representation of the ATD HPOTP to date.
