RE: protect Vetrical Pump - on Earthquake

I believe that there are FEA analyses of this type of pump that was done for Nuclear Power Plant Equipment qualification.

This would be a good place to start.....

What information are you going to use to define your earthquake.. ?
Do you have building response spectra ?

This might help: http://turbolab.tamu.edu/proc/pumpproc/P20/06.pdf

RE: protect Vetrical Pump - on Earthquake

As mjcronin already posted, Talk to one of the major manufacturers that have seismically-qualified nuclear safety-related pump designs. That would be flowserve, Sulzer, goulds, Hayward Tyler in the US. You're probably looking at seismic supports/rings near the bottom of the can.
