protect Vetrical Pump - on Earthquake

[jsn1980]

dear all

Vertical can Type Pump (Can Dia.355mm & 2521mm Length)at very high seismic zone & Earthquake.

To protect this vertical pump from High Seismic zone & Earthquake.

we are planning to do below method's
(1) Appropriate support position by FEM analysic
(or)
(2) Metallic Expansion Bellow on suction & discharge Nozzle.


Please give your experience idea and solution. Which one is good? how to solve this issue.

Regards

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:

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.
