Hello All

I am searching for information concerning qualifing nozzles on a set of diaphragm pumps. They are a set of Drum Condensate Pumps, low temp. The vendor has not provided allowables. I can not seem to locate any information in API 610, or B31.3, and all of COADE forums regarding diaphragm pumps. I am beginning to question if there is set way to qualify these pumps. I understand a dynamic analysis is going to be in order for the piping involved. Can some one shed a little light on the subject, or point me in the right direction.

Regards
KEV
