design standard for centrifugal pumps

Hey guys

I am working on stress analysis for pumps ,Gorman Rupp type 06B3-B type… For that I need to find allowable nozzle end loads as per design code used on these pumps. I cannot seem to get through to the technical guys at Gorman Rupp or local agents. Is there anyone who knows or who can point me in the right direction?

...and there is only one pump/nozzle manufacturer in the world?

Give Google a crack at it. I am positive you will find about a zillion charts and nomograms to read off just what you need.
