Nissmurano,
No, self priming is not covered by ANSI B73.1 or similar standard.
Eventhougt Flowserve and Goulds has ANSI self priming pump, that has similar features, and interchageable parts with true ANSI B73.1, there are not a full compliance ANSI B73.1
The problem is mainly, the suction or the discharge nozzle that because of casing desing can not meet dimmensional requirements for ANSI B73.1.
But why do you looking for true ANSI self priming pump?
I hope this helps.
