Interesting. Just took a look at that pump and it is much lower volume than the one I linked. 0.67gpm at 40psi. The one I linked is 3gpm at 60psi.
Regardless, I'd rather use a submersible 110V pump than that one anyway, I'm just wary because none of them are rated up to the high pressure required by the spray balls. Pretty much why I started this thread.
