API Pump Specs

[Canoman]

Anyone know of a website that lists API Pump specs such as A-8, S-1, S-6, etc. and what each of them means?

I know that one of these designations basically specifies all materials in a pump, but I do not know what each spec means. When we do equipment lists, we show things like "Carbon Steel Case, Stainless Steel Internals", but when all I get is something like "S-1", I don't know what that means.

Thanks
