OK.  But just remember its comparing apples to oranges and you usually get what you pay for... or don't.

For lo press, lo temp, non-critical services, non-hazardous substances, lo stress conditons, I don't see anything wrong with using ANSI pumps.  For critical services, I wouldn't touch one with a 1/2 joint of pipe.  With APIs, you know what you're going to get before you open the box.

See your company spec.  As you note, some project or company specs simply require API for any and all hydrocarbon service.

I have been involved in two truck loading rack projects in the past two years.  On one, located at a marine terminal, ANSI pumps were used, worked well, delivery was great, customer pleased.  On the other, which happend to be located on the refinery property, API pumps were used, cost a whole lot more, delivery was longer, pumps work great.

In my opinion, if you can go with ANSI pumps, do so.  There is no compelling reason to go with API on such a simple application.  Magnetic pumps
