Someone is offering me a couple of units such as this:

That would be for parting out.

I am wondering what is inside of those? Pumps? Counters? Anything else?

Usually a pump with dual heads (2 pumps if it also has a diesel nozzle)
Metering unit which controls how much low grade to mix with the high grade for
the blends. Set of flow meters Display, selection, control boards, receipt printer and
the credit card reader head.



That's great to know! Thanks! Those pumps, are they diaphragm pumps or
something else?

There are no pumps in those units, modern gas stations use submersible
turbine pumps similar to well pumps. All that is in those dispenser
units is a set of metering units, possibly some filters and a PC with
card and prox readers. I'm afraid scrap wise the stainless steel cabinet
it's all in is probably the most valuable part.

Take a look at this thread for more info than you ever wanted on fuel
stations:

Not to sure about that, around here you can hear the pumps pumping.
But even if modern pumps use STP's, if those are older pumps they
will have the pump inside them.

I think they would have to be quite old to actually have pumps in them.
What you hear is more likely to be either the noises from the metering
units, or in some cases if the area is quiet you may hear the in-tank
pumps whirr transmitted through the fuel lines much the same way as you
can hear your well pump 200' down the well if you listen at the plumbing
in the house.
