Those systems place the pump down in the well within 22' of the water.
You obviously are not aware of the physics or mechanics involved with
pumping water. The atmosphere will only support a column of water about
29' high. It's exactly the same as a mercury barometer. The atmosphere
will support a column of mercury about 30" high and no more.
It's you that hasn't a clue.

Okay, I've been following this thread, admittedly not knowing (or rather,
not remembering from school) the maximum height a column of water could be
without assistance.

That being said, I distinctly remember the old-style hand pumps... the
kind you find in state camping grounds, and used to find in highway
waysides, and people who had them on wells with a water table WELL below
22 feet.

So, I did a little checking, and came up with this table:
http://www.aermotorwindmills.com/handpumps.htm (there's a nice table about
halfway down the page).

Am I wrong in thinking this is a standard hand pump, or is this NOT what
you and Tom are talking about?

I'm not talking about different pumps. The pumps are all the same. The pump
you linked to is placed down in the well-close to, or in the water.
The 22' is not dependent on manufacture or design, it is the maximum height
of a column of water that atmospheric pressure will support. I didn't come
up with that figure; some scientist 400 years ago did. Please catch yourself
up.
