No matter what type of a "surface pump" the best that can be done is
to create a vacuum so that atmospheric pressure will force water to
the surface from below. 33 feet or so from memory, although if you
want the exact value of suction you could look up the range of
atmospheric pressures in your locality.

Ah. Then all those windmills were pumping shallow
surface water then?

Not necisarily, If I understand some of them ran a sucker rod down to
the pump wich was mounted down the shaft, so no real problem with a
deep well so long as you put ypur pump down there too.
