Somehow it just doesn't seem as though lifting water that distance
should be so difficult (unless you are talking bucket on a rope). For
$40.00 you can buy a simple centrifugal pump that is rated at a 23ft
lift. http://makeashorterlink.com/?M2DC126FB

A pump that pumps to a 23 foot head probably isn't going to move much water at 20 feet.

You have to read the whole rating. A pump is rated at "X" GPM at a
given head. This pump ad says the max suction lift is 23' It will pump
UP against the head a lot higher I imagine. They don't have the
GPM/head curve in this ad.

The ad says max lift with no mention of suction. The pump will pump a little water 23 feet up, and not much more. It is
obviously a sump pump. Sump pumps don't generally generate much pressure.
