Head is the height that the water can be pumped to vertically. pump with 26feet of head can pump up to the exit point of hte tubing 26 feet above the height that hte pump is at... obvioulsy it can pump more than 26 feet if the tubing is at the same height relative to the pump. it could pump much much furter.. but stil there is a point when the resistance of the water in the tube will cuase the pump to stop flowing even if the tubing is horizontal. this is just because the water would be so heavy that the pump could not start moving it.
by absolute pressure do you mean the pressure at a given point???
not that this maters but water isnt compressable. if you take water that is 10 thousand feet below sea level (not that there are any places that deep i think) and bring it to sea level it wont get any "bigger". But this doesnt apply to water cooling.
