You’re missing the fundamental difference in the power vs distance curve. In the case of sucking water, it flatlines and no amount of additional power can move the water another inch once you’ve exceeded the pulling power of a perfect vacuum.

Without looking up the actual equation, I would guess that this is never true (or at least practically never) when pushing water, because you’re not limited by atmospheric pressure.

When pushing you have to provide enough energy to move all the water in front of you, but if you do provide that energy the water will move. At some point I suppose the pressure will get so high the water will solidify in the pipe though?

You're missing the fundamentals of physics.

Before (way way way before) the water solidifies you will reach the maximum pressure that a given pump can deliver.

If you think the little 1/2 horse sump pump you can buy at home Depot will push a column of water up to the stratosphere then I have a bridge to sell you.

Who said anything about 1/2 a horsepower? I’m talking about the most powerful pump in the universe, both (known and unknown). How far up an unbreakable column can that pump push the water? And then, what if you make it just a little more powerful, can the water hypothetically be pushed higher?
