Is it true that you can鈥檛 pump water no higher than 10 meters?

I heard that a really long time ago. Is that actually true or is there a fact like that. I know it has to do with water and 10 meters though.Is it true that you can鈥檛 pump water no higher than 10 meters?
The rule is that you can't DRAW water up more than ~10 m using a vacuum (as, on the suction side of a pump). That's because atmospheric pressure on the water surface is equal to no more than that head of water.





So, your pump must always be less than 10 m above the water surface it's drawing from. Once it gets to the pump, there's no limit as to how high it can be raised from there; depends only on the strength of the pump components.Is it true that you can鈥檛 pump water no higher than 10 meters?
There is a theoretical limit to how high water can be pumped (with one pump).





Have to dig into some theory to get the exact height.
