Most pumps like centrifugal pumps are limited by atmospheric pressure. This is because the pump simply create a vacuum where the atmospheric pressure pushes the water into it. Hence there is a limit of 10 meters of waters it can acquire due to gravity.
What kind of pump where it is not limited by atmospheric pressure so it can acquire say 20 meters of water?
If there is none in production. Then theoretical. Like for example in certain explosion, great vacuum is created. This can make it suck more than 10 meters of water, right? Or other techniques not limited by existing technology. I just want to have idea how such pump can operate. I googled but didn't get the answer.
