Water can be pumped without using a pump!.  See the attachment for details.

What is new about this? This works the same way as a medical syringe. Put it in water and pull the rubber piston. Voila, water is going into the syringe.
You face a sub pressure when trying to pull out the inner cylinder due to the weight of the water you want to rise. It works, but it will require energy input to work.

Medical syringe works like a reciprocating pump. When you pull the rubber piston, external atmospheric pressure straight away acts on the piston.  The idea of keeping both ends of tube V2 open is to prevent atmospheric pressure acting on it.

Please understand the concept before making comments.

looked, understood, and it is a piston pump and air pressure dose act on V2.
when you bend the hose to pull on V2 you create a surface for air pressure to push it back in to
equalize the pressure.
thankyou for playing please play again.

“A very interesting point here to note is that work input to the system is only energy supplied to overcome friction between tube V2 and rubber ring” â€" Quote from AP Pump.pdf

Interesting it may indeed be but not true surely is. Vacuum swortze be with us ;)
