Pressure in fluids and gasses is dependant of the density of the fluid/gas and the height.
So a small tube at 10m high has the same pressure on the bottom as a 10m deep pool filled with water. So you don't need alot of water to get tremendous pressure, think of pascal's barrel... He made a barrel explode by using a tube of 10m high or something of only a millimeter wide and adding one drop of water to make the barrel explode.
I was just thinking, I recall that people sometimes run pumps in series because the second pump gets more head pressure supplied by the first pump.
Now if you put a very high column acting as a reservoir right over the intake of the pump, would that give a similar result, or does the added pressure get nullified because the pressure is also increased inside the loop?
Something like this:

INTAKE
But very high, like a few metres.
If it does work, some sort of passive pressurizer could also be used, like a column of a high density fluid like mercury...
Is this free pump performance or am I thinking wrong?
