Without a pump in this system, the liquid would move in the opposite
direction because of the pressure differential.
Pumps are also used to move liquids from a low elevation into a higher
elevation, and to move liquids from one place to another. Pumps are

How do pumps work?
The fluid arrives at the pump suction nozzle as it flows through the
