Hydraulic pump, aka water pump, is a machine which converts the kinetic energy of the rotating blades into the pressure energy of the water. This pressure energy helps the water reach high altitudes where it is stored in an overhead tank or pumped to ground level and used for various purposes such as irrigation, cleaning drainage.. etc.

Inside the pump casing, there are impeller blades which rotate at high speeds. This causes water to experience a centrifugal force as it is pushed towards the outer edge of the casing. At one point the water enters the delivery tube.
The delivery tube is an increasing diameter tube.
The reason for this is that, according to Bernoulli ‘s principle, as the area increases, speed decreases, but the pressure head increases.. thus this is where the kinetic energy of the water is converted to pursue energy.
The different types of pumps function differently and are used in varied applications.
