What are Axial pumps ? How do they work ?

Axial pumps are pumps with a rotary impeller.  The impeller drives the water as a result of which the water gains kinetic energy.  In this aspect, it is similar to a centrifugal pump.

The Axial pump differs from the centrifugal pump in the direction of the water flow.  In a centrifugal pump, the water is radially moved towards the casing.  Here, however, the water is moved axially. That is, it is moved in a direction parallel to the axis of the impeller.  The water is not radially displaced.

The impeller of the axial pump is designed like a curved propeller which pushes the water upwards.
