Displacement pump gives you constant Q but different head ( pressure ) as required . centrifugal pump gives different Q

positive displacement pump used for high pressure required & centrifugal pump used in case of high flow rate required

displacement pump is a device which deliver a constant volume of liquid for each cycle at varying discharge (Q) pressure or HEAD.

centrifugal pump is a device in which high velocity of the liquid will then produce a velocity head and at the same time producing a high flow rate

In positive displacement pump there is a mechanical variation in chamber.

In dynamic pump there is no mechanical variation in chamber.

In displacement pumps the fluid is confined in the space i.e. within the working boundary of the pump whereas in case of the centrifugal pumps the is not confined within the boundary instead its supplied uniformly and steadily to get the required motion.

Displacement pump is a mechanical pump which is converted to mechanical energy to hydraulic energy.

Centrifugal pump is a mechanical device which is converted to mechanical energy to kinetic energy or pressure energy.
