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 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.
