what different between centrifugal pump and positive
displacement pump

Answer Posted / jsjhala

if we require a high pressure and low volume flow rate
than we can use positive displacement(because on that a
simple piston cylinder arrangement are taken so we seeing
less amount of leakage problem)and on centrifugal pump ,its
works on the principle of centrifugal action and its
application on that case if we required high volume flow
rate with less pressure
