how a centrifugal pump is working?

Answer Posted / deep

centrifugal pumps work by converting the kinetic energy of
a liquid into pressure energy.it does this by means of two
major components,i.e the impeller and the diffuser.as the
impeller is rotated by means of a motor or engine,a low
preesure region is created at the impeller eye causing the
liquid to be sucked into the eye.as the impeller rotates
the sucked fluid is thrown out with force through the
periphery of the impeller.now the diffuser comes into
action.the diffuser due to its shape of varying xsectional
area causes the liquid to slow down and from bernoullis
principle, a reduction in kinetic head will be compensated
by an increase in pressure head.thats basically how it
works.
