Some centrifugal pumps contain diffusers.
A diffuser is
a set of stationary vanes that surround the impeller. The purpose of the diffuser is to increase the efficiency centrifugal pump by
allowing a more gradual expansion and less turbulent area for the liquid to reduce in velocity. The
diffuser vanes are designed in a manner that the liquid exiting the impeller will encounter an ever increasing flow
area as it passes through the diffuser. This increase in flow area causes a reduction in flow velocity, converting kinetic energy
into flow pressure.
