When operating as a liquid / liquid centrifugal separator, a mixture of two immiscible liquids (shown in green) with different densities is fed to the pumping chamber located on the bottom of the centrifuge housing. The liquid / liquid mixture is aspirated into the centrifuge bowl by a pumping turbine located on the bottom of the rotating bowl.

The liquids are separated by the centrifugal force generated by the rotating bowl. The heavier liquid (shown in yellow) occupies the outer portion of the bowl. The light liquid (shown in blue) occupies the inner portion of the bowl. The position of the liquid / liquid interphase is regulated by a heavy phase weir. Interchangeable heavy phase weirs of different diameters accommodate a wide range of density ratios. The heavy phase underflows to a static receiving chamber. The light phase overflows to a separate static receiving chamber.

The liquids are discharged by gravity to downstream equipment. Low mix pumping turbines are available for shear sensitive applications.
