Upon cleaning of a relatively heavy liquid from small amounts of relatively light liquid the liquids are first introduced into a container (1), in which the light liquid is allowed to collect on the surface of the heavy liquid. Then a surface layer of the liquid body (4) in the container (1), constituting a mixture of the two liquids, is brought to flow over an overflow outlet member (14) into a collecting chamber (15). From the collecting chamber (15) the liquid mixture is pumped further on to a centrifugal separator, from where cleaned relatively heavy liquid is returned to the container (1). According to the invention the liquid mixture is pumped from the collecting chamber (15) to the centrifugal separator by means of a pumping member (17), which is connected with the rotor (16) of the centrifugal separator and, thus, rotates therewith. Hereby, the cleaning operation in question may be performed by means of a simple and non-expensive device.
