A cleaning in place system and a method of cleaning a centrifugal separator

The invention relates to a cleaning in place system (1) for a centrifugal separator and a method of cleaning a centrifugal separator, which centrifugal separator (2) comprises a rotor (3) having a separation space (4), a separator inlet (5) and a first separator outlet (6). The first separator outlet comprises an outlet pump (7) configured to provide a flow of fluid from the first separator outlet. The cleaning in place system further comprises a container (10) for cleaning fluid, a cleaning fluid pump (11) for providing cleaning fluid from the container to the separator inlet, such as an eductor. The cleaning in place system is configured to receive a flow of fluid from the first separator outlet and that the cleaning fluid pump is configured to pump cleaning fluid from the container to the separator inlet by means of the received flow of fluid.
