Zusammenfassung:	The invention concerns a method and an apparatus for operating a multi-phase pump which has a suction-side inlet (10) and a discharge-side outlet (20) and which pumps a multi-phase mixture charged with solids, comprising the following steps:a. pumping a multi-phase mixture into a discharge-side separation chamber (45),b. separating a gaseous phase from a liquid phase and a solid phase in the separation chamber (45),c. separating the liquid phase from the solid phase in the separation chamber (45), andd. supplying a portion of the liquid phase freed from the solid phase to the suction side.
