Sump system reservoir and multiphase pumps and methods for separating and splitting a multi-phase mixture

The invention relates to a container for multi-phase mixtures of a hydrocarbon source having at least one inlet (20) for introducing multi-phase mixtures in the collection container (10) and a plurality of outlet ports (30), which are connectable to the pump (3) to be pumped via the multi-phase mixtures, the outlet (30) are inwardly directed, via the sump floor (11) upwardly projecting baffles (40) are assigned which have a first upper opening (42) and a second lower opening (41), wherein the flow cross section of the lower opening (41 ) is smaller than that of the upper opening (42).
