Abstract

A discharge pump (14) is submersible in the cargo of a cargo tank (10) of a ship via a well (12) at the bottom (11) of the ship's cargo tank (10). A stripping pipe (28) runs from the discharge side of the pump to a delivery location (A, E) via upper deck (22) of the ship. The pump (14) has an impeller (15) which is equipped with opposite pairs of locally defined blades (33, 34), which are disposed downstream just within inlet (13) of the pump (15), the stripping pipe (28) is supplied with pressure medium at a first, lower level and communicates with a pressure medium and/or vacuum source at least at a second, higher lying level of the stripping pipe (28).
