Abstract

An unloading pump (14) is submersible in the cargo in a cargo tank (10a) of a ship. A pump inlet (13) is arranged in a well (12) at the bottom (11) of the tank (10a). The pump (14) comprises a main pump (14a) and an auxiliary pump (14b). the pump (14) has a discharge pipe (26), which is equipped with a closing valve (27). The discharge pipe (26) communicates via an outlet (29) with a stripping pipe (28), which communicates with a valve-controlled downstream delivery location (A). The stripping pipe (28) communicates with an outlet (29) in the snail housing-formed discharge portion of the pump housing. The stripping pipe (28) is equipped with a diffusor (44) for the generation of an extra pressure in the stripping pipe (28). <IMAGE>
