Beschreibung
Zusammenfassung:	The invention relates to a pump (1) comprising a pump feed tube (13) for transporting a heat exchange medium (6) for a reactor containing a bundle of catalyst tubes (2). The pump (1) has a housing (14) that surrounds the pump feed tube (13) and comprises an opening (15) in the lower part of the housing (14), which allows the heat exchange medium (6) that is drawn from the lower section of the reactor by the pump (1) to flow into the housing (14). The medium flows upwards in the section lying between the internal wall of the housing (14) and the external wall of the pump feed tube (13), optionally over a heat exchanger (18) and into the interior of the pump feed tube (13) via an opening (16) in the upper section of said pump feed tube (13). The medium then flows through the pump feed tube from top to bottom, into the reactor via an opening (17) in the lower section of said tube (13) and into the upper section of the intermediate chamber between the catalyst tubes (2).
