Abstract: A flow-ducting system with a combined pump-drive module, the pump-drive module including a drive module, and a pump module having an impeller that can be driven by the drive module, the unit including a casing having at least one inlet side and at least one outlet side and a moveable shut-off device arranged between them, a flow path between the inlet side and the outlet side being formed in at least one position of the shut-off device, and the pump module being arranged in the flow path between the inlet side and the outlet side. In at least one further position of the shut-off device (10, 10?), the unit (1) is capable of shutting off the flow path (9) in such a way that the shut-off device (10, 10?) and the unit casing (2) form an area (20), which is separated from the flow path (9) and which is sealed off from the inlet side (5) and the outlet side (6), and the pump-drive module (11, 11?) is arranged at least partially inside this area (20).
