A device for feeding chemically aggressive fluids is composed of a centrifugal pump (7) made of plastic which can be dipped into the fluid and has a radial impeller (14), and of a drive motor (1) which is arranged at a distance from the centrifugal pump (7) outside the fluid. The pump housing (6) is flanged onto the drive motor (1) via a tubular intermediate element (4) and the extended pump shaft (12) is coupled to the motor shaft (8). In order to avoid radial forces which cannot be taken up by the bearing of the drive motor (1) or the motor shaft (8), accompanied by the simplest possible, bearing-free design of the pump housing (6), the pump housing (6) has two outlet connecting elements (18, 19) which are offset with respect to one another by 180 DEG and have the same cross-section and the pump shaft (12) is rigidly connected to the motor shaft (8). <IMAGE>
