Abstract
A powder metering apparatus for making available a powder, in particular for powder coating, and which comprises a metering pump with a rotatably driven metering disk arranged between two lateral plates. The metering pump includes an inlet, through which it receives a powder-air mixture, and an outlet that connects via a suction tube to an injector pump. From the outlet, the powder-air mixture conveyed by means of the metering disk to the outlet is sucked out by a vacuum flow that is generated in the injector pump and enters the metering pump via a suction inlet opening, and the powder-air mixture is then supplied to a consumer.
