Abstract:
A method and a dense phase powder pump for conveying coating powder from a first powder reservoir to a second downstream powder reservoir or to a downstream powder spray-coating gun or the like installation for spraying coating powder are disclosed. In order to reduce the number of components of the dense phase powder pump that require maintenance, the dense phase powder pump is designed as a single-chamber dense phase powder pump and has only a single powder conveyor chamber for conveying coating powder.

Claim (Index 1):
A dense phase powder pump for conveying coating powder in a powder path from a first powder reservoir to a second downstream powder reservoir or a downstream powder spray-coating gun or similar device for spraying coating powder disposed downstream of the dense phase powder pump, wherein the dense phase powder pump is designed as a single-chamber dense phase powder pump and comprises just one single powder conveyor chamber for the conveying of coating powder, wherein:\n at least one auxiliary compressed air inlet device opens into at least one location in the powder path after a powder outlet valve of the dense phase powder pump to supply auxiliary compressed air as additional conveying compressed air as needed, the dense phase powder pump comprises a powder inlet connected or connectable to the first powder reservoir and a powder outlet connected or connectable to the second reservoir or to the powder spray-coating gun or other such mechanism for spraying coating powder, the single powder conveyor chamber comprises a powder passageway at an end region which serves both as a powder inlet and a powder outlet, and the dense phase powder pump further comprises a powder inlet valve by means of which the powder passageway of the single powder conveyor chamber is fluidly connected or connectable to the powder inlet of the dense phase powder pump and the powder passageway of the single powder conveyor chamber is or can be fluidly connected to the powder outlet of the dense phase powder pump by means of the powder outlet valve.
