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.
