Abstract (en)
[origin: WO2012139898A1] The invention relates to a diaphragm pump having a delivery space which encloses a working volume, at least one deflectable diaphragm which can be moved into a suction position and a pump position, an inlet valve arranged on a suction side of the diaphragm pump and an outlet valve arranged on the pressure side of the diaphragm pump. In order to make it possible to deliver fine-grain powder, in particular also non-flowable powders having particle sizes of 0.01 µm to 100 µm, using a diaphragm pump, it is proposed that a gas feed for introducing a gas into the delivery space be arranged at the delivery space. In addition, the invention relates to a method for delivering fine-grain powder.
