Abstract
A diaphragm pump for pneumatic high-pressure delivery of 1 to 10 MPa of fluidised dusts, in which filling occurs from below via pneumatic suction by hydraulic reciprocating movement of the diaphragm and also by applying a negative pressure. The dust is held in a loosened fluidised state over the entire pump operation, wherein the high-pressure gas requirement is low. A drive of the diaphragm pump by a hydraulic pressure intensifier and multiple diaphragm pumps are operated in a phase-displaced manner with respect to each other. A dust delivery system which uses the diaphragm pump is operated with a low drive power.
