Fig.5: Function of a diaphragm pump
Diaphragm pumps transfer, compress (depending on the ver-
sion) and evacuate gases and vapors.
The elastic diaphragm (4) is moved up and down by the ec-
centric (5) and the connecting rod (6). In the downwards
stroke, it aspirates the gas to be transferred via the inlet valve
(2). In the upwards stroke, the diaphragm presses the medium
out of the pump head via the outlet valve (1). The transfer
chamber (3) is separated from the pump drive by the di-
aphragm.
