Fig. 4: Pump head
The pump transfers, compresses (depending on pump version)
and evacuates gases and vapors.
The elastic diaphragm (
4
) is moved up and down by the eccentric
(
5
) and the connecting rod (
6
). In the downward stroke it aspirates
the gas to be transferred via the inlet valve (
2
). In the upward
stroke, the diaphragm presses the medium out of the pump head
via the outlet valve (
1
). The transfer chamber (
3
) is hermetically
separated from the pump housing (
7
) by the diaphragm.
