Fig. 2: Working principles
Diaphragm fluid pumps are based on reciprocating displacement
pump technology. An elastic diaphragm (4) is moved up and down
by the eccentric (5) and the connecting rod (6). During the down
stroke, the diaphragm sucks in the medium through the inlet valve
(2). During the up stroke, it forces medium out of the pump head
through the exhaust valve (1). The diaphragm hermetically seals
off the working chamber (3) from the pump drive (7).
