4.4 Function description
Dosing pumps are positive displacement pumps. They are used if
precisely defi ned delivery of a medium is necessary. A constant volume
per stroke or time is delivered.
The system delivers or meters the dosing medium by means of a
repeated sequence of suction strokes followed by pressure strokes. This
results in a pulsing fl ow.
If the dosing pump is in the suction stroke phase, the diaphragm is pulled
into the rear fi nal position. Due to the resulting vacuum in the dosing
head, the discharge valve closes, the suction valve opens and dosing
medium fl ows from the suction line into the dosing head.
If the dosing pump is in the pressure stroke phase, the diaphragm is
moved into the front fi nal position. Due to the pressure in the dosing head,
the suction valve closes and the dosing medium fl ows through the
discharge valve from the dosing head into the pressurised pipe.
