Fig. 9 Adjusting the stroke
7.6. Adjusting the stroke volume
The stroke volume, and thus the metering volume of the pumped
media, can be adjusted by turning the calibrating screw (see Fig. 9
,
item 1
) at the bottom of the pump.
Calibration range of metering volume per pump stroke: 30
– 80 μl.
A 5 mm Allen key is required to adjust the stroke.
7.7. Adjusting the flow rate
The flow rate can be adjusted via the stroke volume (
Chapter 7.6
)
or by means of the stroke frequency (
Chapter 7.4
).
For reasons of accuracy the suction time, or the energised time
(SZ), must be kept constant and the stroke frequency must be
adjusted via the exhaust time (DZ) (see
Fig. 7
).
The pumps are checked and set to a suction/energised time of
30 ms by KNF Flodos.
