Stroke length adjustment
The desired delivery rate of the dosing pump is set using the stroke
length adjustment. Turning the adjustment knob adjusts the hub length
and so increases or decreases the amount of dosing media from the dos-
ing head.
The stroke length can be adjusted while the pump is running or while it is
turned off (in depressurized condition).

Direction of rotation
Effect
Clockwise
Stroke length is reduced,
delivery rate decreases
Counter -clockwise
Stroke length is raised, delivery
rate increases
Table 24: Stroke length adjustment
The scale on the stroke length adjustment shows the value of the setting
in percentage terms from 0% (stopped) to 100% (maximum possible
stroke length).
