Venting

Fig. 9.1
Set metering quantity by means of stroke adjustment downstream of suction to the
metering quantity set upstream of venting (See Section 9.3).
The compressed-air supply can also be switched on and off instead of repeated pressing
NOTE
of the manual button.
If the system is supplied with compressed air, a metering stroke will be carried out by
WARNING
pressing the manual button with the venting lever turned clockwise (metering). This may
cause undesired overconcentrations!

Pos Description
1 Venting lever
2
Manual push button
3 Stroke adjuster
4 Venting line
Charge the system with compressed air:
Using the stroke adjuster, set metering amount to
100% (see chapter 9.3).
Turn venting lever (pos. 1) to the left to 'Vent'
(Arrow points downwards).
Press the manual push button (pos. 2) repeatedly until
the metering material comes out of the return line
(pos. 7) without any bubbles. (Pressing the manual
button = suction stroke, releasing = metering stroke).
Turn venting lever to the right to 'Metering' .
(Arrow points upwards).
Connect pump ready for operation on delivery
side (operation-specific pipe length incl. all
pressure-maintenance valves, injection valves
etc. connected during normal operation).
Set the pump stroke to the required metering
quantity (see Section
quantity)
Fill suitable measuring cylinder with the product
to be metered and insert suction pipe.
Run the pump for exactly 1 minute at the normal
operating cycle frequency.
(max. cycle frequency = 2 cycles / sec.) and
measure the quantity sucked out of the
measuring cylinder.
The value calculated in l multiplied by 60 equals the
actual metering quantity in l/h.
If necessary, adjust the metering capacity by
adjusting the stroke (see Section 9.3) and
repeat capacity measurement procedure.
