8.4 Adjusting and locking the stroke length
Caution
Adjust the stroke length only while the pump is running!
Adjust the stroke length manually by turning the knob!
Follow the notes for stroke-length adjustment for the relevant pump type!
1. Remove the covering cap from the front of the stroke-length adjustment knob.
2. Use a screwdriver to loosen the locking screw by approximately 2 turns.
3. Increase/reduce the dosing flow while the pump is running.
4. Slowly turn the adjustment knob to the left/right to set the desired dosing volume.
5. Depending on the application, tighten the locking screw so that the adjustment knob can still be turned/cannot be turned any more.
6. Replace the covering cap.
8.5 Notes for stroke-length adjustment
Note
In general, keep the stroke length setting as high as possible, and adjust the flow rate using the stroke frequency.
8.5.1 For automatic deaeration
Caution
Do not set the stroke length to less than 40 %.
Set lower flow rates by reducing the stroke frequency!
• Dosing flow between 40 % and 100 %:
– ideal operating range: quick deaeration, only brief interruption in dosing.
– Over 80 %, the flow rate only increases very slightly.
• Dosing flow between 20 % and 40 %:
– deaeration is slower and unsteady.
• Dosing flow less than 20 %:
– automatic deaeration impossible or limited.

8.6 Adjusting the zero point
The zero point (no dosing) of the dosing pump is factory-set to a counter-pressure of 3-4 bar. If the operating counter-pressure at the injection unit deviates considerably from this value, it is advisable to readjust the zero point to obtain more precise values.
Note
Always adjust the value with the discharge line connected and with operating counter-pressure.
1. Connect the calibration tube to the dosing head on the suction side (except for Plus 3 system).
2. Start the dosing pump.
3. Set the dosing flow to 15 %.
8.7 Calibrating the dosing flow with Plus
3
system
For pumps with Plus
3
system, the current dosing flow can be checked during operation.
Warning
Do not let the calibration tube (E) run empty!
Re-open the isolating valve (D) in due time!
1. Close the isolating valve (D) at the calibration tube (E).
2. The supply from the priming chamber (F) is shut off and the calibration tube (E) is slowly emptied.
3. Using a stop watch, measure the time (t in seconds) it takes to dose 5 or 10 ml of dosing medium, depending on pump type.
4. Re-open the isolating valve (D) at the calibration tube (E).
5. Calculate the dosing flow:
V = = t
V = = t
Fig. 40 Pump with calibration tube
Note
Suction line with reed contact empty signal must remain in the dosing tank!
4. Remove the covering cap from the front of the stroke-length adjustment knob.
5. Use a screwdriver to remove the locking screw.
6. Turn the adjustment knob slowly clockwise
(towards the zero point) until the medium level stops falling in the calibration tube.
7. Remove the adjustment knob by pulling it up, and then reinsert it in the slot so that the indicator on the adjustment knob points to the zero point.
8. Then tighten the locking screw so that the adjustment knob can still be turned.

3. Leave the pump running until the medium flowing from the deaeration line (J) is free of air bubbles.
4. Carefully close the deaeration valve.
8.9 Changing the tank with Plus
3
system
For pumps with Plus 3 system, the tank can also be changed during operation by using the supply of dosing medium in the priming chamber.
Warning
The dosing medium is constantly supplied from the overflow line while the pump is running. Take suitable steps to ensure that the dosing medium is safely collected!
Warning
Risk of chemical burns!
Wear protective clothing (gloves and goggles) when working on the dosing head, connections or lines!
Caution
Do not let the calibration tube (E) run empty!
Changing the tank
1. Remove the suction line, overflow line and deaeration line from the empty tank.
– The dosing medium is then supplied from the tank (F).
2. Insert the suction line, overflow line and deaeration line into the new tank.
3. Do not immerse the overflow line and deaeration line in the dosing medium. Route the lines downwards and without loops.
Note
There is only a limited amount of time available to change the tank, depending on the pump type and dosing flow, e.g. 30 seconds at a dosing flow of 6 l/h!
If air has been sucked in, briefly increase the stroke setting to 100 % and switch the pump to continuous operation.
9. Maintenance
Caution
In the event of a diaphragm leakage, the dosing liquid may leak out of the hole in the intermediate flange between the pump and the dosing head. The parts inside the housing are protected from the dosing liquid for a short time
(depending on the type of liquid) by the housing sealing. It is necessary to check regularly (daily) if liquid is leaking out of the intermediate flange.
For maximum safety, we recommend the pump version with diaphragm leakage detection.
9.1 General notes
Warning
When dosing dangerous media, observe the corresponding safety precautions!
Risk of chemical burns!
