8.3.2 Dismantling the diaphragm and valves

Before dismantling, read section Diaphragm
breakage and section Operation with loose dosing
head screws thoroughly.

Warning
Danger of explosion, if dosing liquid has
entered the pump housing!
If the diaphragm is possibly damaged or if
the pump was operated with damaged or
loose dosing head screws, don’t connect
the pump to the power supply!

This section refers to fig. Dosing head, exploded
view.
1. Make system pressureless.

2. Empty the dosing head before maintenance and

flush it, if necessary.

3. Take suitable steps to ensure that the returning

liquid is safely collected.

4. Dismantle suction, pressure and deaeration

hoses.

5. Unscrew deaeration valve.

6. Dismantle valves on suction and discharge side

(4, 6).

7. Loosen screws (7) on the dosing head (5).

8. Remove the screws, in case of PP or PVDF

dosing head together with the front plate (8).

9. Remove the dosing head (5).

10. Unscrew diaphragm (3) counter-clockwise and

remove it.

11. Make sure the drain opening (9) is not blocked or

soiled. Clean if necessary.

12. Check the safety diaphragm (1) for wear and

damage.

If nothing indicates that dosing liquid has entered the
pump housing, and if the safety diaphragm is not
worn or damaged, go on as described in section
Reassembling the diaphragm and valves. Otherwise
proceed as described in section Dosing liquid in the
pump housing.

8.3.3 Reassembling the diaphragm and valves

Caution

Please observe as well sections
Installation, Priming/venting of pump and
Start-up!

The pump must only be reassembled, if nothing
indicates that dosing liquid has entered the pump
housing. Otherwise proceed as described in section
Dosing liquid in the pump housing.
This section refers to fig. Dosing head, exploded
view.
1. Screw on new diaphragm (3) clockwise.

2. Attach the dosing head (5).

3. Install screws (7), in case of PP or PVDF dosing

head together with the front plate (8), and cross-
tighten with a torque wrench.
• Torque: 5.5 Nm (+0.5 / -0 Nm).

4. Install new valves (4, 6).

• Observe the flow direction (indicated by an

arrow on the valve)!

5. Install the deaeration valve.

6. Connect suction, pressure and deaeration hoses.

Caution

Cross-tighten the dosing head screws
with a torque wrench once before
commissioning and again after 2-5
operating hours at 5.5 Nm (+0.5 / -0
Nm).

7. Deaerate dosing pump (see section Priming/

venting of pump)
