7.6.1 Dismantling in case of diaphragm breakage

This section refers to fig. 41.
1. Make system pressureless.
2. Empty 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

hose.

5. Remove the cover (9).
6. Loosen screws (8) on the dosing head (7) and

remove with discs.

7. Remove the dosing head (7).
8. Unscrew diaphragm (4) counter-clockwise and

remove with flange (2).

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

or soiled. Clean if necessary.

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

damage. Replace if necessary.

If nothing indicates that dosing liquid has entered the
pump housing, go on as described in section

7.4.3 Reassembling the diaphragm and valves

Otherwise proceed as described in section

7.6.2 Dosing liquid in the pump housing

7.6.2 Dosing liquid in the pump housing

If dosing liquid has entered the pump housing:
•

Send the pump to Grundfos for repair, following
the instructions given in section

.

•

If a repair isn’t economically reasonable, dispose
of the pump observing the information in section

.

7.7 Repairs

After consulting Grundfos, please send the pump,
together with the safety declaration completed by a
specialist, to Grundfos. The safety declaration can
be found at the end of these instructions. It must be
copied, completed and attached to the pump.

If the above requirements are not met, Grundfos may
refuse to accept delivery of the pump. The shipping
costs will be charged to the sender.

Warning
Danger of explosion, if dosing liquid
has entered the pump housing!
Do not connect the pump to the power
supply!

Warning
Danger of explosion!
Immediately separate the pump from
the power supply!
Make sure the pump cannot be put
back into operation by accident!

Warning
The pump housing must only be
opened by personnel authorised by
Grundfos!
Repairs must only be carried out by
authorised and qualified personnel!
Switch off the pump and disconnect it
from the voltage supply before carrying
out maintenance work and repairs!

Caution

The pump must be cleaned prior to
dispatch!
If dosing liquid has possibly entered
the pump housing, state that explicitly
in the safety declaration! Observe
section 7.6 Diaphragm breakage.
