7.5 Notes on dismantling
All repair and maintenance work is to be performed by
skilled staff using appropriate tools and original spare
parts.
Is the necessary documentation available?
Has the pump been taken out of operation, evacuated
and flushed correctly? See also
Section 6.3.
7.5.1 Protective clothes
Even if the pump has been properly evacu-
ated and rinsed, residue of the medium may
still remain in the pump. Example: Between
sealing surfaces or in the bearing seats.
Protective clothing in accordance with the
regulations is to be worn.
Protective clothing is also to be worn even if only the
bearing pedestal is to be removed. It may be that me-
dium has penetrated into the lantern chamber through
the can.
7.5.2 Magnetic fields
Caution! Strong magnetic fields
Risk during dismantling and in the vicinity of magnetic
drives as single parts.
Remove loose parts and other magnetisable metals
from the work bench. They could otherwise be at-
tracted :
Risk of accident !
Place any tools needed at a safe distance.
Keep electronic equipment and measuring instru-
ments at a distance. In cases of doubt ask the equip-
ment manufacturer.
Hold magnetic drives as single parts firmly or secure.
Otherwise, they could be attracted, for example, by a
vice:
Risk of accident !
People with an artificial pacemaker
Keep torso
at a minimum distance of
500 mm .
Mechanical watches and electric data carriers as well
as digital watches or pocket calculators:
150 mm distance .
Data carriers such as credit cards, cheque cards, ID
cards with magnetic strips or magnetic tapes:
150 mm distance .
7.5.3 Changing the radial ball bearings
When changing the radial ball bearings, you merely
need to remove the bearing pedestal from the plant.
For removal and dismantling of the bearing pedestal,
see
Sections 7.6.1 and 7.6.2 .
7.6 Dismantling
There are three possibilities for dismantling:
1. Dismantling the entire pump from the plant.
2. Dismantling the entire slide-in unit, i.e. the housing
remains in the plant.
3. Removing only the drive section, i.e. the pump
does not need to be drained (back-pull-out design).
See
Section 5.8 .
Dismantling of the entire pump is described.
¾
Secure pump on a workbench or worktop with the
suction nozzle facing downwards.
¾
Screw ring bolt M8 into the drive shaft.
7.6.1 Removing bearing pedestal
Caution! Magnetic forces!
Risk of accident!
Axial forces are produced when the bearing pedestal
is pulled out of the lantern. These forces diminish
again abruptly after it has been removed.
The operating torque of the magnetic coupling in-
stalled is specified on the
type plate .
¾
Undo bearing pedestal screwing 901/1, 554/4 .
¾
Detach the bearing pedestal from the lantern cen-
tering, if necessary using 2 levers.
If required you have the possibility to use the two
threaded holes in the bearing frame for jacking
screws.
Group 1 - M 12
Group 2 - M 14
¾
Raise the bearing pedestal unit off the lantern with
a crane or pull it by hand out of the lantern.
¾
Remove flat gasket 400/1 .
