CAUTION
Magnetic Forces
Pay attention to the magnetic forces when handling the
pump head. It has to be avoided that magnetic parts
are attracted, which
contamination. Specifically pay attention to the
magnetic forces, when handling two pump heads at the
same time.
CAUTION
!
The rotating impeller could cause injury. Do not run
the pump system when opening the pump head.

6.3 Replacement of Pump Head

6.3.1 Preparation
After removal of a new pump head from its packaging
assure that no metallic part is magnetically attaching to
the pump head. Before insertion into the motor remove
the Fixation Disk, which comes delivered with the
packaging in order to magnetically fix the impeller against
movements during transportation.
Figure 34: Metallic Fixation Disc
6.3.2 Power Down the System
Set the speed to 0 rpm, disable the system. After running
at higher motor or liquid temperature the pump head
might stick to the motor due to thermal expansion effects.
In this case let the system cool down for a while before
starting the replacement procedure.
6.3.3 Pump head Removal from Motor
Un-tighten the screws M1 to M4, which fix the pump head
to the motor (see Figure 35). Do not use the pump
housing screws P1 to P6. Remove the pump head axially
and attach the Fixation Disk from the new pump head to
it.
