6.3 Mounting of Pump Head

6.3.1 Preparation
After removal of the pump head from its packaging
assure that no metallic part is magnetically
attaching. Specifically remove the Fixation Disc,
which comes delivered within the packaging in order
to magnetically fix the impeller against movements
during transportation.

Assure that the impeller speed is set to 0 rpm and
that the system is disabled.
6.3.2 Step 1: Insertion
Pull the Locking Pin radially outwards and insert the
pump head at the same time.

6.3.3 Step 2: Rotation and Snap-In
Smoothly rotate the pump head clockwise until the
Locking Pin snaps in.
6.3.4 Step 3: Ready-to-Use Check
Check that the Locking Pin is properly snapped in
and that the green labeling on the Pump Head
Socket, beside the outlet, is visible.

6.4 Removal of Pump Head

6.4.1 Preparation
Set the speed to 0 rpm and disable the system. After
running at higher motor or liquid temperature the
pump head might stick to the motor due to thermal
expansion effects. Let the system cool down before
starting the removal procedure.
6.4.2 Step 1: Pull Pin and Rotate
Pull the Locking Pin radially outwards and rotate the
pump head smoothly counterclockwise as far as
possible.
6.4.3 Step 2: Axial Removal
Smoothly remove the pump head axially.
6.4.4 Step 3: Usage of Fixation Disc
It is recommended to attach the Fixation Disc (see
Figure 33) to the pump head bottom in order to
minimize magnetic leakage fields surrounding the
impeller and hence reducing the tendency to attract
other magnetic parts.

6.5 Assembly into Hydraulic Circuit

The following points shall be considered, when
integrating the pump head into a single-use circuit.
6.5.1 Usage of Fixation Disc
During handling, assembling and transportation of
the pump head with the hydraulic circuit, it is
recommended to attach the Fixation Disc (see
Figure 33) to the pump head bottom. The disc holds
the impeller mechanically in place and reduces the
magnetic fields, which can attract other magnetic
parts during handling,
transportation.
6.5.2 Handling of Multiple Pump Heads
Be aware of the magnetic forces of the impellers
when handling multiple pump heads at the same
time. Avoid two pump heads coming together with
force due to the magnetic attraction, which might
cause cracks.
6.5.3 Avoidance of Mechanical Stress
Avoid applying too much mechanical stress to the
pump head for example, by excessively squeezing
it with the other parts of the circuit to a packaging
or an enclosed space of limited size, or by
applying too much tension or perpendicular force
to the fittings.
