6.3.4 Mounting 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 Removal 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 Removal Step 2: Axial Removal
Smoothly remove the pump head axially.
6.4.4 Removal Step 3: Usage of Fixation Disc
It is recommended to attach the
Fixation Disc
(see
) 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 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
) 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, sterilization and
trans-portation.
6.5.2 Careful 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 into the packaging or
an enclosed space of limited size, or by applying too
much tension or perpendicular force to the fittings.
