6 Instruction for Use of Pump Head
6.1 Description and Preparation
6.1.1 Description
The LPP-600 Multi-Use pump heads are designed for
applications in the Life Science industries in connection
with the PuraLev
®
600MU pump system components. The
pump head is mounted to the Bearingless Motor (a
MagLev drive motor) and the motor is connected to a
controller generating the currents for rotation and the
levitation of the impeller.
Figure 36: Pump heads LPP-600.7/18/27 and motors LPM-600.x
(For other configurations refer to relevant drawings.)
Before using the LPP-600 Multi-Use pump heads make
yourself familiar with the following warnings, cautions and
instructions.
6.1.2 Inspection Prior to Use
The pump head should be inspected prior to use for any
damage. Do not use the pump head if any damage is
found. Contact Levitronix
®
regarding return of any
suspected pump head.
6.1.3 Traceability for Troubleshooting
Traceability for trouble shooting is assured with a 6-digit
serial number located on the top of the pump head (see
Figure 38).
6.2 General Warnings and Cautions
High Magnetic Field Strength of Pump Impeller.
The pump head contains a rotor magnet with high
magnetic field strength. Pace maker may be influenced
and magnetic field may lead to contusions. Keep
distance to pace makers and handle pump-heads with
care.
Magnetic Forces
Pay attention to the magnetic forces when handling the
pump head. It must be avoided that magnetic parts are
attracted, which can cause cracks or contamination.
Specifically pay attention to the magnetic forces, when
handling two pump heads at the same time.
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 37: 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 38). 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.
