Instruction for Use of Pump Head 

6.1  Description and Preparation 

6.1.1  Description 

The 

LPP-200  Multi-Use

  pump  heads  are  designed  for 

applications in the Life Science industries operating with 
the 

PuraLev

®

  200MU

  pump  system.  The  wetted  parts 

are made out of biocompatible materials (FDA, USP VI, 
Animal-Free).  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 32: Pump head LPP-200.17 with motor BSM-1.x 

Before  starting  using  the 

LPP-200  Multi-Use

  pump 

heads make yourself familiar with the following warnings, 
cautions and instruction. 

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 34

). 

6.2  General Warnings and Cautions 

 

 

! 

 

WARNING

 

 

 

 

 

 

High Magnetic Field Strength of Pump Impeller 

The  pump  head  contains  a  rotor  magnet  with  high 
field  strength.  Pace  makers  may  be  influenced  and 
magnetic field may lead to contusions. Keep distance 
to pace makers and handle pump heads with care.

 

 

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  can  cause  cracks  or 
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 33: 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 34

). 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.
