4.1. Replacement of the pump chamber
The Quattroflow 150SU pump is designed for use in single-use processes. The wetted pump chamber
made of plastic can be replaced quickly and easily. The simple disposal of the pump chamber saves
time and money because the cost of cleaning, sterilization or a sophisticated cleaning validation is
inapplicable. To each new pump unit three single-use product chambers will be delivered. More can
be ordered as a set of three pieces (PQ15DISPP).
The replacement of the pump chamber can be conducted by the operator. Please follow the drawings
for the installation and deinstallation.
Before starting the disassembly ensure that the pump is not in operation and can not be
accidentally taken into operation. Also, make sure that the system was emptied before
the change.
