START-UP OPERATIONS
Before start-up of the pump anyone should acquaint oneself with the explanations of the chapter
troubleshooting. Only by this the defect quickly can be realized and eliminated in case of trouble. Problems
which cannot be solved or with an unknown reason should be passed on to the manufacturer.
Before using your pump in your process perform a test run to get used to the specific
properties of the pump.
During start-up pay attention to the warning and safety instructions in the user manual.
5.1
Mounting the pump
All QF standard pumps are mounted on a stainless steel base plate. If you are using an “OEM” pump version
without base plate the pump has to be fixed with the provided mounting.
When installing the pump please consider that around the pump enough space is available for operation and
maintenance. Pay attention to the required space needed for assembly and disassembly of the pump
chamber.
5.2
Mounting the pump chamber
If you have ordered a complete QF pump the stainless steel pump chamber is built-on ex works.
If you have ordered a Quattroflow Single-Use Pump or just a Single-Use pump chamber, the chamber will be
supplied separately. The front crews and the clamping ring screw have to be tightened with the defined
torque which is given in the user manual.
Single-Use Pump chambers must be assembled with the respective pressure plate made of stainless steel.
Please check the given torque for front screws and clamping ring screw in the user manual. If
the clamping ring screw is not fixed before operation the pump could damaged.
It is not possible to use single-use pump chambers without pressure plate.
5.3
Cleaning before start-up (Multiple-Use, Stainless Steel pump chamber)
All Multiple-Use pump chambers made of stainless steel are not cleaned or sterilized ex works. For this
reason prior to the very first use it might make sense to clean and sanitize the pump chamber.
Prior to each use we recommend flushing the pump with a proper fluid (e.g. water or buffer). A commercial
caustic cleaner and/or 0.1N to 0.5N NaOH can be applied. The chosen cleaning agent can be recirculated and
also stored inside the pump chamber. For flushing out of any cleaning agent do not recirculate! Check with
appropriate analytical methods the success of the flushing procedure.
For further cleaning procedures see chapter Cleaning.
