2.3. Start-up
Before start-up of the pump anyone should acquaint oneself with the explanations of the chapter
troubleshooting (see page 15). 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.
Prior to each use we recommend to flush the pump with a proper fluid (e.g. water or buffer).
Prior to the very first use it might make sense to clean and sanitize the pump chamber. 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..
Recommendation: Test run prior first use!
Before using your pump in your process perform a test run to get used to the specific
properties of the pump.
Please note:
ALMATEC Maschinenbau GmbH is also building custom-made pumps and set-ups.
These modified pumps can be different from this one that is described in here. However the basic
information is applicable to all of the Quattroflow 20k Series pumps. Please do not hesitate to contact
us for further information.
Pay attention to a sufficiently dimensioned piping. A too small piping of the
suction line can cause cavitation as well as a loss of performance.
If hoses were used in the suction line, make sure that they do not collapse due
to the negative pressure.
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 (see 4.1.).
During start-up pay attention to the warning and safety instructions of the
following chapter 3 of this manual.
2.4. Cleaning (CIP)
Cleaning of the single-use pump chamber is not provided, since they are replaced after use.
2.5. Gamma Irradiation
The single use pump chamber can be gamma irradiated with a maximum dose of 50 kGy.
