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).
The direction of rotation of the motor has to be chosen in that
way that the tension roller is not located on the load side. The
arrow in the figure shows that the motor shaft must rotate
clockwise.
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 5050SU 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.
