2.9 Attention! Warning precautions!
These warning precautions are to prevent the user from an inadmissible
mode of operation. These warning precautions are to be strictly followed
to avoid any damage of the pump and/or any danger to personnel.
Diaphragm pumps are positive displacement pumps and can theoretically generate an infinitely
high pressure. With the discharge line closed, for example by clogging or by incidental closing
of a valve, the pressure generated by the pump may reach a multiple of the admissible pressure
of the plant. This may lead to bursting of the diaphragm or lines which must be absolutely
avoided especially when handling dangerous products.
Diameter of the suction line need to be sufficient to avoid cavitation.
The use of a safety device (i.e. pressure switch) can be necessary.
Please make sure that prior to the start of the pump the discharge line is checked. Make sure that there is
no flow restriction in the discharge line to avoid any over pressure (i.e. closed valve).
Check all seals (i.e. TC clamps) before starting the pump.
The maximum discharge pressure depends on the temperature of the fluid.

Please allow the pump to cool down after heat treatment (i.e. CIP / SIP).
Flush the pump prior to use with appropriate fluid (i.e. buffer)
Foundation design: The foundation must be designed so that it can take the weight of the pump
aggregate on the entire surface.
Please make sure that the pump is operated with the proper mains voltage and frequency to avoid
damages and electrical danger.
Make sure that the slots for the cooling air are not blocked.
Due to the versatile possibilities to use the Quattroflow Q20k pump it is highly recommended
to check case by case if the Quattroflow Q20k pump will be the right tool for the specific
application. The user/operator is responsible to perform a proper method of testing if the
pump should be applied for his specific application.
The chemical and thermal compatibility of the elastomeric parts of the pump with the fluid that will be pumped
are to be checked by the operator before the first process run.
For example, oily, fatty fluids or solvents might cause a swelling and/or destruction of the elastomers.
If in doubt, please contact the manufacturer!
Operating the pump in humid or aggressive air can cause damages to the motor and control box.
The control box should not be exposed to spray/splash water or to heat sources.
If the Quattroflow Q20k pump is to be used under rough conditions (i.e. high-pressure cleaners, exposed to
sea water), the manufacturer can supply special equipment, like motors and controls.
