5Notes on safety
WARNING
•The pumps must be accessible any time for operation and maintenance, access may not
be hindered or blocked!
•Pneumados metering pumps can be operated with a max. permissible air pressure of 8
bar. Corresponding measures have to be taken to ensure that this pressure is not
exceeded – if required by installing a safety valve or a pressure limiting valve upstream
of the pump!
•Always rinse the liquid end first before commencing maintenance and repair work if
hazardous or unknown metering media are used!
•When metering hazardous or unknown metering media, suitable protective equipment
(goggles, gloves …) must be worn when working at the liquid end! Observe the safety
data sheets of the metering media!
•Switch off the pump control and close the compressed air supply line first before
starting any work at the pump! Always depressurise the metering line! Always empty
and rinse the liquid end! Observe the safety data sheets of the metering media!
Proper use •The pump is only designed for metering liquid media.
•All other uses or modifications are prohibited!
•The pump must not be used to meter gaseous media or solids.
•The pump is not designed for use in Ex areas.
•The pump may only be used in compliance with the technical specifications stated in the
operating instructions and in the technical data.
•The pump may only be operated if all components were installed in compliance with the
technical documentation and a proper installation was performed.
•The pump may only be operated by trained personnel.
IMPORTANT
•Settings should only be made with the pump in operation – when the adjustment pin of
the metering stroke is momentarily relieved!
•Only use the clamping rings and hose grommets specified for the corresponding hose
diameter as well as genuine hoses of the specified hose dimensions and wall thicknesses.
Otherwise, the stability of the connection is not guaranteed!
•Avoid reducing the hose sizes! In case of long lines and viscous media, the next higher
line cross-section or a pulsation dampener should be used!
