Safety / Storage and transport / Assembly and installation
• Always depressurise liquid end before working on the pump.
• Always empty and rinse the liquid end before working on the
pump if used with hazardous or unknown feed chemicals.
• Wear safety equipment appropriate to the metering chemical
when working on the liquid end.
• Never let the pump work against a significantly increased
operating pressure or a closed stop tap on the discharge-side.
This can cause lines to burst.
• Avoid overfeed due to positive pressure difference between in
take and discharge sides. E.g. use a ball check valve with at least
1.5 bar opening pressure with an atmospheric pressure outlet
(not 0213).
• Assembly and installation of ProMinent
®
metering pumps with
non original parts, which have not been checked and
recommended by ProMinent is not allowed and can lead to harm
to persons or property for which no liability can be accepted.
• Note all national directives which apply to the installation.
The sound pressure level is < 70 dB (A) at a distance of 1 m in
accordance with EN 23741 or EN 23742 at maximum stroke, maximum
stroke rate, maximum back pressure (water)
3 Storage and transport
Ambient conditions for storage and transport:
Storage and transport temperature: -10 to +50
° C
Humidity: < 92 % rel. humidity,
non-condensing
4 Assembly and installation
IMPORTANT
• The pump must not vibrate when installed.
• Solenoid metering pumps tend to overfeed if the back pressure is
too low. In this case fit a ball check valve, a multifunction valve or
a discharge valve with 1.5 bar opening pressure downstream
from the pump (not 0213).
