5.8 Improper operating methods
The operational safety of the supplied pump is only ensured if it is
used in accordance with section
. The specified limit
values must under no circumstances be exceeded.
5.9 Safety of the system in the event of a failure in the
dosing system
DMX 221 dosing pumps are designed according to the latest
technologies and are carefully manufactured and tested.
However, a failure may occur in the dosing system. Systems in
which dosing pumps are installed must be designed in such a
way that the safety of the entire system is still ensured following a
failure of the dosing pump. Provide the relevant monitoring and
control functions for this.
