2.7 Unauthorised modification and manufacture of
spare parts
Modification or changes to the pump are only permitted following
agreement with the manufacturer. Original spare parts and
accessories authorised by the manufacturer are safe to use.
Using other parts can result in liability for any resulting
consequences.
2.8 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.
If the assumption is made that a safe operation is no longer
possible, switch off the pump and protect it against
unintentional operation.
This action should be taken
• if the pump has been damaged.
• if the pump no longer seems to be operational.
• if the pump has been stored for an extended period of time in
poor conditions.
2.9 Safety of the system in the event of a failure in the
dosing system
DMH 25X 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.
3. Technical data

DMH nameplate
Note
Explosion-proof pumps are identified from the pump
and motor nameplates. An EC declaration of
conformity is provided in accordance with the EC
directive 2014/34/EU, the so-called ATEX directive.
This declaration of conformity replaces the
declaration of conformity in this manual.
Warning
To operate a pump which has been identified as an
explosion-proof pump for the dosing of inflammable
media or for operation in potentially explosive
operating sites in accordance with the EC directive
2014/34/EU, refer to the enclosed manual
