Diaphragm Pump N1200.12, N1400.1.2.12 Safety
Translation of Original operating and installation instruction, English, KNF 308930-308933 02/22 7
2.3 Working in a safety conscious manner
Observe the regulations on accident prevention and safety during all work
on the pumps and during operation.
Avoid contact with the pump heads and housing parts because the pump
heats up during operation.
When working on the pump, make sure that the pump is disconnected
from mains and without power.
When connecting the pump to the electrical mains, observe the corre-
sponding safety rules.
Ensure that no hazards arise from gas flowing when gas connections are
open, from the effects of noise or from hot, corrosive, dangerous and envi-
ronmentally hazardous gases.
Make sure that an EMC-compliant installation of the pump is ensured at all
times to prevent the occurrence of dangerous situations.
Double diaphragm system For pump models with a double diaphragm system, a second diaphragm is
located below the working diaphragm. This safety diaphragm is under less
strain during pump operation, i.e. it is under significantly less tension than
the working diaphragm.
In the event of a defect to the working diaphragm, no gas can escape from
the pump. The closed safety space between the two diaphragms can be
monitored to immediately detect damage to the working diaphragm. In
such a case, the pump must be brought to a standstill within 24 hours by
the system owner and the working and safety diaphragm must be re-
placed.
2.4 Operating conditions
Only use the pump in perfect technical condition, for its intended purpose,
safely and with an awareness of the dangers and in observation of the op-
erating instructions.
Protect the compressors with a pressure relief device between the pres-
sure side of the compressor and the first shut-off valve.
Only install and operate the pumps in accordance with the operating pa-
rameters and conditions described in Chapter
3 Technical data .
Only pumps that are fully assembled and in the condition as delivered may
be operated.
Make sure that the installation location is dry and that the pump is pro-
tected from rain, splash water, gushing water, dripping water and other
contamination.
Check the tightness of the connections between the pipes of the applica-
tion and the pump (or the connection of the pump) at regular intervals.
Leaky connections carry the risk of releasing dangerous gases and vapors
from the pump system.
2.5 Media
Requirements of pumped media Before transferring a medium, check whether the medium can be trans-
ferred without risk in the specific application.
Take note of any change in the state of matter (condensation, crystalliza-
tion).
Before using a medium, check the compatibility of the media-contacting
components (see
3 Technical data ) with the medium.
Only transfer gases that remain stable under the pressures and tempera-
tures that arise in the pump.
