2.2 Responsibility of the operator
The pumps are produced in accordance with the generally recognized
rules of engineering, as well as the occupational health, safety and acci-
dent prevention regulations. Nevertheless, dangers can arise during their
use that lead to injuries to the user or third parties or to damage to the
pump or other property.
Only use the pumps in perfect technical condition, for their intended use,
safely and with an awareness of the dangers and in observation of the op-
erating and installation instructions.
The components that are to be connected to the pumps must be designed
according to the pneumatic data of the pumps.
When connecting the pumps to the electrical power, observe the corre-
sponding safety rules.
Make sure that no hazardous situation, physical harm or impairment of the
pump can occur.
Operating
parameters
Only operate and install the pump under the operating parameters and op-
erating conditions described in Chapters 2.4 Operating conditions and 3
Technical data.

Diaphragm Pump N0150.12 Safety
Translation of Original operating and installation instruction, English, KNF 308922-308925 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.

Safety Diaphragm Pump N0150.12
8 Translation of Original operating and installation instruction, English, KNF 308922-308925 02/22
Handling of
hazardous
media
Upon breakage of the working diaphragm and/or leaks, the transferred
medium will mix with the air in the inner space between the working di-
aphragm and the safety diaphragm and/or with the air in the surroundings.
Risk of dangerous gas mixtures during pump operation if the working di-
aphragm breaks: Depending on the medium being transferred, breakage
of the working diaphragm can result in a dangerous mixture if the medium
mixes with the air in the innerspace between the working diaphragm and
the safety diaphragm:
§KNF recommends monitoring the innerspace between the working di-
aphragm and the safety diaphragm (see item 5 in Fig. 5) through the
hole(s) in the intermediate ring for a change in pressure. If the pres-
sure changes in the innerspace, the pump is to be stopped immedi-
ately.
§After breakage of the working diaphragm, the pump must be stopped
immediately. Replace the working diaphragm and safety diaphragm
prior to further operation (see Chapter 8 Servicing).
§If pressure or flow rate changes without apparent reason, switch off the
pump immediately and check the pump for damage.
Make sure that a dangerous situation cannot arise as a result.
When pumping hazardous media, observe the safety regulations for the
handling of said media.
Handling of combustible media Note that the pump is not designed to be explosion-proof.
Make certain that the temperature of the medium is always sufficiently be-
low the ignition temperature of the medium so as to prevent ignition or ex-
plosion. This also applies for abnormal operating situations.
Note that the temperature of the medium increases when the pump com-
presses the medium.
Therefore, make certain that the temperature of the medium also remains
sufficiently below the ignition temperature of the medium even when it is
compressed to the maximum permissible operating pressure of the pump.
The maximum permissible operating pressure of the pump is stated in
Chapter 3 Technical data.
Make certain that the permissible ambient temperature (see 3 Technical
data) is not exceeded.
Where applicable, also take into account external energy sources (such as
radiated heat sources) that could additionally heat the medium.
In case of doubt, contact KNF Customer Service.

Fig.5 Function principle of double diaphragm pump
Double diaphragm pumps transfer, compress (depending on the version) and
evacuate gases and vapors.
The elastic working diaphragm (4) is moved up and down by the eccentric (8)
and the connecting rod (9). In the downwards stroke, it aspirates the gas to be
transferred via the inlet valve (2). In the upwards stroke, the working di-
aphragm presses the medium out of the pump head via the outlet valve (1).
The transfer chamber (3) is separated from the pump drive by the working di-
aphragm.
Located below the working diaphragm is a second diaphragm (safety di-
aphragm (7)), which is under less mechanical stress during pump operation.
Should the working diaphragm be damaged, no gas can escape from the
pump.
The closed innerspace (5) between the two diaphragms can be monitored for
pressure change with the help of the hole(s) (6) provided for this purpose.
Damage to the working diaphragm and safety diaphragm can thereby be de-
tected immediately.
