Use
2.1. Proper use
The pumps are exclusively intended for transferring gases and
vapors.
Owner's responsibility
Operating parameters and
conditions
Only install and operate the pumps under the operating parameters
and conditions described in Chapter 4, Technical data.
Only complete pumps may be taken into service.
Make sure that the installation location is dry and the pump is
protected against rain, splash, hose and drip water.
Requirements for
transferred medium
Before using a medium, check whether the medium can be transferred danger-free in the specific application case.
Before using a medium, check the compatibility of the materials of
the pump head, structured diaphragm and valves with the medium.
Only transfer gases which remain stable under the pressures and
temperatures occurring in the pump.
2.2. Improper use
The pumps may not be operated in an explosive atmosphere.
The pumps are not suitable for transferring dusts.
The pumps are not suitable for transferring liquids.
Pumps designed to create either a vacuum or an overpressure
must not be used for these two purposes simultaneously.

Safety
Note the safety precautions in sections 6. Installation and
connection, and 7. Operation.
The pumps are built according to the generally recognized rules of
technology and in accordance with the occupational safety and
accident prevention regulations. Nevertheless, dangers can result
during their use which lead to injuries to the user or others, or to
damage to the pump or other property.
Only use the pumps when they are in a good technical and proper
working order, in accordance with their intended use, observing the
safety advice within the Operating and Installation Instructions, at
all times.
Personnel
Make sure that only trained and instructed personnel or specially
trained personnel work on the pumps. This especially applies to
assembly, connection and servicing work.
Make sure that the personnel has read and understood the Operating and Installation Instructions, and in particular the "Safety"
chapter.
Working in a safetyconscious manner
Observe the accident prevention and safety regulations when
performing any work on the pump and during operation.
The pump heads heat up during operation – avoid contact with them.
Handling dangerous media
Handling combustible media
When transferring dangerous media, observe the safety regulations when handling these media.
Be aware that the pumps are not designed to be explosion-proof.
Make sure the temperature of the medium is always sufficiently
below the ignition temperature of the medium, to avoid ignition or
explosion. This also applies for unusual operational situations.
Note that the temperature of the medium increases when the pump
compresses the medium (compressor operation).
Hence, make sure the temperature of the medium is 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 the technical specifications (chapter 4).
If necessary, consider any external sources of energy, such as
radiation, that may add heat to the medium.
In case of doubt, consult the KNF customer service.
4
Environmental protection
Store all replacement parts in a protected manner and dispose of
them properly in accordance with the applicable environmental
protection regulations. Observe the respective national and international regulations. This especially applies to parts contaminated
with toxic substances.

WARNING
Monitor pressure during operation.
If the pressure exceeds the maximum permissible operating pressure, immediately shut down
pump and eliminate fault (see chapter 9. Troubleshooting).
Only throttle or regulate the air or gas quantity in
the suction line to prevent the maximum permissible operating pressure from being exceeded.
If the air or gas quantity in the pressure line is
throttled or regulated, make sure that the maximum permissible operating pressure of the
pump is not exceeded.
Excessive pressure (with all of the related hazards) can be
prevented by placing a bypass line with a pressure-relief valve
between the pressure and suctions sides of the pump. For
further information, contact our technical adviser.
Pump standstill
With the pump at a standstill, open pressure and suction lines
to normal atmospheric pressure.
For pumps with thermal-switch:
Automatic starting can cause personal injury and
pump damage
When the operation of the pump is interrupted by the
WARNING thermal switch, the pump will restart automatically
after cooling down.
Take all necessary care to prevent this leading
to a dangerous situation.

Operation
Diaphragm Pump N 145 E
Switching pump on
The pump may not start up against pressure or vacuum during
switch-on. This also applies in operation following a brief power
failure.
Make sure that no pressure or vacuum is present in the lines
during switch-on.
Switching off the pump
KNF recommends: When transferring aggressive media, flush
the pump prior to switch-off to increase the service life of the
diaphragm (see section 8.2.1).
Open pressure and suction lines to normal atmospheric pressure.
