Safety
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 leads 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 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 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.
Do not expose any part of your body to the vacuum.
Open housing parts with notice sticker (see fig. 1) only after
separating mains plug from power source.
Fig. 1: Notice sticker
Handling dangerous media
When transferring dangerous media, be sure to observe the safety
regulations when handling these media.
Handling flammable 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.
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 (see section 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.
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.

The pump transfers, compresses (depending on pump version)
and evacuates gases and vapors.
The elastic diaphragm (4) is moved up and down by the eccentric
(5) and the connecting rod (6). In the downward stroke it aspirates
the gas to be transferred via the inlet valve (2). In the upward
stroke, the diaphragm presses the medium out of the pump head
via the outlet valve (1). The transfer chamber (3) is hermetically
separated from the pump drive (7) by the diaphragm.

Operation
7.1. Preparing for Start-up
Before switching on the pump, observe the following points:
Pump
Operational requirements
All hoses attached properly
Fan openings not blocked
Specifications of the power supply correspond with the
data on the pump’s type plate.
The pump outlet is not closed or constricted.
Tab. 9
7.2. Starting
Only operate the pump under the operating parameters and conditions described in chapter 4, Technical data.
Make sure the pump is used properly (see section 2.1).
Make sure the pump is not used improperly (see section 2.2).
Observe the safety precautions (see chapter 3).
Hazard of the pump head bursting due to excessive
pressure increase
Do not exceed max. permissible operating pressure
WARNING (see section 4).
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 suction side of the pump. For further
information, contact our technical adviser.
Pump standstill
12
With the pump at a standstill, open pressure and suction lines to
normal atmospheric pressure.
Diaphragm Vacuum Pump UN035_P
Operation
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.
After triggering of the thermal protection or in the
event of power failure, remove the pump’s mains
plug from the socket so that the pump cannot start
uncontrollably.
Attempt work on the pump only if the pump is
separated from mains power.
7.3. Switching pump on and off
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. If a pump starts against pressure, it may block. This
activates the thermal switch, and the pump switches off.
Make sure that no pressure or vacuum is present in the lines
during switch-on.
Switch on pump with mains switch (see fig. 2, 3 or 4, position 3).
Switching off the pump/removing from operation
When transferring aggressive media, flush the pump prior to
switch-off to increase the service life of the diaphragm (see section
8.2.1).
Switch off pump with mains switch (see fig. 2, 3 or 4, position 3).
Open pressure and suction lines to normal atmospheric pressure.
