1. About this document
1.1. Using the Operating Instructions
The Operating Instructions are part of the pump/system.
Carefully study the Operating Instructions before using a pump
or system.
Always keep the Operating Instructions handy in the work
area.
Pass on the Operating Instructions to the next owner.
Customer-specific project systems or pumps (systems and pump
models which begin with “PJ” or “PM”) may differ from the Operat-
ing Instructions.
For project systems and pumps, also observe the agreed upon
specifications.
1.2. Symbols and Markings
Warning
WARNING
A danger warning is located here.
Possible consequences of a failure to observe the
warning are specified here. The signal word, e.g.
Warning, indicates the danger level.
Measures for avoiding the danger and its conse-
quences are specified here.

LABOPORT Pumps and Systems Use
Translation of original Operating Instructions, english, KNF 121211-121345 01/10 5
2. Use
2.1. Proper Use
The pump/system is exclusively intended for transferring gases
and vapors.
Owner's responsibility
Only install and operate the pump/system under the operating
parameters and conditions described in chapter 5, Technical data.
Make sure that the installation location is dry and the pump/system
is protected against rain, splash, hose and drip water.
Before using a medium, check the compatibility of the materials of
the pump head, diaphragm and valves with the medium.
Before using a medium, check whether the medium can be trans-
ferred danger-free in the specific application case.
Only transfer gases which remain stable under the pressures and
temperatures occurring in the pump.
The high performance condenser must be installed on the outlet
side of the pump; if it is installed on the inlet side there is a danger
of implosion.
Observe the correct usage of the gas- and cooling liquid-
connections on the high performance condenser. Inlet and outlet
connections for the gas are not interchangeable.
Laboratory equipment or additional components connected to a
pump/system have to be suitable for use with the pneumatic capa-
bilities of the pump (see chapter 5.1, page 10).
2.2. Improper Use
The pump/system may not be operated in an explosive atmos-
phere.
The pump/system is not suitable for transferring dusts.
The pump/system is not suitable for transferring liquids.
For LABOPORT systems with vacuum controller: The vacuum
system must not be used if the entry of air or gas into the vacuum
system during venting (pump vent valve) could result in the crea-
tion of reactive, explosive or otherwise hazardous mixtures (e.g.
with the medium).
The pump/the system must not be used to create vacuum and
overpressure simultaneously.
An overpressure must not be applied to the suction side of the
pump/ the system.

3. Safety
Note the safety precautions in chapters 7. Installation, mount-
ing and connection, and 8. Operation.
The pump/system is 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/system or other property.
Only use the pump/system when it is in a good technical and
proper working order, in accordance with its intended use, observ-
ing the safety advice within the operating instructions, at all times.
Make sure that only trained and instructed personnel or specially
trained personnel work on the pump/system. This especially ap-
plies to assembly, connection and servicing work.
Make sure that the personnel has read and understood the operat-
ing instructions, and in particular the "Safety" chapter.
Observe the accident prevention and safety regulations when
performing any work on the pump/system 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.
When transferring dangerous media, observe the safety regula-
tions when handling these media.
Be aware that the pump/system is 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 chapter 5.1, page 10).
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.
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 inter-
national regulations. This especially applies to parts contaminated
with toxic substances.

LABOPORT Pumps and Systems Safety
Translation of original Operating Instructions, english, KNF 121211-121345 01/10 7
The KNF LABOPORT®pumps conform to the safety regulations of
the EC Directive 2004/108/EC concerning Electromagnetic Com-
patibility and the EC Directive 2006/42/EC concerning Machinery.
The requirements of the following harmonised standards are
fulfilled:
DIN EN 61010-1
DIN EN 61326-1
DIN EN 61000-3-2/3
The pumps correspond to IEC 664:
the overvoltage category II
the pollution degree 2
Only have repairs to the pump/system carried out by the KNF
Customer Service responsible.
Only authorized personnel should open those parts of the housing
that contain live electrical parts.
Use only genuine parts from KNF for servicing work.

Diaphragm pumps transfer, compress (depending on pump ver-
sion) and evacuate 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.

Function
Condensable components in the gas can be separated on the
pressure side of the pump. On the suction side the separator
collects particular matter and droplets. This protects the pump from
contamination.
The separator is made of a specially treated glass and features
implosion protection.
