Protect the device, especially the gas inlets and tubes, against dust, falling parts
and external impact.
P2.2 Atex
If sample gas pump P2.2 Atex is installed on a mounting plate, only use the included brackets and
rubber­metal buffers. Operation without rubber­metal buffers is forbidden. Use these buffers as well
if the pump is installed on an existing substructure. Please refer to the attached data sheets for the
hole pattern.
P2.4 Atex
Please refer to drawing 42/011­Z01­03­3 for mounting sample gas pump P2.4 Atex. Before mount­
ing the sample gas pump check that the pump is complete. In addition, 6 screws and nuts M6 with

4.3.1 Conversion to pump body pointing down
CAUTION
Damage to the device
Especially with pump head pointing down, make sure that no dust or small parts
can intrude the pump through the ventilations slot. Nevertheless, the slot must
not be covered directly. If this is not possible, the pump must not be mounted with
pump head pointing downward.
To do this, unscrew the three cross­head screws of the housing cover and remove the cover (see
fig. 3, fig. 4) (see components drawing in the appendix). The crankshaft and the motor flange are
now visible. The pump housing is fixed with four hexagon head screws (wrench size 8) to the motor
flange (or connection flange for P2.4 Atex types). Remove them completely (fig. 5). Hold the hous­
ing when screwing out the last screw. Now turn the housing carefully by 180° on the flange center­
ing, re­fix it with the screws (fig. 6, fig. 7) and re­mount the cover (tightening torque of the hexagon
head screws 3 Nm). mounting the pump head with angle 45° is forbidden!

4.4 Connecting the gas tubes
The pumps are delivered with customized gas connections. Please compare the part­no. on the
type plate with the part­no. explained in chapter "Introduction".
Avoid mixed installations, that is connecting metal tubes to plastic bodies. If this is unavoidable for
sporadic applications, screw the metal fitting with utmost care and without any use of force to the
PTFE pump body.
Install the tubes in a way that the line at the inlet and outlet is flexible over a sufficient distance
(pump vibrates).
The pumps are marked with “In” for inlet (input) and “Out” for outlet (output). Make sure that the
connections to the tubes are tight.
If there is a crack to the bellow ambient air is sucked in and the pump still generates pressure.
For this reason, the pump must be monitored.
Therefore, install a suitable shut­off device and a suitable vacuum pressure gauge upstream the
sample gas inlet. If during operation and closing the suction line no under­pressure is generated,
the bellow is defective.
During normal operation, the bellow may be monitored by installing a flow controller upstream the
gas inlet and downstream the gas outlet.
A crack in the bellow can usually be detected in the following way:
Sudden drop down of the mass flow upstream the pump and constant flow or sudden increase of
mass flow downstream of the pump (pump may suck ambient air in through the crack!)
If your application includes a continuous monitoring of sample gas components (e. g. monitoring O2
concentration), a cracked bellow may be detected by a sudden and large change of the measured
value (mixing the sample gas with ambient air).
NOTICE
If flammable gases (even above upper explosion limit (UEL)) or toxic gases are
supplied, continuous monitoring of the pump is mandatory.

DANGER
Explosion hazard, Risk of poisoning!
If combustible or toxic gases are delivered and the bellow cracks, explosive or
toxic gas mixtures may form or leak.
Monitor the pump. If any defect occurs at the pump shut off the pump immedi­
ately.
If flammable gases above upper explosive limit (UEL) are supplied, we recommend in addition
monitoring the lower explosive limit (UEL) at the installation site.
If toxic gases are delivered, we recommend in addition monitoring the occupational exposure limit
(OEL) at the installation site.
CAUTION Don't let the pump work for a longer time if the suction line is shut­off.
Furthermore, the mass flow has to be monitored with suitable manometer and flow meter and the
pump must be protected with a suitable flame arrestor.

Operation and control
CAUTION
Wrong mains voltage
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
According to the certification, a switch or power switch must be installed for the motor. It must be
easily accessible by the user. The switch must be marked as circuit breaker for the device. It must
not be installed in the mains power cord and must not interrupt the protective earth conductor. Fur­
thermore, it must disconnect the device from all poles.
The device must be operated with the factory­installed motor. The operator must not replace the
device or the motor with a different model.
The sample gas pump must be protected against overheating by a suitable overload protection
(motor protection switch according to the certification).
Regard rated current and settings of the motor protection switch (see type plate of the motor).
In contrast to protection class "Ex nA II", failure mode is monitored in protection class "increased
protection". Therefore, the motor protection switch must switch off within the specified time tE for
the respective temperature class if the motor is blocked. The requirement will be satisfied if the trip­
ping time (it can be picked from the tripping characteristics (initial temperature 20 °C) for the ratio
IA/IN) is lower than the specified time tE. (See data sheet 03 and 04 and CE­Type Examination
Certificate PTB 02 ATEX 3147.)
Connect the pump according to the circuit diagram inside the terminal cover plate and provide suffi­
cient strain relief of the mains cable. Make sure that mains voltage and frequency meet the spe­
cifications of the motor (voltage tolerance ± 5 % and frequency tolerance ± 2 % based on 220­240
V respectively 110­120 V).
Select mains and PE cross section according to the rated current.
The cross section must be at least 1.5 mm2.
Connect the protective earth conductor of the motor to the local earth conductor.
Connect the mounting plate of the pump with means of the press­fitted PE bolt to the local earth
conductor. As an alternative, it is allowed to connect the PE bolt at the mounting plate to the ex­
ternal PE bolt with a cable.
Stray electric currents may not flow through this connection.
It is essential to connect the protective earth conductor to the marked PE terminal. Regard national
directives, in Germany DIN VDE 0100.
Make sure that no foreign bodies, dirt and moisture are left inside the terminal box. Seal non­used
cable ducts and the dermal box itself against dirt and water. Use the original gasket when closing
the terminal box.
Seal non­used holes with ATEX­approved plugs.
Obey differing specifications on the type plate. The conditions at the installation site must meet all
specifications on the type plate.

– the electrical connections are fixed tightly and that monitoring devices are installed and set ac­
cording to directions!
– air vents and cooling surfaces are clean.
– protection measures are installed; Grounding!
– the motor is fixed properly.
– the terminal box is closed and the cable ducts are sealed properly.
– the elastomer gear ring of the coupling (P2.4 Atex only) is installed correctly and is not dam­
aged.
– the necessary protection and monitoring devices (according to the application) are installed and
ready for operation (depending on the pump type, e. g. motor protection switch, manometer,
flame arrester, temperature monitoring).
When switching the sample gas pump on make sure that
– no abnormal sounds or vibrations occur.
– the flow rate is neither too low nor too high. This would indicate a cracked bellow.
5.2 Operating the sample gas pump
The sample gas pump is suitable for delivering gases only. It is not suitable for liquids.
The sample gas pump should be operated without pressure. A system pressure above 0.5 bar is
not allowed. The gas outlet must not be closed. The minimum flow rate must be 50 l/h. If a throttle
of a gas pump is under 150 l/h in continuous operation, the flow rate must be adjusted by a bypass
valve. In this case, pump type "PTFE with bypass valve“ should be used.
NOTICE
Extreme throttling reduces the life time of the bellow.
If the pump is equipped with a bypass valve, the flow rate can be adjusted. Do not apply force
when turning the valve, because the valve may be damaged otherwise! The turning range of the
valve is about 7 turns.
NOTE: Read and regard the maintenance plan!
6 Maintenance
The device must only be maintained in non­hazardous areas and only if the device has cooled
down. In particular, any cleaning of the device with pressurized air must be carried out in non­Ex
areas only.
– Maintenance of the device shall be performed by trained staff only, familiar with the safety re­
quirements and risks.
– Only perform maintenance work described in this manual.
– Regard all relevant safety regulations and internal operating instructions during maintenance.

Maintenance
DANGER
Use appropriate tools
According to DIN EN 1127­1, the operator is responsible to select and use appro­
priate tools.
Application in explosive atmosphere
Combustible gases and dust may inflame or explode. Avoid the following hazard­
ous situations:
Electrostatic charge (spark formation)
Clean plastic parts and labels with damp cloth only.
Spark formation
Protect the equipment against external impact.
Install a flame arrester in case of a flashback hazard.
Inflame of dust
If the device is used in dust ambiance, remove the layer from the components
regularly. Also remove the dust layer in areas difficult to access (see chapter
"Cleaning").
Conserve the protective effect of the coating
To avoid potential ignition hazard, the protective effect of the coating must not be
derogated by abrasion or corrosive media and must be conserved in any case.
Refinishing or repainting is not allowed!
Do not use sharp or pointed tools.
CAUTION
Hot surface
Burning hazard
According to the product type and operation conditions, the temperature of the
housing may exceed 50 °C during operation.
Depending on the conditions at the installation site it may be necessary to
provide these areas with appropriate warning signs.
Depending on the quality of the processed sample gas it may be necessary to replace the inlet and
outlet valves from ime to time. The procedure is described in chapter Replacing the inlet and outlet
valves [_ 24].
If the valves are heavily contaminated, especially after a short time, consider installing a particle fil­
ter upstream the pump. This increases the service life significantly.
Depending on the operation conditions, maintenance intervalls for the follwing tasks must be
defined (see Maintenance schedule [_ 20])
– Check installation site and terminals for dirt and clean them if necessary.
– Check electrical connections for tight contact.
– Clean the cooling air channels of the motor.
– Check the flexible spider for damage and backlash.

6.2 Checking the below
DANGER
Explosion hazard, Risk of poisoning!
If combustible or toxic gases are delivered and the bellow cracks, explosive or
toxic gas mixtures may form or leak.
Monitor the pump. If any defect occurs at the pump shut off the pump immedi­
ately.
Since a crack in the bellow allows the ambient atmosphere to be sucked in and the sample gas
pump continues to generate pressure, the sample gas pump must be monitored.
20
BE420002
10/2013
Installation and Operation Instructions
Sample gas pumps P2.2­, P2.4­ATEX
Maintenance
This is done by connecting a suitable shut­off unit and a suitable vacuum pressure gauge ahead of
the sample gas input. For monitoring intervals also refer to bullet Maintenance schedule [_ 20]. If
during operation, after closing the suction line, no negative pressure is produced, the bellows is de­
fective.
In regular operation the bellow can also be monitored by integrating a flow meter control ahead of
the gas input and behind the gas output of the pump.
A tear in the bellows can typically be registered as follows:
Sudden reduction of the suction volume/flow volume before the pump with simultaneously consist­
ent or suddenly increased delivery volume after the pump (pump can convey ambient air suctioned
in due to the tear!).
If you providing continuous monitoring of sample gas components in your application (e.g. monitor­
ing the O2 content in the sample gas), the bellows tearing can possibly also be registered with a
sudden severe change in the data (sample gas and ambient air mixing).
NOTICE
If flammable gases (even above upper explosion limit (UEL)) or toxic gases are
supplied, continuous monitoring of the pump is mandatory.
NOTICE
If the bellow cracked, turn the pump off immediately!
When conveying flammable gasses above the upper explosive limit (UEL) we further recommend
monitoring the lower explosive limit (LEL) in the installation location.
When conveying toxic gasses we recommend MAC monitoring (MAC: maximal accepted concen­
tration) in the installation location.

Installation and Operation Instructions
Sample gas pumps P2.2­, P2.4­ATEX
Maintenance
The used coupling (type P2.4 Atex) is a backlash­free coupling!
Thus the backlash has to be inspected.
If there is a backlash, the coupling has to be replaced immediately independent of maintenance in­
tervals.
For this, the pump head side of the flange has to be separated from the rest by loosening the con­
necting screws M6.
Remove the worn spider and clean the coupling­ and intermediate flange from dust and other con­
tamination.
Mop up stuck dirt with a wet and clean cloth (do not use detergents containing organic solvents).
Mount the new spider to the hub at the motor's side. Reduce the friction by sightly greasing the
elastomer or the hub. For this, only use mineral oil­based oil or grease without any additives.
Now, remount the combination of pump head and intermediate flange to the coupling flange and fix
it with connecting screws M6. Correct mounting can be checked through the inspection hole in the
coupling flange.
Connect the pump as described in chapter Electrical connections [_ 14] and carry out a test run.
Fill in test values of maintenance on User book ﴾Please make copies﴿ [_ 31] of the pump.

Important note
The tables headed "Chemical resistance of plastics" and "Properties of plastics materials" have
been compiled from information from various producers of raw materials. The figures relate exclus­
ively to laboratory tests on raw materials. Plastics items made from these materials are often sub­
ject to influences which cannot be detected in a laboratory test (temperature, pressure, stresses in
the material, chemical substances, design features, etc.). For these reasons the figures quoted can
serve only as a guideline. In case of doubt we strongly recommend that a test be carried out. No
legal claims can be derived from these figures and we disclaim all liability. The chemical and mech­
anical resistance of a product does not suffice for the assessment of its suitability for use, for ex­
ample legislation on flammable liquids (explosion protection) is to be taken into particular consider­
ation.
Chemical resistance for other substance on request.

Hints for variations:
Position of pump head:
(P2.2 and P2.82 types only):
If the gas contains entrained liquids, the pump head must point downwards. Although the pump head may be turned by
the customer as described in the manual, we suggest ordering it in the required configuration.
Pump head material:
The standard material is PTFE. This can be equipped with a bypass valve to reach all the operation points in the grey
area in the flow curve of the pump head (P2.2 and P2.82 types only). Depending on the tubing requirements, a stainless
steel body may be ordered (bypass valve not available).
Valve material:
(P2.2 Atex and P2.82 Amex types only)
For standard non-heated applications with sample temperatures up to 100 °C (212 °F), the PTFE/PVDF valves are
sufficient. For higher temperatures, the valves for temperatures up to 140 °C (284 °F) are required. Please note that
maximum temperatures may be limited for certain temperature classes (see the tables on page 2).

Hints for variations:
Position of pump head:
(P2.2 and P2.82 types only):
If the gas contains entrained liquids, the pump head must point downwards. Although the pump head may be turned by
the customer as described in the manual, we suggest ordering it in the required configuration.
Pump head material:
The standard material is PTFE. This can be equipped with a bypass valve to reach all the operation points in the grey
area in the flow curve of the pump head (P2.2 and P2.82 types only). Depending on the tubing requirements, a stainless
steel body may be ordered (bypass valve not available).
Valve material:
(P2.2 Atex and P2.82 Amex types only)
For standard non-heated applications with sample temperatures up to 100 °C (212 °F), the PTFE/PVDF valves are
sufficient. For higher temperatures, the valves for temperatures up to 140 °C (285 °F) are required. Please note that
maximum temperatures may be limited for certain temperature classes (see the tables on page 2).

Device:
Single phase motors Type E.BY 63 … and U.BY 63 …
ID Marking:
Ex II 2 G Ex e IIT1 – T4 or
Ex II 2 D Ex tD A21 IP65 T120°C
Manufacturer: ATB Motorenwerke GmbH
Address:
G.-Bauknecht-Straße 1, 8724 Spielberg, Austria
Description of the supplements and modifications
The general constructive designs of the motors described in the test reports PTB Ex 9930114, PTB Ex 03-32320, PTB Ex 03-33211 and PTB 04-34294 are expanded as
follows:
The name of the manufacturer is changed to
ATB MOTORENWERKE GMBH
8724 Spielberg, Austria
The motor housings consist of stator housing and end plates. The stator housings are
manufactured from aluminium and the end plates are manufactured from aluminium or
gray cast iron. The rotor winding is manufactured in diecast aluminium. The shaft is
mounted in deep grooved ball bearings with lifetime lubrication.
Cooling takes place over the surface of the housing through the exchange of heat with
the ambient air through free convection (cooling method IC410 according to EN 600346) or by means of fans made from cast aluminium or plastic (cooling method IC411
according to EN 60034-6).
The electrical leads are connected via separately tested terminal boxes mounted on the
stator housing.
The degree of protection against the penetration of foreign matter, dust and water
(Ingress Protection Code IP) according to EN 60034-5 is IP 44. It can be increased up to
IP 65 through the use of radial shaft sealing rings on the shaft bushings and sealant on
the end plate centerings.
On motors for use in areas with combustible dust, the end plate shaft bushings are fitted
with radial shaft sealing rings.

2nd Supplement to the EC Type Examination Certificate PTB 02 ATEX 3147
The ambient- or coolant temperature range is -20 °C to 40 °C and this can be expanded
to -40 °C to 80 °C with suitable choice of the materials and components and under
consideration of the results of the thermal tests.
The influence of external sources of heat and cold is taken into consideration in the
choice of the materials and components, as well as for the thermal test of the respective
electrical design.
The windings can be equipped with PTC thermistors fitted in the overhangs for direct
temperature monitoring.
The motors can be equipped with a brake certified according to Directive 94/9/EC.
The motors can be fitted with a backstop.
On motors, whose windings are rated for the connection to single-phase supply systems,
capacitors certified according to Directive 94/9/EC can be mounted on the stator
housing.
The electrical data of the machine and data for the protection equipment for safe
operation, including the definitions for the observance of the temperature class or the
max. surface temperature, are set down in a data sheet to the EC type examination
certificate.
