Dear customer,
Your VACUUBRAND diaphragm pump shall support you at your work for a long time without any trouble
and with full load output. Thanks to our large practical experience we attained much information how you
could add to an efcient application and to personal safety. Please read these instructions for use prior
to the initial start-up of your pump.
VACUUBRAND diaphragm pumps are the result of many years of experience in construction and practical operation of these pumps combined with the latest results in material and manufacturing technology.
Our quality maxim is the ”zero fault principle”:
Every delivered diaphragm pump is tested extensively including an endurance run of 14 hours. Due to
this endurance run, also faults, which occur rarely, are reported an can be corrected. Every single dia-
phragm pump is tested on achievement of the specication after the endurance run.
Every VACUUBRAND pump leaving our factory achieves the specication. We feel obliged to
this high quality standard.
We are aware that the vacuum pump should not draw a part of the real work and we hope to contribute
with our products to an effective and trouble-free realisation of your work.
Yours
VACUUBRAND GMBH + CO KG

NOTICE
☞ Read and comply with this manual before installing or operating the equip-
ment.
☞ Transport the pump at the provided handle.
Remove all packing material, remove the product from its packing-box, remove the
protective covers from the inlet and outlet ports and keep, inspect the equipment.
If the equipment is damaged, notify the supplier and the carrier in writing within three
days; state the item number of the product together with the order number and the
supplier’s invoice number. Retain all packing material for inspection.
Do not use the equipment if it is damaged.
If the equipment is not used immediately, replace the protective covers. Store the
equipment in suitable conditions.
Intended use
☞ Use the equipment for the intended use only according to the ATEX conformity, e.
g. for pumping gas atmosphere without aerosol in a range form 0.1 to 1000 mbar
and a maximum inlet pressure (dynamic pressure) and outlet pressure of 1100
mbar (absolute).
☞ The pump and all system parts must not be used on humans or animals.
☞ Prevent any part of the human body from coming into contact with vacuum.
☞ Ensure that the individual components are only connected, combined and oper-
ated according to their design and as indicated in the instructions for use.
☞ Comply with notes on correct vacuum and electrical connections, see section
”Use and operation”.
NOTICE
The pumps are marked with ”X” (according to EN 13463-1), i. e. restrictions of
the operation conditions:
• The pumps are designated for a low degree of mechanical stress and have
to be installed in a way so that they can not be damaged from outside.
Pumping units with glass attachment parts have to be installed protected
against shocks from the outside and against glass splinters in the event of
breaking (implosion). Attention: The joint clips at the glass attachment parts
are not grounded. Avoid charge.
• The pumps are designated for an ambient and gas inlet temperature during
operation of +10 to +40°C. Never exceed these ambient and gas inlet temperatures.
Setting up and installing the equipment
Before system start-up of the pump or the complete system the user has to evaluate
in its entirety the explosion risks and takes adequate measures in application of the
principle of risk assessment.
Documents are only to be used and distributed completely and unchanged. It is strictly the users´ responsibility to check carefully
the validity of this document with respect to his product. manual-no.: 999290 / 12/12/2016
Page 13
page 13 of 68
The evaluation and the measures have to be laid down in an explosion protection
document before system start-up.
The pump/system must not be operated until operation without danger in explosive
atmosphere is ensured. Provide suitable control, protection and warning sys-
tems even in the event of failure.
The inner (pumped media) and outer part of the pump have to be evaluated
separately because of their different conformity (see also section ”Technical
data” and ”Notes regarding devices with ATEX conformity”).
The pumps are not suitable for pumping dust and have no approval for operation
below ground.
The pumps are not suitable for pumping self inammable substances, for substanc-
es which are inammable without air and explosive substances.
☞ Electrical and vacuum components might require a separate approval.
☞ Include the components in the recurrent tests of tightness for pressure vessels, in
the case of hits and beats an intermediate leak test is required.
☞ Due to the high compression ratio of the pumps, pressure at the outlet port might
be generated being higher than the max. permitted pressure compatible with the
mechanical stability of the system.
☞ Do not permit any uncontrolled pressurizing (e.g. make sure that the exhaust
pipeline cannot become blocked). Risk of bursting!
☞ Always provide a free and pressureless exhaust pipeline.
☞ If there is an exhaust isolation valve, make sure that you cannot operate the equip-
ment with the valve closed.
NOTICE
• Secure coolant hoses at the hose nozzles (e.g. with hose clip) to prevent their
accidental slipping.
• Comply with maximum permissible pressures at inlet and outlet and pressure
differences, see section ”Technical data”. Do not operate the pump with overpressure at the inlet.
• Attention: Flexible elements tend to shrink when evacuated.
Provide a rm level platform for the equipment and check that the system to be
evacuated is mechanically stable and that all ttings are secure. Ensure a stable po-
sition of the pump without any mechanical contact except of the pump feet. Comply
with all applicable safety regulations.
Pumping units with glass attachment parts have to be installed protected
against hits from outside and protected against splinters (against implosion).
Adopt suitable measures prior to the rst use.
Attention: The joint clips at the glass attachment parts are not grounded. Avoid
charge.
Obey all relevant requirements (regulations and guidelines) and adopt suitable
safety measures.
☞ Pay attention to the max. permitted ambient temperature and make sure
ventilation is adequate especially if pump is installed in a housing or if
ambient temperature is elevated, install an external automatic ventilation
system if necessary. If pumping hot process gases make sure that the maximum permitted gas inlet temperature is not exceeded.
☞ If the equipment is brought from cold environment into a room for operation,
allow the equipment to warm up (pay attention to water condensation on cold
surfaces).
☞ The work clothing of the user must not lead to electrostatic discharge which may
ignite the explosive atmosphere.

Inlet
☞ Connection lines at the pump inlet have to be performed conductive grounded
and gas tight (designation of the pump connections see gures).
☞ The diameter of the inlet pipeline should be at the least as large as the diameter
of the pump connection pipelines.
☞ Obey max. inlet pressure (see ”Technical data”).
Outlet
☞ Connection lines at the pump outlet (small ange) have to be performed conduc-
tive grounded and gas tight (designation of the pump connections see gures).
☞ The diameter of the inlet pipeline should be at the least as large as the diameter
of the pump connection pipelines.
☞ Obey max. inlet pressure (see ”Technical data”).
☞ Lead away exhaust gas or condensate at the outlet of the pump and the overpres-
sure safety valve under consideration of all applicable safety measures. Avoid
backow of gases or condensate denitely.
☞ Escaped and/or intentional or unintentional released inammable gases or va-
pours which may lead to danger of explosion have to be lead away safely or lead
to an appropriate place. If not possible enclose the gasses, vapours or mist safely
or dispose in an other way. In case of mixtures or different gases the measures
must consider the highest risk.
Check the overpressure safety valve at the outlet regularly.
☞ Attention: If the exhaust pipeline is blocked the pumped gases may escape
into the environment through the overpressure safety valve. If necessary
take appropriate measures.
If pumping dangerous gases install a second completely independent exhaust
pipeline instead of the overpressure safety valve. If necessary assemble a hose
nozzle instead of the overpressure safety valve to lead away the gases through
a second exhaust pipeline. Attention: Never combine the exhaust pipelines, i. e.
provide a sperate line for each exhaust.
Inlet and outlet of the pump
☞ To avoid damage of the pump due ignition of gases or gas mixtures before or
behind the pump the user has to provide suitable safety devices against in-
coming of ames according to EN 12874. The user must ensure the suitability
concerning gas ow, chemical resistance and safeness against clogging prior to
use.
Inert gas purge
☞ The user must take suitable precautions to prevent any formation of explosive
mixtures in the expansion chamber using inert gas to purge the housing. Otherwise in case of a diaphragm crack, mechanically generated sparks, hot surfaces
or static electricity may ignite these mixtures.
☞ Inert gas connection lines (inlet and outlet) have to be performed conductive
grounded and gas tight (designation of the pump connections see gures).
☞ Connect the inert gas connections at the crankcase not serial but parallel.
☞ We recommend an inert gas purge of ≥ 1 l per minute.
☞ Provide an external pressure limitation to a pressure of 1.1 bar absolute if inert
gas is connected to the pump or at an air admittance valve. The inert gas has
to be dry and pure. It could be recommendable to provide an appropriate control
system to supervise the inert gas ow which switches off the pump in case of
failure (e. g. absence of inert gas) if necessary.
☞ To control the faultless function of the diaphragm it could be recommendable in-
stall a gas specic detector at the outlet of the inert gas purge. A signal from
the detector indicates a diaphragm crack. Switch off the pump immediately and
check diaphragms.

page 15 of 68
☞ It is possible to leave out the inert gas purge if the surrounding of the pump
is zone 2 or not an explosive atmosphere.
☞ Without inert gas purge the pump outer part has the specication II 3G IIB
T4 X.
Gas ballast
☞ Use only inert gas for gas ballast.
☞ We recommend the use of gas ballast when pumping condensable media.
☞ Gas ballast connection lines (inlet and outlet) have to be performed conductive
grounded and gas tight (designation of the pump connections see gures).
☞ Connect the inert gas connections at the gas ballast and the crankcase not se-
rial but parallel.
☞ Provide an external pressure limitation to a pressure of 1.1 bar absolute if inert
gas is connected to the pump or at an air admittance valve. The inert gas has to
be dry and pure. It could be recommendable to provide an appropriate control
system to supervise the inert gas ow which switches off the pump in case of
failure (e. g. absence of inert gas) if necessary.
Pumping at high inlet pressure may lead to overpressure at the gas ballast valve.
☞ Pumped gases or condensate might be pushed out in case the valve is open.
☞ The inert gas lines have to be chemical resistent due to possible backow.
Electrical connection
☞ Electrical connection of the pump must be performed only by a suitable trained
and supervised personnel.
☞ The motor cable for pumps in 230V version contains wires colour coded as fol-
lows: green or green and yellow: earth; blue or white: neutral; brown or black:
live.
☞ Provide a fuse for the mains cable (L and N) according to the current draw of the
motor, see ”Technical data”. When using pumps with two motors provide a fuse
for each pump motor separately. Due to a high charge current for each motor a
protection is recommended, e. g., automatic fuse 16A type C.
☞ The earth connection of the device (potential equalization) has to be performed
only using the green or green/yellow earth connection wire. Connect the earth
connection wire of the device to the earth connection of the power supply line and
the potential equalization point of the environment of the device.
☞ When using pumps with two motors absolutely connect both motors as de-
scribed above. Ensure that always both motors are running.
Connection of the control cable
☞ Electrical connection of the pump must be performed only by a suitable trained
and supervised personnel.
In case of pumps with two motors (MV 10C EX VARIO) connect the control cables
in series.
Maximum voltage: 12 V.
Maximum current: 60 mA.
Comply with polarity!
The control cable of the pump contains four colored wires:
brown (+): 4 - 20 mA / speed control
blue (-): 4 - 20 mA / speed control
black: Status
grey: Status

page 16 of 68
Attention: Never use the antistatic connection at the housing of the device to
connect the device to ground, use only the green or green and yellow connection
wire of the motor. Use the antistatic connection at the housing only to perform an
antistatic connection of other non-electronic devices and components, e. g. inlet
and outlet vacuum hoses or something similar. Never lead away short-circuit currents using this connection. External electric devices have to be connected at the
potential equalization point of the environment separately and independent of this
device.
☞ Equipment must be connected only to a suitable fused and protected electrical
supply and a suitable earth point by suitable trained personnel. Failure to connect
the motor to ground may result in deadly electrical shock.
☞ Check that mains voltage and current conform with the equipment (see rating
plate).
☞ Obey notes regarding the motor in section ”Instructions manual: Motor
with integrated speed control”, see below.
The motor and the motor circuit board are protected by a thermal protection with
automatic reset.
Attention: The pump might restart on its own after sufcient cooling. Take appropri-
ate precautions, if an automatic restart of the pump may lead to a dangerous situation.
☞ Avoid reliable high heat supply (e. g. due to hot process gases). Maximum per-
mitted gas and ambient temperature se ”Technical data”.
☞ Make sure ventilation is adequate especially if pump is installed in a housing or if
ambient temperature is elevated, install an external automatic ventilation system
if necessary.
☞ Ensure that in case of pumps with two motors both motors are switched on at
the same time, if not possible switch on the motor of the pump at the outlet rst.
Ambient conditions
To the best of our knowledge the equipment is in compliance with the requirements
of the applicable EC-directives and harmonized standards (see ”Declaration of conformity”) with regard to design, type and model, especially directive EN 61010-1.
This directive gives in detail conditions, under which the equipment can be operated
safely (see also IP degree of protection).
Adopt suitable measures in case of differences, e. g. using the equipment outdoors,
installation in altitudes of more than 1000 m above mean sea level, conductive pollution or dewiness.
Pay attention to the permissible maximum ambient and gas inlet temperatures
(see ”Technical data”).
Operating conditions
The pumps have a conformity according to their specication to be installed in
areas and to pump out of areas which contain under normal operation conditions
occasionally a potential explosive atmosphere as a mixture of air with inammable
gases or vapours (category 2). Class of ignition and temperature see ”Technical
data”.

page 17 of 68
The specication for category 2 for the outer part of the pump is only valid when purging the crankcase with inert gas. Without inert gas purging the
pump has the specication II 3G IIB T4 X for the outer part.
☞ Adopt suitable measures to prevent the release of dangerous, explosive, corro-
sive or polluting uids.
☞ If pumping different substances, it is recommended to purge the pump with air
or inert gas prior to changing the pumped media in order to pump out residues
and to avoid reactions of the pumped substances with each other and with the
pump materials.
Take into consideration interactions and chemical reactions of the pumped
media.
☞ Ensure that the materials of the wetted parts are compatible with the pumped
substances, see section ”Technical data”.
☞ The valves and the diaphragms are wear parts. Replace the diaphragms and
valves at the latest at 90% of the typical lifetime or immediately at higher
noise level. The typical lifetime of a diaphragm is 15000 operation hours when
pumping non-corrosive or non-condensable gases, if necessary provide an operation time counter.
☞ Check the overpressure safety valve between the pump stages (only pumps
with four cylinders) regularly and replace at the latest at 90% of the typical life-
time (typical lifetime: 15000 operation hours).
☞ Take adequate precautions to protect people from the effects of dangerous sub-
stances (chemicals, thermal decomposition products of uoroelastomers), wear
appropriate safety-clothing and safety glasses.
☞ Obey applicable regulations when disposing of chemicals. Take into considera-
tion that chemicals may be polluted.
☞ Adopt suitable measures to prevent contamination of the pumped substances or
the environment.
Electronic equipment is never 100% fail-safe. This may lead to an indenite status of
the equipment. Provide protective measures against malfunction and failure.
☞ Operating the pump, stand still of the pump or operating the air admittance valve
must not lead to a critical dangerous situation under any circumstances.
Ensure that in case of failure the pump and the vacuum system always will turn into
a safe status.
☞ In case of leaks in the manifold or diaphragm cracks pumped substances might
be released into the environment or into the pump housing. To reduce the risk of
leaks, ask for a diaphragm pump with additional safety diaphragm.
☞ Obey especially notes on operation and use and maintenance.
☞ Failure of the pump (e. g. by power failure) or connected components, parts of
the supply (e. g. coolant) or change of parameters (e. g. increase of pressure
in the coolant system) must not lead to a critical dangerous situation under any
circumstances.

Safety during operation
➨ In case install an appropriate collecting and disposal system and take protective
action for pump and environment.
➨ Potentially explosive mixtures at the outlet of the pump have to be drained ap-
propriately, sucked off or diluted with inert gas to non-explosive mixtures.
☞ Pay attention to the symbol ”hot surfaces” on the equipment. Adopt suitable
measures to prevent any danger arising from the formation of hot surfaces or
electric sparks. Provide a suitable protection against contact if necessary.
☞ Check liquid level in both catchpots regularly and drain condensate in time.
• Comply with applicable regulations when disposing of chemicals. Take into consideration that chemicals may be polluted.
Take adequate precautions to protect people from the effects of dangerous sub-
stances (chemicals, thermal decomposition products of uoroelastomers), wear
appropriate safety-clothing and safety glasses.
Use only genuine spare parts and accessories.
☞ Otherwise safety and performance of the equipment as well as the electromag-
netic compatibility of the equipment might be reduced.
☞ If not using genuine spare parts the ATEX conformity becomes invalid.
Do not start the pump if the pressure difference between inlet and outlet port exceeds 1.1 bar at maximum.
Prevent the backpressure of gases and the backow of condensates.
Never suck liquids or dust into the pump.
Ensure that in case of failure the pump and the vacuum system always will turn into
a safe status.
Provide appropriate protective measures (i.e. precautions which allow for the requirements of the respective application) even for the case of failure and malfunc-
tion.
Comply especially with notes on operation and use and maintenance.
Due to the residual leak rate of the equipment, there might be an exchange of gas,
albeit extremely slight, between the environment and the vacuum system.
Adopt suitable measures to prevent contamination of the pumped substances or the
environment.

Maintenance and repair
Wear parts have to be replaced regularly. In normal use, the lifetime of the diaphragms and valves is typically 15,000 operating hours. Bearings have a typical durability of 40000 h.
Use only genuine spare parts and accessories.
☞ Otherwise safety and performance of the equipment as well as the electromag-
netic compatibility of the equipment might be reduced.
☞ If not using genuine spare parts the ATEX conformity becomes invalid.
Ensure that maintenance is done only by suitable trained and supervised technicians.
➨ Isolate equipment from mains and wait two minutes before starting mainte-
nance to allow the capacitors to discharge.
• Before starting maintenance vent the pump, isolate the pump and other components from the vacuum system. Allow sufcient cooling of the pump. Drain con-
densate, if applicable.
☞ Ensure that the pump cannot be operated accidentally. Never operate the
pump if covers or other parts of the pump are disassembled. Never operate
a defective or damaged pump.
☞ Attention: The pump might be contaminated with process chemicals which have
been pumped during operation. Ensure that the pump is decontaminated before
maintenance and take adequate precautions to protect people from the effects of
dangerous substances if contamination has occurred.
☞ Take adequate precautions to protect people from the effects of dangerous sub-
stances (chemicals, thermal decomposition products of uoroelastomers), wear
appropriate safety-clothing and safety glasses.
☞ To avoid danger due to electrostatic ignition wipe the device or parts of the de-
vice only with a humid cloth.
In order to comply with law (occupational, health and safety regulations, safety at
work law and regulations for environmental protection) vacuum pumps, components
and measuring instruments returned to the manufacturer can be repaired only when
certain procedures (see section ”Repair - Maintenance - Return - Calibration”)
are followed.

Notes regarding devices with ATEX conformity
This information sheet does not replace the instructions for use!
In directive 89/391/EEC the European Union has dened requirements for safety at work, which later
have been detailed for explosive atmospheres in the directive 1999/92/EC.
The requirements to equipment for operation in explosive atmospheres have been dened in the directive 94/9/EC, since April 20th 2016 in directive 2014/34/EU (also known as ATEX 100a or ATEX 95).
Concerning technology these directives only state general requirements. Technical details and test procedures are “recommended“ in European standards (e.g. for equipment with ATEX conformity: EN 1127,
E50014ff, EN 60079, EN 13463ff.).
Since July 1st 2003 equipment intended for use in potentially explosive atmospheres shall only be sold
if the equipment is in accordance with directive 94/9/EG (ATEX), since April 20th 2016 in accordance
with directive 2014/34/EU. This applies only to new equipment. The repair of equipment sold prior to July
1st, 2003 is not affected. EX approvals according to directive 94/9/EC remain valid under 2014/34/EU.
Requirements to users and manufacturers of equipment according to ATEX:
The user of a system according to ATEX has to analyse the overall explosion risks according to
directive 1999/92/EC and has to take adequate measures by means of a risk assessment. The evaluation and validation of measures has to be documented in an explosion protection document, specifying
among other things the areas classied as potentially explosive (see below). The inner part of the pump
(pumped gases) and the environment of the pump (outer explosion protection) have to be evaluated
separately. Often the requirements will be different.
The responsibility for the classication of areas with potentially explosive atmospheres into
zones and for the specication of requirements to the equipment (category of equipment, class
of ignition, temperature class etc.) is accountable strictly to the operator of the system.
The equipment used has to comply with these requirements. VACUUBRAND does not advise
customers concerning requirements to the equipment under the specic aspects of the cus-
tomer’s applications.
Equipment with ATEX-conformity is to be used by appropriately instructed personnel only.
ATEX marking, intended use:
The marking of the equipment corresponding with the standards (see above) gives the areas in which
the equipment may be used according to its intended use.
Technical data, safety notes and intended use:
See instructions for use!
The equipment must not be used if the instructions for use are not read, fully understood and
obeyed.
Clean, check and maintain equipment regularly.
Do never operate a defective equipment.
Documents are only to be used and distributed completely and unchanged. It is strictly the users´ responsibility to check carefully

Electrical connection:
VACUUBRAND diaphragm pumps with ATEX-conformity (device cat. 2) are equipped with a 230 V /
50 Hz single-phase motor and are protected by a thermal cutout with manual reset combined with an
overcurrent protection.
See instructions for use concerning notes on electrical connection.
Where applicable the motors can be connected directly to an appropriate power supply by suitably
trained and authorised personnel (electrician). It is the responsibility of the user to meet the requirements of explosion protection in the power supply and connection area.
For operation of VACUUBRAND ATEX VARIO pumps a motor speed control signal (4 – 20 mA) is required.
Vacuum and outlet connections:
See instructions for use: Make sure that all mechanical connections
are always gas tight and electrically conducting.
The exhaust pipeline must be designed in a way that it cannot become blocked.
If the exhaust pipeline becomes blocked, the overpressure safety device at the pump releases potentially dangerous gases into the environment. Take appropriate safety measures (see instructions for
use).
Evaluate the risk of explosion for the release of pumped gases at the outlet of the pump.
Use and connection of inert gas supply:
For external ATEX equipment category 2G (e.g. for use in Ex-zone 1) the crank case of the pump has
to be ushed with inert gas (e.g., nitrogen). A ow of approx. 1 l/min (at atmospheric pressure up to
max. 0.1 bar over pressure) is sufcient. If necessary the ow should be monitored using a ow meter.
Without inert gas purge the pump has external equipment category 3G. This means the pump has to be
used in this case only in a surrounding with Ex - zone 2 (or no Ex-zone).
It is recommended to install a gas detector (specic to the pumped gas) at the outlet of the inert gas tubing. The maximum permitted overpressure at the inert gas outlet is 0.1 bar (check the ow rate through
the gas detector!). A positive signal from the detector indicates a diaphragm failure. In this event switch
off the pump immediately and check the pump.
In the case of pumping condensable vapours, use gas ballast. Connect inert gas with
maximum overpressure of 0.1 bar to the gas ballast inlet (see instructions for use).
Inlet of air into the gas ballast must never lead to formation of an explosive mixture inside the
pump
or at the outlet of the pump!

Use and operation
Installing in a vacuum system
• All connection lines at the pump (e. g. inlet, outlet, gas ballast connection, inert
gas connection) have to be performed conductive grounded.
• Connect pump and all connected components to ground.
• Avoid contact of the pump with rusty metal parts, e. g. by positioning the pump
with sufcient distance to surrounding parts.
• The pump is designated for a low degree of mechanical stress. Protect the pump
from damage and beats. In case of damage switch off the pump immediately,
check leak rate if necessary.
• Connection lines at the pump inlet have to be gas tight. Particles and dust must
not be aspirated, the user has to provide appropriate lters if necessary. The user
must ensure their suitability concerning gas ow, chemical resistance and safe-
ness against clogging prior to use.
• Connect an exhaust line gas tight at the pump outlet if necessary. Always dispose
of exhaust gases appropriately (e.g. into a fume hood). If there is risk of release of
dangerous or polluting uids, install an appropriate system to catch and dispose
of those uids.
• Reduce the transmission of vibration and prevent mechanical load due to rigid pipelines. Insert elastic hoses or exible elements as couplings between the
pump and rigid pipes. Attention: Flexible elements tend to shrink when evacuated.
• Use of a suitable valve to isolate the pump from the vacuum system is recommended to allow the pump to warm up before pumping condensable vapours or
to clean the pump before it is switched off.
• The gas outlet must never be blocked. The exhaust line has always to be free
(pressureless) to ensure an unimpeded discharge of gas.
• Especially if the gas ballast valve is open, a power failure may cause accidental
ventilation of the pump. In case this constitutes a potential source of danger, take
appropriate safety measures.
• Make sure ventilation is adequate especially if the pump is installed in a housing
or if the ambient temperature is elevated. Provide external ventilation if neces-
sary. Keep a distance of minimum 20 cm between fan and ambient parts.

Avoid throttling losses by using connecting pipes with large diameter and by keeping
them as short as possible.
In case of perturbing exhaust noise connect an exhaust hose.
Install outlet pipelines always falling to avoid backow of condensate towards the
pump.
When assembling, ensure vacuum-tightness. After assembly, check the whole system for leaks.
Secure hose connections at the pump appropriately against accidental detaching.
Attach the pipelines of the coolant circuit to the respective hose nozzles (hose nozzles 6-8 mm, see image) at the vapour condenser. Check hose connections prior to
starting operation of the cooling system.
Secure coolant hoses at the hose nozzles (e.g. with hose clip) to prevent their accidental slipping.
Page 29
page 29 of 68
• Attention: Install hoses of the cooling system in a way to avoid ow / dropping of
condensed water onto the pumping unit (especially cables and electronic parts).
Connection of the mains cable
☞ Electrical connection of the pump must be performed only by a suitable trained
and supervised personnel.
When using pumps with two motors (MV 10C EX VARIO) connect mains cable
parallel.
The motor cable for pumps in 230V version contains wires colour coded as follows:
green or green and yellow: earth
blue or white: neutral (N)
brown or black: live (L)
☞ Provide a fuse for the mains cable (L and N) according to the current draw of the
motor, see ”Technical data”. When using pumps with two motors provide a fuse
for each pump motor separately. Due to a high charge current for each motor a
protection is recommended, e. g., automatic fuse 16A type C.
☞ The earth connection of the device (potential equalization) has to be performed
only using the green or green/yellow earth connection wire. Connect the earth
connection wire of the device to the earth connection of the power supply line and
the potential equalization point of the environment of the device.
Attention: Never use the antistatic connection at the housing of the device to
connect the device to ground, use only the green or green and yellow connection
wire of the motor. Use the antistatic connection at the housing only to perform an
antistatic connection of other non-electronic devices and components, e. g. inlet
and outlet vacuum hoses or something similar. Never lead away short-circuit currents using this connection. External electric devices have to be connected at the
potential equalization point of the environment separately and independent of this
device.
☞ In case of power failure unintentional venting of the system is possible. Adopt
suitable measures if this might lead to a dangerous situation.
Connection of the control cable
☞ Electrical connection of the pump must be performed only by a suitable trained
and supervised personnel.
In case of pumps with two motors (MV 10C EX VARIO) connect the control ca-
bles in series, load per motor < 200 Ω.
Maximum voltage: 12 V.
Maximum current: 60 mA.
Comply with polarity!
The control cable of the pump contains four colored wires:
brown (+): 4 - 20 mA / speed control
blue (-): 4 - 20 mA / speed control
0 - 4 mA: Motor stops
4 - 20 mA: Linear increase of the motor speed from 30 - 1500 rpm
20 mA: Maximum motor speed of 1500 rpm
black: Status of control electronics
grey: Status of control electronics
contact closed: ok
contact open: fault
Max. 250V, 2A
The motor and motor electronics are protected by a thermal protection with
automatic reset.
• Attention: The pump might restart on its own after sufcient cooling. Take appropriate precautions, if an automatic restart of the pump may lead to a dangerous
situation.

Inlet
☞ If there is a danger of deposits in the pump chamber (check inlet and outlet of
the pump) control the pump chamber regularly and clean if necessary.
Connection of the inert gas purge
☞ If the surrounding of the pump is not an explosive atmosphere it is possible to
leave out the inert gas purge.
Connection of the inert gas gas ballast
☞ When using air rather than inert gas, risk of signicant damage to equipment and/
or facilities, risk of personal injury or even loss of life exists due to the formation
of hazardous and/or explosive mixtures if air and pumped media react inside or
at the outlet of the pump.
Outlet of the pump
☞ Always connect an exhaust lines at the pump outlet (small ange or hose
nozzle 10 mm). Perform the outlet line conductive grounded and gas tight
(designation of the pump connections see gures). Always connect the exhaust
to a suitable treatment plant (e. g. hood).
Overpressure safety valve at the outlet of the pump
The overpressure safety valve at the outlet prevents reliable high pressures in the
system. Check overpressure safety valve regularly and replace if necessary.
Attention: Deposits and condensate may lead to increased temperature and
to excess of the max. permitted temperatures! Increased temperatures possibly
may lead to ignition of ammable mixtures inside the pump.
Use inert gas gas ballast if necessary and check pump regularly for deposits.
Install a gas washing bottle, condenser, lter, separator, etc. at the inlet of the
pump if necessary.
Pumps with two motors
☞ Ensure that in case of pumps with two motors both motors are switched on at the
same time, if not possible switch on the motor of the pump at the outlet rst.
☞ Connect the inert gas connections at the crankcase not serial but parallel.
Attention: Glass parts (asks and condensers) of pumping units (pumps
with AK (IK) and EK) have no protection against splinters (against implosion) or against leakage in case of mechanical damage or hits from outside.
The user must ensure an appropriate protection against splinters / implo-
sion or leakage prior to the rst use.

at the vapour condenser.
Page 32
page 32 of 68
Separation of condensate:
Attention: Due to electrostatics reasons the vapour condenser has no protec-
tive layer to avoid separation of condensed water! Risk of bursting!
The exhaust waste vapour condenser enables an efcient condensation of the
pumped vapours at the outlet.
☞ Next to 100% solvent recovery.
☞ Install hoses for cooling water at the inlet and outlet (hose nozzle 6-8 mm), se-
cure hose connections against gliding down.
• Maximum permissible coolant pressure at the vapour condenser: 6 bar (absolute). Backow always pressureless.
• Assemble an optional coolant valve only in the inlet line of the exhaust waste
vapor condenser.
• Comply with the maximum permissible coolant pressures of additional components in the coolant circuit (e.g coolant valve).
• Avoid overpressure in the coolant circuit (e.g. caused by blocked or squeezed
coolant hoses).
Permissible range of coolant temperature at the vapour condenser:
-15°C to +20°C
Check hose connections prior to starting operation of the cooling system.
Check coolant hoses regularly during operation.
Do not allow the catchpots to get overlled. Maximum liquid level approx. 80% to
avoid problems when removing the catchpots.
Check liquid level in both catchpots regularly and drain catchpots in time.
Removing the catchpots:
Catchpot / collecting ask at outlet:
Remove joint clip, remove catchpot and drain condensate.
Catchpot at inlet:
Admit air or inert gas (via pump inlet) to atmospheric pressure. Remove joint clip,
remove catchpot and drain condensate. Reassemble drained catchpots.
Important: Comply with regulations when disposing of solvents/condensates. Reuse if possible, purify if contaminated.
For condensable vapours (water vapour, solvents, ...):
☞ Do not pump vapour before pump has reached its operating temperature and
without inert gas gas ballast.
☞ Use inert gas at the gas ballast to avoid the formation of explosive mixtures.
☞ With gas ballast ultimate vacuum will be reduced
☞ Do not pump vapour before pump has reached its operating temperature
In case of low boiling solvents when the formation of condensate is unlikely, the use
of gas ballast might be unnecessary.
☞ Operating the pump without gas ballast increases the solvent recovery rates at
the vapour condenser.

Page 33
page 33 of 68
☞ The pumped gases at the outlet of the pump or at the exhaust waste vapour
condenser have to be drained under consideration of all applicable safety regulations.
The user has to check the possibility of an explosive atmosphere at the outlet of
the pump or the exhaust waste vapour condenser. Therefore for example calculate the solvent partial pressure at the present cooling water temperature at the
exhaust waste vapour condenser and compare with the explosion limits of the
pumped solvent. If there is an explosive mixture, drain the gas at the outlet in
antistatic lines according to the valid explosion protection guidelines.
During operation
• Maximum ambient temperature: 40 °C
• If the pump is installed in altitudes of more than 1000 m above mean sea level
check compatibility with applicable safety requirements, especially IEC 60034
(motor might overheat due to insufcient cooling).
• If the pump has been exposed to increased ambient temperature (> 40°C)
check the pump for damage and perform a leak test if necessary (integral
leak rate < 0.1 mbar*l/s).
The pump achieves its pumping speed, ultimate total vacuum and vapour pumping
rate only at operating temperature (after approx. 15 minutes).
☞ Prevent internal condensation, transfer of liquids or dust. The diaphragm and
valves will be damaged, if liquids are pumped in signicant amounts. Check the
pump regularly at the outside for pollution or deposits, clean the pump if necessary to avoid increase of the operation temperature of the pump.
NOTICE
Shutdown

Replacing diaphragms and valves
Maintenance of the pump must be performed only by a suitable trained and
NOTICE
supervised personnel.
All bearings are encapsulated and are lled with long-life lubricant and run under
normal operating conditions maintenance free. Replacement of the bearing must be
performed at the latest at 90% of the nominal lifetime of the bearing (nominal lifetime of the bearing: 40000 operation hours, if necessary provide an operation time
counter). If the noise level is enhanced switch off the pump immediately and inspect.
Replacement of the bearing must only performed at the factory. Never operate a
defective pump.
NOTICE
The valves and the diaphragms are wear parts. Replace the diaphragms at the latest at 90% of the typical lifetime or immediately at higher noise level. The typical
lifetime of a diaphragm is 15000 operation hours when pumping non-corrosive or
non-condensable gases, if necessary provide an operation time counter.
Pumping condensable media, operation at high temperature, great gas ow or
deposits reduce the lifetime of a diaphragm signicantly. Therefore check the dia-
phragm regularly for faultless condition.
☞ Prevent internal condensation, transfer of liquids or dust. The diaphragm and
valves will be damaged, if liquids are pumped in signicant amount.
NOTICE
To control the faultless function of the diaphragm install a gas specic detector at the
outlet of the inert gas ush. A signal from the detector indicates a diaphragm crack.
Switch off the pump immediately and check diaphragms.
If the rated ultimate vacuum is no longer achieved, the pump interior, the hose connections, the diaphragms and the valves must be cleaned and the diaphragms and
valves must be checked for cracks or other damage. Replace defective parts immediately.
NOTICE
Inspect the ttings of the pump regularly, the maximum permitted leak rate is 0.1
mbar l / s.
When replacing diaphragms and valves check the overpressure safety valve at the
outlet of the pump.
Remove possible deposits in the crank chamber of the pump when replacing diaphragms and valves.
If the pump is exposed to corrosive gases or gases and vapours which may form deposits (e. g. crystallisation) or deposits due to pumped particles, maintenance should
be carried out frequently (according to the experience of the user).
☞ Regular maintenance will improve the lifetime of the pump and also protect both
man and environment.
Before starting maintenance vent the system, isolate the pump and other components from the vacuum system and the electrical supply. Drain condensate if ap-
plicable, avoid the release of pollutants. Allow sufcient cooling of the pump. Before
starting maintenance, wait two minutes after isolating the equipment from mains to
allow the capacitors to discharge.
Never operate the pump if covers or other parts of the pump are disassembled. Ensure that the pump cannot be operated accidentally. Never operate a defective or
damaged pump.
Ensure that the maintenance technician is familiar with the safety procedures which
relate to the products processed by the pumping system.

Attention: The pump might be contaminated with the process chemicals that have
been pumped during operation. Ensure that the pump is decontaminated before
maintenance and take adequate precautions to protect people from the effects of
dangerous substances if contamination has occurred.
☞ Wear appropriate safety-clothing when you come in contact with contaminated
components.
NOTICE
NOTICE
☞ Please read section ”Replacing diaphragms and valves” com-
pletely before starting maintenance.
Partially the pictures show pumps in other versions. This doesn’t inuence re-
placing diaphragms and valves of the pump.
If not using genuine spare parts the ATEX conformity becomes invalid.
Attention: Open the pump only outside of explosive atmospheres and only by
suitably trained personnel.
Always replace both diaphragms of a pump head!
Always disassemble and assemble only one pump head before opening the
next pump head. The single parts of a pump head are measured in a way so to
avoid that the diaphragm clamping disc hits the head cover. Never mix parts
of different pump heads or add or leave out washers.
We recommend to replace all diaphragms and valves of a pump at the same
time.

Notes on assembling ttings
The threads of the ttings at the pump heads might be sealed with PTFE bond (width 10 mm or 5 mm,
thickness 0.1 mm).
If the ttings are turned or have been removed, use new PTFE bond when reassembling.
If not using new ttings clean the thread of the ttings from PTFE bond.
Wind the thread of the tting two times against the direction of turning in (anticlockwise) with PTFE
bond.
Tighten the PTFE bond rmly. Ensure that the PTFE bond ends ush with the ttings. Ensure that the
PTFE bond not covers the openings in the elbow ttings.
Screw in elbow ttings (clockwise) until only half of a thread course is visible. Do not overtighten. Avoid
canting of the thread.

4. Transporting, Installation, and Wiring
Do not drop or apply strong impact on the product. Doing so may result in damaged parts or malfunction.
Do not connect an AC power supply voltage to the control input/output terminals. Doing so might result in
damage to the product.
Take sufficient shielding measures when using the product in the locations, subject to static electricity or
strong magnetic fields. Not doing so may result in damage to the product.
Prior to installation, inspect the motor to detect signs of damage during transport. Never use or
install a damaged motor, but submit a claim to the supplier and/or the transport company.
Electric data of the motor, valid for the rated power, can be found on the nameplate.
It is the responsibility of the user to ensure that the motor nameplate voltage and frequency are the same as
the mains supply.
Connection to the mains supply should only be executed by a recognized professional, respecting local
demands and regulations.
The user must ensure that the diameter of the cable is adequate for the voltage and current involved. (See
nameplate data of motor)
The motor must be protected against overloads and short-circuits.
When installing the motor, always connect the earth (ground). Elnor recommends that you do not use earthleakage circuit breakers but take alternative measures. The frequency converter can cause a DC current
(mA range) in the PE conductor, which might result in a malfunction of the earth leakage circuit breaker.
Not connecting the earth can result in electricity buildup at the motor enclosure, which
poses risks to people touching the enclosure, and which can be a cause for sparks and
resulting explosion when the motor is used in potentially explosive atmospheres.
Free circulation of fresh air for cooling the motor must be guaranteed, and the cooling fins of the cover must
be in the vertical plane.
The motor can be subjected to a 50HZ AC high-voltage testing of max 1,5kV.
5. Precautions for Correct Use
During normal operation, this motor can have rotating parts as well as hot surfaces.
Removing covers or improper use of this motor may result in severe injury to persons or property.
The motor may not be opened in the presence of potentially explosive atmospheres, or when
energized.
Only qualified technicians may service or open the motor, after observing a cooling-down period to
let the motor temperature decrease to ambient temperature. Always observe local regulations in
this respect.

The motor may be equipped with an automatic reset thermal overload protection: Do not come
close to the machine when the motor has stopped while functioning because the motor may
abruptly start when stopped by an alarm.
6. Operation Stop Command
Provide a separate emergency stop switch because the STOP signal from the converter is valid only when
function settings are performed.
When checking a signal during the power supply and the voltage is erroneously applied
to the control input terminals, the motor may start abruptly. Take appropriate care before checking
a signal.
7. Product Disposal
Comply with the local ordinance and regulations when disposing of the product.
8. Designated use and applicable certificates
This product is certified for use in certain potentially explosive atmospheres only (see further). It is
