Intended use
☞ The pump and all system parts are not to be used on humans or animals.
☞ Prevent any part of the human body from coming in contact with the vacuum.
☞ Make sure that the individual components are only connected, combined and
operated 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”.
• The pumps are designed for ambient temperatures during operation between
+10°C and +40°C. Check the maximum temperatures if installing the pump in a
cabinet or a housing and make sure ventilation is adequate. Install an external
automatic ventilation system if necessary. If pumping hot process gases make
sure that the maximum permitted gas inlet temperature, which depends on sev-
eral parameters like inlet pressure or ambient temperature (see ”Technical data”),
is not exceeded.
• Particles and dust must not be aspirated.
NOTICE
Use the equipment for the intended use only, i.e. for generation of vacuum in ves-
sels designed for that purpose.
Setting up and installing the equipment
➨ Equipment must be connected only to a suitable fused and protected electri-
cal supply and a suitable earth point. Failure to connect the motor to ground may
result in deadly electrical shock.
The supply cable may be tted with a moulded European IEC plug or a plug suit-
able for your local electrical supply. If the plug has been removed or has to be
removed, the cable will contain wires colour coded as follows: green or green and
yellow: earth; blue or white: neutral; brown or black: live.
☞ Do not permit any uncontrolled pressurizing (e.g. make sure that the exhaust pipe-
line cannot become blocked). If you have an exhaust isolation valve, make sure that
you cannot operate the equipment with the valve closed. Risk of bursting!
☞ Provide always a free and pressureless exhaust pipeline.
• 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.

• Check that mains voltage and current conform with the equipment (see rating
plate).
• Change the setting of the voltage changeover switch (pump with dual-voltage
motor) only if the pump is separated from mains. Check that the voltage changeo-
ver switch is set correctly. Attention: If the pump is switched on with wrong voltage selection, the motor might be damaged!
• Due to the high compression ratio of the pumps, pressure at the outlet port might
be generated being higher than the maximum permissible pressure compatible
with the mechanical stability of the system.
• Avoid overpressure of more than 0.2 bar in case inert gas is connected.
• Connect pipes gas tight at inlet and outlet of the pump.
• Attention: Flexible elements tend to shrink when evacuated.
NOTICE
NOTICE
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.
Keep a distance of minimum 20 cm between fan and ambient parts (e.g. housing,
walls, ...). Check fan regularly for dust/dirt, clean if necessary to avoid a cutback of
ventilation.
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 diameter of the inlet and outlet pipeline should be at the least as large as the
diameter of the pump connection pipelines.
Comply with all applicable and relevant safety requirements (regulations and guide-
lines), implement the required actions and adopt suitable safety measures.
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. Directive IEC 1010 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 bedewing.
Pay attention to the permissible maximum ambient and gas inlet temperatures
(see ”Technical data”).
Operating conditions
➨ The pumps have no approval for operation in or for pumping of potentially
explosive atmospheres.
➨ The pumps are not suitable to pump
- unstable substances and substances which react explosively under
impact (mechanical stress) and/or when being exposed to elevated
temperatures without air.

- self inammable substances,
- substances which are inammable without air and
- explosive substances.
• The pumps are not suitable for pumping substances which may form deposits
inside the pump. Deposits and condensate in the pump may lead to increased
temperatures even to the point of excessing the maximum permitted temperatures!
• If there is a danger of deposits in the pump chamber (check inlet and outlet of the
pump), inspect the pump chambers regularly and clean if necessary.
• The pumps are not suitable for pumping dust and have no approval for opera-
tion below ground.
NOTICE
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”.
Safety during operation
➨ Adopt suitable measures to prevent the release of dangerous, toxic, explosive, cor-
rosive, noxious or polluting uids, vapours and gases. In case install an appropriate
collecting and disposal system and take protective action for pump and environment.
➨ Prevent any part of the human body from coming in contact with vacuum.
➨ The user must take suitable precautions to prevent any formation of explosive
mixtures in the expansion chamber or at the outlet. In case of e.g. a diaphragm
crack, mechanically generated sparks, hot surfaces or static electricity may ignite
these mixtures. Use inert gas for venting if necessary.
➨ 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.
☞ Ensure that the exhaust pipeline is always free and pressureless.
• 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 OEM spare parts and accessories. Otherwise safety and perform-
ance of the equipment as well as the electromagnetic compatibility of the equipment might be reduced. Possibly the CE mark or the cTÜVus mark become void
if not using OEM spare parts.
NOTICE
Do not start the pump if the pressure difference between inlet and outlet port exceeds 1.1 bar at maximum.

page 7 of 36
Prevent the backpressure of gases and the backow of condensates.
Never suck liquids or dust into the pump.
Provide appropriate protective measures (i.e precautions which allow for the requirements of the respective application) even for the case of failure and malfunction.
Failure of the pump (e.g. due to power failure) or of connected components, parts
of the supply or change of parameters must not lead to a critical dangerous situation under any circumstances. In case of diaphragm cracks or leaks in the manifold
pumped substances might be released into the environment or into the pump housing or motor. 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.
In case of overload the motor is shut down by a self-hold thermal cutout in the
winding.
Attention: Reset possible only manually. Switch off the pump or isolate the equipment from mains. Identify and eliminate the cause of failure. Wait approx. ve minutes before restarting the pump.
NOTICE
Attention: In case of supply voltage below 100V, the lock of the cutout might be
restricted and the pump might restart on its own after sufcient cooling down. Take
suitable precautions, if an automatic restart of the pump might lead to a critical dangerous situation.
The A-weighed emission sound pressure level of the pump does not exceed 70
dB(A). Measurement according to EN ISO 2151:2004 and EN ISO 3744:1995 with
standard silencer or exhaust tube at outlet.
Maintenance and repair
Wear parts have to be replaced regularly. In case of normal wear the lifetime of the
diaphragms and valves is > 10000 operating hours. Bearings have a typical durability
of 40000 h. Motor capacitors have a typical durability in the range of 10000 to 40000 h depending strongly on the operation conditions like ambient temperature, humidity or load.
• Check every capacitor regularly by measuring its capacity and estimating its operation time. Exchange old capacitors early enough to prevent a failure. If an
overaged motor capacitor fails it might get hot and even melt and may cause a
ame to form which could be dangerous for persons and equipment in the
vicinity. The capacitors have to be replaced by an electrician.
➨ Isolate equipment from mains and wait two minutes before starting mainte-
nance to allow the capacitors to discharge.
➨ Before starting maintenance, wait two minutes after isolating the equipment
from mains to allow the capacitors to discharge.
☞ 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.

• 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 maintenance is done only by suitably trained and supervised technicians. Ensure that the maintenance technician is familiar with the safety procedures
which relate to the products processed by the pumping system.
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 ”Notes on return to the factory”) are followed.
Additional safety information for diaphragm pump ME 4R NT
Intended use
☞ Comply with notes on how to connect the equipment correctly to vacuum and
pressure systems, see section ”Use and operation”.
NOTICE
Use the equipment for the intended use only, i.e. to generate vacuum or to compress gases in vessels designed for that purpose.
Setting up and installing the equipment
☞ When operating the pump as a pressure pump, ensure that the maximally
generated overpressure is compatible with the mechanical stability of the pressure vessel. Overpressure may be generated only in vessels which are designed
for that purpose. Risk of bursting!
Attention: Obey the maximally admissible pressure (4 bar absolute) at the out-
let. The pump has an overpressure safety relief device at the pressure adjust-
ment device at the outlet (opening pressure: 4 bar absolute). If necessary install
an additional overpressure safety relief device in the pressure system. Flexible
elements tend to expand when pressurised.
☞ Do not permit any uncontrolled pressurizing (e.g. make sure that the exhaust
pipeline cannot become blocked). Risk of bursting!
☞ Especially when using the pump as vacuum pump ensure a free and pressure-
less exhaust pipeline.
• Obey maximum permitted pressures at inlet and outlet and pressure differ-
ences between inlet and outlet, see section ”Technical data”. Do not start the
pump with overpressure at the inlet.

Use and operation
Installing in a vacuum system
• 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.
• The gas outlet must never be blocked. The exhaust line has always to be free
(pressureless) to ensure an unimpeded discharge of gas.
• A power failure may cause unintentional ventilation of the pump. In case this con-
stitutes a potential source of danger, take appropriate safety measures.
• Pump with dual-voltage motor: Check that the voltage changeover switch at
the terminal box is positioned correctly.
Attention: If the pump is switched on with wrong voltage selection, the motor
may be damaged!
Before starting the pump, check that the voltage changeover switch at the termi-
nal box is correctly positioned.
Change the selection at the voltage changeover switch only if the pump is
separated from mains.
Voltage changeover switch:
Use a screw driver to adjust the supply voltage on the voltage changeover
switch at the terminal box of the pump:
”115” corresponds to 90-126 V and
”230” corresponds to 180-253 V.
• Make sure ventilation is adequate especially if the pump is installed in a housing

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.
When assembling, ensure vacuum-tightness. After assembly, check the whole system for leaks.
Secure hose connections at the pump appropriately against unintentional detaching.
Notes prior to the use of the manometers (only ME 4R NT):
The manometers used are manometers with glycerin lling. The overpressure manometer indicates the overpressure relative to the atmospheric pressure at the place
of installation. The vacuum meter indicates the absolute pressure.
Install the pump in the room of operation.
Prior to use the reference chambers have to be ventilated.
Else, not ventilating the manometer may lead to a systematic measuring error.
Ventilate the manometer using the pressure compensation
valve. Close the valve after ventilation.

NOTICE
During operation
• Maximum ambient temperature: 40 °C
• Make sure ventilation is adequate especially if the pump is installed in a housing
or if the ambient temperature is elevated.
• Potentially dangerous gases or vapours at the outlet of the pump have to be
drained and disposed appropriately.
• Due to the high compression ratio of the pumps, the pressure at the outlet port
might get higher than the maximally permitted pressure compatible with the mechanical stability of the system. Ensure that the pump outlet is not blocked or
restricted.
ME 4R NT:
• Attention: Do not unscrew the dispensing screw completely! There are no stops
at the end of the threads!
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).
Do not start the pump if the pressure difference between inlet and outlet ports
exceeds max. 1.1 bar. Attempts to start the pump at higher difference may cause
blockade and damage of the motor.
Check compatibility with maximally permitted pressure at outlet and maximum
pressure difference between inlet and outlet ports.
ME 4R NT:
For continuous operation at inlet pressures above atmospheric pressure the inlet
pressure must not exceed the outlet pressure. The maximally permitted pressure
at the outlet is 4 bar absolute.
Operating the pump at high inlet pressure or pumping dusty gases for a long time
may cause clogging of the silencer. Check the silencer regularly and replace or install
a hose nozzle (order no. 639758) with clamping ring (order no. 639729) instead.

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 for external soiling and deposits, clean if necessary to
avoid an increase of the pump‘s operating temperature.
In case of excess temperature, the motor is shut down by a thermal cutout in the
winding. Attention: Reset possible only manually. Switch off the pump or isolate the
equipment from mains. Determine and eliminate the cause of failure. Wait approx.
ve minutes before restarting the pump.
Attention: In case of supply voltage below 100V, the lock of the cutout might be
restricted and the pump might restart on its own after sufcient cooling down. Take
suitable precautions, if an automatic restart of the pump might lead to a dangerous
situation.
A warm up period (approx. 15 min.) is required to ensure that the rated ultimate
vacuum and pumping speed are attained.
ME 4R NT:
Use the vacuum adjustment device at the inlet port of the pump to control the vacuum in the system. By turning the dispensing screw the amount of gases pumped
from the vacuum system can be controlled:
• Turning the dispensing screw to the left: vacuum is decreased (higher pressure)
(Pump additionally takes in bleed air via dispensing screw.)
• Turning the dispensing screw to the right: vacuum is increased (lower pressure)
NOTICE
The overpressure at the outlet port of the pump is controlled accordingly via the
pressure adjustment device:
• Turning the dispensing screw to the left: pressure is decreased (Pump blows off
via dispensing screw.)
• Turning the dispensing screw to the right: pressure is increased (attention: max.
4 bar permitted!)
Shutdown
Short-term:
Has the pump been exposed to condensate?
Allow the pump to continue to run at atmospheric pressure for a few minutes.
Has the pump been exposed to media which may damage the pump materials or
form deposits?
Check and clean pump heads if necessary.
Long-term:
Take measures as described in section short-term shutdown.
Separate pump from the apparatus.
Close inlet and outlet port (e. g. with transport caps).
Store the pump in dry conditions.

Replacing diaphragms and valves
All bearings are encapsulated and are lled with long-life lubricant. Under normal
NOTICE
operating conditions, the pump is maintenance free. The valves and diaphragms as
well as the motor capacitors are wear parts. If the rated ultimate vacuum is no longer
achieved or in case of increased noise level, the pump interior, the diaphragms and
the valves must be cleaned and the diaphragms and valves must be checked for
cracks or other damage. Check every capacitor regularly by measuring its capacity
and estimating its operation time. Exchange old capacitors early enough to prevent
a failure. The capacitors have to be replaced by an electrician. Depending on in-
dividual cases it may be efcient to check and clean the pump heads on a regular
basis. In case of normal wear the lifetime of the diaphragms and valves is > 10000
operating hours.
- Prevent internal condensation, transfer of liquids or dust. The diaphragm and
valves will be damaged, if liquids are pumped in signicant amount.
If the pump is exposed to corrosive gases or vapour or in case of deposits, maintenance should be carried out frequently.
- Regular maintenance will improve the lifetime of the pump and also protect both
man and environment.
Ensure that maintenance is done only by suitable trained and supervised technicians.
☞ 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.
☞ Before starting maintenance isolate the pump from the electrical supply and wait
two minutes after isolating the equipment from mains to allow the capacitors to
discharge. Avoid the release of pollutants. Allow sufcient cooling of the pump.
• 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. Ensure that the maintenance technician is familiar with the safety procedures which relate to the products processed by the pumping system.
• Wear appropriate safety-clothing when you come into contact with contaminated
components. Avoid the release of pollutants.

Replacing the diaphragm
Replacing the diaphragms of a pump MZ 2D NT:
☞ Check the diaphragm for damage and replace if necessary.
➨ Use a Phillips screw driver to remove the countersunk head screw in the centre of the diaphragm
clamping disc.
☞ Attention: The screw is secured with adhesive against loosening. Clean the screw or use a new
one (cat. no.: 63 98 47).
☞ If the old diaphragm is difcult to separate from the support disc, immerse the assembly in naph-
tha or petroleum ether. Do not inhale!
➨ Check for washers between the diaphragm support disc and the connecting rod. Do not mix the
washers from different pump heads. Make sure that the original number is reassembled at the
individual pump head.
☞ Smaller number of washers: The pump will not attain ultimate vacuum. More washers: The clamp-
ing disc will hit the head cover; noise or even blockade and damage of the pump.
☞ Attention: Double diaphragm consisting of two single dia-
phragms! Put the two diaphragms together with the printed
sides outwards.
➨ Apply a drop of adhesive (OmniFit® 50M or Loctite® 243) to
the lower side of the screw head and the thread and screw
diaphragm clamping disc, diaphragm, diaphragm support
disc and washers (if applicable) to connecting rod.

tenance of the remaining pump heads according to the description above.
If the pump does not achieve the ultimate vacuum:
☞ In case the diaphragms and valves have been replaced, a run-in period of several
hours is required before the pump achieves its ultimate vacuum.
☞ In case of unusual noise switch off pump immediately and check clamping disc
positions
If the pump does not achieve the ultimate total vacuum:
Check hose connectors between pump heads and manifolds for leaks. If necessary
recheck pump chamber.
Replacing the device fuse
The replacing of the device fuse has to be carried out by an electrician. Switch off
the pump and disconnect it from mains before opening the terminal box. After disconnecting from mains wait two minutes to allow the capacitors to discharge. After
replacing the fuse, the pump must be checked for electric safety (see below)! Identify
and eliminate the cause of failure before switching on the pump again.
The pigtail fuses (slow blow fuse 6,3A) is built in in a wire (1,
black and blue) inside the terminal box. To replace the fuses
it is necessary to replace the whole wires (xed with at pin
bushes (2)).
➨ Open the terminal box. Unscrew the four screws with a
Torx screw driver TX20 and remove the terminal box cov-
er. Remove the wire with the blown fuse (xed with at
