Dear customer,
Your VACUUBRAND diaphragm pumps are designed to provide you with many years of trouble-free service with optimal performance. Our many years of practical experience allow us to provide a wealth of application and safety information. Please read these instructions for use before the initial operation of your pump. VACUUBRAND diaphragm pumps combine our many years of experi­ence in design, construction and practical operation, with the latest de­velopments in material and manufacturing technology.
Our quality maxim is the ”zero defect” principle: Every diaphragm pump, before leaving our factory, is tested intensively, including an endurance run of 14 hours. Any faults, even those which oc-
cur rarely, are identied and can be eliminated immediately.
After completion of the endurance run, every pump is tested, and must
achieve specications before shipment.
We are committed to providing our customers only pumps that meet this high quality standard. While our pumps cannot eliminate all of your work, we design, manufac­ture and test them to ensure that they will be an effective and trouble-free tool to assist you in that work.
Yours, VACUUBRAND GMBH + CO KG

+ Comply with all notes on correct vacuum and electri-
cal connections; see section “Use and operation”, pg.
35.
+ Do not use the pump to generate pressure.
+ The pumps are designed for ambient temperatures
during operation between +50°F and +104°F (+10°C and +40°C). Periodically check maximum tempera­tures if installing the pump in a cabinet or a housing. Make sure ventilation is adequate to maintain recom­mended operating temperature. Install an external au­tomatic ventilation system if necessary. If pumping hot process gases, make sure that the maximum permitted
NOTICE
gas inlet temperature is not exceeded. The maximum permitted gas inlet temperature depends on several parameters like inlet pressure and ambient tempera­ture (see “Technical data”, pg. 25).
+ Particles and dust must not enter the pump. + Do not pump liquids.
• Ensure that the pump is chemically resistant to the
pumped substances prior to operation.
Use the equipment only as intended, that is, for genera­tion, measurement, and control of vacuum in vessels de­signed for that purpose. The equipment may only be used indoors in a non-explosive atmosphere. Any other use will automatically invalidate all warranty and liability claims. Remain aware of safety and risks.

Setting up and installing the equipment

➨ Equipment must be connected only to a suitable elec-
trical supply and a suitable ground point. As such,
the plug must be plugged into an outlet that is properly grounded. Failure to connect the motor to ground may result in deadly electrical shock.
20901106_EN_MD4_MV2_VARIO_select_V1.0_140818
Page 15
page 15 of 68
The supply cable may be tted with a molded Europe-
an IEC plug or a plug suitable for your local electrical supply. The cable contains wires color coded as fol­lows: green or green and yellow: ground; blue or white: neutral; brown or black: hot.
+ Due to the high compression ratio, the pump may gen-
erate overpressure at the outlet. Check pressure com­patibility with system components (e.g., exhaust pipe­line or exhaust valve) at the outlet.
+ Do not permit any uncontrolled pressurizing. Make
sure that the exhaust pipeline cannot become blocked. If there is an exhaust isolation valve, make sure that you cannot operate the equipment with the valve closed to avoid a risk of bursting!
+ Maximum permissible pressure at the pressure trans-
ducer: 21.8 psi (1.5 bar) absolute.
+ Keep the electrical power cord away from heated sur-
faces.
• Provide a rm, level platform for the equipment. Check
that the system which you are going to evacuate is
mechanically stable. Check that all ttings are secure.
Ensure a stable position of the pump without any me­chanical contact other than the pump feet.
• Comply with maximum permissible pressures at in- let and outlet and with maximum permissible pres- sure differences between inlet and outlet. See section “Technical data”, pg. 25. Do not operate the pump with overpressure at the inlet.
• Comply with maximum permissible pressures at the pressure transducer. See section “Technical data”, pg.
25.
• Avoid overpressure of more than 17.5 psi absolute (1.2
bar absolute) in the event that gas or inert gas is con­nected to the pump, or to a venting valve.
20901106_EN_MD4_MV2_VARIO_select_V1.0_140818
Page 16
page 16 of 68
• Note: Flexible elements will shrink when evacuated.
• Connect hoses gas tight at inlet and outlet of the pump.
• Connect hoses gas tight at the pressure transducer.
• Ensure that no foreign objects can be drawn into the
pump.
• Check the power source and the pump’s rating plate
to be sure that the power source and the equipment match in voltage, phase, and frequency.
NOTICE
Make sure ventilation is adequate to maintain recommend­ed operating temperature. Keep a minimum distance of 2 in (5 cm) between the cooling fan and surrounding items (e.g., housing, walls, etc.), or else install an external auto­matic ventilation system. Check fan regularly for dust/dirt. Clean fan guard grill if necessary to avoid a reduction of ventilation.
Position the pressure transducer and its vacuum line in such a way that condensate cannot ow towards the pres­sure transducer.
Use only hoses at the inlet and outlet of the pump with an inner diameter at least as large as the diameter of the pump’s tubing (to avoid overpressure at the outlet, and reduction of pumping speed at the inlet).
Allow the equipment to equilibrate to ambient temperature if you bring it from cold environment into a room prior to operation. Notice if there is water condensation on cold surfaces.
Comply with all applicable and relevant safety require-
ments (regulations and guidelines). Implement the re­quired actions and adopt suitable safety measures.

Ambient conditions

➨ Do not reach for this product if it has fallen into liquid.
There is a risk of deadly electrical shock. Unplug the system immediately.
+ Do not use this product in an area where it can fall or
be pulled into water or other liquids.
• Adopt suitable measures in case of differences from
recommended conditions, e.g., using the equipment outdoors, installation in higher altitudes, conductive pollution or external condensation on the pump.
• Do not operate this product near ames.
NOTICE
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 EN 61010-1 gives in detail the conditions under which the equipment can be operated safely (see also IP degree of protection, “Technical data”, pg. 25).

Operating conditions

➨ These pumps are not approved for operation in po-
tentially explosive atmospheres. Do not operate the pumps in potentially explosive atmospheres.
➨ Pumps without the ” ” mark on the rating plate are
not approved for the pumping of potentially explo­sive atmospheres. Do not pump potentially explo­sive atmospheres with those pumps
➨ Pumps bearing the ” ” mark on their rating plates
are approved for the pumping of potentially ex- plosive atmospheres according to their ATEX clas-
sication imprinted on their rating plate, but they are
not approved for operation in potentially explosive atmospheres(see section “
Equipment marking (ATEX)”, pg. 23).
20901106_EN_MD4_MV2_VARIO_select_V1.0_140818
Important information:
`
Page 18
page 18 of 68
➨ The pumps are not suitable to pump any of the sub-
stances listed below.
Do not pump:
- unstable substances
- substances which react explosively under impact (mechanical stress) without air
- substances which react explosively when being ex­posed to elevated temperatures without air,
- substances subject to auto-ignition,
- substances which are inammable without air
- explosive substances.
➨ The pumps are not approved for operation below
ground. Do not operate the pump below ground.
• Do not pump substances which may form depos- its inside the pump. 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 exceeding the maximum permitted temperatures.
• Check the inlet and outlet of the pump, if there is a
danger of forming deposits inside the pump, e.g., in the pump chambers (the pump chamber is the part between diaphragm and head cover. See section “Re­placing diaphragms and valves”, pg. 52). Inspect the pump chambers regularly and clean if necessary.
• Consider interactions and chemical reactions of the pumped media. Ensure that the materials of the
pump’s wetted parts are compatible with the pumped substances, see section “Technical data”, pg. 25.
When changing the substances pumped, we recom-
mend purging the pump with air or inert gas prior to changing the pumped media. Purging the pump will pump out residues and it will reduce the possibility of reactions of the pumped substances with each other and with the pump’s materials.

Safety during operation

➨ Adopt suitable measures to prevent the release of dan-
gerous, toxic, explosive, corrosive, noxious or pollut-
ing uids, vapors and gases. To prevent any emission
of such substances from the pump outlet, install an appropriate collecting and disposal system and take protective action for pump and environment.
➨ You must take suitable precautions to prevent any for-
mation of explosive mixtures in the pump chamber or at the outlet of the pump. In case, e.g., of a diaphragm failure, mechanically generated sparks, hot surfaces or static electricity may ignite these mixtures. Use inert gas for venting, if necessary.
➨ Drain appropriately or otherwise remove any poten-
tially explosive mixtures at the outlet of the pump, or dilute them to non-explosive concentrations.
➨ Never operate this pump if it has a damaged cord or
plug.
+ If the pump is not working properly, has been dropped
or has fallen into water, contact your pump service pro­vider.
+ Prevent any part of the human body from coming into
contact with vacuum.
+ Make sure that the exhaust pipeline cannot become
blocked.
+ Attention: At pressures above approximately 810 Torr
(1080 mbar) the pressure reading becomes incorrect. The display ashes and a warning message is dis­played. Release pressure immediately! Risk of burst­ing!
+ Comply with applicable regulations when disposing of
chemicals. Take into consideration that chemicals may

be contaminated. Take adequate precautions to pro­tect people from the effects of dangerous substances (chemicals, thermal decomposition products of uoro­elastomers). Use appropriate protective clothing and safety goggles.
+ Interruption of the pump (e.g., due to power failure),
failure of connected components or of parts of the sup­ply, or change in parameters must not be allowed to lead to dangerous conditions. In case of a diaphragm failure or in case of a leak in the manifold, pumped substances might be released into the environment or into the pump housing or motor.
Comply with all notes regarding proper use of the
pumps, as well as operation and maintenance guid­ance.
+ The residual leak rate of the equipment might render
possible 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.
• Ensure that no parts of your clothing, hair or ngers
can be caught or drawn in at the inlet of the pump.
Never insert ngers or drop any other object into the
inlet or outlet.
• You must take suitable precautions to prevent any
dangerous situation from arising if the controller starts the VARIO pump, switches a coolant valve or opens a venting valve.
• Attention: If the controller is set to Autostart, the pro- cess will start immediately when switching on the device or in case of power recurrence after a power failure. It is your responsibility to ensure that automatic start-up of the system will not lead to any dangerous condition. Provide appropriate safety measures. Check prior to starting the process whether the option ”Autostart” (menu: Settings\Basic Settings) is enabled.

• Pay attention to the safety symbol ”hot surfaces” on the equipment. Hot parts may cause burns if touched. Adopt suitable measures to prevent any danger aris­ing from hot surfaces or electric sparks. Ensure that hot surfaces of the pump do not cause burns. Provide a suitable contact guard if necessary.
NOTICE
Prevent the backpressure of gases and the backow of
condensates at the outlet.
Provide appropriate protective measures to allow for the possibility of failure and malfunction. The protective mea­sures must also allow for the requirements of the respec­tive application.
In case of overload, the motor is shut down by a self-hold
thermal cutout in the winding. Note: Only manual reset is possible. Acknowledge the er-
ror message at the controller. Switch off the pump and disconnect from the power source. Identify and eliminate the cause of failure. Wait approx. ve minutes before re­starting the pump.
NOTICE

Maintenance and repair

In order to comply with laws (occupational, health and safety regulations, safety at work law and regulations for environmental protection) vacuum pumps, components and measuring instruments can only be returned when certain procedures (see section “Repair - Maintenance ­Return - Calibration”, pg. 60) are followed.
Take advantage of our service seminars, which put special focus on the maintenance and repair of vacuum pumps. For details and for the online ”Instructions for repair” man­ual see www.vacuubrand.com.

In normal use, the lifetime of the diaphragms and valves is typically 15,000 operating hours. Bearings have a typical durability of 40000 h.
➨ Ensure that the pump cannot be operated acciden-
tally. Never operate the pump if covers or other parts of the pump are disassembled.
➨ Switch off the pump. Disconnect the electrical
power cord and wait two minutes before starting
maintenance to allow the capacitors to discharge.
➨ Note: The pump may be contaminated with process
chemicals, which have been pumped during operation. Ensure that the pump is completely decontaminated
NOTICE
before maintenance commences.
+ Take adequate precautions to protect people from the
effects of dangerous substances if contamination has occurred. Use appropriate protective clothing, safety goggles and protective gloves.
+ Wear parts have to be replaced regularly. + Never operate a defective or damaged pump. + Vent the pump before starting maintenance. Isolate the
pump and other components from the vacuum system.
Allow sufcient cooling of the pump.
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. Only dismantle the pump as far as necessary.

Important information: Equipment marking (ATEX)
`
VACUUBRAND equipment bearing the ATEX mark
(see rating plate)
The classication according to ATEX is only valid for the inner part (wet­ted part, pumped gas or vapor) of the equipment. The equipment is not suitable for use in external, potentially explosive atmospheres (environ­ment).
The overall category of the equipment depends on the connected com-
ponents. If the connected components do not comply with the classi­cation of the VACUUBRAND equipment, the specied category of the
VACUUBRAND equipment is no longer valid.
Vacuum pumps and vacuum gauges in category 3 are intended for con­nection to equipment in which during normal operation explosive atmo­spheres caused by gases, vapors or mists normally don’t occur; or, if they do occur, are likely to do so only infrequently and for a short period only. Equipment in this category ensures the requisite level of protection dur­ing normal operation. The use of gas ballast or the operation of venting valves is only permit­ted if thereby explosive atmospheres normally don’t occur in the interior of the equipment or, if they do occur, are likely to do so only infrequently and for a short period.
The pumps are marked with ”X” (according to EN 13463-1), i.e., restric­tions of the operation conditions:
• The equipment is designated for a low degree of mechanical stress
and has to be installed in a way so that it cannot be damaged from outside.
Pumping units have to be installed so that they are protected against
shocks from the outside and against glass splinters in the event of breakage (implosion).
20901106_EN_MD4_MV2_VARIO_select_V1.0_140818
Page 24
page 24 of 68
• The equipment is designated for an ambient and gas inlet temperature
during operation of +10 to +40°C. Never exceed these ambient and gas inlet temperatures. If pumping / measuring gases which are not potentially explosive, extended gas inlet temperatures are permissible. See instructions for use, section “Gas inlet temperatures” or “Techni­cal data”.
After any intervention at the equipment (e.g., repair / maintenance) the ul­timate vacuum of the pump has to be checked. Only if the pump achieves its specied ultimate vacuum is the pump’s leak rate low enough to en­sure that no explosive atmospheres will occur in the interior of the equip­ment. After any intervention at the vacuum sensor, the leak rate of the equip­ment has to be checked.
Attention: This manual is not available in all languages of the EU. The user must not op­erate the device if he does not understand this manual. In this case a technically cor­rect translation of the complete manual has to be available. The manual must be com­pletely read and understood before opera-
tion of the device. All specied measures
must be applied, or else must be replaced by equivalent measures at the user’s own risk.

Use and operation

Apart from a short description of the VACUU·SELECT® operating panel,
this manual describes the mechanical structure of the diaphragm pump.
Operation of the VACUU·SELECT® vacuum controller and its func­tions are described in the separate VACUU·SELECT® manual.

Installing a pump in a vacuum system

➨ If dangerous or polluting uids could be released at
the outlet, install an appropriate system to catch and
dispose of those uids.
+ Connect a gas-tight exhaust line at the pump outlet if
necessary. Always vent exhaust gases appropriately (e.g., into a fume hood).
+ Never block the gas outlet. The exhaust line must al-
ways be free of obstructions (no back pressure) to en­sure an unimpeded discharge of gas. The cross-sec­tion of the outlet tubing must be at least the size of the pump’s exhaust connection.
+ Maximum permissible pressure: 21.8 psi (1.5 bar) ab-
solute.
+ Attention: At pressures above approximately 810 Torr
(1080 mbar) the pressure reading becomes incor­rect. The display will ash and a warning message will be displayed. Release pressure immediately! Risk of bursting!
+ Particles and dust must not be aspirated. If necessary,
you must install appropriate lters. You must ensure their suitability concerning gas ow, chemical resis-
tance and resistance to clogging prior to use.
+ Make sure ventilation is adequate, especially if the pump
is installed in an enclosure, or if the ambient temperature is elevated. Provide external ventilation, if necessary.
20901106_EN_MD4_MV2_VARIO_select_V1.0_140818
Page 36
page 36 of 68
• Reduce the transmission of vibration. Prevent mechan­ical load due to rigid pipelines. Insert elastic hoses or
exible elements as couplings between the pump and
rigid pipes.
Note: Flexible elements will compress or atten when
evacuated if not designed for use under vacuum.
• Hose connections at the pump inlet must always be
gas tight.
• A power failure may cause accidental ventilation of the
pump. If this constitutes a potential source of danger, take appropriate safety measures.
• Check the power source and the pump’s rating plate
NOTICE
to be sure that the power source and the equipment match in voltage, phase, and frequency.
Make sure ventilation is adequate to maintain recommend­ed operating temperature. Keep a minimum distance of 2 in (5 cm) between the cooling fan and surrounding items (e.g., housing, walls, etc.), or else install an external auto­matic ventilation system.
Use connecting hoses with large diameter and keep them
as short as possible to avoid ow losses. Locate the pump
as closely as possible to the application. Always install outlet tubing descending from the pump or
provide other measures to avoid backow of condensate
towards the pump.
Use a suitable valve to isolate the pump from the vacuum application. This is to allow the pump to warm up before pumping condensable vapors and to clean the pump after use 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, e.g., with hose clamps, to protect against accidental detach­ment.

VACUU•SELECT Controller

Connect the VACUU·SELECT operating panel to the
VACUU·BUS cable of the VARIO diaphragm pump.
For proper operation of the VARIO select pump a pres­sure transducer (e.g., VACUU·SELECT Sensor, etc.) has to be connected to the operating panel.
The VACUU·SELECT Controller can only be operated with components compatible with the VACUUBRAND VACUU·BUS system, (see “Accessories”, pg. 48). The vacuum controller controls VACUUBRAND VARIO diaphragm pumps and optional coolant and venting
NOTICE
valves. Connected components (e.g., venting valves,
VACUU·SELECT Sensor, etc.) are automatically identi­ed when switching on the operation panel. Identical com­ponents must be congurated beforehand, see manual of VACUU·SELECT Controller.
Attention: Do not apply off-axis forces when assembling or removing plug connections! Observe correct orienta­tion of the plug. To connect further components use VACUU·BUS Y-adapt­ers and extension cables.
Do not use more than one controller within the same VACUU·BUS system. Several controllers in the same VACUU·BUS system will interfere with each other and result in error mes­sages of the connected components (pumps, valves).
VACUU·SELECT Sensor
The VACUU·SELECT Sensor is equipped with a capaci­tive pressure transducer with ceramic diaphragm. It mea­sures the actual pressure independently of the gas type, and with reference to the vacuum, i.e., absolute.
Connect the VACUU·SELECT Sensor via the VACUU·BUS
cable to the operating panel.
20901106_EN_MD4_MV2_VARIO_select_V1.0_140818
Page 38
page 38 of 68
Connect the VACUU·SELECT Sensor via hose or small ange connection to the vacuum application. Do not mount
the sensor directly at the pump but close to the applica­tion. The cross-section of the tubing should be as large as possible.
Inside a vacuum system where evaporation occurs, e.g., a rotary evaporator, the vacuum is not uniform. For ex­ample, a condenser can act as a pump, or the vacuum in the connecting tubing can be higher or lower than in the application itself. This affects the measurement results as well as the control levels. Therefore, carefully choose the position where to connect the sensor.
Position the VACUU·SELECT Sensor and its vacuum line in such a way that condensate cannot ow towards the
pressure transducer. Condensate and deposits will affect the measurement results. Clean the pressure transducer, if necessary. See section “Cleaning the pressure trans­ducer”, pg. 47.
Installing the hose nozzle at the VACUU·SELECT Sen­sor:
Unscrew the small ange. Slip hose nozzle with clamping
ring onto the vacuum connection and fasten with union nut.
VACUU·BUS
The VACUU·SELECT controller uses VACUU·BUS proto­col to read out the pressure transducer via VACUU·BUS line. Maximum cable length inside buildings: 32yd (30m). VACUU·BUS extension cable 2.2 yd (2 meters): order-no.

During operation

➨ Vent and dispose of potentially dangerous gases or
vapors at the outlet of the pump appropriately.
+ Due to the high compression ratio, the pump might
generate overpressure at the outlet. Check pressure compatibility with system components (e.g., exhaust tubing or exhaust valve) at the outlet. Ensure that the pump outlet is neither blocked nor restricted.
+ Maximum ambient temperature: 104 °F (40 °C) Check the maximum temperatures, if installing the
pump in a cabinet or a housing. Make sure ventilation is adequate, especially if the ambient temperature is elevated.
+ Operation with silencer at the outlet: Operating the
pump at a high inlet pressure or pumping dusty gas­es for a long time may cause clogging of the silencer. Check the silencer regularly and replace if necessary, or install a hose nozzle (order no. 20639758) with seal­ing ring (order no. 20639729) instead.
• If the pump is installed at an altitude of more than 6500
ft (2000 m) above mean sea level, check compatibility with applicable safety requirements, and adopt suit­able measures. There is a risk of the motor overheat-
ing due to insufcient cooling.
NOTICE
• Check compatibility with the maximally permitted pressure at outlet and the maximum pressure dif­ference between inlet and outlet ports.
Do not start the pump if the pressure difference between inlet and outlet ports exceeds max. 16.0 psi (1.1 bar).
Attempts to start the pump at higher pressure difference may cause stalling and damage of the motor.
20901106_EN_MD4_MV2_VARIO_select_V1.0_140818
Page 42
page 42 of 68
Prevent internal condensation, transfer of liquids or dust. The diaphragms and valves will be damaged, if liquids are
pumped in signicant amounts.
Check the pump regularly for external soiling and depos­its. Clean the pump if necessary to avoid an increase of the pump’s operating temperature. In case of overload, the motor is shut down by a self-hold
thermal cutout in the winding. Note: Only manual reset is possible. Acknowledge the er-
ror message at the controller. Switch off the pump and disconnect from the power source. Identify and eliminate the cause of failure. Wait approx. ve minutes before re­starting the pump.
Check fan regularly for dust/dirt. Clean if necessary. Avoid overheating (e.g., due to hot process gases).
A warm up period (approximately 15 min.) is required to ensure that the rated ultimate vacuum and pumping speed are attained.

Readjustment of vacuum sensor

NOTICE
The device was adjusted using factory standards, which are traceable through regular calibration in an accredited laboratory (DAkkS calibration laboratory) to the German national pressure standard. Depending on the process and/or accuracy requirements, check the adjustment and readjust if necessary. For readjustment, the device has to be adjusted both at atmospheric pressure as well as un­der vacuum but only if the reference pressures are known with certainty. In the range between 15 to 525 Torr (20 to 700 mbar) no adjustment is possible.
Adjustment at atmospheric pressure
An adjustment at atmospheric pressure is only possible if the pressure is higher than 525 Torr (700 mbar). Vent the measurement connection of the vacuum sensor (e.g., VACUU•SELECT Sensor) and/or the vacuum sys- tem. Make sure that the measurement connection of the vacuum sensor is at atmospheric pressure.
Note: To determine the actual atmospheric pressure, use an accurate barometer or get accurate reading from the weather service, or a nearby airport or other reliable source (taking into account the difference in altitude be­tween the source and the laboratory).
Adjustment under vacuum or at a reference pressure
An adjustment under vacuum is only possible if the pres­sure is lower than 15 Torr (20 mbar) absolute. Evacuate the measurement connection of the vacuum sensor to a pressure < 0.1 Torr (mbar) (e.g., by applying a good two-stage rotary vane pump).
20901106_EN_MD4_MV2_VARIO_select_V1.0_140818
Page 45
page 45 of 68
Note: Adjustment under vacuum with an actual pressure higher than 0.1 Torr (mbar) reduces the accuracy of the measurement. If the pressure is signicantly higher than
0.1 Torr (mbar), adjustment to a reference pressure is rec­ommended.
Instead of adjustment under vacuum to a pressure < 0.1 Torr (mbar), adjustment to a precisely known reference
pressure within the range of 0..... 15 Torr (20 mbar) is
possible. Evacuate the measurement connection of the
vacuum sensor to a pressure within 0 ..... 15 Torr (0.....20
mbar).
Note: The accuracy of the value of the reference pressure will directly affect the accuracy of the adjustment. If the nominal ultimate vacuum of a diaphragm pump is used as reference vacuum, the accuracy of the vacuum sensor might be doubtful. The diaphragm pump may not achieve the specied value (due to condensate, poor condition, failure of valves or diaphragm, leaks).

Replacing diaphragms and valves

+ Please read section ”Replacing diaphragms and valves” com-
pletely before starting maintenance.
The pictures may show other versions of pumps. This does not change
the method of replacing diaphragms and valves.
➨ Never operate the pump if covers or other parts of
the pump are disassembled.
➨ Before starting maintenance, disconnect the electri-
cal power cord. Wait two minutes after isolating the
equipment from AC power to allow the capacitors to discharge.
➨ Ensure that the pump cannot be operated accidentally. ➨ Note: The pump might be contaminated with the pro-
cess chemicals that have been pumped during opera­tion. Ensure that the pump is decontaminated before maintenance.
➨ Avoid the release of pollutants.
+ Never operate a defective or damaged pump.
+ Take adequate precautions to protect people from the
effects of dangerous substances that may have con­taminated the pump and may be released upon dis­assembly. Ensure that the maintenance technician is familiar with the safety procedures which relate to the products processed by the pumping system.
Use appropriate protective clothing, safety goggles
and protective gloves.
+ Allow sufcient cooling of the pump before starting
maintenance.
+ Vent the pump and isolate it from the vacuum sys-
tem before you start maintenance.
20901106_EN_MD4_MV2_VARIO_select_V1.0_140818
Page 53
page 53 of 68
NOTICE
Ensure that maintenance is done only by suitably
trained and supervised technicians.
The valves and diaphragms 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.
All bearings are encapsulated and are lled with long-life
lubricant. Under normal operating conditions, the drive system is maintenance free.
In demanding circumstances, it may be efcient to check
and clean the pump heads on a regular basis. In normal use, the lifetime of the diaphragms and valves is typically 15,000 operating hours.
- Prevent internal condensation, transfer of liquids or dust. The diaphragms and valves will be damaged if
liquid is pumped in signicant amount.
- Carry out maintenance frequently if the pump is ex­posed to corrosive media or in case of deposits.
- Regular maintenance will improve the lifetime of the pump and also protect both users and the environment.

➨ Disassemble the housing cover (A) to check
the valves (C).
➨ Unscrew eight Allen screws with a 5mm
wide Allen key. Remove the housing cover (A) together with head cover (D), valves (C) and O-rings (B).
+ Never use a pointed or sharp-edged tool to remove parts (e.g., screw-
driver). We recommend to use a rubber mallet or compressed air (to be blown carefully into port).
➨ Remove the head cover (D) carefully from the housing cover (A). Note
position and alignment of valves (C). Remove the valves.
+ Replace valves or O-rings if necessary. + Use petroleum ether or other industrial solvent to remove deposits. Do
not inhale vapors.
+ Underneath the pump there is a connecting tube (K) between the two
housing covers. The connecting tube is merely stuck into the housing covers and sealed with seal rings at the connecting tube’s ends. If the housing cover is removed, the connecting tube becomes detached as well.

Replacing the diaphragm

+ Check diaphragm (F) for damage and re-
place if necessary.
➨ Lift diaphragm carefully sidewise. + Never use a pointed or sharp-edged tool to
E
F
lift the diaphragm.
➨ Use the diaphragm key to grip the diaphragm
support disc (G) below the diaphragm.
➨ Unscrew diaphragm support disc (G) with diaphragm (F) and dia-
phragm clamping disc (E).
➨ Check for washers (H) between the diaphragm support disc (G) and
the connecting rod (I). Do not mix the washers from the different pump heads, since these are set at the factory to ensure proper pump per­formance. Make sure that the original number is reassembled at the individual pump head.
20901106_EN_MD4_MV2_VARIO_select_V1.0_140818
Page 56
page 56 of 68
+ Too few washers: The pump will not attain vacuum specication. Too
many washers: Diaphragm clamping disc will hit head cover, causing noisy operation and possibly causing the pump to seize up.
+ If the old diaphragm is difcult to separate from the diaphragm support
disc, immerse assembly in naphtha or petroleum ether. Do not inhale vapors!
F
➨ Position new diaphragm (F) between dia-
phragm clamping disc with square head screw (E) and diaphragm support disc (G).
+ Note: This is a double diaphragm consist-
E
ing of two single diaphragms! Put the two
G
diaphragms together with the printed sides outwards.
+ Make sure that the square head screw of the diaphragm clamping disc
is correctly seated in the guide hole of the diaphragm support disc.
➨ Lift the diaphragm at the side. Place the diaphragm carefully together
with diaphragm clamping disc and diaphragm support disc in the dia­phragm key.
+ Avoid damage of the diaphragm: Do not excessively bend or crease
the diaphragm.
+ Assemble the original number of washers
(H) between diaphragm support disc (G) and connecting rod (I).
➨ Screw diaphragm clamping disc (E), dia-
E
F
phragm (F), diaphragm support disc (G), and washers (H) to connecting rod (I).
➨ Optimum torque for the diaphragm support disc: 4.4 ft.lbf (6 Nm), it is
recommended to use a torque wrench. Attach torque wrench to dia­phragm key (hexagonal bolt 6 mm wide).
Note: Never use the diaphragm key with any additional tools like tongs
or Allen keys without appropriate torque limitation.

Assembling the pump heads

➨ Bring the diaphragms (F) into a position, in
which they are in contact with the housing (J) and centered with respect to the bore.
(K)
➨ Put on head covers (D). + Pay attention to the correct orientation of the
head covers: Align the nib at the head cover (D) with the notch of the housing cover (A).
+ Make sure that the diaphragm stays cen-
(1)
tered with respect to the bore so that it will become clamped uniformly between hous­ing (J) and head cover (D).
➨ Put the valves (C) an O-rings (B) in place. See gure for the correct
position of the valves:
Inlet side of pump head: The valve tongue points at the kidney-shaped
orice in the valve seat (1).
Outlet side of pump head: The valve is oriented the same direction as
the valve at the inlet side.
➨ Put on housing cover (A). + If it is not possible to position the housing cover, check the head cov-
ers for correct orientation. The nib at the head cover has to lock into the notch of the housing cover.
➨ Install the connecting tube (K) under the pump between the two housing
covers. Pay attention to the correct positions of the seal rings (replace if damaged) in the grooves at the ends of the tube. Fit the connecting tube in the bore of the housing cover. After assembly the connecting tube may have some play.
➨ Screw in the Allen head screws at the head
covers diagonally at rst slightly with a 5
mm wide Allen key, then tighten.
+ Recommended torque: 8.9 ft

page 58 of 68
Replace diaphragms and valves of the opposite side of the pump in the same way!
Checking the ultimate vacuum
➨ After any intervention at the equipment (e.g., repair / maintenance)
the ultimate vacuum of the pump has to be checked. Only if the pump
achieves its specied ultimate vacuum, the pump’s leak rate is low
enough to ensure that no explosive atmospheres will occur in the inte­rior of the equipment.
After any intervention at the vacuum sensor the leak rate of the equip-
ment has to be checked.
If the pump does not achieve the ultimate vacuum:
- Whenever the diaphragms and valves have been replaced, a break-in period of several hours is required before the pump achieves its ulti­mate vacuum.
- In case of an unusual noise, switch off pump immediately and check clamping disc positions.
If the specied ultimate vacuum is not achieved, and if this does not
change after the break-in period: If necessary recheck valve seats and pump chambers.
