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 efficient 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 18 hours. Due to this
endurance run, also faults, which occur rarely, are reported an can be corrected. Every single diaphragm
pump is tested on achievement of the specification after the endurance run.
Every VACUUBRAND pump leaving our factory achieves the specification. 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 troublefree realisation of your work.
Yours
VACUUBRAND GMBH + CO KG
After sales service: Contact your local dealer or call +49 9342 808-193.

ated according to their design and as indicated in the instructions for use.
page 4 of 49
Comply with national safety regulations and safety requirements concerning the
use of vacuum and electrical equipment.
☞ The mains switch for the controller and the pump is at the rear side of the controller.
☞ After switching off the pump, wait 60 sec. minimum until next switching on.
☞ Equipment must be connected only to a suitable fused and protected electrical
supply and a suitable earth point. Failure to connect the pumping unit to ground
may result in deadly electrical shock.
☞ The supply cable may be fitted with a moulded European IEC plug or a plug suitable
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.
☞ Check that mains voltage and current conform with the equipment (see rating plate).
☞ 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).
☞ Make sure ventilation is adequate if pump is installed in a housing or if ambient
temperature is elevated.
Comply with all relevant safety requirements (regulations and guidelines) and adopt
suitable safety measures.
☞ Provide a firm level platform for the equipment and check that the system to be
evacuated is mechanically stable and that all fittings are secure.
Attention: Flexible elements tend to shrink when evacuated.
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.
☞ Comply with maximum permitted pressures and pressure differences, see sec-
tion ”Technical data”. Do not operate the pump with overpressure at the inlet.
Do not permit any uncontrolled pressurizing (e. g. make sure that the exhaust pipeline 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!
☞ Ensure that the system design does not allow the exhaust pipeline to become
blocked.
☞ Max. permitted pressure at the pressure transducer: 1.5 bar (absolute).

☞ Ensure that the system design does not allow the coolant outlet pipeline to become
blocked.
☞ Secure coolant hoses at the hose nozzles (e.g. with hose clip) to prevent their
accidental slipping.
☞ Check liquid level in both catchpots regularly and drain condensate in time.
☞ Check the overpressure safety relief device at the exhaust waste vapour condenser
in appropriate intervals.
☞ Avoid overpressure of more than 0.2 bar in case inert gas is connected.
☞ The diameter of the inlet and outlet pipeline should be at the least as large as the
diameter of the pump connection pipelines.
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 IEC 1010. 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 symbol “hot surfaces“ on the equipment (according to IEC 1010 recommendation).
☞ Adopt suitable measures to prevent any danger arising from the formation of hot
surfaces or electric sparks.
The pumps have no approval for operation in or for pumping of potentially explosive atmospheres.
If pumping different substances, purge the pump with 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 with and the pump material.
Take into consideration interactions and chemical reactions of the pumped media.
The pumps are not suitable for pumping substances which may form deposits inside
the pump.
☞ If there is a danger of the formation of deposits in the pump chamber (check inlet
and outlet of the pump) inspect the pump chamber regularly and clean if necessary.
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.
The pumps are not suitable to pump self inflammable substances, substances which
are inflammable without air and explosive substances.
The pumps are not suitable for pumping dust and have no approval for operation
below ground.
Ensure that the materials of the wetted parts are compatible with the pumped substances, see section “Technical data”.
☞ Adopt suitable measures to prevent the release of dangerous, explosive, corrosive
or polluting fluids.
☞ Use inert gas for gas ballast if necessary.
☞ The user must take suitable precautions to prevent any formation of explosive
mixtures in the pump. In case of a diaphragm crack, mechanically generated sparks,
hot surfaces or static electricity may ignite these mixtures.
☞ Take adequate precautions to protect people from the effects of dangerous sub-
stances, wear appropriate safety-clothing.
☞ Comply with applicable regulations when disposing of chemicals. Take into consid-
eration that chemicals may be polluted.
The motor is protected by a temperature sensor at the circuit board: Current limitation if the temperature at the circuit board is higher than 70°C, switching off the pump
if the temperature is higher than 85°C.

page 6 of 49
In case of blockade of the motor (after 10 attempts to start-up) the pump is switched off.
☞ If the pump is switched off due to safety measures, manual reset is necessary.
Isolate the pump from mains. Eliminate cause of failure before restarting the pump.
☞ Avoid high heat supply (e. g. due to hot process gases).
☞ Ensure sufficient air admittance if pump is installed in a housing.
Due to the residual leak rate of the equipment, there may 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.
Pumping at high inlet pressure may lead to overpressure at the gas ballast valve.
☞ Pumped gases or condensate might be pushed out if the valve is open.
☞ If an inert gas supply is connected, ensure that the inlet pipeline is not contaminated.
The controller is equipped with a short circuit proof transformer with an integrated
overload protection (no fuses).
☞ 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.
Electronic equipment is never 100% fail-safe. This may lead to an indefinite status of
the equipment. Provide protective measures against misfunction and failure.
☞ Operating the pump with high or low frequency, stand still of the pump or operating
the venting valve must not lead to a critical dangerous situation under any circum-
stances.
Ensure that in case of failure the pump and the vacuum system always will turn into a
safe status.
☞ In case of diaphragm cracks or leaks in the manifold 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.
☞ Comply especially with notes on operation and use and maintenance.
Use only genuine spare parts and accessories.
☞ Otherwise safety and performance of the equipment as well as the electromagnetic
compatibility of the equipment might be reduced.
☞ Possibly the CE mark or the C/US conformity becomes invalid if not using genuine
spare parts.
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 product processed by the vacuum system and that the equipment, if
necessary, is appropriately decontaminated before starting maintenance.
Comply with local and national safety regulations.
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.
Before starting maintenance vent the system, isolate the pump and other components
from the vacuum system and the electrical supply, drain condensate and allow sufficient 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.
Never operate a defective or damaged pump.
Repair of the gauge head VSK 5 is not possible.
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.

Use and operation
Installing in a vacuum system:
☞ Avoid throttling losses by using connecting pipes with large diameter and keep
them as short as possible.
☞ Reduce the transmission of vibration and prevent loading due to rigid pipelines.
Insert elastic hoses or flexible elements as couplings between the pump and rigid
pipes. Attention: Flexible elements tend to shrink when evacuated.
☞ Use a suitable valve to isolate the pump from the vacuum system to allow the
pump to warm up before condensable vapours are pumped or to clean the pump
before it is switched off.
☞ Connect the exhaust to a suitable treatment plant to prevent the discharge of dan-
gerous gases and vapours to the surrounding atmosphere. Use a catchpot to prevent the drainage of contaminated condensate back into the pump.
Prior to use:
☞ Max. ambient temperature: 40 °C
☞ Make sure ventilation is adequate if pump is installed in a housing or if ambient
temperature is elevated.
☞ If pump is installed in altitudes of more than 1000 m above mean sea level check
compatibility with applicable safety requirements, e. g. IEC 60034 (motor may overheat due to insufficient cooling).
☞ When assembling, ensure vacuum-tightness. After assembly, check the complete
system for leaks.

➨ Attach the pipelines of the coolant circuit to the respective hose nozzles (see im-
age) at the waste 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.
➨➨
➨ Attention: Install hoses of the cooling system in a way to avoid flow / drop-
➨➨
ping of condensed water to the pumping unit (especially cables and electronic parts).
☞ Ensure that the coolant outlet pipeline is always free and that it cannot get blocked.
The exhaust waste vapour condenser enables an efficient
condensation of the pumped vapours at the outlet.
☞ No backflow of condensates.
☞ Controlled recovery of condensates.
☞ Next to 100% solvent recovery.
☞ The isolation cover protects against glass splinters in case
of breaking, acts as thermal isolation to avoid condensation
of humidity and is intended to absorb shocks.

VSK 5
page 13 of 49
☞ The gas outlet (hose nozzle 10 mm) must not be blocked. The exhaust pipeline has
always to be free and pressureless to enable an unhindered discharge of gases.
☞ Connect the exhaust to a suitable treatment plant to prevent the discharge of dan-
gerous gases and vapours to the surrounding atmosphere.
Notes regarding the assembling of the pressure transducer VSK 5
The cable of the gauge head is connected to the female conconnector
for VSK 5
nector at the rear side of the vacuum controller.
The gauge head is connected to the vacuum system with a
union nut using an adapter.
☞ The device is adjusted together with the gauge head at the
factory. If the gauge head is replaced a readjustment is recommended.
Max. permitted pressure at the pressure transducer: 1.5 bar (ab-
solute).
☞ The display flashes at a pressure higher than 1100 mbar.
☞ Comply with max. permitted pressure.
☞ Inside a vacuum system where evaporation occurs, e. g.
rotary evaporator, the vacuum is not uniform, e. g. a condenser acts as pump or the vacuum in the pipeline is lower
than in the system. Therefore carefully choose position where
to connect the gauge head.
The pressure transducer can be disassembled from the inlet of the pumping unit and,
after having unscrewed the adapter, assembled using a small flange connection or a
hose nozzle (included in delivery) directly to the apparatus.
Close the connection at the inlet of the pumping unit using a blind cap (cat. no.: 67 71 50).
☞ Condensate and deposits in the pressure transducer affect the measuring result.
☞ In case of deposits, aggressive or condensable media, install a gas washing bottle
before the pressure transducer if necessary.
☞ In order to avoid malfunction it is important to position the pressure transducer in
the vacuum line so as to avoid flow of condensate towards the pressure transducer.
☞ Clean pressure transducer if necessary, see section “maintenance“.
Hose nozzle (inlet of the pumping unit):
☞ Alternatively the hose nozzle or a second hose nozzle (in-
cluded in delivery) can be assembled at position 1 or 2 at
2
the inlet of the pumping unit.
➨ Change closing screw and hose nozzle. Ensure that the O-
ring is correctly positioned.

Before operation
Page 14
page 14 of 49
During operation:
Do not start or operate the pump if pressure at the outlet is higher than 1.1 bar
absolute. Attempts to start or operate the pump at higher pressure may cause block-
ade and damage of the motor.
☞ Comply with max. permitted pressure at the outlet and max. permitted pressure
difference between inlet and outlet.
The pump achieves its pumping speed, ultimate total vacuum and vapour pump-
ing 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 significant amounts.
☞ Operate the pump with gas ballast valve open to reduce the condensation of pumped
media (water vapour, solvents, ....) inside the pump.
The motor is protected by a temperature sensor at the circuit board: Current limitation if the temperature at the circuit board is higher than 70°C, switching off the pump
if the temperature is higher than 85°C. In case of blockade of the motor (after 10
attempts to start-up) the pump is switched off.
☞ If the pump is switched off due to safety measures, manual reset is necessary.
Isolate the pump from mains. Eliminate cause of failure before restarting the pump.
☞ Avoid high heat supply (e. g. due to hot process gases).
☞ Ensure sufficient air admittance if pump is installed in a housing.
Settings at the controller
☞ Setting of interface parameters, see section “Interface“.
☞ Preselections at the controller, see section “Modes“.
☞ Use and operation of the controller see section “How to operate the controller”.
How to change the pressure units

last operation is flashing.
➨ Press key p▲ or p▼ to change pressure unit. Press key
stop when controller displays the desired pressure unit to
finish the operation mode.
Attention: Important notes regarding the use of gas ballast
☞ Make sure that air/gas inlet through the gas ballast valve never leads to hazardous,
explosive or otherwise dangerous mixtures. If in doubt, use inert gas.
☞ When using air rather than inert gas, risk of significant 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.
For condensable vapours (water vapour, solvents, ...):
☞ Do not pump vapour before pump has reached its operating
temperature and not with gas ballast valve closed.
☞ Open gas ballast valve. Close gas ballast valve by turning
180°.
☞ The gas ballast valve is open if the arrow on the gas ballast
cap points towards the pump.
gas ballast
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.: 999100 / 06/05/2008
☞ With gas ballast valve open ultimate vacuum will be reduced,
pumping speed is decreased.
☞ Use inert gas at the air inlet to avoid the formation of explo-
sive mixtures.
Page 15
page 15 of 49
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
exhaust waste vapour condenser.
Attention: Notes concerning the operation of the exhaust waste vapour condenser
➨ Check hose connections prior to starting operation of the cooling system.
➨ Check coolant hoses regularly during operation.
☞ Ensure that the coolant outlet pipeline is always free and that it cannot get blocked.
☞ Maximum permissible coolant pressure at the exhaust waste vapour condenser:
6 bar (absolute)
☞ 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 cool-
ant hoses).
☞ Permissible range of coolant temperature at the exhaust waste vapour condenser:
-15°C to +20°C
☞ The gas outlet (hose nozzle 10 mm) must not be blocked. The exhaust pipeline has
always to be free and pressureless to enable an unhindered discharge of gases.
☞ Connect the exhaust to a suitable treatment plant to prevent the discharge of dan-
gerous gases and vapours to the surrounding atmosphere.
In case of condensation:
➨ Check liquid level in both catchpots during operation. Avoid overflowing of the catchpots.
☞ Do not overfill the catchpots. 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 at outlet:
➨ Remove joint clip, remove catchpot and drain condensate.
Catchpot at inlet:
➨ Admit air or inert gas (via inlet of pumping unit) to atmospheric pressure. Remove
joint clip, remove catchpot and drain condensate.
➨ Reassemble drained catchpots.
Important: Comply with regulations when disposing solvents/condensates. Reuse if
possible, purify if contaminated.
Shutdown:
Short-term:
Has the pump been exposed to condensate?
☞ Allow the pump to continue to run at atmospheric pressure for a few minutes (con-
tinuous pumping at a setting of 60).
Has the pump been exposed to media which may damage the pump materials or forms
deposits?
☞ Check and clean pump heads if necessary.
Has the pressure transducer been exposed to media which may form deposits?
☞ Clean pressure transducer 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.

How to configurate the controller
The controller CVC 2000II can be adapted to the specific application by choosing the
appropriate mode, vacuum control with or without automatic, continuous pump-
ing with preset pumping speed or VACUU•LAN: The components of the chemistry
vacuum system (coolant valve, venting valve) have to be preset once only. The mode
as from last operation and the preselected values (e. g. for pressure, speed or time for
switching off) are stored. In case of similar operation conditions it is possible to start
immediately, if the preselections are chosen appropriately.
The vacuum controller CVC 2000II offers three modes depending on
- the components of the VACUUBRAND chemistry vacuum system which are con-
nected to the system.
- the specific user and/or process requirements.
In all modes:
☞ If coolant and/or venting valve have been connected and
preselected:
➨ Process-adapted operation of the coolant valve.
➨ Key-driven venting or adjustment of the set point by venting
if process control is active.
Vacuum control:
➨ Position control on preset pressure value.
➨ The pumping speed is adapted to the occurring gas/vapour,
so that the preset pressure value is kept constant.
➨ Operating in equilibrium by continuous adaption of the con-
troller, no abrupt switching of valves.
Vacuum control in automatic mode:
➨ Searching the boiling point and adjusting the set point auto-
matically if the boiling point changes (due to temperature
change, change of ingredients of solutions).
➨ Adjusting the set point automatically after manual setting of
the boiling point (additional automatic mode in operation mode
vacuum control).
➨ Automatic switching off after complete evaporation of the
solvent if preselected.
Continuous pumping with preset pumping speed:
➨ Simple suction, sucking liquids by siphon, drying, sucking
off excess, etc.
➨ Suction with regulated pumping speed.
➨ Pumping down until the ultimate vacuum of the pump is
achieved (e. g. to dry a system).
➨ System controlled by an interface: temporally variable pump-
ing speed to optimize the process conditions (e. g. to dry
sensitive substances).
➨ Setting ”HI”: Optimum pumping speed at every pressure.

switched on again if gas or vapour occur.
➨ Vacuum supply according to the requirements for lock cham-
bers or pumping systems not compressing against atmospheric pressure, e. g. wide range turbomolecular pumps or
cryo pumps.

Readjustment
The vacuum gauge was adjusted using factory standards, which are traceable through
regular calibration in an accredited laboratory (German Calibration service) to the national 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.
The adjustment mode can be activated only if the process control is inactive. Press
key STOP if necessary.
Adjustment at atmospheric pressure
Ventilate the controller and/or the vacuum system. Make sure
that the vacuum connection at the controller is at atmospheric
pressure.
MODE

Note: To determine the actual atmospheric pressure, use an accurate barometer or get accurate reading
from the weather service, the next airport.......(take into account the difference in altitude between e. g.
airport and laboratory).

Adjustment under vacuum
MODE
+
p
Note: Adjustment under vacuum with an actual pressure higher than 0.5 mbar reduces the accuracy of the
measurement. If the pressure is significantly higher than 0.5 mbar, adjustment to a reference pressure is
recommended.
CAL
➨ Press key p▲ or p▼ simultaneously with key MODE, the
controller then switches to the adjustment mode.
☞ The warning triangle and CAL are displayed for approx. 2
seconds.
➨ While CAL is displayed, press key START/STOP.
➨ Use key p▲ or p▼ to adjust the reading to the actual at-
mospheric pressure.
➨ Press key STOP to confirm.
Evacuate the controller to a pressure < 0.5 mbar (e. g. by applying a good rotary vane pump).
➨ Press key p▲ or p▼ simultaneously with key MODE, the
controller then switches to the adjustment mode.
☞ The warning triangle and CAL are displayed for approx. 2
seconds.
➨ While CAL is displayed, press key START/STOP.
☞ The reading is automatically adjusted to ”zero”.
➨ Press key STOP to confirm.
Adjustment at a reference pressure
Instead of adjustment under vacuum to a pressure < 0.5 mbar,
adjustment to a reference pressure within the range of 0 ..... 20
mbar is possible.

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
controller might be doubtful. The diaphragm pump may not achieve the specified value (due to condensate,
poor state, failure of valves or the diaphragm).

How to determine the best distillation conditions
Determine the temperature of the available coolant.
☞ In most cases the coolant temperature is given (e. g. tap water, in house coolant circuit). For maximum
solvent recovery, carefully choose the boiling point of the product (by choosing the vacuum level) and
the bath temperature accordingly.
☞ Determine the lowest boiling point of the product (solvent).
☞ The temperature difference between boiling point of the product and the coolant should be more than
20°C, otherwise low vacuum level will lead to significant loss of solvent.
☞ Select a water bath temperature of 20-30°C above the boiling point of the product to provide sufficient
heat transfer.
Determine the temperature of the bath.
☞ If there is no limitation from the product side, a water bath temperature of 60-70°C is usually recom-
mended (efficient heating with minimum generation of water vapour from the bath).
Example: Vacuum selection for a boiling temperature of 40°C (e. g. ethanol):
☞ The cooling temperature assumed to be 15-20°C.
☞ Water bath temperature 40°C. Wait until temperature is reached.
☞ Determine the vacuum level (for ethanol: 170 mbar) for a boiling point (use published data of solvents).
Reduce pressure until a sufficient level of evaporation is attained or use the mode ”AUTO” of the
controller (distillation fully automatically).

Replacing diaphragms and valves
All bearings are encapsulated and are filled with long-life lubricant. Under normal operating conditions, the pump is maintenance free. The valves and the 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. Depending on
individual cases it may be efficient 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 significant 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
personnel and environment.
Before starting maintenance vent the system, isolate the pump and other components from the vacuum system and the electrical supply. Wait two minutes after iso-
lating the equipment from mains to allow the capacitors to discharge. Drain condensate
if applicable, avoid the release of pollutants. Allow sufficient cooling of the pump. En-
sure 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.
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 coming in contact with contaminated com-
ponents.

Notes on return to the factory
Repair - return - DKD calibration
Safety and health of our staff, laws and regulations regarding the handling of dangerous goods, occupational health and safety regulations and regulations regarding safe
disposal of waste require that for all pumps and other products the “Health and safety
clearance form“ must be send to our office duly completed and signed before any
equipment is dispatched to our premises.
Fax or post a completed copy of the health and safety clearance form to us in advance.
The declaration must arrive before the equipment. Enclose a second completed copy
with the product. If the equipment is contaminated you must notify the carrier.
No repair / DKD calibration is possible unless the correctly completed form is
returned. Inevitably, there will be a delay in processing the equipment if information is missing or if this procedure is not complied with.
If the product has come in contact with chemicals, radioactive substances or other
substances dangerous to health or environment, the product must be decontaminated
prior to sending it back to the factory.
☞ Return the product to us disassembled and cleaned and accompanied by a cer-
tificate verifying decontamination or
☞ Contact an industrial cleaning and decontamination service directly or
☞ Authorize us to send the product to an industrial cleaning facility at your expense.
To expedite repair and to reduce costs, please enclose a detailed description of the
problem and the product´s operating conditions with every product returned for repair.
We submit quotations only on request and always at the customer´s expense. If an
order is given, the costs incurred are offset from the costs for repair or from the purchase price, if the customer prefers to buy a new product instead of repairing the
defective one.
☞☞
☞ If you do not wish a repair on the basis of our quotation, the equipment might
☞☞
be returned to you disassembled and at your charge!
In many cases, the components must be cleaned in the factory prior to repair.
For cleaning we use an environmentally responsible water based process. Unfortunately the combined attack of elevated temperature, cleaning agent, ultrasonic treatment and mechanical stress (from pressurised water) may result in damage to the
paint. Please mark in the health and safety clearance form if you wish a repaint at
your expense just in case such a damage should occur.
We also replace parts due to optical aspects upon your request.
Before returning the equipment ensure that (if applicable):
☞ Oil has been drained and an adequate quantity of fresh oil has been filled in to
protect against corrosion.
☞ Equipment has been cleaned and/or decontaminated.
☞ All inlet and outlet ports have been sealed.
☞ Equipment has been properly packed, if necessary, please order an original pack-
aging (costs will be charged), marked as appropriate and the carrier has been notified.
☞ Ensure that the completed health and safety declaration is enclosed.
We hope for your understanding for these measures, which are beyond our control.
Scrapping and waste disposal:
Dispose of the equipment and any components removed from it safely in accordance
with all local and national safety and environmental requirements. Particular care must
be taken with components and waste oil which have been contaminated with dangerous substances from the process. Do not incinerate fluoroelastomer seals and “O“
rings.
☞ You may authorize us to dispose of the equipment at your expense.
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.: 999100 / 06/05/2008
