Dear customer,
Your VACUUBRAND pumps are designed to provide you with many years
of trouble-free service with optimal performance. Through our long experience in design, construction and operation of vacuum pumps, combined
with the latest developments in material and manufacturing technology,
we have accumulated a wealth of application and safety insights that we
want to share with you.
Please read these instructions for use before the initial operation of your
pump.
Our quality maxim is the ”zero fault principle”:
Every pump, before leaving our factory, is tested intensively, including an
endurance run of 60 hours. Any faults, even those which occur rarely, are
identified and can be eliminated immediately.
After completion of the endurance run, every pump is tested, and must
achieve specifications 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

Setting up and installing the equipment
➨ Equipment must be connected only to a suitable electrical 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.
The supply cable may be fitted with a molded European 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 generate 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 tubing 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!
☞Keep the electrical power cord away from heated surfaces.
• Provide a firm, level platform for the equipment. Check
that the system which you are going to evacuate is
mechanically stable. Check that all fittings are secure.
Ensure a stable position of the pump without any mechanical contact other than the pump feet.
• Comply with maximum permissible pressures at inlet and outlet and with maximum permissible pressure differences between inlet and outlet. See section
“Technical data”, pg. 19. Do not operate the pump
with overpressure at the inlet.
• Avoid overpressure of more than 17.5 psi absolute (1.2
bar absolute) in the event that gas or inert gas is con-
page 10 of 60
nected to the pump, to the gas ballast or to a venting
valve.
• Note: Flexible elements will shrink when evacuated.
• Connect hoses gas tight at inlet and outlet of the pump.
• 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.
• Use only oil of the recommended type. Other oils or
operating fluids may cause damage of the pump or
danger.
Use special oils (see “Oil change”, pg. 35) for the
rotary vane pump, if, e.g.,
- acid vapors are pumped.
- extremely high aging stability is required.
- oxygen or other strong oxidizing agents are pumped.
• Take adequate precautions when handling pump fluids, lubricants, and solvents. Use appropriate protective clothing, safety goggles and protective gloves to
avoid excessive contact with the skin and possible
skin irritations (including dermatitis). Do not inhale or
swallow! Ensure that the pump location is well ventilated and that possible toxic effects of certain vapors
are avoided. Maintain adequate levels of hygiene and
cleanliness.
• Comply with all relevant statutory requirements and
regulations concerning the handling, storage and disposal of oil.
Note: Do not allow oils to enter the drainage system
or other bodies of water. Spillage can cause accidents
(slip hazard)!
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
page 11 of 60
(e.g., housing, walls, etc.), or else install an external automatic ventilation system. Check fan regularly for dust/
dirt. Clean fan guard if necessary to avoid a reduction of
ventilation.
The On/Off switch is located at the side of the terminal
box.
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 connections (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 requirements (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 flames.
page 12 of 60
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. 19).
Operating conditions
➨These pumps are not approved for operation in potentially explosive atmospheres. Do not operate the
pumps in potentially explosive atmospheres.
➨These pumps are not approved for the pumping of potentially explosive atmospheres. Do not pump potentially explosive atmospheres.
➨The pumps are not suitable to pump any of the substances 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,
- self inflammable substances,
- substances which are inflammable 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 deposits 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. Deposits may cause seizing of the pump unit.
page 13 of 60
• Check the inlet and outlet of the pump and its oil condition, if there is a danger of forming deposits inside the
pump, e.g., in the pump unit of the rotary vane pump or
in the pump chamber of the diaphragm pump. Inspect
the pump regularly and clean if necessary.
• Install a cold trap in front of the pump if pumping aggressive or corrosive gases or vapors.
• 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. 19.
When changing the substances pumped, we recommend 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 dangerous, toxic, explosive, corrosive, noxious or polluting fluids, 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 formation of explosive mixtures in the expansion chamber, in the oil reservoir, in the pump chamber of the
diaphragm pump, 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 gas ballast or venting, if necessary.
➨Drain appropriately or otherwise remove any poten-
page 14 of 60
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.
+Always provide a free and pressureless exhaust outlet. Make sure that the exhaust tubing cannot become
blocked. Do not exceed an pressure of 16 psi (1.1 bar)
in the exhaust tubing.
+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, oil mist, thermal decomposition products
of fluoroelastomers). Use appropriate protective clothing and safety goggles.
+Even if the pumped medium is only air or a pure gas,
the discharge from rotary vane pumps will contain small
quantities of oil vapor and petroleum fractions. These
substances are particularly contaminating in closed
spaces or in case of insufficient ventilation.
The discharge from the pump invariably contains the
pumped gases or vapors! Connect a hose to the pump
outlet to dispose of the exhaust gases.
Prevent any dangerous reactions with oil or oil vapors
and the formation of impermissible or dangerous emissions.
+Failure of the pump (e.g., due to power interruption),
failure of connected components or of parts of the supply, or a change of parameters must not be allowed to
lead to a dangerous situation under any circumstances.
page 15 of 60
In case of a leak in the manifold or at the shaft seal of
the rotary vane pump, or in case of a diaphragm crack
of the diaphragm pump, pumped substances might be
released into the environment or into the pump housing or motor.
Especially comply with notes on use and operation and
maintenance.
+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 fingers
can be caught or drawn in at the inlet of the pump.
Never insert fingers or drop any other object into the
inlet or outlet.
• Pumping at high inlet pressure may lead to overpressure at the gas ballast valve. Pumped gases or condensate might be expelled if the valve is open. If an inert gas supply is connected to the gas ballast, ensure
that its inlet pipeline is not contaminated.
• Check oil level of the rotary vane pump (through sight
glass) every time before starting the pump.
• Check the pump’s oil level and the condition of the oil
on a regular basis.
• 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.
• A power failure or switching off the pump may cause
accidental ventilation of the pump or the vacuum system, if the manual gas ballast valve of the rotary vane
page 16 of 60
pump is open. If this constitutes a potential source of
danger, take appropriate safety measures, e.g., install
a solenoid operated gas ballast valve.
NOTICE
Prevent the backpressure of gases and the backflow of
condensates at the outlet.
Important notes on working with condensable vapors:
Allow the pump to attain its operating temperature before
pumping condensable vapors. Keep the vapor inlet pressure below the permitted maximum (see ”Technical data”,
pg. 19).
Open the gas ballast valve in case of pumping significant
amounts of vapor.
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. Switch off the pump
and disconnect from the power source. Identify and eliminate the cause of failure. Wait approx. five minutes before
restarting the pump.
Maintenance and repair
NOTICE
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. 53”, pg. 53) are followed.
Take advantage of our service seminars, which put special
focus on the maintenance and repair of vacuum pumps.
page 17 of 60
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. Motor capacitors have a typical durability in the range of 10000 to 40000 h depending
strongly on operation conditions, including ambient temperature, humidity or load.
➨Ensure that the pump cannot be operated accidentally. 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 five seconds 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
before maintenance commences. Avoid the release of
pollutants.
☞Take adequate precautions to protect people from the
effects (e.g., in case of inhalation or skin contact) 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.
+Check every motor capacitor regularly by measuring
its capacity and estimating its time in operation. Replace old capacitors early enough to prevent a failure
in operation. If an old motor capacitor fails, the capacitor may get hot. It may even melt or emit a flame, which
could be dangerous for persons and equipment in
the vicinity. The capacitors have to be replaced by an
page 18 of 60
electrician.
+Vent the pump before starting maintenance. Isolate the
pump and other components from the vacuum system.
Allow sufficient cooling of the pump. Drain condensate,
if applicable.
NOTICE
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.

a.) Partial pressure of permanent gases measured at pump inlet.
b.) The total pressure is higher than the partial pressure because the former includes the vapor
pressure of the pump oil and other condensable vapors (e.g., water); the condition of the oil
(cleanliness, content of hydrocarbons with higher partial pressures) is crucial for this value.
c.) The maximum inlet pressure for water vapor, or rather the maximum inlet pressure for vapor,
cannot be specified in accordance with ISO 21360-2 because it cannot be determined for the
HYBRID pump in accordance with this standard. Because the diaphragm pump reduces the
pressure in the oil-sealed part of the RC 6, however, the water vapor tolerance is considerably
higher than that of a conventional oil-sealed rotary-vane pump.
d.) With inlet sealed and without gas ballast.
e.) Oil temperature and pressure in the oil reservoir are the relevant parameters for maximum

Use and operation
Method of operation:
The RC 6 is a four-stage vacuum pump consisting of an oil-sealed, twostage rotary vane pump with a series-connected two-stage diaphragm
pump. The two units are mounted on a common shaft and are connected
directly to the drive motor. The dry-running compressor-type diaphragm
pump evacuates the headspace of the oil reservoir of the rotary vane
pump, thus considerably increasing the latter’s maximum vapor inlet
pressure and chemical resistance.
With the gas ballast valve closed, the rotary vane pump shuts off vacuum
tight. This, in turn, prolongs the intervals between oil changes and improves corrosion resistance. The oil system incorporates an oil pump;
this forced-lubrication system ensures an adequate supply of oil to the
pump unit even at high inlet pressures. A mechanical retaining valve in
the oil system prevents oil suck-back into the vacuum system.
The oil mist filter of the rotary vane pump removes 99 % of the oil mist. If
an exhaust waste vapor condenser is fitted (available on request), the vapors handled by the pump can be condensed to a large extent and either
be recycled or disposed of in accordance with regulations.
page 24 of 60
Initial operation / Pouring in the pump oil
• The pump is supplied dry (i.e., without oil filling).
This is in order to ensure that oil cannot make its way
from the rotary vane pump into the housing of the oil
mist filter during transport. A can containing 0.5 liter
(0.53 quarts) of rotary-pump oil is supplied with the
pump. Before starting the pump for the first time,
pour in the oil as described below.
Pouring in the oil:
(A)
(B)
➨Remove the oil inlet plug (A) (6 mm
wide Allen key).
☞Note: Because new oil contains
gas, a considerable degree of foaming can occur during operation with
new oil, and oil could penetrate the
oil separator.
➨Pour only approx. 350 ml (0.37 quarts) of oil into the
pump (bringing oil level to ”min.” mark (B), approx.).
➨Screw in oil inlet plug and with inlet line closed, operate the pump for approx. 5-10 minutes.
➨Remove the oil inlet plug again.
➨Add approx. 100 ml (0.11 quarts) of oil.
☞As a rule, it is not necessary to use all of the oil supplied. Do not overfill!
(C)
➨ Screw in the manometer (C) with its
adapter carefully (open end wrench
width 17 mm).
☞Pay attention to the O-ring!

Installing a pump in a vacuum system
➨If dangerous or polluting fluids, oil mist, or toxic or noxious gases could be released at the outlet, install an
appropriate system to catch and dispose of those fluids or gases.
+Connect a gas-tight exhaust line at the pump outlet if
necessary. Always vent exhaust gases appropriately
(e.g., into a fume hood). If needed, install an exhaust
waste vapor condenser (see ”Accessories”, pg. 39).
+Never block the gas outlet. The exhaust line must always 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.
+ Failure to connect the inlet and outlet lines correctly
will cause overpressure and risk of bursting! The outlet
(hose nozzle) is marked ”EX”.
+Particles and dust must not be aspirated. If necessary,
you must install appropriate filters. You must ensure
their suitability concerning gas flow, chemical resistance 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.
• Reduce the transmission of vibration. Prevent mechanical load due to rigid pipelines. Insert elastic hoses or
flexible elements as couplings between the pump and
rigid pipes.
Note: Flexible elements will compress or flatten when
evacuated if not designed for use under vacuum.
• Hose connections at the pump inlet must always be
gas tight.
page 26 of 60
• Install a cold trap in front of the pump, if pumping aggressive or corrosive gases or vapors.
• A power failure may cause accidental ventilation of the
pump or the vacuum system, if the manual gas ballast
valve is open. If this constitutes a potential source of
danger, take appropriate safety measures, e.g., install
a solenoid operated gas ballast valve (see “Accessories”, pg. 39).
• The pump is supplied dry (i.e., without oil filling).
Before starting the pump for the first time, pour in
the oil as described in the above section ”Initial operation / Pouring in the pump oil”, pg. 24.
• 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
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 flow losses. Locate the pump
as closely as possible to the application. 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 connections.
Always install outlet tubing descending from the pump or
provide other measures to avoid backflow of condensate
towards the pump.
Use a suitable valve (see”Accessories”, pg. 39) 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.
page 27 of 60
Secure hose connections at the pump appropriately, e.g.,
with hose clamps, to protect against accidental detachment.
Note: The pump must only be operated in a horizontal
position. When transporting a pump containing oil, take
great care not to tilt the pump to an angle that would allow
oil to make its way into the filter element.
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.
• 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 overheating due to insufficient cooling.
• Check compatibility with the maximally permitted
pressures at inlet and outlet and the maximum pressure difference between inlet and outlet ports.
• Check the oil level of the rotary vane pump every time
before starting the pump, however at least once a week.
page 28 of 60
Check the oil level more frequently if high amounts of
gas or vapor are pumped.
• If pumping aggressive, corrosive or otherwise dangerous gases and vapors, take appropriate measures to
protect personnel, pump, and environment. Use appropriate equipment such as cold trap, separator, oil
separator, full flow oil filter, shut-off valve, or exhaust
waste vapor condenser (see “Accessories”, pg. 39)
as well as special oil.
NOTICE
The ambient temperature should be at least 54°F (12
°C). Otherwise the pump may not start because of the
high oil viscosity at low temperature.
Pumping down can be started at any pressure at the inlet
below atmospheric pressure.
Do not start the pump if the pressure at the outlet port
exceeds 16.0 psi (1.1 bar) absolute.
Continuous operation is possible at any pressure below
atmospheric pressure.
Oil consumption will increase at inlet pressures above 75
Torr (100 mbar). Check oil level more frequently.
Prevent internal condensation, transfer of liquids or dust.
The pump unit as well as the diaphragms and valves will
be damaged if liquids are pumped in significant 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.
The motor is protected by a self-hold thermal cutout in
the winding.
Note: Only a manual reset is possible. Switch off the
pump and disconnect the electrical power cord. Identify
and eliminate the cause of failure. Wait approximately five
minutes before restarting the pump.
page 29 of 60
Avoid high heat supply (e.g., due to hot process gases).
See “Technical data”, pg. 19, for maximum permitted
gas and ambient temperatures.
A warm up period (approximately 30 min.) is required to
ensure that the rated ultimate vacuum and pumping speed
as well as the full vapor pumping rate and chemical resistance of the pump are attained. To warm up the pump
effectively before connecting to the vacuum application,
install a shut-off valve (see ”Accessories”, pg. 39).
The attainable ultimate vacuum is limited by the properties
of the vacuum vessel (leak-tightness, cleanliness and degassing of the inner surfaces), degassing of substances
used and the condition of the pump oil (cleanliness, content of hydrocarbons with higher partial pressures).
Use the manometer monitoring the pressure in the oil
reservoir of the HYBRID pump to check the operability of
the diaphragm pump. If during the process the pressure
inside the oil reservoir should rise significantly (manometer needle clearly in the red zone), it is necessary to take
appropriate measures to reduce the inlet pressure.
For the HYBRID principle to work it is necessary to
prevent the pumped vapors from condensing inside
the oil reservoir. Therefore the pressure inside the
oil reservoir has to be lower than the vapor pressure
of the pumped media at the oil’s temperature (140°F
(60°C)). If necessary, the volume of pumped vapors
has to be reduced or a cold trap has to be installed.
If no improvement is achieved even with the vacuum
chamber being absolutely leak tight, this points to a potential failure of the diaphragm pump, e.g., a diaphragm
crack. A more accurate check of the pressure inside the oil
reservoir is possible with a more precise manometer, e.g.,
a DVR 2 digital vacuum gauge. If a pressure higher than
19 Torr (25 mbar) is measured with inlet port and gas ballast valve closed, check the diaphragm pump and replace
the diaphragms if necessary.
Any drop in the diaphragm pump’s pumping speed produces a pressure increase in the oil reservoir. Although
page 30 of 60
this does not have a direct effect on the pumping speed
and on the ultimate vacuum attainable by the HYBRID
pump, it does have a considerable effect on the aging of
the oil and the HYBRID pump’s chemical resistance.
All bearings are encapsulated and are filled with long-life
lubricant. Under normal operating conditions, the drive
system is maintenance free. The valves and diaphragms
are wear parts. Aging of the oil of the rotary vane pump
necessitates oil changes.
Important notes regarding the use of gas ballast
Gas ballast is a continuous purge to keep the pump’s interior as clean as possible and to reduce the possibility of
condensation inside the pump.
➨Air and pumped media might react inside the pump or
at the outlet of the pump and form hazardous or explosive mixtures, when you use air rather than inert gas
for the gas ballast. This constitutes a risk of significant
damage to equipment and/or facilities, a risk of personal injury or even loss of life.
+Make sure that air/gas intake through the gas ballast
valve can never lead to hazardous, explosive or otherwise dangerous mixtures. If in doubt, use inert gas.
NOTICE
To reduce condensation in the pump, do not pump vapor
before the pump has reached its operating temperature.
Open the gas ballast valve when pumping condensable
vapors.
page 31 of 60
gas ballast
(open)
For condensable vapors (water vapor, solvents, etc.):
- Let the pump run with gas ballast to reduce condensation of pumped substances
(water vapor, solvents, ....) in the pump or
to decontaminate the pump oil from volatile
substances.
- With gas ballast valve open, the ultimate vacuum will
be reduced.
- Use inert gas for gas ballast to avoid the formation of
explosive mixtures.
- To open and to close the gas ballast valve turn the
gas ballast valve cap. The manual gas ballast valve
is open if the arrow on the gas ballast cap is pointing
towards the inlet of the pump respectively towards the
labelling ”Gasballast”.
- Close the manual gas ballast valve by turning the cap
180°.
Operate the pump without gas ballast only in case of
a clean system or when there are no condensable vapors.
NOTICE
Do not pump vapors until the pump has reached its operating temperature. Install an in-line valve in the inlet line
and open it only approx. 30 minutes after the pump has
been started.
Check the maximum vapor inlet pressure. The pump can
operate continuously at any pressure lower than the maximum specified inlet pressure for vapor. Avoid sudden vapor surges when evacuating commences (large inner surfaces, large-volume vacuum vessel).
Use a flow-control valve in the inlet line and open the valve
gradually.
page 32 of 60
Operating the pump with condensate in the
catchpots
NOTICE
Observe the condensate levels in the catchpots of the separator at the inlet and of the oil mist filter. The condensate
level in an optional separator at the inlet must always be
kept below the bottom of the separator tube. The condensate level in the oil mist filter must always be kept below
the bottom edge of the filter.
Drain condensate in time. To drain condensate, switch off
and vent the pump. Then open drain screw of the catchpot. Condensate of the inlet catchpot (see ”Accessories”,
pg. 39) in particular must not be drained while pump is
operating.
In case of a clogged filter, oil mist might be visible in the
oil filter housing, or the filter might be discolored or exhibit
deposits on the inside. If the filter element is clogged, disassemble the oil mist filter and replace the filter element.
Under certain circumstances, clogged filter elements can
be cleaned using suitable solvents. However, it is safer to
use a new filter element (see section ”Replacing the filter
element in the oil mist filter”, pg. 52).
Do not reuse separated oil if it is contaminated or discolored.
☞Important: Comply with regulations when disposing
of solvents/condensates. Recycle if possible; purify if
contaminated.
page 33 of 60
Pumping chemically aggressive or toxic gases and vapors
➨Avoid explosive conditions when compressing explosible and flammable substances/mixtures. In such instances, use inert gas for gas ballast.
Attention: The gas ballast of the diaphragm pump is
permanently connected to the system.
☞ Implement special protective measures to protect personnel, pump, and environment.
• Install a cold trap (see ”Accessories”, pg. 39), if the
thermodynamic conditions of the application are such
that vapors could condense in the rotary vane pump.
Wait until the pump has reached its operating temperature before connecting it to the vacuum system.
NOTICE
Before switching off, allow the pump to run for a few minutes, initially with the rotary vane pump‘s gas ballast valve
open and then with the gas ballast valve closed, after the
pump has been isolated from the vacuum application.
Prevent internal condensation, transfer of liquids or dust.
The pump requires regular inspection and maintenance.
page 34 of 60
Shutdown
NOTICE
Has the pump been exposed to condensate?
- Allow the pump to continue to run for a few minutes
with the rotary vane pump’s gas ballast valve open before switching off.
Long-term:
- Separate the pump from the application.
- Drain condensates (catchpots of the separator at the
inlet and of the oil mist filter).
- Flush the pump with dry nitrogen.
- Carry out oil change (see “Oil change”, pg. 35).
- Fill the pump completely with new oil (to above the
”max.” mark!).
Attention: Before restarting the pump, drain oil to the
maximum oil level (”max.” mark)!
- Close the manual gas ballast valve.
- Close inlet and outlet ports (e.g., with transport caps or
blind flanges).
- Store the pump under dry conditions.
- Carry out oil change and maintenance prior to use if
the pump has been stored for longer than one year.
Note: When transporting a pump containing oil, take great
care not to tilt the pump to an angle that would allow oil to
make its way into the filter element. Drain oil if necessary.
page 35 of 60
Oil change
➨Never operate the pump if parts of the pump are disassembled. Ensure that the pump cannot be operated
­accidentally.
➨ Before starting maintenance, isolate the pump from its
application and disconnect the electrical power cord.
➨Note: The pump or the pump oil might be contaminated
with dangerous or corrosive process chemicals that
have been pumped during operation. Adopt suitable
decontamination measures if necessary. 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.
☞Use appropriate protective clothing, safety goggles
and protective gloves. Avoid inhalation and skin contact.
• Take adequate precautions when handling pump fluids, lubricants, and solvents. Use appropriate protective
clothing, safety goggles and protective gloves to avoid
excessive contact with the skin and possible skin irritations (including dermatitis).
Comply with all relevant statutory requirements and
regulations concerning the handling, storage and disposal of oil.
NOTICE
Aging of the oil (as indicated by darker color compared to
new oil, strange odor of the oil, particles in the oil, or contamination) necessitates an oil change.
Depending on the application (especially if corrosive gases or vapors have been pumped) it may be appropriate to
check the oil frequently and to carry out an oil change, if
necessary.
page 36 of 60
Under normal operating conditions:
- Check oil level every time before starting the pump.
- Carry out an oil change once aging of the oil is indicated by darker color compared to new oil.
- Carry out oil changes at least once a year.
- Dispose of the used oil, which may be contaminated,
according to all applicable regulations.
If the oil contains small quantities of water/solvent:
☞ The oil can be cleaned to a certain extent by operating
the pump for 1 - 2 hours with the inlet line sealed and
the gas ballast valve open.
Oil change procedure
☞Carry out the oil change only after the pump has
reached its normal operating temperature.
➨Switch off the pump and isolate it from its application.
Ventilate the pump to atmospheric pressure. Disconnect the electrical power cord. To vent the oil reservoir,
remove the manometer with its adapter carefully (open
end wrench width 17 mm). Pay attention to the O-ring!
Do not turn the manometer itself as leaks might be
caused!
☞Choose a suitable pad; oil may drip. Use a suitable
container to catch the oil.
(1)
(8)
(10)
(9)
➨ Place a suitable container below the oil outlet (9).
➨ Remove the oil drain plug (9) below the rating plate, paying attention to the O-ring.
➨Tilt the pump slightly and catch the oil in a
suitable container.
☞Dispose of the used oil according to regulations.
➨Screw in oil drain plug (9) with O-ring.
➨Screw in manometer with O-ring.
➨To flush the pump, pour in fresh oil (approx. 0.05 quarts
(50 ml)) through the pump inlet (1) (remove separator
if necessary).
page 37 of 60
➨Operate the pump briefly. Drain flushing oil and repeat
flushing procedure, if necessary, until all contaminations are flushed out.
➨Remove the manometer (see above). Add fresh oil (at
first approx. 0.37 quarts (350 ml) only) through the oil
inlet port for the oil level to reach the ”min.” mark (10).
➨Close the oil inlet port (8). Operate the pump with
closed inlet for approx. 5-10 minutes.
➨Top off the oil (add approx. 0.11 quarts (100 ml)). As a
rule, it is not necessary to use the maximum quantity
of oil. Do not overfill!
➨Screw in manometer with O-ring.
Note: The oil degasses and foams at low pressures. This
is a welcome condition which helps to protect the pump
against corrosion and to prolong the working life of the oil.
The quantity, condition and quality of the pump oil have a
decisive effect on the pump’s performance and dependability.
Important: It may not be possible to reach the specified
ultimate vacuum if an oil other than VACUUBRAND B-oil
is used. Similarly, failure to use the recommended oil may
impair cold-start performance and pump lubrication!
Notes on choosing the appropriate oil for the application
The standard oil for VACUUBRAND rotary vane pumps is the B-oil. This
is a mineral oil, which is used for the first filling of the pump.
The advantages of the B-oil are: Flat viscosity curve, low vapor pressure,
good chemical resistance, extended stability when pumping oxidants,
acid or basic vapors compared to conventional mineral oils, and good
skin compatibility.
Certain pumped media may attack the conventional oil in the pump. Special oils can be used preventively. It is at the users’ responsibility to check
if the materials of the wetted parts are resistant against the pumped substances. This is also mandatory if special oils are used.
page 38 of 60
Special oils:
Rotary vane pump oil K8
The rotary vane pump oil K8 is a special oil designed for pumping acid
vapors. The oil is very hygroscopic and has a limited capacity for acids.
With decreasing pH, the anticorrosive effect decreases as well, and it is
necessary to change the oil at appropriate intervals. When the pump will
stand still for prolonged periods (i.e., for several days), the oil must be
drained and the pump must be filled with mineral oil.
Synthetic oil (perfluoropolyether oil, e.g., Fomblin®*)
Synthetic oils have an excellent chemical resistance and are certified
for pumping pure oxygen. Therefore these oils are excellent for handling
strong oxidants, e.g., halogens, nitrogen oxides, etc.
Attention: As perfluoropolyether oils mixed with mineral oils result in an
emulsion, pumps used with these oils must be absolutely free of any
residues of mineral oils. To accomplish this, you must completely disassemble and diligently clean the pump unit.
* reg. trade mark Montedison
Attention if using special oils: Due to a different viscosity / density compared to the standard oil, pumps filled with special oil may not achieve
the specified ultimate pressure, or the pumps may not start reliably at
temperatures below 54°F (12°C).

Replacing diaphragms and valves
☞Please read section ”Replacing diaphragms and valves” completely 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 electrical power cord. Wait five seconds 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 process 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 (e.g., in case of inhalation or skin contact) 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.
+ Check every motor capacitor regularly by measuring
its capacity and estimating its service life. Replace old
capacitors early enough to prevent a failure. The capacitors must be replaced by a trained electrician.
+ Allow sufficient cooling of the pump before starting
maintenance. Drain condensate, if applicable.
+ Vent the pump and isolate it from the vacuum system before you start maintenance.
page 45 of 60
NOTICE
Ensure that maintenance is done only by suitably
trained and supervised technicians.
The valves and diaphragms as well as the motor capacitors are wear parts. At the latest if the pressure inside the
oil reservoir should rise significantly (manometer needle
clearly in the red zone), 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 filled with long-life
lubricant. Under normal operating conditions, the drive
system is maintenance free.
The operability of the diaphragm pump can be checked as
well by measuring the pressure in the oil reservoir:
➨Unscrew the manometer with its adapter (open end
wrench width 17 mm). Remove the hose nozzle from
the distributor plate (outlet) and install at the oil inlet.
Make sure the O-ring is seated correctly.
➨Using a suitable vacuum gauge (e.g., DVR 2) and
making sure that it is correctly calibrated, measure the
pressure in the oil reservoir. When the pump operates
with the inlet line closed, the measured pressure in the
oil reservoir should be less than 25 mbar (19 Torr) (with
gas ballast valve of rotary vane pump closed).
➨Remove the hose nozzle from oil inlet. Reinstall it in
the distributor plate and reassemble the manometer
with O-ring.
In demanding circumstances, it may be efficient 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 significant 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.

Cleaning and inspecting the diaphragm pump heads
➨ Drain the catch pot of the oil mist filter before beginning maintenance
to prevent leaking of condensate!
➨Drain oil (see ” Oil change”) to prevent oil from making its way into the
filter element. Refill pump with oil before restarting the pump!
➨For maintenance, lay the pump on its side with the pump head to be
maintained at the top. Support the pump appropriately.
Attention: Prevent any damage to the oil mist filter or to the manometer. Do not use the oil mist filter to prop up the pump.

➨Turn the fittings with an open-ended wrench
(14 mm) to detach the hoses from the pump
heads (1/4 of a turn at maximum).
+Do not remove the elbow fittings from the
pump heads; during reassembly a leak may
result.
page 48 of 60
➨Disassemble the housing cover to check
the diaphragm and the valves.
➨Unscrew four Allen screws with a 5 mm
wide Allen key. Remove the housing cover
with housing cover insert together with the
head cover and the valves (head cover with
valves will remain within the housing cover).
+ Never remove parts by using a pointed or sharp-edged tool (e.g., screw
driver). We recommend to use a rubber mallet or compressed air (to
be blown carefully into port).
➨Remove the head cover carefully from the housing cover. Note the
position and orientation of the valves and remove them.
+Replace valves if necessary.
+Check diaphragm for damage and replace if necessary.
+Use petroleum ether or industrial solvent to remove deposits. Do not
inhale vapors.
Replacing the diaphragm
➨Lift diaphragm carefully sidewise.
+Never use a pointed or sharp-edged tool to
lift the diaphragm.
➨Use the diaphragm key to grip the diaphragm support disc below the diaphragm.
➨Unscrew diaphragm support disc with diaphragm and diaphragm clamping disc.
☞If the old diaphragm is difficult to separate from the diaphragm support
disc, immerse assembly in naphtha or petroleum ether. Do not inhale
vapors!
➨Check for washers between the diaphragm support disc and the connecting rod. 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.
page 49 of 60
☞Too few washers: The pump will not attain vacuum specification. Too
many washers: Diaphragm clamping disc will hit head cover, causing
noisy operation and possibly causing the pump to seize up.
➨
Position new diaphragm between diaphragm clamping disc with square head
screw and diaphragm support disc.
☞Note: Position diaphragm with pale side
towards diaphragm clamping disc (facing
pump chamber).
☞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
between diaphragm support disc and connecting rod.
➨Screw diaphragm clamping disc , diaphragm, diaphragm support disc, and washers to connecting rod.
➨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.
page 50 of 60
Assembling the pump heads
➨ Bring the diaphragm into a position, in which
it is in contact with the housing and centered
with respect to the bore.
➨Place the head cover over the diaphragm. Check for its correct orientation by aligning it beforehand with the housing cover which has to be
put over it later on.
+Pay attention that the diaphragm stays positioned centrally so that it
will become clamped uniformly between housing and head cover.
➨Place the valves at their respective positions on the head cover.
+Make sure that the valves are correctly
seated. See figure for the correct position of
the valves: Valves at the outlet with round
centered opening (A) under valve; valves
at the inlet with kidney-shaped opening (B)
beside valve.
➨ Place the housing cover with housing cover insert onto the head cover.
➨By turning the eccentric bushing, bring the connecting rod into the upper turning point position (max. stroke of the rod).
A
B
➨Loosely screw in the Allen head screws at
the head cover diagonally at first slightly
with a 5 mm wide Allen key, then tighten.
☞Recommended torque: 8.9 ft.lbf (12 Nm).
page 51 of 60
Assembling the connecting hose
➨Slip the hoses onto the hose connectors by
turning the fittings with an open-ended 14
mm wrench.
➨Tighten the union nuts of the hose connections at the pump heads with an open-ended 17 mm wrench.
+Tighten union nuts first by hand and then
tighten one full turn using the open ended
wrench.
Replace diaphragm and valves of the opposite side of the
pump in the same way.
➨ Assemble the cover plate. Pay attention to lock washers. Put the pump
in normal operating position.
☞Attention: Make sure that the pump is filled with oil before switching it
on, refill oil if necessary (see ”Oil change”, pg. 35)!
Checking the operability of the diaphragm pump
Check the operability of the diaphragm pump by measuring the pressure
in the oil reservoir:
➨Unscrew the manometer with its adapter (open end wrench width 17
mm). Remove the hose nozzle from the distributor plate (outlet) and
install at the oil inlet. Make sure the O-ring is seated correctly.
➨Using a suitable vacuum gauge (e.g., DVR 2) and making sure that it
is correctly calibrated, measure the pressure in the oil reservoir. When
the pump operates with the inlet line closed, the measured pressure in
the oil reservoir should be less than 25 mbar (19 Torr) (with gas ballast
valve of rotary vane pump closed).
➨Remove the hose nozzle from oil inlet. Reinstall it in the distributor
plate and reassemble the manometer with O-ring.
page 52 of 60
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 specified ultimate vacuum is not achieved, and if this does not
change after the break-in period:
Check hose connectors at pump heads for leaks. If necessary recheck
valve seats and pump chambers.
Replacing the filter element in the oil mist filter
Filter element FO DN 10 ..............................................................................640187
➨Use a 5 mm wide Allen key to remove the drain plug (note O-ring fitted
on drain plug). Drain condensate from catchpot.
➨ Position the pump on the side so that it rests on the side with the power
switch. Remove the Allen screws (5 mm wide Allen key) and remove
the catchpot (note sealing ring).
➨Using a 5 mm wide Allen key, remove the Allen screw in the center
of the bottom filter thrust plate. Remove the filter element, both filter
thrust plates, and the top O-ring.
☞Clean or replace the filter element. Dispose of oil and filter element in
accordance with regulations.
➨Assemble again in reverse order. Make sure that the O-ring and the
sealing ring are correctly seated.
