Product Description
Use
The vacuum pump is intended for
the suction
of
air and other dry, non-aggressive, non-toxic and non-explosive
gases
Conveying media with a lower or higher density than air leads to an in
-
creased thermal and/or mechanical load on the vacuum pump and is
permissible only after prior consultation with Busch.
In case the vacuum pump is equipped with a gas ballast (optional) wa-
ter vapour within the gas flow can be tolerated within certain limits
(
page 8: Conveying Condensable Vapours). The conveyance of
other vapours shall be agreed upon with Busch.
The vacuum pump is intended for the placement in a non-potentially
explosive environment.
Version with oil return line to the suction connection (RC 0006 C/E):
The vacuum pump is thermally suitable for continuous operation
(100 percent duty).
Version with oil return valve (RB 0006 C/E):
The vacuum pump is thermally suitable for continuous operation (ob
-
serve the notes with regard to the oil recirculation:
page 3: Oil Cir
-
culation;
page 8: Oil Return).
The vacuum pump is ultimate pressure proof.
Principle of Operation
The vacuum pump works on the rotating vane principle.
A circular rotor is positioned centrically on the shaft of the vacuum
pump (i.e. drive motor shaft).
The rotor rotates in an also circular, fixed cylinder, the centreline of
which is offset from the centreline of the rotor such that the rotor and
the inner wall of the cylinder almost touch along a line. Vanes, sliding
in slots in the rotor, separate the space between the rotor and the cyl
-
inder into chambers. At any time gas is sucked in and at almost any
time ejected. Therefore the vacuum pump works almost pulsation free.
In order to avoid the suction of solids, the vacuum pump is equipped
with a screen in the suction connection.
In order to avoid reverse rotation after switching off, the vacuum
pump is equipped with a non-return valve.
Note: This valve shall not be used as a non-return valve or shut-off
valve to the vacuum system and is no reliable means to prevent suction
of oil into the vacuum system while the vacuum pump is shut down.
In case the vacuum pump is equipped with a gas ballast (optional):
Through the gas ballast a small amount of ambient air is sucked into
the pump chamber and compressed together with the process gas. This
counteracts the accumulation of condensates from the process gas in
-
side the vacuum pump (
page 8: Conveying Condensable Vapours).
The gas ballast line is equipped with a paper filter.
Oil Circulation
The vacuum pump requires oil to seal the gaps, to lubricate the vanes
and to carry away compression heat.
The oil reservoir is located on the pressure side of the vacuum pump
(i.e. high pressure) at the bottom of the bottom chamber of the oil
separator (f).
The feed openings are located on the suction side of the vacuum pump
(i.e. low pressure).
Forced by the pressure difference between pressure side and suction
side oil is being drawn from the oil separator (f) through the oil supply
lines and injected on the suction side.
Together with the sucked gas the injected oil gets conveyed through
the vacuum pump and ejected into the oil separator (f) as oil mist. Oil
that separates before the exhaust filter accumulates at the bottom of
the bottom chamber of the oil separator (f).
Oil that is separated by the exhaust filter accumulates at the bottom of
the upper chamber of the oil separator (f).
The flow resistance of the exhaust filters causes the inside of the ex
-
haust filters (which is connected to the bottom chamber of the oil sep
-
arator) to be on a higher pressure level than the outside of the exhaust
filters (i.e. the upper chamber of the oil separator). Because of the
higher pressure in the bottom chamber it is not possible to let oil that
drips off the exhaust filters simply flow down to the bottom chamber.
Version with oil return line to the suction connection (RC 0006 C/E):
Therefore the oil that accumulates in the upper chamber is sucked
through the oil return line right to the suction connection.
Version with oil return valve (RB 0006 C/E):
At continuous operation this would cause the entire supply of oil to ac
-
cumulate at the bottom of the upper chamber, expel oil droplets
through the gas discharge/pressure connection and let the vacuum
pump run dry. Therefore the vacuum pump must be shut down at the
latest after 0.5 hours of continuous operation, depending on the oper
-
ating conditions even after a shorter period, for at least approx. 5 min
-
utes (
page 7: Operation Notes). After turning off the vacuum pump
the pressure difference between the inside and the outside of the ex
-
haust filter(s) collapses, hence the two chambers of the oil separator
assume an equal pressure level, the oil return valve between the two
chambers opens and the accumulated oil in the upper chamber can run
down to the bottom chamber.
Cooling
The vacuum pump is cooled by
radiation of heat from the surface of the vacuum pump incl. oil
separator (f)

Safety Notes
The vacuum pump has been designed and manufactured according to
state-of-the-art methods. Nevertheless, residual risks may remain.
These operating instructions highlight potential hazards where appro-
priate. Safety notes are tagged with one of the keywords DANGER,
WARNING and CAUTION as follows:
DANGER_a
Disregard of this safety note will always lead to accidents with fa-
tal or serious injuries.
WARNING_a
Disregard of this safety note may lead to accidents with fatal or se
-
rious injuries.
CAUTION_a
Disregard of this safety note may lead to accidents with minor inju
-
ries or property damage.
Emission of Oil Mist
CAUTION_a
The non-OEM spares market offers exhaust filters that are geomet
-
rically compatible with Busch-vacuum pumps, but do not feature
the high retention capacity of genuine Busch-exhaust filters.
Increased risk of damage to health.
In order to keep the emission on the lowest possible level only gen
-
uine Busch-exhaust filters shall be used.
The oil in the process gas is separated to the greatest possible extent,
but not perfectly.
CAUTION_a
The gas conveyed by the vacuum pump contains remainders of oil.
Aspiration of process gas over extended periods can be harmful.
The room into which the process gas is discharged must be suffi
-
ciently vented.
Note: The possibly sensible smell is not caused by droplets of oil,
though, but either by gaseous process components or by readily vola
-
tile and thus gaseous components of the oil (particularly additives).
Noise Emission
For the sound pressure level in free field according to EN ISO 2151
page 2: Technical Data.
Transport
Note: Also a vacuum pump, that is not topped up with oil contains res
-
idues of oil (from the test run). Always transport and store the vacuum
pump in upright position. Do not put the vacuum pump on its side nor
put it upside down.
Transport in Packaging
Vacuum pumps individually packed in cardboard boxes can be carried
by hand.
Packed on a pallet the vacuum pump is to be transported with a
forklift.
Transport without Packaging
In case the vacuum pump is packed in a cardboard box with inflated
cushions:
Remove the inflated cushions from the box
In case the vacuum pump is in a cardboard box cushioned with rolled
corrugated cardboard:
Remove the corrugated cardboard from the box
In case the vacuum pump is laid in foam:
Remove the foam
Version without handle:
Grasp the vacuum pump with both hands
Version with handle:
Carry the vacuum pump using the handle
CAUTION_a
Tilting a vacuum pump that is already filled with oil can cause large
quantities of oil to ingress into the cylinder.
Starting the vacuum pump with excessive quantities of oil in the cyl
-
inder will immediately break the vanes and ruin the vacuum pump.
Once the vacuum pump is filled with oil it shall not be lifted any
-
more.
Prior to every transport make sure that the oil is drained
Storage
Short-term Storage
Make sure that the suction connection and the gas discharge are
closed (leave the provided plugs in)
Store the vacuum pump
if possible in original packaging,
indoors,
RB/RC 0006 C/E Safety
0870152229 / 110701 page 4
dry,
dust free and
vibration free
Conservation
In case of adverse ambient conditions (e.g. aggressive atmosphere, fre
-
quent temperature changes) conserve the vacuum pump immediately.
In case of favourable ambient conditions conserve the vacuum pump if
a storage of more than 3 months is scheduled.
During the test run in the factory the inside of the vacuum pump was
completely wetted with oil. Under normal conditions a treatment with
conservation oil is therefore not required. In case it is advisable to treat
the vacuum pump with conservation oil because of very adverse stor
-
age conditions, seek advice from your Busch representative!
Make sure that all ports are firmly closed; seal all ports that are not
sealed with PTFE-tape, gaskets or o-rings with adhesive tape
Note: VCI stands for “volatile corrosion inhibitor”. VCI-products (film,
paper, cardboard, foam) evaporate a substance that condenses in mo
-
lecular thickness on the packed good and by its electro-chemical prop
-
erties effectively suppresses corrosion on metallic surfaces. However,
VCI-products may attack the surfaces of plastics and elastomers. Seek
advice from your local packaging dealer! Busch uses CORTEC
VCI 126 R film for the overseas packaging of large equipment.
Wrap the vacuum pump in VCI film
Store the vacuum pump
if possible in original packing,
indoors,
dry,
dust free and
vibration free.
For commissioning after conservation:
Make sure that all remains of adhesive tape are removed from the
ports

Suction Connection
CAUTION_a
Intruding foreign objects or liquids can destroy the vacuum pump.
In case the inlet gas can contain dust or other foreign solid particles:
Make sure that a suitable filter (5 micron or less) is installed
upstream the vacuum pump
Make sure that the suction line fits to the suction connection (c) of
the vacuum pump
Make sure that the gas will be sucked through a vacuum-tight
flexible hose or a pipe
In case of using a pipe:
Make sure that the pipe will cause no stress on the vacuum
pump’s connection, if necessary use an expansion joint
Make sure that the line size of the suction line over the entire
length is at least as large as the suction connection (c) of the
vacuum pump
In case of very long suction lines it is prudent to use larger line sizes in
order to avoid a loss of efficiency. Seek advice from your Busch
representative!
If two or more vacuum pumps work on the same suction line, if the
volume of the vacuum system is large enough to suck back oil or if the
vacuum shall be maintained after switching off the vacuum pump:
Provide a manual or automatic operated valve (= non-return
valve) in the suction line

0870152229 / 110701 page 5
(the standard non-return valve that is installed inside the suction con
-
nection is not meant to be used for this purpose!)
If the vacuum pump is planned to be used for the suction of gas that
contains limited quantities of condensable vapour:
Provide a shut-off valve, a drip-leg and a drain cock in the suc
-
tion line, so that condensates can be drained from the suction
line
Make sure that the suction line does not contain foreign objects,
e.g. welding scales
Gas Discharge
The discharged gas must flow without obstruction. It is not permitted
to shut off or throttle the discharge line or to use it as a pressurised
air source.
The following guidelines for the discharge line do not apply, if the aspi
-
rated air is discharged to the environment right at the vacuum pump.
CAUTION_a
The discharged gas contains small quantities of vacuum oil.
Staying in vacuum oil contaminated air bears a risk of damage to
health.
If air is discharged into rooms where persons stay, sufficient ventila
-
tion must be provided for.
Make sure that the discharge line fits to the gas discharge (d) of
the vacuum pump
In case of using a pipe:
Make sure that the pipe will cause no stress on the vacuum
pump’s connection, if necessary use an expansion joint
Make sure that the line size of the discharge line over the entire
length is at least as large as the gas discharge (d) of the vacuum
pump
In case the length of the discharge line exceeds 1 m it is prudent to use
larger line sizes in order to avoid a loss of efficiency and an overload of
the vacuum pump. Seek advice from your Busch representative!
Make sure that the discharge line either slopes away from the
vacuum pump or provide a liquid separator or a drip leg with a
drain cock, so that no liquids can back up into the vacuum pump
WARNING_ad
Discharge lines made from non-conductive material can build up
static charge.
Static discharge can cause explosion of potentially existing oil
mist.
The discharge line must be made of conductive material or provi
-
sions must be made against static discharge.

Operation Notes
Use
CAUTION_a
The vacuum pump is designed for operation under the conditions
described below.
In case of disregard risk of damage or destruction of the vacuum
pump and adjoining plant components!
Risk of injury!
The vacuum pump must only be operated under the conditions de-
scribed below.
The vacuum pump is intended for
the suction
of
air and other dry, non-aggressive, non-toxic and non-explosive
gases
Conveying media with a lower or higher density than air leads to an in
-
creased thermal and/or mechanical load on the vacuum pump and is
permissible only after prior consultation with Busch.
In case the vacuum pump is equipped with a gas ballast (optional) wa
-
ter vapour within the gas flow can be tolerated within certain limits
(
page 8: Conveying Condensable Vapours). The conveyance of
other vapours shall be agreed upon with Busch.
The vacuum pump is intended for the placement in a non-potentially
explosive environment.
Version with oil return line to the suction connection (RC 0006 C/E):
The vacuum pump is thermally suitable for continuous operation
(100 percent duty).
Version with oil return valve (RB 0006 C/E):
The vacuum pump is thermally suitable for continuous operation (ob
-
serve the notes with regard to the oil recirculation:

-
culation;
page 8: Oil Return).
The vacuum pump is ultimate pressure proof.
RB/RC 0006 C/E Installation and Commissioning
0870152229 / 110701 page 7
CAUTION_ac
During operation the surface of the vacuum pump may reach tem
-
peratures of more than 70 °C.
Risk of burns!
The vacuum pump shall be protected against contact during opera
-
tion, it shall cool down prior to a required contact or heat protection
gloves shall be worn.
CAUTION_a
The gas conveyed by the vacuum pump contains remainders of oil.
Aspiration of process gas over extended periods can be harmful.
The room into which the process gas is discharged must be suffi
-
ciently vented.
Make sure that all provided covers, guards, hoods etc. remain
mounted
Make sure that protective devices will not be disabled
Make sure that cooling air inlets and outlets will not be covered or
obstructed and that the cooling air flow will not be affected ad
-
versely in any other way
Make sure that the installation prerequisites ( page 5: Installation
Prerequisites) are complied with and will remain complied with,
particularly that a sufficient cooling will be ensured
Oil Return
Only for version with oil return valve (RB 0006 C/E):
During operation oil accumulates at the bottom of the upper chamber
of the oil separator (f), which cannot flow down into the bottom
chamber, as long as the vacuum pump runs (for detailed description:
page 3: Oil Circulation).
At the latest after 0.5 hours of continuous operation, in case of high
pressure difference between suction side and pressure side after a
shorter period, the vacuum pump must be shut down for at least
5 minutes, so that the oil can run down from the upper chamber of the
oil separator (f) into the bottom chamber. Note: This is a good time to
check the temperature, the level and the colour of the oil.
Conveying Condensable Vapours
CAUTION_a
Residual condensates dilute the oil, deteriorate its lubricating prop
-
erties and can cause a seizure of the rotor.
Apply a suitable operating method to make sure that no conden
-
sates remain in the vacuum pump.
In order to use the vacuum pump for the conveyance of
condensable vapours, the vacuum pump must be equipped with a
shut-off valve in the suction line and with a gas ballast.
Close the shut-off valve in the suction line
Operate the vacuum pump with the suction line shut off for
approx. half an hour, so that the operating temperature rises to
approx. 75 °C
At process start:
Open the shut-off valve in the suction line
At the process end:
Close the shut-off valve in the suction line
Operate the vacuum pump for another approx. half an hour
Maintenance
DANGER_age32
In case the vacuum pump conveyed gas that was contaminated
with foreign materials which are dangerous to health, harmful ma
-
terial can reside in filters.
Danger to health during inspection, cleaning or replacement of fil
-
ters.
Danger to the environment.
Personal protective equipment must be worn during the handling
of contaminated filters.
Contaminated filters are special waste and must be disposed of
separately in compliance with applicable regulations.
CAUTION_ac
During operation the surface of the vacuum pump may reach tem
-
peratures of more than 70 °C.
Risk of burns!
Prior to action that requires touching of the vacuum pump, let the
vacuum pump cool down, however, if the oil is to be drained, for
no more than 20 minutes (the oil shall still be warm when being
drained)
Prior to disconnecting connections make sure that the connected
pipes/lines are vented to atmospheric pressure
Maintenance Schedule
Note: The maintenance intervals depend very much on the individual
operating conditions. The intervals given below shall be considered as
starting values which should be shortened or extended as appropriate.
Particularly heavy duty operation, such like high dust loads in the envi-
ronment or in the process gas, other contaminations or ingress of pro-
cess material, can make it necessary to shorten the maintenance
intervals significantly.
Daily:
Check the level and the colour of the oil ( page 9: Checking the
Oil)
Weekly:
Check the vacuum pump for oil leaks - in case of leaks have the
vacuum pump repaired (Busch service)
Monthly:
Check the function of the exhaust filter ( page 10: Exhaust Filter)
Make sure that the vacuum pump is shut down and locked against
inadvertent start up
In case an inlet air filter is installed:
Check the inlet air filter, if necessary replace

Checking the Level
Make sure that the vacuum pump is shut down and the oil has col
-
lected at the bottom of the oil separator (f)
Read the level on the sight glass (g)
In case the level has dropped underneath the MIN-marking:
Top up oil ( page 9: Topping up Oil)
In case the level exceeds the MAX-marking:
Excessive dilution with condensates - change the oil and check
the process
If appropriate retrofit a gas ballast (Busch Service) and observe
the chapter Conveying Condensable Vapours (
page 8)
In case the level exceeds the MAX-marking despite proper use of the
gas ballast:
Replace the filter
Topping up Oil
Note: Under normal conditions there should be no need to top up oil
during the recommended oil change intervals. A significant level drop
indicates a malfunction (
page 12: Troubleshooting).
Note: During operation the exhaust filter gets saturated with oil. It is
therefore normal that the oil level will drop slightly after replacement
of the exhaust filter.
CAUTION_a
Filling oil through the suction connection (c) will result in breakage
of the vanes and destruction of the vacuum pump.
Oil may be filled through the filling port (b) only.
CAUTION_a
During operation the oil separator is filled with hot, pressurised oil
mist.
Risk of injury from hot oil mist with open filling port.
Risk of injury if a loosely inserted filling plug (b) is ejected.
Remove the filling plug (b) only if the vacuum pump is stopped.
The vacuum pump must only be operated with the filling plug (b)
firmly inserted.
Make sure that the vacuum pump is shut down and locked against
inadvertent start up
Remove the filling plug (b)
Top up oil until the level reaches the middle of the sight glass (g)
Make sure that the seal ring is inserted into the filling plug (b) and
undamaged, if necessary replace the filling plug (b)
Firmly reinsert the filling plug (b) together with the seal ring
Checking the Colour of the Oil
Note: The oil should be light, either transparent, a little foamy or a little
tarnished. A milky discolouration that does not vanish after sedation of
the oil indicates contamination with foreign material. Oil that is either
contaminated with foreign material or burnt must be changed
(
page 9: Oil Change).
In case the oil appears to be contaminated with water or other conden
-
sates despite proper use of the gas ballast:
Replace the filter
Oil Life
The oil life depends very much on the operating conditions. A clean
and dry air stream and operating temperatures below 100 °C are ideal.
Under these conditions the oil shall be changed every 500 to 2000 op
-
erating hours or after half a year.
Under very unfavourable operating conditions the oil life can be less
than 500 operating hours. Extremely short life times indicate malfunc
-
tions (
page 12: Troubleshooting) or unsuitable operating conditions,
though.
Chosing a synthetic oil instead of a mineral oil can extend the oil life.
To select the oil best suited oil for your process please contact your
Busch representative.
If there is no experience available with regard to the oil life under the
prevailing operation conditions, it is recommended to have an oil anal
-
ysis carried out every 500 operating hours and establish the change in
-
terval accordingly.
