0 Important Safety Information
0.1 Mechanical Hazards
1 In order to avoid the destruction of systems and injury to operating
personnel we urgently recommend to observe the information and
installation information provided in these Operating Instructions.
2 Avoid exposing any part of the human body to the vacuum.
3 Do not operate the pump with an opened intake port. There exists the
risk of suffering injury.
Even during standstill of the RUVAC it is dangerous to grasp into the
pump casing. Fingers can easily be squeezed between impellers due
to the high inertia of the parts. Please use caution when grasping into
the pump and make sure that the pump is secured against unwanted
rotation due to differential pressures.
4 The pump is intended for generating a vacuum only. If an overpressure
can occur in the pump and the system then they must be protected
against such an overpressure by an overpressure safety valve, for
example.
5 When using purge gas, protect the purge gas supply so that in the
event of a malfunction or power interruption no overpressure can
occur within the pump system.
6 For transporting the pump use only suitable transport means.
When selecting the lifting and transport means take note of the total
weight before transporting the pump.
As standard, the pump has been equipped with four crane eyes.
When transporting the pump with a forklift or similar, ensure that the
pump has been secured on the forks or on a suitable pallet.
The lifting eye of the screw pump must never be used to lift any pump
combinations (Roots pump + backing pump).
7 Select the location where the pump is installed so that all controls can
be easily accessed. Place the pump only on a floor which is level. It
can topple when it is tilted by more than 10° with respect to the verti-
cal axis.
WARNING
Safety information
6 130001398_002_C0 - 09/2016 - © Leybold
8 Before beginning with any maintenance and servicing work always
ensure that no gas can flow backwards through the pump since then
the rotors might turn against the normal direction of rotation. For this
reason vent the vacuum chamber to the discharge pressure level or
ensure through suitable valves that the vacuum chamber and the lines
are reliably separated from the pump. When connecting several pump
systems, pressure differences between intake and discharge can give
rise to uncontrolled turning of the pump’s shafts.
9 During operation, the cooling water circuit must not be shut off. A
cooling water discharge which has been blocked can cause the for-
mation of gas bubbles and result in excessively high pressures.
10 Lay electric feed and cooling water lines so that there is no risk of trip-
ping over these.
11 When changing the oil remove any escaped oil as otherwise there is
the risk of slipping.
12 Before doing installation work on the pump system make sure that no
vacuum is present in the pump and that all media connections have
been depressurised.
13 Before disassembling any cooling water lines, leave the pump to cool
down, shut off the feed line.
14 The pumps must only be operated at the permitted speeds. Especially
when using frequency converters which have not been specifically
approved by Leybold, you need to ensure an effective protection
against overspeeding.
15 Should malfunctions affect the pump, seized impellers in particular
owing to hard deposits or foreign objects, the occurrence of leaks
affecting the housing cannot be ruled out. When pumping hazardous
gases the operator must ensure that the possibility of such an incident
is excluded, respectively that leaks at the pump casing will not pose a
hazard.

0.2 Electrical Hazards
1 The electrical connection must only be provided by a trained person.
Please observe the national regulations in the country of use like
EN50110-1 for Europe, for example.
2 Potentially lethal voltages are present at the mains connections. Before
beginning with any maintenance or service work on the pump, discon-
nect the pump from all power supplies (lockout/tagout). In addition,
there is the danger of residual voltage for up to 5 minutes after discon-
nection.
3 Install a device for a safe disconnection from the power supply.
4 High electric voltages! When touching parts at high electric voltages,
there is the risk of suffering severe injuries by an electric shock! Covers
marked with this symbol must only be opened by trained electricians
after having reliably deenergised (lockout/tagout) the equipment.
5 Note the information on the IP type of protection.
6 Always operate the pump with a properly connected protective earth
conductor and make sure that the motor casing is closed.
7 Observe the manufacturer’s information and operating instructions for
the respective frequency converter.
8 The pump must only be operated at the frequency specified for the
motor. For the WH 2500 use only the Leybold frequency converter.
9 For pumps with external frequency converter: after having connected
the motor and each time after having made changes to the wiring,
check the motor’s direction of rotation.
A wrong direction of rotation can cause a pressure buildup on the
intake side. Moreover, the pump may suffer severe damage.
10 Install a suitable motor protection for the electric motor before starting
up for the first time. Note the information in these Operating
Instructions and on the nameplate.
11 Before starting, check to ensure that the junction box is undamaged,
run a visual inspection on the seals.
12 Install add-on parts (pressure switches, for example) without any
mechanical tensions and protect these against being damaged by
impacts, for example.
13 Lay the connecting lines so that these cannot be damaged. Protect
the lines against humidity and contact with water. Avoid thermally
stressing the lines by unfavourable laying. Comply with the required
standards when designing and laying the electrical connections.
14 Provide strain relief for the connecting lines so that the plugs and the
line connectors are not subjected to excessively high mechanical
stresses.
15 Lay electric lines so that there is no risk of tripping over these.
DANGER
Safety information
8 130001398_002_C0 - 09/2016 - © Leybold
16 For models with external frequency converter only:
Consider the following precautions for the output circuit wiring.
Do not connect any other load than a 3 phase motor to the frequency
converters output.
Never connect a power source to the frequency converters output.
Never short or ground the output terminals.
Do not use phase correction capacitors.
17 The pump must be integrated in the system control arrangement so
that it can not run-up automatically after it has been shut down due to
overtemperature. This applies equally to emergency shut-down
arrangements. After having determined the fault cause, the pump
should be switched on manually again.
18 Work on the frequency converter within the motor casing must always
be left to suitably instructed personnel only.
0.3 Thermal Hazards
1 Hot surfaces, risk of suffering burns
Under certain ambient conditions the pump may attain temperatures
over 80° C. There then exists the risk of suffering burns. Note the dan-
ger symbols on the pump and in the case of a hot pump wear the
required protection equipment.
If there is the risk of touching hot surfaces inadvertently, install corre-
sponding protection. When working on a pump which is still warm
from operation, always wear protective gloves.
2 Handle the pump only while vented and after having let it cool down.
3 Before disassembling any cooling water lines, leave the pump to cool
down first, then shut off the feed line.
4 When uninstalling the cooling water lines, take note of splashing water.
Heated water can cause burns.
5 Never remove the oil-fill or oil-drain plugs while the pump is running.
There exists the risk of suffering burns. Always wear protective gloves
and protective goggles also for protection against the oil.
6 Operating the pump with less than the specified amount of cooling
water will result in excessively high surface temperatures which can
damage the pump. Moreover, there exists the risk of suffering burns.
CAUTION

0.4 Hazards Caused by Materials and Substances
1 The vacuum line must be leaktight. Hazardous process gases may
escape or the pumped gases can react with air or atmospheric humid-
ity. After installation of the pump and after servicing work on the vacu-
um system, a leak test will always be necessary.
When pumping hazardous gases we recommend a leak test on a reg-
ular basis. Leaks in the pump cannot be ruled out under all circum-
stances. When pumping hazardous gases, the operator must ensure
that leaks at the pump will not be a hazard.
2 Since not all application related hazards for vacuum systems can be
described in detail in these Operating Instructions, Leybold has availa-
ble a separate document (Safety Booklet) in which the hazards and
general safety concepts for design, operation and maintenance of vac-
uum systems are explained.
When planning to pump hazardous substances with this pump, read
the related chapters in the Safety Booklet and in these Operating
Instructions first. You can download the Safety Booklet from our
homepage.
3 Before commissioning the pump, make sure that the media which are
to be pumped are compatible with each other so as to avoid hazard-
ous situations.
4 If required additional monitoring of the purge gas quantities is neces-
sary from the side of the operator when a well-defined and ensured
dilution is necessary from the side of the process.
The type of protection depends on the specific process and needs to
be assessed by of the customer.
5 The cooling water from the return is not of drinking water quality and
should not be used for this purpose.
After having operated the pump, the cooling water lines may suffer
from microbiological contamination. Take appropriate safety precau-
tions.
6 When the pump has been used to pump hazardous gases before,
introduce appropriate safety precautions before opening the intake or
the discharge connections. Before opening the pump, purge it for a
longer period of time with an inert gas. If necessary, wear suitable per-
sonal protection equipment like gloves, breathing protection and pro-
tection clothing, for example (see Material Safety Data Sheets for the
substances in use, the chemical reactions and the by-products). Firmly
seal off the pump. When shipping the contaminated pump for servic-
ing please also indicate the type of hazard. For this see Section 5.5
Service at Leybold.
7 Leybold is not in a position to perform servicing (repairs) and waste
disposal of radioactively contaminated pumps. Both needs to be
ensured from the side of the user.
DANGER
Safety information

8 When disposing of the pump, used lubricants and used oil filters,
observe the applicable environment regulations.
9 When pumping hazardous gases you must assume the presence of
hazardous residues in the pump.
10 If the pump has been contaminated by the process or through envi-
ronmental influences, it must be decontaminated professionally.
Contaminated parts can be detrimental to health and the environment.
Before beginning with any repair and maintenance work inform yourself
about any possible contamination. When handling contaminated parts
observe the pertinent regulations and comply with the necessary pro-
tection measures.
When shipping contaminated pumps which require approval by the
authorities, note the applicable regulations regarding packaging and
shipping.
11 Some pumps use perfluoropolyether (PFPE) as lubricant.
When handling PFPE you should observe the following:
During thermal decomposition at temperatures over 290 °C toxic and
corrosive gases are released. When handling PFPE keep it way from
open fires. Do not smoke with PFPE on your fingers.
Touch the inner sections of the pumps only while wearing clean gloves,
and use clean tools;
do the necessary work in clean and dry rooms;
after having removed the pump from its packaging, start it up as
quickly as possible;
as cleaning agents, solvents, based on hydrofluorether compounds
may be used.
12 Fluoropolymers are used as sealants (FKM) and as lubricants (PFPE) in
the pumps. In case the pump suffers a severe mechanical failure, the
possibility of hazardous substances being released owing to their ther-
mal decomposition cannot be excluded. The hazards caused by such
decomposition are described in the Material Safety Data Sheets for the
materials, for example.

0.5 Ignition Risk
1 The standard version of the pump is not suited for operation in explo-
sion hazard areas. Contact us before planning to use the pump under
such circumstances.
2 Before pumping oxygen (or other highly reactive gases) at concentra-
tions exceeding the concentration in the atmosphere (> 21 % for oxy-
gen) it will be necessary to use a special pump. Such a pump will have
to be modified and degreased, and an inert special lubricant (like
PFPE) must be used.
0.6 Noise Hazard
1 The noise level produced by the RUVAC is between 63 and 75 dB(A).
When operating the pump temporarily at pressures above 100 mbar
the noise level can be much higher. Make sure that suitable protection
measures are taken to protect your hearing.
2 When the pump is being started with open flanges, a noise level which
is detrimental to health will be produced. If such operation is unavoid-
able, then it is mandatory to wear hearing protectors (ear muffs).
0.7 Dangers in Connection with Safety-related Measures and
Precautions
1 The pump is not equipped with an emergency shutdown facility.
2 The following applies to pumps being operated with a frequency con-
verter: after a mains power failure the pump will automatically start up
again once the power returns.
3 Take note of the warning information on the casing surface. If this
warning information was removed, covered or obstructed, then pro-
vide corresponding additional warning information.

0.8 Danger of Pump Damage
1 Select an installation site for the pump so that all controls are easily
accessible.
2 With the pump filled with oil it must placed such that it will deviate by
no more than 2° from the vertical axis as otherwise oil can enter into
the sealing system.
WH/WHU 4400 and 7000: Before filling the pump with oil, align it.
Transporting the pump filled with oil is not permissible.
WH/WHU 2500: The pumps are supplied filled with oil. For this reason
they should, while being transported or shipped, not be subjected to
much tilting.
3 Do not allow the ingestion of any objects (screws, welding beads,
nuts, washers, pieces of wire, etc.) through the intake port of the
pump.
Use the intake screen which has been fitted as standard to prevent
ingestion of objects during commissioning, after this it must be
removed. This will allow full vacuum performance to be achieved and
will eliminate the risk that a damaged intake screen could enter the
pump inlet.
Objects falling into the pump can cause severe damage to the pump
including leaks to atmosphere; therefore the design of the pipework
and vacuum chamber should prevent this possibility. For more detail
please consult our Safety Booklet.
The intake screen does not replace a filter. Prevent the intake of parti-
cles by fitting suitable filters or traps.
4 When pumping dust containing media, install a dust filter in the pro-
cess gas flow upstream with respect to the pump.
5 When connecting the pump, provide a suitable valve on the intake side
for the purpose of shutting off the intake line so as to prevent the
pump from turning backwards in the event of a power failure.
Otherwise the pump may suffer damage or oil may contaminate the
pump chamber.
6 Lines and other vacuum connections should be clean and free of oil.
Special attention must be paid here when oil-sealed pumps have been
used on the vacuum side. Check the conditions before initial commis-
sioning. In the case of deviations, the pump can suffer contamination
with oil residues.
7 The discharge line should be laid so that it slopes down and away
from the pump so as to prevent condensed vapours from backstream-
ing into the pump.
8 In the case of wet processes we recommend the installation of liquid
separators, upstream and downstream of the pump so as to avoid the
influx of liquid into the pump. During installation work on the intake and
discharge lines do not subject flanges to any stresses. Check the rub-
ber elements of the pump’s feet as to any deformation.
NOTICE
Safety information
13130001398_002_C0 - 09/2016 - © Leybold
9 Before pumping condensable vapours the pump should be at operat-
ing temperature. If a gas ballast is present, then it should be opened.
The pump will attain its operating temperature approximately 30 min-
utes after having started the pump. During this warm-up phase, the
pump should be left separated from the process by a valve in the
intake line, for example.
10 With the pump warm from operation do not clean it from the outside
with water. There is the risk of a rotor crash due to shock cooling.
11 If condensable vapours have been pumped, the pump should before
switching off be purged for about 15 minutes with an inert gas or air
(depending on the specific application). This process should also be
run before cleaning the pump chamber.
12 For shutting down the pump let the pump operate idle for at least 30
minutes. Disconnect the pump from the mains power. Place desiccant
into the intake flange and into the discharge flange and blank off the
flanges with a piece of foil.
When storing the pump for a longer period of time, drain out the oil
first. Package the pump airtight in polyethylene foil.
13 Improper maintenance or repair work can have an influence on the
service life and the performance of the pump and will void any warran-
ty claims.
14 Maximum cooling water pressure: 6 bar. When exceeded, there is the
risk of leaks.
15 The pump must only be operated at ambient temperatures between
10 and 40 or 50 °C. The thermal radiation produced by the pump
must be removed to a sufficient extent. If for whatever reason the
pump needs to be operated at higher ambient temperatures, then
reduced maximum pressure differences apply (derating). For operation
under such conditions please consult Leybold.
16 In order to prevent the transfer of vibrations from the RUVAC to other
system components which have been connected, we recommend fit-
ting of corrugated hoses respectively compensators on the intake and
the discharge side.
17 Do not operate the RUVAC WH/WHU in connection with backing
pumps where an ultimate pressure exceeding 10 mbar is specified.
This will prevent excessively high temperatures when the RUVAC is
running idle.
18 The ingress of particles and liquids must be avoided under all circum-
stances.
Pressures stated in bar or mbar are absolute pressures, except something
else is expressly mentioned (for example, bar(g))

1 Description
1.1 Design and Function
The RUVAC WH and RUVAC WHU are Roots boosters driven by water
cooled hermetically sealed motors.
The WHU types have a pressure balance line between the discharge and
intake flanges.
The RUVAC WH and WHU are lubricated with synthetic oil or perfluorized
polyether (PFPE).
Only specially prepared RUVAC WH/WHU PFPE pumps can be used for
pumping oxygen greater than atmospheric concentration.
Only RUVAC WH/WHU PFPE pumps can be used for pumping very aggres-
sive or hazardous gasses. In these cases it is imperative that you consult
your local Leybold office.
The RUVAC WH/WHU 2500 can pump gas in the vertical direction, the
RUVAC WH/WHU 4400 und 7000 in the vertical or horizontal direction.
Although the pumping chamber of Roots pumps is in principle free of sealing
agents and lubricants, the two gearwheels of the synchromesh gearing and
the bearings are lubricated with synthetic oil or with PFPE. The two bearing
chambers are separated from the pumping chamber by the impeller seals.
The RUVACs are driven by a water cooled hermetically sealed motor. The
hermetically sealed motor runs completely under vacuum and is sealed
against atmosphere. Thus a shaft feedthrough to the atmosphere is not
needed.

With the standard motors, the RUVAC WH/WHU 4400/7000 can run on
either 50 Hz or 60 Hz power supplies or with an appropriate frequency con-
verter. The RUVAC WH/WHU 2500 are available with motors for 50 Hz or 60
Hz power supplies or with internal or external frequency converter.
RUVAC WH/WHU pumps are water cooled by cooling water tubes integrated
into the motor casing and the gearbox cover. A connection tube allows the
cooling water to flow through both housing parts.
Built into the stator coil of the motor is a temperature switch (PTO) and a
PTC that have to be analysed when the motor is not operated in connection
with a frequency converter so as to shut down the pump should the motor
overheat.
In the case of RUVAC WH pumps equipped with a frequency converter from
Leybold, the frequency converter has been set up through pre-defined
parameters for the purpose of protecting the pump. The built-in pump tem-
perature sensor can be connected providing additional protection against
thermally overloading the pump.
Fig. 1.2 Schematic diagram of a Roots pump with pressure balance line
Pressure balance valve
Pressure balance line
(bypass line)
Pressure Balance Line (Bypass Line)
The RUVAC WHU has an integrated pressure balance line. It links the dis-
charge and intake flanges via a pressure balance valve. The valve is spring-
loaded. It works with both vertical and horizontal flow of the pump.
If the differential pressure between the flanges is too large, the valve opens.
Some of the gas which has already been pumped flows back through the line
to the intake flange.
The RUVAC WHU pumps are optimized for fast atmospheric cycling. They
should be used in combination with a suitable roughing pump to achieve
short pumpdown times for example in load lock applications. The RUVAC
WHU pumps can be switched on together with a backing pump at atmos-
pheric pressure. Thus the pumping speed of the pump combination is
increased also at high intake pressures.
Description
16 130001398_002_C0 - 09/2016 - © Leybold
The pressure balance valve will not protect the pump from thermal over-
load if opened continuously.
1.1.4 Lubricants
RUVAC WH/WHU pumps described here are, as standard, prepared either
for operation with synthetic oil or the special lubricant perfluoropolyether
PFPE). Other types of oil (white oil, for example) upon request.
If synthetic oil and PFPE come into contact with each other they will emul-
sify. That’s why the pumps must only be run with the type of lubricant
specified for the pump. If you want to change the type of lubricant please
contact Leybold.
1.2 Standard Specification
RUVAC WH/WHU are supplied for vertical flow.
WH/WHU 4400 and 7000: Before delivery the oil has been drained out. The
quantity of synthetic oil or PFPE which is required for operation, is supplied
separately with the pump..
WH/WHU 2500: The pumps are filled with synthetic oil or PFPE.
All pumps are equipped with an intake screen in their intake flange and have
been vented with nitrogen to protect the pump against corrosion. The flanges
have been sealed off with adhesive foil.
The RUVAC WH 2500 pumps with an internal frequency converter are
supplied together with the frequency converter. RUVAC 2500 pumps intend-
ed for operation with an external frequency converter are supplied without
the frequency converter but with a 30 m long connecting cable for the built-in
Pt 1000 temperature sensor.
