0 Important Safety Information
0.1 Mechanical hazards
1 Avoid exposing any part of the human body to the vacuum.
2 Never operate the pump without a connected intake line or without fit-
ting a blank flange.
3 Do not operate the pump with any of the covers removed.
Serious injury may result.
4 The location at which the TRIVAC BCS (including its accessories) is
being operated should be such that angles over 10° from the vertical
are avoided.
5 The pump when filled with oil must only be moved in its vertical positi-
on. Spilled oil involves the risk of falling.
6 Make sure that the gas flow from the exhaust port is not blocked or
restricted in any way.
7 If exhaust gases must be collected or contained, do not allow the
exhaust line to become pressurised.The pressure in the oil box must
not exceed 0.5 bar (g). An exhaust line which is too small in diameter
or which is blocked can result in the formation of overpressures within
the pump. Possible consequences can be a damaged or even burst
open pump. Thus the exhaust line must be checked from time to time
to ensure that there are no obstructions.
8 When moving the TRIVAC BCS always use the allowed means.
0.2 Electrical hazards
1 The electrical connections must only be provided by a trained electri-
cian as specified, for example, by the regulations EN 50110-1.
Observe local regulations.
2 Lethal voltages are present at the mains connections. Before starting
with any maintenance and service work, de-energise (lockout/tagout)
the product first.
3 Lay connecting lines so that they cannot be damaged. Protect the
lines against humidity and contact with water. Avoid any heat stress on
the line due to unfavourable laying conditions.
4 Suitably support the connecting lines so that the pumps are not
exposed to any major mechanical stress.
5 After a mains power failure the pump will run up automatically again.
This also applies in the case of an emergency shutdown. In order to
prevent the pump from running up automatically again, the pump must
be integrated within a control arrangement such that it can only be
switched on manually again after the mains power has returned.
6 Provide an adequate ground connection for the pump so as to avoid
any electrostatic charging.

0.3 Thermal hazards
1 Under certain ambient conditions the TRIVAC BCS may attain a
temperature of over 70 °C (158 °F). There then exists the danger of
receiving burns.
Note the symbols on the pump pointing to the hazards, and in the
case of a hot pump wear the required protective clothing. All work on
the “pump still warm from operation” should only be done using pro-
tection gloves.
2 Before servicing and maintenance work always leave the pump to cool
down.
Note the warning information on the housing surface. If these warning
notices have been removed, covered or obstructed, include corre-
sponding additional warning notices.
0.4 Hazards caused by materials and substances
1 The vacuum line and the exhaust line must be leaktight. Hazardous
process gases may escape or the pumped gases can react with air or
atmospheric humidity. After installation of the pump and after servicing
work on the vacuum system, a leak search will always be necessary.
When pumping hazardous gases we recommend a leak search on a
regular basis. Leaks in the pump cannot be ruled out under all circum-
stances. When pumping hazardous gases, the operator must ensure
that 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
vacuum 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 pumping oxygen (or other highly reactive gases) at concen-
trations exceeding the concentration in the atmosphere (> 21 % for
oxygen) 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.
4 Before commissioning the TRIVAC BCS, make sure that the media
which are to be pumped are compatible with each other so as to
avoid hazardous situations. All relevant safety standards and regulati-
ons must be observed.
5 When pumping toxic, chemical, radioactive and corrosive gases as
well as pyrophorous substances, the operating company is under the
obligation to comply with the national and international safety
regulations and guidelines. Regarding the suitability of the TRIVAC BCS
pumps for special applications in which such gases, respectively sub-
stances shall be pumped, Leybold should be consulted first.
6 If the pump has previously handled hazardous gases, implement the
proper precautionary measures before opening the intake or exhaust
connection.
CAUTION

Safety information
7GA01301_002_C1 - 07/2018 - © Leybold
Before opening the pump, purge it for a longer period of time with an
inert gas.
If necessary, use gloves, a respirator and/or protective clothing and
work under an exhaust hood. Firmly seal off the pump.
When shipping the contaminated pump for servicing, please also state
the type of hazard. For this you must use a form which we have pre-
pared for you
7 For the TRIVAC BCS-PFPE:
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 in the work area.
Touch the inner sections of the pumps only while wearing clean gloves,
and use clean tools;
work in clean and dry rooms;
after having removed the pump from its packaging, start it up immedi-
ately;
as cleaning agents solvents based on hydrofluorether compounds may
be used.
8 Contaminated parts can be detrimental to health and environment.
Before beginning with any work, first find out whether any parts are
contaminated. Adhere to the relevant regulations and take the neces-
sary precautions when handling contaminated parts.
0.5 Danger of ignition
1 The standard version of the TRIVAC BCS is not suited for operation in
explosion hazard areas.
2 The TRIVAC pumps including the accessories are fundamentally not
suited for pumping of combustible and explosive gases or vapours.
Mixtures of substances may, regarding the fire and explosion risk be
critical or uncritical. The operating company is under the commitment
to analyse this and rate the hazard potential accordingly so as to the-
refrom derive the necessary safety measures which must be intro-
duced.
Provided ignitable or pyrophorous substances are present in the
equipment you must:
■ensure that no air can enter into the equipment,
■ensure that the system is leak-tight,
■with an inert gas purge (with nitrogen, for example) dilute all ignitable
gases or vapours which may enter into the pump through the pump’s
inlet and/or with an inert gas purge reduce the concentration of ignita-
ble gases or vapours in the pump and in the exhaust line to less than
a quarter of the lower explosion limit (LEL) published for the respective
gases.
0.6 Hazard caused by noise
1 The noise level produced by the pump less than 60 dB(A). Suitable
hearing protection measures must be introduced.

0.7 Risk of damaging the pump
1 Before starting up for the first time, the motor circuit must be equipped
with a suitable protective motor switch. Please take note of the infor-
mation in these Operating Instructions and on the electric motor (wiring
diagram).
2 Do not allow the ingestion of small objects (screws, nuts, washers,
pieces of wire, etc.) through the inlet port. For this reason always use
the inlet screen which is supplied as standard.
3 Do not use the pump for applications that produce abrasive or
adhesive powders or condensable vapours that can leave adhesive or
high viscosity deposits. When planning to pump vapours other than
water vapour please contact our sales or service department for
advice.
4 This pump is suited for pumping water vapour within the specified
water vapour tolerance limits.
5 Avoid vapours that can condense into liquids when being compressed
inside the pump, if these substances exceed the vapour tolerance of
the pump.
6 Before pumping vapours the TRIVAC BCS should have attained its
operating temperature. This will be the case approximately 30 minutes
after having started the pump. During this warming up phase, the
pump should be separated from the process, by a blocking valve in
the intake line, for example.
7 In the case of wet processes we recommend the installation of liquid
separators upstream and downstream of the pump as well as the use
of the gas ballast.
8 The exhaust line should be laid so that it slopes down and away from
the pump so as to prevent condensate from backstreaming into the
pump.
9 The entry of particles and fluids must be avoided under all
circumstances.
10 Reactive or aggressive substances in the pump chamber may impair
the operating oil or modify it. In addition, such substances may be
incompatible with the materials of the pump (Viton, grey cast iron, alu-
minium, steel, resins, glass etc.).
11 Corrosion, deposits and cracking of oil within the pump are not
allowed.
12 Normal amounts of humidity within the range of the pump’s water
vapour tolerance will not significantly affect pump performance when
the gas ballast is active.
13 When operating the pumps at gas throughput, it is urgently recom-
mended to connect an exhaust filter or use a suitable exhaust line.
Here, the exhaust line must slope down and away from the pump.
14 In the case of custom pumps please note the information provided in
the supplementary sheets.

1 Description
TRIVAC BCS pumps are oil-sealed rotary vane pumps. The TRIVAC D 40
BCS and D 65 BCS are dual-stage pumps. The number in the type
designation (40 or 65) indicates the pumping speed in m3 · h-1.
The TRIVAC BCS-PFPE have been prepared especially for operation with
perfluoropolyther.
TRIVAC BCS pumps can pump gases and vapours, and evacuate vessels
or vacuum systems in the fine vacuum range.
They have been designed particularly for use in connection with corrosive
or aggressive media. Moreover, the pump has been prepared for the instal-
lation of an electric monitoring facility. Leybold have developed for the
TRIVAC BCS a range of accessories which considerably extend the range
of applications for this kind of pump. These accessories which in connec-
tion with the TRIVAC BCS vacuum pump make up the TRIVAC system, are
described briefly in Chapter 1.5.
Via an intermediate flange the drive motor of the TRIVAC is mounted to the
coupling housing. The pump and motor shafts are directly connected by a
flexible coupling. The bearing points of the pump module are force lubrica-
ted sliding bearings.
All controls as well as the oil-level glass and the nameplate are arranged on
the front. All connections are to be found at the sides of the pump. The oil-
level glass is provided with prisms for better observation of the oil level.
The pump module consists of assembly parts which are pin-fitted so as to
allow easy disassembly and reassembly. The pump module can be easily
removed without special tools.

1.1 Function
The rotor (2/7), mounted eccentrically in the pump housing (2/6), has two
radially sliding vanes (2/5) which divide the pump chamber into several com-
partments. The volume of each compartment changes periodically with the
rotation of the rotor.
As a result, gas is sucked in at the intake port (2/1). The gas passes through
the dirt trap sieve (2/2), flows past the open anti-suckback valve (2/3) and
then enters the pump chamber. In the pump chamber, the gas is passed on
and compressed, after the inlet aperture is closed by the vane.
The oil injected into the pump chamber is used for sealing and lubricating.
The slap noise of the oil in the pump which usually occurs when attaining the
ultimate pressure is prevented by admitting a very small amount of air into the
pump chamber.
The compressed gas in the pump chamber is ejected through the exhaust
valve (2/10). The oil entrained in the gas is coarsely trapped in the internal
demister (2/11); there the oil is also freed of mechanical impurities. The
TRIVAC BCS-PFPE pumps do not have an internal demister. The gas leaves
the TRIVAC BCS-PFPE through the exhaust port.
During compression, a controlled amount of air – the so-called gas ballast –
can be allowed to enter the pump chamber by opening the gas ballast valve.
The gas ballast stops condensation of vapours in the pump chamber up to
the limit of the water vapour tolerance as specified in the technical data for
the pump.

The gas ballast valve is opened (position I) and closed (position 0) by turning
the gas ballast knob (7/5) on the front.
The gas ballast facility of the TRIVAC BCS pump has been prepared for con-
necting the inert gas system IGS.
To enable the TRIVAC BCS to be used at intake pressures as high as 1,000
mbar, a special lubricating system was developed featuring force-lubrication
of the sliding bearings.
An oil pump (3/6) pumps the oil from the oil reservoir (3/5) into a pressure-
lubrication system which supplies oil to all bearing points (3/2). From there
the oil enters the pump chamber area (3/4) of the vacuum pump.
The oil pump is fitted in the front end plate on the coupling side of the pump
module. The oil suction line is placed low, resulting in a large usable oil reser-
voir.
The oil is separated from the gas in the TRIVAC BCS in two steps as descri-
bed above. First, small droplets are coalesced into large drops in the internal
demister (2/11) fitted above the exhaust valve (2/10). Then, the large drops
fall into the oil reservoir as the exhaust gas is diverted by the inner walls of
the oil case. Thus a low loss of oil is obtained. This and the large usable oil
reservoir ensure long intervals between oil changes even at high intake pres-
sures.
The vacuum is maintained by the TRIVAC BCS through an integrated hydro-
pneumatic anti-suckback valve (2/3) which is controlled via the oil pressure.
During operation of the TRIVAC BCS the control piston (4/3) remains sealed
against a spring (4/2) by the oil pressure. The valve disk (4/6) of the anti-
suckback valve is held at the lower position by its own weight (valve open).
When the pump stops (because it has been switched off or because of a fai-
lure), the oil pressure drops and the spring (4/2) presses the control piston
(4/3) up. Thus a connection is provided between the oil case or the oil reser-
voir (4/1) and the piston (4/4) of the anti-suckback valve.
Due to the pressure difference between the oil case and the intake port the
oil presses the piston (4/4) up and the valve plate (4/6) against the valve seat
(4/5). The quantity of oil in the oil reservoir (4/1) prevents the entry of air into
the intake port (2/1) at the beginning of this process.
After the oil has flowed out from the reservoir and when the valve plate rests
on the valve seat, air follows in, which vents the pump chamber and forces
the valve disc (4/6) against its seat. This effectively prevents backstreaming of
oil or oil vapours. The anti-suckback valve (2/3) operates independently of the
operating mode of the pump, i.e. also with gas ballast.
All aluminium surfaces of the TRIVAC BCS are surface protected and thus
particularly capable of resisting aggressive chemicals. A thermocouple has
been incorporated in the pump which is used in connection with the optional
electrical monitoring facility. The thermocouple may be accessed through the
built-in connector (7/8).
Via a second oil fill opening, an exhaust line may be connected for venting
the oil case when using the inert gas purging facility.

1.2 Lubricants
The standard TRIVAC BCS pumps are either ready for operation with mineral oil
or with the special lubricant, perfluoropolyther (PFPE).
If mineral oil and PFPE come into contact they will emulsify. 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 Leybold should do the change.
In case of operation of a TRIVAC BCS we instruct our vacuum pump oil
LVO 100.
In case of operation of a TRIVAC BCS-PFPE we instruct our vacuum pump oil
LVO 400.

When handling PFPE you should observe the following:
During thermal decomposition at temperatures over 290 °C toxic and cor-
rosive gases are released. When handling PFPE keep it way from open
fires. Do not smoke in the work area.
Please note the Material Safety Data Sheet (MSDS) for LVO 400.
Touch the inner sections of the pumps only while wearing clean gloves,
and use clean tools;
Work in clean and dry rooms;
After having removed the pump from its packaging, start it up immediately.
Do not smoke during working with PFPE.
As cleaning agents solvents based on hydrofluorether compounds may be
used.

TRIVAC D65B 3He for Helium Applications
Owing to the particularly stringent leak tightness requirements in connection
with helium applications the TRIVAC D65B 3He (P/N 1129646) is delivered
without gas ballast facilities so as to prevent the admission of gas into the
pump in the event of misoperation. The gas ballast facility has been blanked
off with a closure screw.
The pump has been so designed that it may be evacuated down to a pres-
sure of 50 mbar on its exhaust side for the purpose of avoiding any loss of
expensive gases in the helium circuits. The TRIVAC D65B 3He uses special
gaskets and has been tested to a leak rate specification of <10-7 mbar·l/s.

1)The motor may accelerate with a delay when simultaneously an undervoltage is present at the motor
and the pump is at the minimum permissible and ambient temperature. Under such operating con-
ditions the motor protection switch may respond. In this case the motor may be started again. In the
case of motor 6506961 and 110004011 the minimum permissible temperature is 15 °C at an under-
voltage of 380 V -10% = 342 V and a mains frequency of 60 Hz.
2)Key to the certificate:
UL certification mark for energy efficiency for listed products and approved components for Canada
and the USA.
Observe the data given on the motor name plate.

1.5.1 TRIVAC - System
Leybold has developed the TRIVAC system especially for processes which
depend on the reliability of the pump under difficult conditions (pumping of
aggressive gases or vapours, for example).
Moreover, the pump status may be monitored continuously through visual
and electric indicators.

The TRIVAC system consists of the TRIVAC BCS pump and the following
accessories:
CFS 40-65 chemical filter with safety separating valve
Part No.: 101 77
The CFS is a main flow lubricant filter incorporating a safety separating valve
which may be exchanged while the pump continues to operate. The status of
the interchangeable filters is indicated.
ARS 40-65 exhaust filter with lubricant return
Part No.: 189 57
The ARS filter collects the droplets of lubricant entrained in the exhaust gas
and returns the collected lubricant back into the pump by means of a float
controlled valve. This reduces the consumption of lubricant by the pump to
an insignificant level so that a daily oil check will no longer be necessary. The
status of the filter element may be checked at any time through the differenti-
al pressure indicator.
IGS 40-65 inert-gas-system
Part No.: 161 68V
This accessory which may be controlled through a solenoid valve allows the
definite injection of controlled quantities of gas into the TRIVAC BCS.
Thus it offers the possibility of effectively reducing contaminants in the lubri-
cant of the system and the materials of the system itself.
LSS 40-65 limit switch system
Part No.: 161 07
This accessory consists of a package of limit switches and serves the purpo-
se of monitoring the operation of the system.
Included with the limit switch system are one eac
■oil pressure switch (operating pressure)
■float switch (oil level monitoring)
■low switch (inert gas)
■differential pressure switch (chemical filter)
■pressure switch (exhaust filter)
■connection cable for the built-in temperature switch
EIS 40-65 electrical indicator system
Part No.: 160 97
This accessory combines all switch status signals and indicates the status of
these switches through LEDs: “GREEN” for normal operation, “RED” for fault.
Through a multi-way connector all signals may be accessed for transmission
to a remote processing unit.
