Leybold Service
If a pump is returned to Leybold, indicate whether the
pump is free of substances damaging to health or
whether it is contaminated.
If it is contaminated also indicate the nature of the
hazard. Leybold must return any pumps without a
“Declaration of Contamination” to the sender’s address.
Disposal of waste oil
Under the amended law relating to waste disposal dated
November 1, 1986 (valid in the Federal Republic of
Germany) the disposal of used oil is subject to new
provisions. According to legislation relating to waste
disposal the so-called principle of causality is applied.
Hence, anyone in possession of used oil is responsible
for its proper disposal.
Used oils coming from vacuum pumps must not be
mixed with other substances.
Used oils from vacuum pumps (LH-oils on the basis of
mineral oils) having been affected by normal
contamination due to oxygen from the ambient air,
increases in temperature and mechanical wear, must be
disposed of as used oil in accordance with the
regulations. Used oils from vacuum pumps that have
been contaminated by other substances must be
labelled, stored and disposed of as special waste with
reference to the kind of contamination.
When disposing of used oil please observe the safety
regulations that are valid in your country.
In many countries proof of were the oil has finally been
left is required by Law and often shipping of such
contaminated waste requires permission by the
authorities. Waste disposal information is available
through:

1 Description
TRIVAC-B pumps are oil-sealed rotary vane pumps.The
TRIVAC S 4 B and S 8 B are single-stage pumps, and
the TRIVAC D 4 B and D 8 B are dual-stage pumps.The
number in the type designation (4 or 8) indicates the
pumping speed in m3x h-1.
TRIVAC-B pumps can pump gases and vapours and
evacuate vessels or vacuum systems in the fine vacuum
range. Those of standard design are not suitable for
pumping greater than atmospheric concentrations of
oxygen, hazardous gases, or extremely aggressive or
corrosive media.
The drive motor of the TRIVAC-B is directly flanged to
the pump at the coupling housing. The pump and motor
shafts are directly connected by a flexible coupling.The
bearing points of the pump module are force lubricated
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) (pump chamber), has two radially sliding
vanes (2/5) which divide the pump chamber into several
compartments. 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
gas leaves the TRIVAC-B through the exhaust por t.
During compression, a controlled amount of air – the socalled gas ballast – can be allowed to enter the pump
chamber by opening the gas ballast valve.

Fig. 1 TRIVAC-B with accessories
The gas ballast stops condensation of vapours in the
pump chamber up to the limit of vapour tolerance as
specified in the technical data for the pump (the data
refer to water vapour).
The gas ballast valve is opened and closed by turning
the gas ballast knob (7/5) on the front.
To enable the TRIVAC-B 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-B in two
steps as described 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 pressures.
Description
The vacuum is maintained by the TRIVAC-B through an
integrated hydropneumatic anti-suckback valve (2/3)
which is controlled via the oil pressure.
During operation of the TRIVAC-B the control piston (4/3)
remains sealed against a spring (4/2) by the oil pressure.
The valve disc (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 failure), 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
reservoir (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 v alve disc
(4/6) against its seat. This effectively prevents
backstreaming of oil. The anti-suckback valve (2/3)
operates independently of the operating mode of the
pump, i.e.also with gas ballast.

1.5 Transportation
• Pumps which are filled with operating
agents must only be moved while
standing upright. Otherwise oil may
escape. Avoid any other orientations
during transport.
• Check the pump for the presence of any
oil leaks, since there exists the danger
that someone may slip on spilt oil.
• When lifting the pump you must make
use of the crane eyes provided on the
pump for this purpose; also use the
recommended type of lifting device.
