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 1.6 B is a single-stage pump, and the TRIVAC
D 1.6 B is a dual-stage pump. The number “1.6” in the
type designation 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 connections are arranged on top of
the pump. The oil-level glass is provided with prisms for
better observation of the oil level.

1.1 Function

The rotor (1/7), mounted eccentrically in the pump
housing (1/6) (pump chamber), has two radially sliding
vanes (1/5) 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 (1/1). The
gas passes through the dirt trap sieve (1/2), flows past
the open anti-suckback valve (1/3) 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 (1/9). The oil entrained in the
gas is trapped by diversion at the inner walls of the oil
case and is then returned to the oil reservoir.

Fig. 1 Sectional drawing of the TRIVAC-B

The gas leaves the TRIVAC-B through the exhaust port.

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. The gas
ballast stops condensation of vapours in the pump up to
the limit of vapour tolerance as specified in the technical
data for the pump.

The gas ballast valve is opened and closed by turning
the gas ballast knob (5/2) on the front.

The lubricating system allows to employ the TRIVAC-B at
intake pressures as high as 1000 mbar.

The built-in anti-suckback valve (1/3) seals the pump’s
intake and vents the pump during shutdown. Sealing the
pump’s intake prevents oil from entering the intake line
during shutdown and holds the vacuum in the system.
The anti-suckback valve functions independently of the
pump’s operating mode, i. e. during gas ballast
operation, too.

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.

2.1 Installation

The standard pump is not suited for
installation in explosion hazard areas.When
planning such an application please contact
us first.

The TRIVAC-B pump can be set up on a flat, horizontal
surface. Rubber feet under

the coupling housing ensure that the pump can not slip.

If you wish firmly install the pump in place, insert bolts
through bore holes in the rubber feet.

Max. tilt for the pump (without further
attachment) with possibly fitted standard
accessories is 10ϒ from the vertical.

The rubber feet act as vibration absorbers.
They must therefore not be compressed by
screws. When installing the TRIVAC-B
pump, make sure that the connections and
controls are readily accessible.

The site chosen should allow adequate air
circulation to cool the TRIVAC-B (keep front
and rear unobstructed). The ambient
temperature should not exceed +40 ϒC and
not drop below +12 ϒC (see Section 2.5.3).
The max. amount of heat given off
approximately corresponds to the rated
motor power.

2.2 Connection to the
System

Before connecting the TRIVAC-B, remove the shipping
seals from the connection flanges (5/2) and (5/3).

Retain the shipping seals in case you need
to store the pump in the future.

Connect the intake and exhaust lines with a centering
ring and a clamping ring each. Use the centering ring
with dirt trap for the intake port.

Connect the intake and exhaust line using anti-vibration
bellows, without placing any strain on the pump.

Upon request the TRIVAC may also be connected via
hose nozzles.

The intake line must be clean. Deposits in the intake line
may outgas and adversely affect the vacuum. The
connecting flanges must be clean and undamaged.

The maximum throughput of the pump is equivalent to
the pumping speed of the pump (see Section 1.6).

The cross-section of the intake and exhaust
lines should be at least the same size as
the connection ports of the pump. If the
intake line is too narrow, it reduces the
pumping speed. If the exhaust line is too
narrow, overpressures may occur in the
pump; this might damage the shaft seals
and cause oil leaks. The maximum pressure
in the oil case must not exceed 1.5 bar
(absolute).

When pumping vapours, it is advisable to
install condensate traps on the intake and
exhaust sides.

Install the exhaust line with a downward
slope (lower than the pump) so as to
prevent condensate from flowing back into
the pump. If this is not possible, insert a
condensate trap.

The exhaust gases from the vacuum pump
must be safely lead away and subjected to
post-treatment as required. In order to
reduce the emission of oil vapours we
recommend the installation of an additional
exhaust filter (Leybold accessory).
