by using a pipe DN10 (
≤
12 mm):
≤
3 m
Additionally, it is allowed to install the following approved reservoirs
between nozzle and gas recovery pump:
−
snubber 250ml of the manufacturer Scheidt&Bachmann, No.
0582543 (documented in confidence test report PTB Ex 05-
45017)
−
Condensate separator of the manufacturer Fafnir, No. XO
013001 (documented in confidence test report PTB Ex 05-
45027)
Observe the following installation conditions for reservoirs:
−
distance of the reservoir to the gas recovery pump: 0,3 m to 2,5
m
−
Min. length of the pipe between hose and reservoir: 0,5 m
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. The shaft of the vacuum pump is driven by the drive motor shaft
by means of a flexible coupling.
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.
By the bypass valve (f) a preset differential pressure on the suction
side will not be exceeded.
The vacuum pump compresses the inlet gas absolutely oil-free. A lu-
brication of the pump chamber is neither necessary nor allowed.
Cooling
The vacuum pump is cooled by
−
radiation of heat from the surface of the vacuum pump
−
the process gas
Start Controls
The vacuum pump comes without start controls. The control of the
vacuum pump is to be provided in the course of installation.
Safety
Intended Use
Definition: For the purpose of these instructions, “handling” the vac-
uum pump means the transport, storage, installation, commissioning,
influence on operating conditions, maintenance, troubleshooting and
overhaul of the vacuum.
The vacuum pump is intended for industrial use. It shall be handled
only by qualified personnel.
The allowed media and operational limits (
➔
page 3: Product De-
scription) and the installation prerequisites ( ➔ page 5: Installation
Prerequisites) of the vacuum pump shall be observed both by the
manufacturer of the machinery into which the vacuum pump is to be
incorporated and by the operator.
In particular the intended use in potentially explosive areas, i.e. either
inside the vacuum pump or in its adjacency potentially explosive at-
mosphere can occur, requires that the vacuum pump is equipped ac-
cordingly and carries the Ex-mark and that the associated documenta-
tion acc. to the directive 2014/34/EU is available.
The maintenance instructions shall be observed.
Prior to handling the vacuum pump these installation and operating
instructions shall be read and understood. If anything remains to be
clarified please contact your Busch representative!
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:
Noise Emission
For the sound pressure level in free field according to EN ISO 2151

Transport
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 fork-
lift.
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 packed 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
•
Grasp the vacuum pump with both hands
•
Check the vacuum pump for transport damage
Note : Do not operate the vacuum pump in case of transport damage!
DANGER
Disregard of this safety note will always lead to accidents with
fatal or serious injuries.
WARNING
Disregard of this safety note may lead to accidents with fatal or
serious injuries.
CAUTION
Disregard of this safety note may lead to accidents with minor in-
juries or property damage.
