NOTE
Technical term.
In this instruction manual, we consider that the term ‘machine’ refers to the ‘vacuum
pump’.
2.1 Operating Principle
The machine works on the claw principle.
Transport | 3
0870159870_MV1202A_A0001_IM_en 5 / 20
2.2 Application
The machine is intended for the suction of air and other dry, non-aggressive, non-toxic
and non-explosive gases.
Conveying of other media leads to an increased thermal and/or mechanical load on the
machine and is permissible only after a consultation with Busch.
The machine is intended for the placement in a non-potentially explosive environment.
The machine is suitable for continuous operation.
Permitted environmental conditions see Technical Data [}18].
2.3 Standard Features
2.3.1 Vacuum Relief Valve
The ultimate pressure is limited by a vacuum relief valve. The vacuum relief valve is adjusted ex-works to the minimum permitted ultimate pressure (see nameplate).
2.4 Optional Accessories
2.4.1 Inlet Filter
It protects the machine against dust and other solids in the process gas. The inlet filter is
available with a paper or polyester cartridge.

• Check the machine for transport damage.
In case of the machine being secured to a base plate:
• Remove the fixations.
WARNING
Lifting the machine using the motor eye bolt.
Risk of severe injury!
• Do not lift the machine using the eye bolt fitted to the motor. Only lift the machine as
previously shown.
4 Storage
• Seal all apertures with adhesive tape or reuse provided caps.
In case of storage of more than 3months is scheduled:
• Wrap the machine in a corrosion inhibiting film.
• Store the machine indoors, dry, dust free and if possible in original packaging
preferably at temperatures between 0 ... 40 °C.

• Make sure that the environment of the machine is not potentially explosive.
• Make sure that the ambient conditions comply with the Technical Data [}18].
• Make sure that the environmental conditions comply with the protection class of the
motor.
• Make sure that the installation space or location is vented such that sufficient cooling
of the machine is provided.
• Make sure that cooling air inlets and outlets are not covered or obstructed and that
the cooling air flow is not affected adversely in any other way.
Installation | 5
0870159870_MV1202A_A0001_IM_en 7 / 20
• Make sure that the oil sight glass (OSG) remains easily visible.
• Make sure that enough space remains for maintenance work.
• Make sure that the machine is placed or mounted horizontally, a maximum of 1° in
any direction.
• Check the oil level, see Oil Level Inspection [}11].
• Make sure that all provided covers, guards, hoods, etc. are mounted.
5.2 Connecting Lines / Pipes
• Make sure that the connection lines cause no stress on the machine‘s connection, if
necessary use flexible joints.
• Make sure that the line size of the connection lines over the entire length is at least as
large as the connections of the machine.
In case of very long connection lines it is advisable to use larger line sizes in order to
avoid a loss of efficiency. Seek advice from your Busch representative.
5.2.1 Suction Connection
NOTICE
Intruding foreign objects or liquids.
Risk of damage to the machine!
In case of the inlet gas contains dust or other foreign solid particles:
• Install a suitable filter (5micron or less) upstream the machine.
Connection size:
– DN100 PN10/16
Depending on the specific order, other connection dimensions may apply.
5.2.2 Discharge Connection
Connection size:
– DN100 PN10/16
Depending on the specific order, other connection dimensions may apply.
• Make sure that the discharged gas will flow without obstruction. Do not shut off or
throttle the discharge line or use it as a pressurised air source.
Unless the aspirated air is discharged to the environment right at the machine:
• Make sure that the discharge line either slopes away from the machine or provide a liquid separator or a siphon with a drain cock, so that no liquids can flow back into the
machine.
5.3 Filling Oil
The oil level should stay constant over the lifetime of the oil. If the level does fall, the
gear is leaky and the machine requires repair.

6 Commissioning
NOTICE
Lubricating a dry running machine (process chamber).
Risk of damage to the machine!
• Do not lubricate the process chamber of the machine with oil or grease.
CAUTION
During operation the surface of the machine may reach temperatures of more than
70°C.
Risk of burns!
• Avoid contact with the machine during and directly after operation.
CAUTION
Noise of running machine.
Risk of damage to hearing!
If persons are present in the vicinity of a non noise insulated machine over extended
periods:
• Make sure that ear protection is being used.
• Make sure that the installation conditions (see Installation Conditions [}6]) are complied with.
• Switch on the machine.
• Make sure that the maximum permissible number of starts does not exceed 12 starts
per hour.
As soon as the machine is operated under normal operating conditions:
• Measure the motor current and record it as reference for future maintenance and
troubleshooting work.
6.1 Conveying Condensable Vapours
Water vapour within the gas flow is tolerated within certain limits. The conveyance of
other vapours shall be agreed upon with Busch.
In order to use the machine for the conveyance of condensable vapours, the machine
must be equipped with a corrosion protection coating (Aqua version) and a drain cock in
the silencer.
If condensable vapours are to be conveyed:
Before process:
• Warm up the machine for approximately half an hour.
After process:
• Operate the machine for approximately another half an hour.
• Regularly drain condensate from the silencer with the drain cock.

7 Maintenance
WARNING
Machines contaminated with hazardous material.
Risk of poisoning!
Risk of infection!
If the machine is contaminated with hazardous material:
• Wear appropriate personal protective equipment.
CAUTION
Hot surface.
Risk of burns!
• Prior to any action requiring touching the machine, let the machine cool down first.
• Shut down the machine and lock against inadvertent start up.
• Vent the connected lines to atmospheric pressure.
If necessary:
• Disconnect all connections.
7.1 Maintenance Schedule
The maintenance intervals depend very much on the individual operating conditions. The
intervals given below are desired to be considered as starting values which should be
shortened or extended as appropriate. Particularly heavy duty operation, such as high
dust loads in the environment or in the process gas, other contamination or ingress of
process material, can make it necessary to shorten the maintenance intervals significantly.
Monthly In case of an inlet filter being installed:
• Check the inlet filter cartridge, replace if necessary.
Every 3 months
• Check the oil level, see Oil Level Inspection [}11].
Every 6 months • Clean the machine from dust and dirt.
Every 20000 hours • Change the oil.
The change interval of 20000 operating hours is valid
for Busch approved oils only. The change interval depends very much on the operating conditions. Borderline operation may reduce the change interval down to
approximately 5000 operating hours. Other oils may reduce the change interval.
Every 6 years • Have a major overhaul on the machine (contact
Busch).
7.2 Oil Level Inspection
• Shut down the machine.
• When the machine is stopped, wait 1 minute before checking the oil level.
