NOTE
Illustrations
In this instruction manual the illustrations may differ from the machine appearance.
2.1 Operating Principle
The machine works on the Booster blower principle.
The two oil housings (on each side) allow the lubrication of the gears and bearings.
A bypass valve (BPV) limits automatically the differential pressure between inlet and outlet.
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 vacuum booster is used in combination with a backing pump in vacuum system.
The machine is suitable for continuous operation.
Permitted environmental conditions, see Technical Data [➔30].
NOTICE
Chemical compatibility of the process gases with the machine component materials.
Risk of corrosion inside the compression chamber which can reduce performance and its
lifetime!
●Check if the process gases are compatible with those following materials:
- Cast iron
- Steel
- Aluminium
- Epoxy resin
- Fluoroelastomer (FKM/FPM)
●In doubt, please contact your Busch representative.

2.3 Standard Features
2.3.1 Water Cooling
The machine is driven by a water-cooled motor.
2.3.2 Temperature Switch
The temperature switch monitors the oil temperature of the machine.
The machine must be stopped when the temperature switch trips (140 °C).

3 Transport
WARNING
Suspended load.
Risk of severe injury!
●Do not walk, stand or work under suspended loads.
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 shown.
NOTICE
In case the machine is already filled with oil.
Tilting a machine that is already filled with oil can cause large quantities of oil to ingress into
the cylinder.
●Drain the oil prior to every transport or always horizontally transport the machine.
●To find out the weight of the machine, refer to the chapter Technical Data [➔30] or the
nameplate (NP).
●Check the machine for transport damage.
If the machine is secured to a base plate:
●Remove the machine from the base plate.

4 Storage
●Seal all apertures with adhesive tape or reuse provided caps.
●Make sure that the cooling water has been completely removed, see Decommissioning [➔26].
If the machine is to be stored for more than 3 months:
●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 -20 ... 55 °C.

5.1 Installation Conditions
NOTICE
Use of the machine outside of the permitted installation conditions.
Risk of premature failure!
Loss of efficiency!
●Take care that the installation conditions are fully complied with.
●Make sure that the environment of the machine is not potentially explosive.
●Make sure that the ambient conditions comply with the Technical Data [➔30].
●Make sure to use a suitable backing pump, if necessary seek advice from your Busch
representative
●Make sure that the environmental conditions comply with the protection class of the motor and
the electrical instruments.
●Make sure that the installation space or location is vented such that sufficient cooling of the
machine is provided.
●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
is acceptable.
●Make sure that the machine is secured either from the four feet or from the discharge flange.
●Check the oil level, see Oil Level Inspection [➔21].
●Make sure that all provided covers, guards, hoods, etc. are mounted.
●Make sure that the cooling water complies with the requirements, see Cooling Water Connection
[➔12].
If the machine is installed at an altitude greater than 1000 meters above sea level:
●Contact your Busch representative, the motor should be derated or the ambient temperature
limited.
5.2 Connecting Lines / Pipes
●Remove all protective covers before installation.
●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 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.
