2.1 Operating Principle
Compression cycle
Position 1
Position 4 Position 3
Position 2Position 5
Gas inlet (IN)
Gas outlet (OUT)
Fixed scroll
Orbiting scroll
Gas process pocket
Scroll vacuum pumps consist of both a fixed and an orbiting scroll. As the orbiting scroll
moves, voids are created at the inlet of the pump, drawing in the gas. As the rotor fur-
ther moves, the gas is steadily compressed until it is discharged to atmosphere at the
pump exhaust.
The compression is made without the use of any lubrication whatsoever.
NOTICE
Lubricating a dry running machine (compression chamber).
Risk of damage to the machine!
• Do not lubricate the compression chamber of the machine with oil or grease.
2.2 Application
The machine is intended for the suction of air and other dry, toxic, non-aggressive 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.
Depending on the optional variant, the machine may be used for ATEX or oxygen appli-
cations, see Optional Variants [►7].
The machine is gas tight when a gas ballast valve is not installed.
The machine is suitable for continuous operation.
The continuous operation of FO 0035 B is limited to a suction pressure of 100 hPa
(mbar) abs..
Permitted environmental conditions, see Technical Data [►20].
The machine is capable of conveying gases which contain a certain percentage of water
vapour if the gas ballast valve (accessory) is installed and open. See chapters Conveying
Condensable Vapours [►14] and Technical Data [►20].

2.3 Standard Features
2.3.1 Non-return Valve
The non-return valve (NRV), integrated to the discharge connection (OUT), protects the
process against suckback.
2.3.2 Inlet Screen
The inlet screen (IS), integrated to the suction connection (IN), prevents large solid parti-
cles from entering into the machine.
2.3.3 Operating Hours Counter
The opperating hours counter allows the reading of the total operating time that the ma-
chine has run.
2.3.4 Variable-Frequency Drive (Single-phase Version Only)
The machine is equipped in standard with a variable-frequency drive.
2.3.5 I/O and Communication Port (Single-phase Version Only)
The D-Sub 9 supports maintained dry contact remote control and monitoring of the ma-
chine.
2.4 Optional Accessories
2.4.1 Inlet Filter
2.4.2 Exhaust Filter
The exhaust filter reduces the exhaust noise and retains the tip seal dust when the ma-
chine cannot be connected to a house exhaust system.
2.4.3 Gas Ballast Valve
The gas ballast valve mixes the process gas with a limited quantity of ambient air to
counteract the condensation of vapour inside the machine.
2.4.4 Purge Gas Adapter
The purge gas adapter can be fitted in place of the gas ballast valve. It allows you to
connect a controlled supply of inert gas to the pump.
2.4.5 Wheels
Four wheels can easily be fitted to the bottom of the machine to facilitate transportation
and installation.

2.5 Optional Variants
2.5.1 ATEX (Optional)
According to ATEX classification, refer to the nameplate (NP), explosive gases and va-
pour mixtures (zone 2) can be drawn in according to the scope of the Directive ATEX
2014/34/EU.
2.5.2 Oxygen (Optional)
The machine is designed for conveying gases with an increased oxygen content (volume
content greater than 21% and up to 100%) if the following label is stuck on the ma-
chine body:
3 Transport
WARNING
Suspended load.
Risk of severe injury!
• Do not walk, stand or work under suspended loads.
• Make sure that the eyebolt(s) (EB) is/are in faultless condition, fully screwed in and
tightened by hand.
Machine weight:
see the technical data 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
8 / 28 Instruction Manual FOSSA FO 0015 A - FO 0035 B_EN_en
4 Storage
• Seal all apertures with adhesive tape or reuse provided caps.
NOTICE
Long storage time.
Risk of damage to the machine!
• Due to a long storage time the capacitors of the variable speed drive can lose efficien-
cy because of electrochemical processes. In the worst case, it can lead to a short-cir-
cuit and therefore to a damage to the variable speed drive of the machine.
• Connect the machine every 18 months for 30 minutes to the mains.
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 ... 60 °C.

• Make sure that the ambient conditions comply with the Technical Data [►20].
• 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.
• Make sure that enough space remains for maintenance work.
• Make sure that all provided covers, guards, hoods, etc. are mounted.
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.
If additional electrical components not included in scope of delivery should be added:
• Make sure that they have a better or equal ATEX classification than that of the
machine, see the ATEX marking on the nameplate (NP).
5.2 Connecting Lines / Pipes
WARNING
The connection lines can build up an electrostatic charge.
Risk of severe injury!
Risk of explosion!
• The connection lines must be made out of conductive material or provisions must be
made against creating an electrostatic charge.
• 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.

7 | Maintenance
16 / 28 Instruction Manual FOSSA FO 0015 A - FO 0035 B_EN_en
7.1 Maintenance Schedule
The maintenance intervals depend very much on the individual operating
conditions. The intervals given below are considered as starting values
which should be shortened or extended as appropriate. Particularly harsh
applications or 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.
Interval Maintenance work
Every 6 months or as required • Clean the machine from dust and dirt.
• Check the inlet screen (IS), clean if necessary.
• Flush the machine by running it at atmospheric pres-
sure for about 1 minute.
In case of an inlet filter being installed:
• Check the inlet filter cartridge, clean if necessary.
In case of a gas ballast valve being installed:
• Clean the filter of the gas ballast valve.
Annually or as required • Replace the tip seal and the non-return valve (NRV),
see Tip Seal and Non-return Valve Replacement
[►16].
Every 4 years, the latest after
20000 hours
• Have a major overhaul on the machine (contact
Busch).
7.2 Tip Seal and Non-return Valve Replacement
NOTICE
Changing the tip seals without training.
Loss of Busch liability!
Loss of efficiency!
• Ask your Busch representative before performing this maintenance task.
• Order the Busch genuine service kit.
• Follow the service instructions (document ref. 0870 202 845) delivered with the ser-
vice kit (see Spare Parts) before performing this maintenance task.
