Product Description
Use
The vacuum pump is intended for
−the suction
of
−mixtures of dry non-aggressive and non-toxic gases and/or
dust according to the identification on the nameplate of the
vacuum pump (explanation see below).
Conveying media with a lower or higher density than air leads to an
increased thermal and/or mechanical load on the vacuum pump and
is permissible only after prior consultation with Busch.
Max. allowed temperature of the inlet gas: 40 °C
Standard-version:
The gas shall be free from vapours that would condensate under
the temperature and pressure conditions inside the vacuum
pump.
Version “Aqua”:
The vacuum pump features the corrosion protection coating CPC
and is capable of conveying water vapour ➔ page 9: Conveying
Condensable Vapours). Conveyance of other vapours shall be
agreed upon with Busch. Conveyance of water or other liquids in
liquid phase increases the power consumption and shall therefore
be avoided (risk of drive overload).
The classification on the vacuum pump is to be read as follows
(interpretations of equipment categories and zones for information
only; the relevant laws, directives and standards are literally binding;
for temperature classes and explosion groups see E. Brandes,
W. Möller “Sicherheitstechnische Kenngrößen, Band 1: Brennbare
Flüssigkeiten und Gase”, ISBN 3–89701–745–8 (or equivalent
source)):
II 3(i) D 125°C
Group II, for non-mining applications,
in the process gas explosive atmosphere in the form of a cloud of
combustible dust in air not likely to occur in normal operation but, if it
does occur, will persist for a short period only (equipment
category 3, for zone 22);
maximum permissible surface temperature for the dust/air mixture in
the process gas greater equal 125 °C (acc. to EN 50281-2-1 or IEC
61241-2-1 resp.).
Not for explosive atmospheres consisting of mixtures with air of
flammable substances in the form of gas.
Not for potentially explosive atmospheres in the environment.
The use of the supplied inlet air filter (c) with equipotential
bonding (d) including the pertinent filter cartridge with equipotential
bonding is required.
The approval for use in potentially explosive atmospheres is
valid for the vacuum pump together with the supplied inlet air
filter (c). The approval is void if the system is altered or if the
scheduled maintenance is not complied with. Maintenance
must be performed by specifically instructed personnel only.
Max. permissible number of startings per hour: 12
Vacuum pumps MV 0502/0602 B ATEX are thermally suitable for
continuous operation.
Version “Aqua”:
Vacuum pumps MV 0502/0602 B “Aqua” version are thermally
suitable for continuous operation at intake pressures down to 200
hPa abs (200 mbar abs). By means of process control and/or
vacuum relief valves it must be made sure that the minimum
allowed intake pressure will not be underrun.
The safety valve on the vacuum pump protects the vacuum pump
against overheating only. It is not designed for frequent use and
must therefore not be used as a system pressure regulating valve.

Principle of Operation
The vacuum pump works on the claw principle.
The components are dimensioned such, that on the one hand there
is never contact between the two claws or between a claw and the
cylinder, on the other hand the gaps are small enough to keep the
clearance loss between the chambers low.
In order to avoid the suction of solids, the vacuum pump is equipped
with a screen in the suction connection.
In order to avoid reverse rotation after switching off, the vacuum
pump is equipped with a non-return valve.
The vacuum pump compresses the inlet gas absolutely oil-free. A
lubrication 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 air flow from the fan wheel of the drive motor
−the process gas
−the air flow from the fan wheel on the shaft of the vacuum
pump
Start Controls
The vacuum pump comes without start controls. The control of the
vacuum pump is to be provided in the course of installation.

immediately. In case of favourable ambient conditions conserve the
vacuum pump if a storage of more than 3 months is scheduled.
•Make sure that all ports are firmly closed; seal all ports that are
not sealed with PTFE-tape, gaskets or o-rings with adhesive
tape
Note: VCI stands for “volatile corrosion inhibitor”. VCI-products (film,
paper, cardboard, foam) evaporate a substance that condenses in
molecular thickness on the packed good and by its electro-chemical
properties effectively suppresses corrosion on metallic surfaces.
However, VCI-products may attack the surfaces of plastics and
elastomers. Seek advice from your local packaging dealer! Busch
uses CORTEC VCI 126 R film for the overseas packaging of large
equipment.
•Wrap the vacuum pump in VCI film

Maintenance Schedule
Note: The maintenance intervals depend very much on the
individual operating conditions. The intervals given below shall be
considered as starting values which should be shortened or
extended as appropriate.
Particularly heavy duty operation, such like high dust loads in the
environment or in the process gas, other contaminations or ingress
of process material, can make it necessary to shorten the
maintenance intervals significantly.
Monthly
•Make sure that the vacuum pump is shut down and locked
against inadvertent start up
•Check the inlet air filter (c), if necessary replace
In case of operation in a dusty environment:
♦Clean as described under ➔ page 9: Every 6 Months
CAUTION
Due to the corrosion protection coating CPC the vacuum pump
is capable of conveying water vapour.
Very humid process gases and/or adverse operating cycles can
lead to residual condensates, though, which cause corrosion.
If this is the case, it is necessary to counteract residual
condensates by warming up the vacuum pump, conveyance of
ambient air after process end and regular draining of the anti-
pulsation chamber
WARNING
The approval of the vacuum pump for use in potentially
explosive areas remains valid only if the maintenance is
conducted regularly according to the maintenance
schedule below and genuine spare parts and consumables,
approved for use in potentially explosive areas by Busch,
are used exclusively.
Maintenance work must be executed by qualified
personnel, specially instructed in the maintenance of this
type of vacuum pump by Busch.
CAUTION
During operation the surface of the vacuum pump may reach
temperatures of more than 70 °C.
Risk of burns!
DANGER
In case the vacuum pump conveyed gas that was
contaminated with foreign materials which are dangerous
to health, harmful material can reside in filters.
Danger to health during inspection, cleaning or
replacement of filters.
Danger to the environment.
Personal protective equipment must be worn during the
handling of contaminated filters.
Contaminated filters are special waste and must be
disposed of separately in compliance with applicable
regulations.
CAUTION
The vacuum pump emits noise of high intensity in a narrow

Troubleshooting
Problem Possible Cause Remedy
The vacuum pump does not reach the usual
pressure
The drive motor draws a too high current
(compare with initial value after
commissioning)
Evacuation of the system takes too long
The vacuum system or suction line is not leak-
tight Check the hose or pipe connections for possible leak
In case a vacuum relief valve/regulating
system is installed:
The vacuum relief valve/regulating system is
misadjusted or defective
Adjust, repair or replace, respectively
The screen in the suction connection is
partially clogged Clean the screen If cleaning is required too frequently install a
filter upstream
The filter on the suction connection is partially
clogged Clean or replace the inlet air filter, respectively
Partial clogging in the suction, discharge or
pressure line Remove the clogging
Long suction, discharge or pressure line with
too small diameter Use larger diameter
The valve disk of the inlet non-return valve is
stuck in closed or partially open position Disassemble the inlet, clean the screen and the valve as required and reassemble
Internal parts are worn or damaged Repair the vacuum pump (Busch service)
The gas conveyed by the vacuum pump
smells displeasing Process components evaporating under vacuum Check the process, if applicable
The vacuum pump does not start The drive motor is not supplied with the
correct voltage or is overloaded Supply the drive motor with the correct voltage
The drive motor starter overload protection is
too small or trip level is too low Compare the trip level of the drive motor starter overload protection with the data on the
nameplate, correct if necessary
In case of high ambient temperature: set the
trip level of the drive motor starter overload
protection 5 percent above the nominal drive
motor current
The connection cable is too small or too long
causing a voltage drop at the vacuum pump Use sufficiently dimensioned cable
CAUTION
During operation the surface of the vacuum pump may reach temperatures of more than 70 °C.
Risk of burns!
Let the vacuum pump cool down prior to a required contact or wear heat protection gloves.
WARNING
Risk of electrical shock, risk of damage to equipment.
