Product Description

Use

The vacuum pump is intended for

–

the suction

of

–

air and other dry, non-aggressive, non-toxic and non-explosive
gases

Conveying media with a lower or higher density than air leads to an in
creased 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 (Ú page 8: 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 vacuum pump is intended for the placement in a non-potentially
explosive environment.

Vacuum pumps MM 1324 AV standard-version are thermally suitable
for continuous operation down to ultimate pressure.

Vacuum pumps MM 1324 AV Version “Aqua” 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.

Vacuum pumps MM 1202 AV, MM 1200 AV, MM 1252 AV and
MM 1250 AV are thermally suitable for continuous operation at intake
pressures down to 100 hPa abs (100 mbar abs). By means of process
control and/or vacuum relief valves it must be made sure that the mini
mum allowed intake pressure will not be underrun.

Vacuum pumps MM 1322 AV and MM 1320 AV are thermally suitable
for continuous operation at intake pressures down to 150 hPa abs
(150 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.

Version “Aqua”:

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 cylin
der, on the other hand the gaps are small enough to keep the clear
ance loss between the chambers low.

In order to avoid the suction of solids, the vacuum pump is equipped
with a screen (715) in the suction connection.

In order to avoid reverse rotation after switching off, the vacuum
pump is equipped with a non-return valve (n, 714).

The vacuum pump compresses the inlet gas absolutely oil-free. A lubri
cation of the pump chamber is neither necessary nor allowed.

Conservation

In case of adverse ambient conditions (e.g. aggressive atmosphere, fre
quent temperature changes) conserve the vacuum pump 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 mo
lecular thickness on the packed good and by its electro-chemical prop
erties 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.

gases

Conveying media with a lower or higher density than air leads to an in
creased 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 (Ú page 8: 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 vacuum pump is intended for the placement in a non-potentially
explosive environment.

Vacuum pumps MM 1324 AV standard-version are thermally suitable
for continuous operation down to ultimate pressure.

Vacuum pumps MM 1324 AV Version “Aqua” are thermally suitable

●

Prerequisites) are complied with and will remain complied with,
particularly that a sufficient cooling will be ensured

Conveying Condensable Vapours

Version “Aqua”:

CAUTION_a

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 (j).

◆

Close the shut-off valve in the suction line

◆

Warm up the vacuum pump for approx. 10 minutes

At process start:

◆

Open the shut-off valve in the suction line

At the process end:

◆

Close the shut-off valve in the suction line

◆

Open the ambient air valve

◆

Operate the vacuum pump for another approx. 10 minutes

◆

Close the ambient air valve

◆

Regularly drain condensate from the anti-pulsation chamber (j)

terial can reside in filters.

Danger to health during inspection, cleaning or replacement of fil
ters.

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.

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

In case an inlet air filter (h) is installed:

◆

Check the inlet air filter (h), if necessary clean (with com
pressed air) or replace

Every 3 Months:

●

Make sure that the vacuum pump is shut down

●

Check the level of the synchronising gear oil

The level shall be slightly above the middle of the sight glass (e, 76).

The level of the synchronising gear should stay constant over the life
time of the oil. If the level does fall, the gear is leaky and the vacuum
pump requires repair (Busch service).

Every 6 Months:

●

Make sure that the housing is free from dust and dirt, clean if nec
essary

●

Make sure that the vacuum pump is shut down and locked against
inadvertent start up
