The gas conveyed by the vacuum pump smells
displeasing

Process components evaporating under vac-
uum

Readily volatile and thus gaseous components
of the oil, e.g. additives, particularly right after
an oil change.

Note

: This is no indication of a malfunction of

the oil separator. The oil separator is able to
retain droplets of oil, however no gaseous
components of it.

Check the process, if applicable

Use a different type of oil, if applicable

The vacuum pump does not start

The drive motor is not supplied with the cor-
rect voltage or is overloaded

Supply the drive motor with the correct volt-
age

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

One of the fuses has blown

Check the fuses

Version with alternating current motor:

The drive motor capacitor is defective

Repair the drive (Busch service)

The connection cable is too small or too long
causing a voltage drop at the vacuum pump

Use sufficiently dimensioned cable

The vacuum pump or the drive motor is
blocked

Make sure the drive motor is disconnected
from the power supply

Remove the fan cover

Try to turn the drive motor with the vacuum
pump by hand

If the vacuum pump is blocked:

Repair the vacuum pump (Busch service)

The drive motor is defective

Replace the drive motor (Busch service)

The vacuum pump is blocked

Solid foreign matter has entered the vacuum
pump

Repair the vacuum pump (Busch service)

Make sure the suction line is equipped with a
screen

If necessary additionally provide a filter

Corrosion in the vacuum pump from remain-
ing condensate

Repair the vacuum pump (Busch service)

Check the process

Observe the chapter Conveying Condensable
Vapours (

 

page 8)

Version with three-phase motor:

The vacuum pump was run in the wrong di-
rection

Repair the vacuum pump (Busch service)

When connecting the vacuum pump make
sure the vacuum pump will run in the correct
direction (

 

page 6: Installation)

After shutting down the vacuum pump the
vacuum system exerted underpressure onto
the pump chamber which sucked back exces-
sive oil from the oil separator into the pump
chamber

When the vacuum pump was restarted too
much oil was enclosed between the vanes

Oil could not be compressed and thus broke a
vane

Repair the vacuum pump (Busch service)

Make sure the vacuum system will not exert
underpressure onto the shut-down vacuum
pump, if necessary provide an additional
shut-off valve or non-return valve

After shutting down the vacuum pump con-
densate ran into the pump chamber

When the vacuum pump was restarted too
much condensate was enclosed between the
vanes

Condensate could not be compressed and
thus broke a vane

Repair the vacuum pump (Busch service)

Make sure no condensate will enter the
vacuum pump, if necessary provide a drip leg
and a drain cock

Drain condensate regularly
