The vacuum pump starts, but labours or runs
noisily or rattles
The drive motor draws a too high current
(compare with initial value after commission-
ing)
Loose connection(s) in the drive motor termi-
nal box
Version with three-phase-motor:
Not all drive motor coils are properly con-
nected
The drive motor operates on two phases only
Check the proper connection of the wires
against the connection diagram
Tighten or replace loose connections
Version with three-phase motor:
The vacuum pump runs in the wrong direction
Verification and rectification page 5: Instal-
lation and Commissioning
Standstill over several weeks or months Let the vacuum pump run warm with inlet
closed
Oil viscosity is too high for the ambient tem-
perature Use synthetic oil, if necessary use oil of the
next lower viscosity class (CAUTION: opera-
tion with too low viscosity can cause chatter
marks inside the cylinder)
Warm up the oil with a heater prior to starting
up the vacuum pump, or run the vacuum
pump in intervals in order not to let it get too
cold
Improper oil quantity, unsuitable oil type Use the proper quantity of one of the recom-
mended oils
( page 17: Oil change: page 8: Mainte-
nance)
No oil change over extended period of time Perform oil change incl. flushing
( page 8: Maintenance)
The exhaust filter is clogged and appears black
from burnt oil Flush the vacuum pump
Replace the exhaust filter
Fill in new oil
( page 8: Maintenance)
In case the oil life is too short: use oil with
better heat resistance (
page 17: Oil) or ret-
rofit cooling
Foreign objects in the vacuum pump
Broken vanes
Stuck bearings
Repair the vacuum pump (Busch service)
The vacuum pump runs very noisily Defective bearings Repair the vacuum pump (Busch service)
Stuck vanes Repair the vacuum pump (Busch service)
Use only recommended oils ( page 17: Oil)
and change more frequently
The vacuum pump runs very hot
(the oil sump temperature shall not exceed
100 °C)
Insufficient air ventilation Make sure that the cooling of the vacuum
pump is not impeded by dust/dirt
Clean the fan cowling, the fan wheel, the ven-
tilation grille and the cooling fins
Install the vacuum pump in a narrow space
only if sufficient ventilation is ensured
On a vacuum pump with oil-cooler: clean the
intermediate spaces of the finned tube
Ambient temperature too high Observe the permitted ambient temperatures
Temperature of the inlet gas too high Observe the permitted temperatures for the
inlet gas
The exhaust filter is partially clogged Replace the exhaust filter
Not enough oil in the reservoir Top up oil
