thermal insulation (Oil in page 22) or replace cooling
system
Foreign matters in the pump, damaged vane (22) or
bearing
Repair the vacuum pump (Greenco service)
The vacuum pump runs very noisily
Defective bearings Repair the vacuum pump (Greenco service)
Worn coupling element (310) Replace the coupling element (310)
Stuck vanes (22)
Repair the vacuum pump (Greenco service)
Use only approved oils (see “Oil” in page 22) and change
more frequently
The vacuum pump runs very hot
(the oil sump temperature shall not exceed
100
℃
)
Insufficient air ventilation
Make sure that the cooling of the vacuum pump is not
impeded by dust/dirt
Clean the fan cowlings, fan wheels, ventilation screens
and 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(l20) is partially clogged Replace the exhaust filters (120)
The oil filter (100) is partially clogged
(the oil flows through the bypass only, the oil does
not get filtered any more)
Replace the oil filter (100)
(see “Maintenance” in page 8)
Not enough oil in the reservoir
Top up oil
Oil burnt from overheating
Flush the vacuum pump
Replace the oil filter (100)
Replace the exhaust filters (120)
Fill in new oil
(see “Maintenance” in page 8)
In case the oil life is too short: use oil with better heat
resistance (see “Oil” in page 22)or retrofit cooling
Mains frequency or voltage outside tolerance range Provide a more stable power supply
The mesh screen or filter clogged.
The suction connection, discharge or pressure pipe
clogged
Remove the clogging
Long suction, discharge or pressure line with- too
small diameter
Use larger diameter
The vacuum pump fumes at the exhaust
side or expels oil droplets through the
outlet
The oil level drops
The exhaust filters (120) are not properly seated
Check the proper position of the exhaust filters (120)
(see “Maintenance” in page 8)
The O-rings from the exhaust filters are missing or
damaged
Add or replace the O-rings
(see “Maintenance”in page 8)
The exhaust filters (120) show cracks Replace the exhaust filters (120
(see “Maintenance”in page 8)
The exhaust filters (120) are clogged with fo- reign
matter
NOTE: The saturation of the exhaust filters- with oil
is no fault and does not impair the function of the
exhaust filters! Oil dropping down from the exhaust
filters is returned to the oil circulation.
Replace the exhaust filters (120)
(see “Maintenance” in page 8)
Version with oil return valve (280): if pump
continuously run
Note: oil separator shows no fault; oil returns to oil
Periodically turn off vacuum pump and check the oil
return valve (280)
