Commissioning” in page 5 ， correct if necessary
Standstill over several weeks or months Let the vacuum pump run warm with inlet closed
Oil viscosity is too high for the ambient temperature
Use synthetic oil, if necessary use oil of the next lower
viscosity class (CAUTION: operation with too low
viscosity can cause chatter marks inside the cylinder)
Warm up the oil with a heating prior to starting up the
vacuum pump or, make sure that the vacuum pump runs
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 recommended oils
(see “Oil” in page 22,
Oil change see “Maintenance”)
Over ten hours, the oil accumulates in the upper
chamber of oil separator (75); it can spill out along
with the gas discharged when it reaches a certain
amount
If it is intact, and help the oil flow from the upper chamber
of oil separator (75) to the bottom chamber after the
pump is shut down (Oil circulation in page 3)
For the pump equipped with oil return valve (280):
oil return valve stop working or clogged (correct
operation mode: oil flows into the oil return valve,
and it closes; the vacuum generates and it opens.
Note: do not suck the oil return valve with mouth0
Clean or replace oil return valve (280)
For the vacuum pump equipped with float valve
(200) and oil return pipe: float valve (200) stuck at
opening
Roll the float valve (200) or replace it when necessary
(Checking float valve in page 10)
Oil return pipe (195) clogged or damaged
Clean the clogged oil return pipe (195); replace the
damaged oil return pipe (195); and fill in oil (request
service from Greenco when necessary)
The oil is black
Oil change intervals are too long
The oil was overheated
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
The oil is watery and coloured white
The vacuum pump aspirated water or significant
amounts of humidity
For the vacuum pumps equipped with gas ballast:
clogged filter cartridge
Flush the vacuum pump
Replace the oil filter(100)
Replace the exhaust filters (120)
Flush the vacuum pump
(see “Maintenance”in page 8)
Modify the operational mode
(see “Installation and Commissioning, Operating Notes,
Conveying Condensable vapors”in page 8)
For the pump equipped with gas ballast (440): replace
filter
The oil is resinous and/or sticky Improper oil type, perhaps in confusion
Flush the vacuum pump
Replace the oil filter(100)
Replace the exhaust filters (120)
Fill in new oil
(see “Maintenance”in page 8)
Make sure the proper oil is used for the application
The oil foams Mixing of incompatible oils
Flush the vacuum pump
Replace the oil filter(100)
Replace the exhaust filters (120)
Fill in new oil
(see “Maintenance” in page 8)
Make sure the proper oil is used for the application
