Exchange

Coupling defective

Repair and/or exchange

Starting temperature too low

User

Put vacuum pump in a warm 
place corresponding to the 
starting temperature

Oil is resinous after too long storage

User or  
Service  
workshop

General maintenance /  
cleaning

Vacuum pump 
does not  
generate  
a vacuum

Ultimate pressure few mbar or atmospheric  
pressure, oil shortage

User

Top-up oil

Oil is dirty

Operate with gas ballast, 
or perform oil change with 

flushing

Oil supply to pump unit interrupted or reduced

Check that the oil circulation 
is functioning, measure the  
oil pressure at operating  
temperature, 1 – 1.2 bar 
overpressure, check that  
the pipes are clear and  
have no leaks

Gas ballast valve open

Close the gas ballast valve

Shaft seals defective

User or  
Service  
workshop

Exchange

Work or pressure control valve defective

Intake valve defective

Repair

Oil supply to pump aggregate reduced,  
Oil superimposition interrupted by work valve

Built-up pressure in the oil casing too high  

because of exhaust gas pipe or oil mist filter

Check exhaust pipe,  

change filter insert
