6.1  Pump Malfunctions

Malfunction

Likely cause

Remedy

Pump does not start 
up. 

EF2, EF3 

or 

100FT

is displayed at the fre-
quency converter  
(see Section 6.2)

Motor incorrectly connected.
Overtemperature switch or motor stator  

defective.
Pressure switch is defective.
Lubricant is too thick. 

Motor rotor defective.
Pump has seized: defective impellers, bearings or 

toothed gears.

Connect motor correctly.
Leybold Service. 

Replace the pressure switch.
Exchange the lubricant or warm up lubricant 

and pump.
Leybold Service.
Leybold Service.

Pump gets too hot.

PT1000 

or 

dwFL

is displayed at the fre-
quency converter  
(see Section 6.2)

Cooling water supply is not sufficient.
Cooling water lines are clogged.
Filter insert in the pressure reducer is clogged.
Ambient temperature is too high or cooling air flow is 

obstructed. 
Pump is operating in the wrong pressure range. 
Gas temperature is too high. 
Clearance between housing and rotors are too small 

due to 

- contamination  

- distortion of the pump 
Friction resistance is too high due to contaminated 

bearings and/or contaminated lubricant.
Lubricant level is too high. 
Lubricant level is too low. 
Wrong lubricant filled in. 
Bearing is defective.

Ensure sufficient cooling water supply.
Decalcify cooling water lines.
Clean filter insert.
Install the pump at a suitable place or ensure a 

sufficient flow of cooling air.
Check the pressure levels within the system.
Check system. 
Clean pumping chamber.  

Affix and connect the pump free of tension. 

 

Clean pump, respectively perform maintenance.
 

Drain lubricant down to the correct level.
Top up lubricant to the correct level. 
Leybold service
Leybold Service.

Pump is extremely 

loud.

Bearing damage.
Thick particle deposits.
Defective silencer.
High gas throughput with the discharge line open, 

without silencer.

Repair pump.
Clean pump, respectively perform maintenance.
Repair silencer.
Install discharge line or silencer.

Motor power con-

sumption is too high. 

Like „Pump gets too hot“. 
Incorrect mains voltage for the motor.

Like malfunction „Pump gets too hot“. 
Connect the motor to the correct mains voltage.

Pump is too loud.

Motor stator defective. 
Motor rotor defective. 
Distances between housing and rotors is too small 

due to 

- contamination 

- distortion of the pump 
Bearing or gear damage. 
Pistons make contact with the housing.
Rotor is running untrue. 
Oil slinger disc makes contact with the gear housing 

or the oil pipe.
Oil pump is blocked or defective.
