TROUBLESHOOTING

PROBLEM

CAUSES

SOLUTION

Insufficient

pumping

capacity

Clogged inlet filter and/or strainer

Clean or change the inlet filter and/or strainer

Too much clearance

Check the screw “E” clearance and reset the 

clearance (reset the timing gear)

Motor 

Overload

Clogged inlet filter and/or strainer

Clean or change the inlet filter and/or strainer

Foreign matter is caught in the pump

Check the screw “E” clearance and reset (reset the 

timing gear) if needed.  If the screws and/or casing 

are damaged by foreign material, replace the screw 

and/or casing.

Significant increase of inlet pressure

Check the pressure differential between the inlet and 

outlet of the pump

Interference between screws

Reset the screw “E” clearance (reset the timing gear

Interference between screws and casing

Reset the “D” clearance.

Blocked discharge nozzle or piping and increased 

back pressure

Drain & clean discharge nozzle and piping

Overheat

Excessive oil in FEC

Check oil level and adjust the oil level if required

High vacuum pump inlet temperature

Reduce the inlet temperature

High compression ratio

Check the differential pressure between inlet and 

discharge nozzle

Interference between screw and casing

Search for the cause of interference

Problem with cooling liquid flow

Clean cooling liquid lines and pump cooling jackets

Blocked discharge nozzle or piping and increased 

back pressure

Drain and clean discharge nozzle and piping

Knocking

Incorrect positioning of timing gears and screws

Reposition the timing gears and screws:  run-out or 

flatness of the timing gears should be within 0.03 mm

Improper assembly

Reassemble the pump

Abnormal rise of inlet pressure

Search for the cause

Damaged gear due to overload or improper 

lubrication

Replace timing gears

Bearing or 

gear damage

Improper lubrications

Change oil

Low oil level

Refill oil to the correct level

NOTE:  If the troubles are not resolved by the above actions, the cause may be the Pump Operating condition.  In that case, 

please contact us with the following information:

 

1.  Model Name and Number, Serial Number, Application, etc.

 

2.  Piping Information (Valves, Stainer, Number of Bends, etc.)
