Fault

Possible cause

Remedy

❑

Pump does not

start or stops im-

mediately.

➨

Electrical power cord

not plugged in, electri-

cal supply failure?

✔

Plug in power cord.

Check fuse.

➨

Device fuse blown?

✔

Identify cause of failure.

Replace device fuse.

➨

Overpressure in outlet

line or in the system (at

outlet side)?

✔

Remove blockage in line,

open valve, or reduce

overpressure in the sys-

tem (pressure adjustment

device ME 4R NT).

➨

Motor overloaded?

✔

Allow motor to cool down,

identify and eliminate

cause of failure. Manual

reset is necessary. Switch

off pump or unplug.

❑

Pump does not

achieve its ultimate

vacuum or usual

pumping speed.

➨

Centring ring at small

flange connection not

correctly positioned, or

leak in the pipeline or

vacuum system?

✔

Check pump directly -

connect vacuum gauge

directly at pump inlet -

then check connection,

pipeline and vacuum

system if necessary.

➨

Vacuum adjustment de-

vice open (ME 4R NT)?

✔

Close vacuum adjustment

device.

➨

Long, narrow vacuum

line?

✔

Use lines with larger di-

ameter, length as short as

possible.

➨

Pump has been ex-

posed to condensate?

✔

Allow pump to run for

some minutes with atmo-

spheric pressure at the

inlet to purge.

➨

Deposits have been

formed inside the

pump?

✔

Clean and inspect the

pump heads.

➨

Diaphragms or valves

damaged?

✔

Replace diaphragms and/

or valves.

➨

Outgassing substances

or vapor generated in

the process?

✔

Check process parame-

ters.
