Probable Cause
Pump
is
filled with
lubricating fluid beyond
its capacity.
Negative pressure is
too high.
Filter
is
clogged.
Pump is running
continuously at greater
than 112 Torr.
Valve
(17)
is
open.
Motor
is
rotating

and coupling
housing
(11)
is worn.
Front end plate radial
shaft seal
(45)

Rear end plate radial
shaft seal
(45)
is worn.
Inert gas pressure
in
purge line of modified
pumps is too high.
Drain excess lubricating fluid.
Adjust negative pressure exhaust system.
+ Clean filter or install new filter.
Modify system to run at lower pressure or
use larger pump
model.
Close
valve
(17)
or install
SE
smoke
eliminator or AF exhaust filter with oil

(9).
Replace seal
(13).
Install new seal and check if the exhaust line
is
too narrow or if
an
