Failure Mode
Possible Cause
Remedy
Pump stops
working
a) Motive supply closed
a) Open valves to supply motive
pressure to pump
b) Motive line strainer chocked
b) Clean the strainer
c) Condensate inlet line closed
c) Open condensate inlet valve and
allow condensate to flow in
pumping chamber.
d) Condensate line strainer
chocked
d) Clean the strainer.
e) Condensate discharge line
closed
e) Open all discharge line valves to
allow free discharge from pump to
destination.
f) Motive pressure insufficient to
overcome back pressure
f) Check motive and back pressure.
Adjust motive pressure to 2barg
more than total back pressure.
g) Float punctured
g) Replace the float.
h) Check the direction of the
Check Valve
h) Correct it if found wrong.
i) Steam coming out continuously
from exhaust line
i) It means motive steam inlet valve is
leaking- open the internals and
clean the inlet valve. Replace it if
found damaged.
j) Exhaust valve leaking
j) Open the pump internals and clean
it. Also check the setting of valve
actuator disc and correct it if found
disturbed.
