Maintenance
Troubleshooting
Pump runs, but fluid does not
come out
or flow decreased, or stop.
The suction lift or discharge head is too long Confirm the piping configuration and shorten the length.
The suction-side fluid piping (including the strainer) is
clogged with slurry or sludge
Check and clean the fluid piping and filters (if fitted).
The supply air pressure is low
Raise the supplied air pressure to the pump. Check the
compressor and regulator settings and check that the
configuration of the air piping is correct.
Cavitation occurs
Adjust the correlation between supply air pressure inlet
and discharge flow or pressure, or shorten the suction
lift length.
Chattering occurs (ball valves not seating properly)
Check and adjust the correlation between supplied air
pressure and inlet pressure and discharge pressure or
flow. Decrease the inlet flow rate or increase the back
pressure by slightly closing the discharge valve. Check
the ball valve material is sufficiently heavy compared to
the liquid being pumped.
Icing on air-switching portion
Check that the air filter and exhaust are clean and not
blocked or restricted. Check and adjust the air flow rate
and the correlation between the liquid flow rates. Fit a
speed control muffler. Manually remove ice from air-
switching valve before restarting.
The exhaust port (silencer) of pump is clogged with
sludge. Or the air filter is blocked
Check and clean the exhaust port or replace the
silencer. Check and replace the air filter as necessary.
Problem Probable Cause Actions to be taken
Pump does not run
The exhaust port (silencer) of pump is clogged with
Dirt or sludge.
Check and clean the exhaust port or replace the
silencer.
Air is not supplied
Start the compressor, open the airline ball valve and
air Regulator. Check functionality of solenoid valves (if
fitted).
The supplied air pressure is too low
Raise the supplied air pressure to the pump. Check the
compressor and regulator settings and check that the
configuration of the air piping is correct.
The spool stopped in neutral position Press the RESET button.
