Caution
-The graph of flow-rate characteristics is in the condition of no piping for suction and discharge.
It may not be possible to obtain the discharge in the graph depending on the piping conditions.
In air operated type, the discharge is greatly affected by the piping conditions of pilot air.
-The viscosity of the operating fluid depends on the operating conditions (temperature,
transportation distance).
The viscosity can also vary due to changes in the ambient temperature.
-Fluids of viscosity up to 100 mPa
･
s can be used.
9. Troubleshooting
If any abnormality is found, perform checks according to the following list. If the abnormality
cannot be eliminated, ask SMC.
Warning
-Discharge dangerous fluid from the pump.
-Do not return the pump with dangerous fluid left in it. Otherwise, the fluid could cause burns
and other injuries during transportation. If the product is to be returned, inform SMC or the
distributor beforehand.
Trouble Possible cause Remedy
1)Supply of air cannot move
the pump.
-Operation failure of the solenoid valve. -Replace the solenoid valve
with a new one.
2)The pump
starts, but
does not
discharge
fluid.
The pump
does not
suck fluid.
-The check valve is clogged.
-The check valve is damaged or worn out.
-The filter at suction side (IN port) is
clogged.
-Excessive suction pump head.
-Incorrect mounting direction.
-The diaphragm is damaged or coming
off.
-Sealing failure of fitting at suction side
(IN port).
-Excessive viscosity of transported fluid.
-Cleaning
-Replace the pump.
-Clean the filter.
-Reduce within self suction
capacity.
-Correct to normal mounting
direction.
-Replace the pump.
-Ensure sufficient sealing.
-Non-conformance.
The pump
sucks, but
does not
discharge.
-Check valve or fitting at discharge side
(OUT port) is clogged.
