Warning
1. Do not use this product in applications which may
adversely affect human life (e.g. medical equipment
connected to the human body for drip infusion).
2. Confi rm the specifi cations.
Give careful consideration to the operating conditions such as
the application, fluid and environment, and use within the
operating ranges specifi ed in this catalog.
3. Do not apply pressure to the pump. If the pump op-
erates with pressure applied, the repeatability may
decrease or liquid may leak to the OUT side when
the pump is off.
∗
Refer to page 7 “Piping, Caution 1 .” for the installation
position of the pump.
4. For stable dispensing, please use the product under
stable operating conditions (suction height, ambient
temperature, fluid temperature). If air bubbles are
present in the fluid and the piping material is soft, it
may influence on the repeatability of the dispense
volume. Install the pump vertically facing downward
so that air bubbles in the pump are removed easily.
It is recommended to degasify the fluid and use
hard material for piping.
When the piping diameter of the fluid outlet is large,
repeatability may be influenced by surface tension,
so it is recommended to use proper piping diameter
with the installation of a nozzle.
5. Repeatability
Measure the amount of clear water which is dispensed 10 times
continuously and convert it to one shot of dispensed volume.
Repeat this measurement 1 0 times, and indicate the difference
(%) between the average value of 1 0 sets of data (converted
value of one shot) and the maximum and minimum values.
These values are calculated based on SMC measurement
conditions, so the repeatability accuracy is not guaranteed.

Tank liquid
level must be lower than the pump and the OUT side tube
end must be higher than the tank liquid level. Remove any
air bubbles in the piping and pump chamber.
Ambient/Fluid temperatures:
±
2
°C, IN/OUT side piping
pressure:
±
0.1 kPa or less, Applied voltage:
±
0.01 V
6. Fluid
Be sure to confi rm the compatibility between the component
material and the fl uid. Since the compatibility of the fl uid used
may vary depending on its type, additives, concentration,
temperature, etc., give suffi cient consideration when selecting
the material.
If the fl uid contains foreign matter, it may be caught in the seat
or cause wear on the inside of the pump, causing problems.
Install an appropriate fi lter (strainer) before the pump. As a guide,
the appropriate fi ltration is approximately 50
μ
m.
When transferring a coagulable liquid, take measures to prevent
it from coagulating in the pump.
This product is not designed to be explosion proof, so it is not
suitable for fl ammable fl uids.
7. Dispense volume will vary depending on the fluid
and piping conditions.
After mounting is complete, perform appropriate functional
inspections.
8. Maintenance space
The installation should allow suffi cient space for maintenance
activities.
9. Ambient environment
Use within the allowable ambient temperature range.
Be sure that the liquid or corrosive gas does not touch the
external surface of the product.
Specifi cally, do not expose the solenoid to fl uid. This may cause
short circuit. When touching the wet solenoid, an electric shock
may occur.
10. Countermeasures against static electricity
Take measures to prevent static electricity since some fl uids
can cause static electricity.
11. Energizing for extended periods of time
If the pump is continuously energised for long periods of time,
temperature rise due to heat generation of the coil may result
in reduced performance and shorter service life or adversely
affect the peripheral device. Therefore, if the pump is energised
for long periods, take measures to cool the pump by mounting
a fan to keep the surface temperature at 50
°C or less.
When the pump is mounted into a control panel, take measures
to cool the pump and keep the operating temperature within
the specifi ed range.
12. If the product has not been used for long periods
of time, perform a trial run before use. If the prod-
uct is to remain inactive for long periods of time,
remove the fl uid from the pump.
13. Do not touch the pump directly with hands. The coil
can be hot depending on the ambient temperature
or energising time. Install a protective cover over
the valve if it can be touched directly with hands.
14. Leakage voltage
Voltages caused by leakage current may lead to pump mal-
function.
Leakage voltage: 2 % or less of the rated voltage
Mounting
1. If equipment does not operate properly, stop operation.
After mounting is completed, confirm that it has been done
correctly by performing a suitable function test.
2. For stable dispensing, mount the coil vertically fac-
ing downward so that bubbles in the pump are re-
moved easily.
After releasing air bubbles, mounting orientation is not specifi ed.
3. Do not use this product in a location where it will be
subject to vibration or impact. The dispense volume
may become unstable in the presence of vibration
at the pump or piping.
4. Do not apply external force to the coil section.
5. Install and operate the product only after reading
the operation manual carefully and understanding
its contents.
Be sure to read this before handling the products. Refer to the back cover for safety
instructions and the “Operation Manual” for handling the products. Please download
the Operation Manual via our website, https://www.smc.eu
