1. Precautions for handling
！
Warning
1) Operating environment
•When dangerous fluid or fluid possibly harmful to human is used, take measure to isolate human from
the pump. Should the external leakage of transported fluid come out, the serious damage to human
could be caused.
•When flammable or highly corrosive fluid is transported, keep the fire source away from the pump.
Otherwise, the fire and explosion could be caused.
•Prevent splash of corrosive fluid or other solvents to the external face of the pump.
•If attachment of unknown liquid is found on the external face of the pump, do not touch it without care.
2) External leakage of transported fluid
•When flammable or dangerous fluid is transported, keep the fire source and corrosive material away
from the pump. For this purpose, prepare the vessel for possible leakage and take other measures to
prevent contact with the fire source and corrosive material. Otherwise, the fire and explosion could
be caused.
•During operation of pump, the transported fluid could leak due to life out of the diaphragm. In this
case, take prevention for the leakage to avoid adverse effect to human or facility.
•Do not touch the leakage of fluid without care. If the fluid has high temperature or is chemical, the
contact could result in burn and other injuries.
3) Disassembly
•Do not disassemble the pump.
！
Caution
1) Quality of supplied air
•Mount the filter with filtration of approx. 0.01μ. For the quality of air to be used, refer to Compressed
Air Cleaning Equipments Catalog No. 5∗
∗Typical circuit shown on No.5
Compressor HAW(after cooler) AT(air tank) AFF(main line filter) IDF(refrigerating air
dryer) AM(mist separator) AMD(micro mist separator) PAF
•If the amount of foreign materials generated from air supply (carbon powder etc.) is large, mount
super mist separator etc. to reinforce prevention for attachment of dust. Deposit of foreign materials
could increase resistance and prevent smooth operation.
2) Quality of transported fluid
•If it is known solid materials enter the transported fluid, mount the filter with filtration of 0.2mm at least
on fluid in.
3) Life and replacement
•Suspend operation and replace the diaphragm before it reaches the end of life. If the diaphragm
breaks, the transported fluid leaks inside the pump and exhaust port, and the internal parts of the
pump are damaged and the air blows FLUID OUT port.
Calculation of life of diaphragm (depending on operating conditions)
0.130l (discharge amount per one cycle) X 50 million cycles (referential life cycles)
Referential
life date = Discharge per 1min. (l) X operating time per day (hour) X 60 (min.)
•The pump internal capacity is about 600 ml.
4) Pilot air
•Confirm the supplied pilot air is within specified range from 0.2 to 0.5MPa. The air out of this range
could cause malfunction, stop of operation, damage of internal parts and external leakage.
5) Discharge amount and suction head
•Given discharge rate and suction head are for the condition with fresh water, room temperature,
atmospheric pressure and no piping. Thus, they are varied by physical characteristic of transported
fluid, and in some cases, enough suction head can’t be obtained.
6) Max. Discharge amount
•Given max. discharge rate is for the condition with supplied pressure of 0.5MPa, no suction head,
piping I.D. of 5/8”, piping length of 0.5m.
7) Operating temperature
•The pump is available from 0 to 90 OC, but should be cared not to freeze.(Avoid exposure to heat
cycle)

2. Precaution for installation
！
Caution
1) Mounting
•Only horizontal mounting is available. When the pump is not mounted horizontally with its bottom
faced down, it may cause sucking failure.
•Use four M8 bolts to mount the pump. If the bolts are not tightened firmly, the pump could be exposed
to the vibration and eventually damage.
2) Piping
•Perform flushing enough for piping to avoid intrusion of cutting chips and sealant debris created by
screwing the piping and fitting. If the tape is used for sealing, leave two threads exposed.
3) Material of fitting
•The threaded part is made of resin. Thus, do not tighten the metal fitting to avoid collapse of the
thread.
4) Tightening torque
•Insufficient tightening torque could cause external leakage and excessive one could damage
threaded part and parts. Keep adequate value for tightening.
3. Description and function of individual port
Suction port (FLUID IN) --- To suck transported fluid. Connect suction piping.
Discharge port (FLUID OUT) --- To discharge fluid sucked inside the pump. Connect discharge piping.
Air supply port (AIR SUP) --- Supply compressed air set by regulator etc.
Air exhaust port (AIR EXH) --- Exhaust pilot air.
4. How to use
！
Caution
1) Start and stop
a; Press manual pin.(Only at first operation)
b; Connect air piping to air supply port ”AIR SUP”, and fluid transfer piping to suction port “FLUID IN”
discharge port ”FLUID OUT”.
c; Set pilot air pressure within 0.2 to 0.5MPa by regulator. Pump operates when 3-way valve on air
supply port “AIR SUP” is energized, exhausting noise generated from air exhaust port “AIR EXH”,
and fluid flows from suction port “FLUID IN” to “FLUID OUT”.
At this time, ball valve on discharge side is open. It sucks by itself without priming. To restrict
exhausting noise, mount silencer (AN200-02 option) on air exhaust port “AIR EXH”.
d; Exhaust air supplied from 3-way valve on supply port “AIR SUP” to stop pump.
Thread size Adequate tightening torque (N･m)

2) Adjustment of discharged flow rate
a; Use ball valve connected to discharge side to adjust discharge flow. Do not close valve suddenly, as
it generates surge and remarkably shortens pump life.
b; When discharge flow is under range of specifications, keep minimum flow for process pump by
installing bypass circuit from discharge side to suction side. Discharge flow under minimum flow may
stop pump due to unstable operation.
●Typical circuit
5. Maintenance and check
1) During operation
•During operation of pump, it is necessary to check leakage of fluid and air and operating condition
periodically. If any abnormality or concern is seen, stop the pump immediately and contact local
supplier or SMC.
•When touching the pump for maintenance, put the protective tool such as glove which isn’t affected
by transported fluid to prevent burn.
2) During stop
•If the pump is stopped for a few hours, exhaust the air at supply side.
•If the pump is left unused for extended period, clean inside of the pump to prevent adherence and
sticking of transported fluid over the time which could cause abnormal operation.
3) Check and repair
•Replace the diaphragm before it reaches referential life cycles (specified cycles). If the pump is
continued after the life of diaphragm, the check valves of wetted part as well as the diaphragm are
deteriorated and operating failure could be caused.

7. Discharge capability
1) Flow characteristic
With reference to flow characteristic graph (shown below), operating condition of the pump can be set.
Recommended typical condition A:
Obtain pilot air pressure when discharge rate is 20L/min and discharge pressure is 0.2MPa.
<Assumption; Fresh water (viscosity 1mPa s , specific gravity1.0) is used as transported fluid>
1. Plot the cross point between line with discharge rate 20L/min and line with pressure 0.2MPa.
2. Calculate pressure of transported fluid based on the point. In this example, the point is located
between discharge curves (full line) with 0.3MPa and 0.4MPa and it can be found required air
pressure at this point is approx. 0.37MPa in proportional relation.
！
Caution
●The above flow characteristic graph is for fresh water(viscosity 1mPa s , specific gravity 1.0). Thus, if
the fluid with higher viscosity such as oil is used, convert the fluid to fresh water with reference to
viscosity characteristic graph.
●The discharge rate is affected by characteristic of transported fluid (viscosity, specific gravity,
concentration of slurry) and operating conditions (temperature, pump head, transporting distance)
etc. and should be confirmed before use.
●In the application where the back pressure is applied from discharge port “FLUID OUT”, the result of
(pilot air pressure - back pressure, i.e. pressure difference) is pilot air pressure on the graph. Also, it
should be noted discharge rate decreases compared with normal condition.
●If required output of compressor is calculated from air consumption, consider the output is 0.75 kW
per air consumption of 100L/min (ANR) for reference.

2) Viscosity characteristic
With reference to viscosity characteristic graph (shown below), discharge amount of transported fluid
with higher viscosity can be calculated.
Recommended typical condition B:
Calculate discharge amount of fluid with viscosity 100mPa s in case of discharge rate 9L/min and
discharge pressure 0.2MPa.
1. Find ratio of discharge rate to fresh water for the fluid with viscosity 100mPa s from the graph.
Then, it is found to be 45%.
2. After that, convert it to discharge rate of fresh water.
Since discharge rate 45% of fresh water is equal to 9L/min of the fluid, with the following
calculation;
9L/min ÷ 0.45 = 20L/min
it is found discharge rate 10L/min is necessary for fresh water.
3. Then, refer to flow characteristic graph and calculated air pilot pressure.

Caution
●The viscosity of fluid is affected by operating conditions (temperature, transporting distance etc.)and
fluctuation of ambient temperature.

9. Operating principle
When compressed air is supplied to air supply port within 0.2 to 0.5MPa, internal directional control
valve operates and diaphragm starts reciprocation.
Air is supplied in actuating chamber shown in Fig.1, fluid in pump chamber is flowed out. Meanwhile,
pump chamber B sucks fluid.
When pilot valve is pushed out at stroke end, built-in directional control valve is shifted, and starts
reverse operation (Fig.2). This repeated operation realizes continuous suction and discharge.
