Precautions
1. Caution on design
Warning
1. Confirm the specifications.
- Give careful consideration to operating conditions such as the application, fluid and environment,
and use the product within the operating ranges specified in this catalog.
- The product is provided for physical, chemical and industrial equipment.
2. Fluids
- When ignitable fluid is used, use a product with metal wetted parts (aluminum, stainless steel).
Always take countermeasures against static electricity.
- For the compatibility between the materials composing the product and the fluids, check the
compatibility check list. Since the compatibility of the fluid used may vary depending on its type,
additives, concentration, temperature, etc., give sufficient consideration when selecting the
material.
- For fluids other than those listed on the check list, please consult us.Also, use them within the
range of the operating fluid temperatures.
- If foreign matters are mixed in the fluid, these may cause abrasion of the inside of the pump
resulting in a problem. Use an appropriate filter (strainer) to remove them. In general, 80 to 100
mesh (150 to 180 μm) filters are recommended.
- When transferring a coagulable liquid, take measures to prevent it from coagulating in the pump.
- Please contact SMC sales office for the use of slurry.
- Take countermeasures to prevent the operating fluid from getting onto the body of the process
pump.
3. Water hammer
If a valve is operated abruptly etc., a high pressure may be applied due to water hammer. Take
measures to prevent pressures higher than specified from being applied.
<Examples of measures>
- Use a water hammer resistant valve to reduce the valve closing speed.
- Use an elastic piping material such as rubber hose or an accumulator to absorb the impact
pressure.
4. Liquid seals
To ensure that fluid does not become sealed inside the process pump, when
stopping the pump, relieve the discharge pressure inside it. As shown in the
figure at right, make a circuit which has a relief valve installed on the
system.
5. Fluid pressure supplied to the process pump
Feeding the fluid from the suction side into the pump under pressure, or
Drawing it using a negative pressure, will reduce the life of the pump.
6. Ensure space for maintenance.
Secure the space required for maintenance and inspection. Take into consideration also leakage
from the product. When transferring a flammable liquid or a liquid that may affect the human body
or environment, take measures including fire ban and keeping the area off limits.
7. When the diaphragm is broken, supply air will be mixed with the fluid or the fluid will enter
the air switching valve. This may affect the product performance, or the chemical
resistance of the components may not be suitable. Countermeasures need to be taken by
the customer.
8. Use a design which prevents reverse pressure and reverse flow.
If reverse pressure or reverse flow occurs on the discharge side of the process pump, the
equipment is liable to become damaged or malfunction. Take safety measures in designing the
circuit.
9. Measures against static electricity
Take measures against static electricity as static electricity may occur depending on the fluid.
Particularly, when circulating flammable fluid through the pump, be sure to take measures to
prevent the occurrence of static electricity.
10. The pump cannot transfer gas. Do not allow it to idle for a long time.
If the pump is operated for a long time without any fluid inside or in a gas-fluid mixed state, the
diaphragm may be damaged or the life may be shortened. Do not continue idling except for
priming the pump.

6
11. Condensation and freezing of the pilot port
The location around the switching valve and the air exhaust port can cool down quickly due to
expansion of the supply air, and this may cause condensation on the piping and the condensation
may freeze during operation in winter. Take measures to ensure that water droplets from
condensation are not splashed onto any electric parts or equipment.
Caution
1. Suspension of the pump operation
When operation is stopped exhaust the residual pressure of the air supply port using the 3-port
solenoid valve. Stopping the process pump while air is supplied, load is applied to the internal
parts and the life will be shortened. If the process pump is stopped consuming the residual
pressure, the operation of the switching part of the pilot air in the process pump becomes
unstable and may not be restarted. When the operation cannot be restarted, press the reset
button.
2. Use the constant pilot air pressure.
The process pump may malfunction and stop when the pilot air pressure fluctuation exceeds 50
kPa.
3. Reverse flow
The check valve inside the process pump does not completely stop reverse flow (the flow from
the discharge side to the suction side). For this reason, fluid may sometimes flow from the
discharge side to the suction side when the pump is stationary, etc). As a countermeasure, install
a 2-way valve or a check valve. However, please note that when a check valve is installed, if the
cracking pressure is high, defective suction may occur. (As a guide, the cracking pressure should
be 0.02 MPa or less.)
2. Mounting
Caution
1. Read the operation manual before mounting the product.
Read the operation manual carefully and understand the contents before mounting the product.
The manual should also be kept where it can be referred to whenever necessary.
2. Confirm the mounting orientation of the product.
Face the foot downward. Fix the pump and the mounting foot with the included screws (tightening
torque: 2.5 N･m). Also, secure all specified mounting positions when using the product.
If the propagation of the vibration of the pump is not acceptable, insert vibro-isolating rubber when
mounting.
3. Piping
Caution
1. Flush the piping.
Flush and clean the piping before connecting the product.Any dirt or scale and the like left in the
piping may cause malfunction or failure.
2. Use fittings with resin threads when connecting piping to the product with resin threads at
the ports.
Using fittings with metal threads may cause damage to the ports.
3. Tighten screws with proper tightening torque.
When screwing fittings into the product, tighten them with proper tightening torque as shown
below. Looseness can cause problems such as fluid and air leaks, while over tightening can
cause damage to threads and parts, etc.

4. Air Supply
Warning
1. Use clean air.
Do not use compressed air that includes chemicals, synthetic oils containing organic solvents,
salinities or corrosive gases, etc., as it can cause damage or malfunction.
2. Pay attention to avoid freezing when operating the product in low temperatures.
The equipment operates while expanding the compressed air. During this time, the temperature
inside the product decreases due to adiabatic expansion. If the ambient temperature is low, using
compressed air containing a lot of moisture may cause freezing because heat cannot be gained
from the surroundings. In this case, take freeze prevention measures by using a membrane air
dryer (such as series IDG).
Caution
1. Quality of operating air
- Be sure to use only air filtrated by a micro mist separator (such as series AMD). Use of a super
mist separator (such as series AME) is recommended to extend maintenance intervals.
-When dew forming or freezing occur in the process pump, use the membrane air dryer (IDG)
and decrease the dew point of supply air.
- If a pump is operated by N2 gas, etc., the deterioration of the gaskets inside the switching valve
will be accelerated and may result in substantially shortening the life span of the product.
2. Compressed air with low dew point
If compressed air with an atmospheric dew point below -40oC is used, the lubrication properties
inside the equipment can deteriorate prematurely, affecting the life of the equipment.
When compressed air with an atmospheric dew point below -40oC is used for the operating
environment or as supply air, testing under user’s operating conditions is recommended.
5. Operating environment
Warning
1. Do not use in the following environments, as this can cause failure.
1) Locations with an atmosphere of corrosive gases, organic solvents or chemical solutions, and
where there may be contact with the same.
2) Locations where there is contact with sea spray, water or steam.
3) Locations where ultraviolet deterioration or overheating of resin may occur due to direct
sunlight.
4) Locations near heat sources with poor ventilation (heat sources should be shielded by heat
insulating material).
5) Locations with impact or vibration.
6) Locations with excessive moisture and dust.
2. The product cannot be used under water.
Do not use the product immersing it in water (liquid). Otherwise, liquid will enter the openings
inside the product, resulting in malfunction.
3. Depending on the fluid used, a flammable atmosphere may occur. Take measures
such as ventilation.
6. Maintenance
Warning
1. Perform maintenance after consulting the operation manual.
Obtain the operation manual for the equipment from SMC or our distributor and have sufficient
knowledge of the equipment before performing maintenance. Incorrect handling may cause
damage or malfunction of the equipment or system.
2. Perform maintenance work after confirming the safety of the system.
Turn off the compressed air and power supply and exhaust any remaining compressed air in the
system before removing the equipment and the compressed air supply/exhaust unit. Discharge
the residual liquid or sufficiently displace it as necessary. Also, when reinstalling the equipment or
restarting it after replacement, confirm the safety of the product before checking that it operates
normally.

8
3. Use appropriate protective equipment.
When touching the process pump for maintenance, wear protective equipment such as gloves
which are compatible with the fluid used. There is a risk of chemical burns.
4. Do not disassemble the product, as disassembly will invalidate the product's
warranty.
When disassembly is necessary, please consult with SMC or our distributor.
5. Drain discharge
Operating the system with drain accumulated in the equipment or piping may cause malfunction
of the equipment, splash over into the downstream side, or unexpected accident. Periodically
discharge drain from components including the air filter.
6. Caution when transferring a high-temperature fluid
The product itself will become hot due to the high-temperature fluid. Since touching the product
directly may cause burns, allow sufficient time for the product to cool down when transferring a
high-temperature fluid. The measurement of the product temperature is recommended to confirm
the safety of the system before performing work.
7. The bolts in this product may become loose over time due to creep of the PP housing.
Retighten the bolts before operation to prevent fluid or air leakage (refer to the
maintenance manual for the required tightening torque).
Caution
1. Caution when transferring a highly penetrating liquid
When transferring a liquid that is highly penetrating through fluoropolymer, components of the
transfer liquid may enter the openings inside the equipment.Also, they may become attached to
the external surface of the equipment. In this case, take the same measures as handling the
transfer liquid.
2. Service life of diaphragm and maintenance of consumable items
- If the operating cycle of the process pump exceeds the service life of diaphragm, the diaphragm
may be damaged due to deterioration. If it is damaged, the fluid will leak from the pilot air
exhaust port and the air will blow out into the liquid circuit. Consider the pump operation
(breathing, decline of discharge pressure, etc.) and the reference service life of diaphragm, and
replace with new process pump or conduct necessary maintenance as early as possible.
- Items such as check valves, switching valves, pilot valves and manual caps may experience
malfunction earlier than the diaphragm depending on the operating conditions. Please replace
with new process pump or conduct periodic maintenance.
- When conducting maintenance, obtain the necessary parts indicated in the maintenance parts
list (Refer to P.15), and perform work according to the maintenance and operation manuals.

Caution
1. The pump can be used without lubrication.
2. If lubricating the pump, continue lubrication.
If lubricating a pump, use turbine oil Class 1 (with no additives) ISO VG32, and be sure to
continue lubricating the pump.
8. Caution on Handling
Warning
1. Test before using with the actual equipment.
Test the pump before using it with the actual equipment. Even if there is no problem in a
short-term test, the liquid may penetrate through the fluoropolymer diaphragm causing
malfunction in the pump air circuit.
2. Storage
In the case of long-term storage after use, first thoroughly remove the liquid, and clean and dry
the inside to prevent deterioration of the pump materials.
3. After a long period of non-use, perform a trial run prior to operation.
4. Ensure that the bolts are not loose before operating the process pump. Retighten if
necessary.
5. Discharge volume adjustment
Always connect the discharge volume adjustment valve to the FLUID OUT of the process pump.
Adjust the volume by operating the valve.
6. When the discharge volume is large (flow speed is high), depending on the fluid type
and operating conditions, there will be cavitation, leading to a poor operation or
malfunction. Decrease supply air pressure or decrease the discharge volume with a
throttle so that cavitation is not generated.
7. Operating environment
When dangerous fluid is used, take measures to isolate humans from the pump. External leakage
of transferred liquid could cause serious injury.
8. External leakgage of transferred liquid
There are some cases where the operating fluid will leak outside the pump, for example when
thediaphragm reaches the end of its life. Depending on the operating fluid, take measures
against external leakage, including installing a drain pan, to avoid adverse effects on humans and
equipment.
9. Caution for piping of the tube
Support the piping according to JIS B 8370 when piping the tube. Ensure that tensile force is not
applied to the tube.。

Flow Rate Characteristics

Selection from Flow Rate Characteristic Graph
Required specifications example:
Find the pilot air pressure and air consumption of pilot air for a discharge rate of 27 L/min and a
discharge pressure of 0.25 MPa. <The transfer fluid is fresh water (viscosity 1 mPa•s, specific
gravity 1.0).
If the total lifting height is required instead of the discharge pressure, a discharge pressure of 0.1
MPa corresponds to a total lift of 10 m.
Selection procedures:
1. First mark the intersection point for a discharge rate of 27 L/min and a discharge pressure of 0.25
MPa.
2. Find the pilot air pressure for the marked point. In this case, the point is between the discharge
curves (solid lines) for SUP = 0.4 MPa and SUP = 0.5 MPa, and based on the proportional
relationship to these lines, the pilot air pressure for this point is approximately 0.46 MPa.
3. Next find the air consumption rate. Since the marked point is below the curve (long dashed short
dashed line) for 200 L/min (ANR), the maximum rate will be about 200 L/min (ANR).
Caution
1. These flow rate characteristics are for fresh water (viscosity 1 mPa·s, specific gravity 1.0).
2. The discharge rate differs greatly depending on properties (viscosity, specific gravity) of the fluid
being transferred and operating conditions (lifting range, transfer distance), etc.
3. Use 0.75 kW per 100 L/min of air consumption as a guide for the relationship of the air
consumption to the compressor.

Viscosity Characteristics
Selection from Viscosity Characteristic Graph
Required specifications example:
Find the pilot air pressure and pilot air consumption for a discharge rate of 12 L/min, and a viscosity
of 100 mPa·s.
Selection procedures:
1. First find the ratio of the discharge rate for fresh water when viscosity is 100 mPa·s from the
graph above. It is determined to be 68%.
2. Next, in the required specification example, the viscosity is 100 mPa·s and the discharge rate is
12 L/min. Since this is equivalent to 68% of the discharge rate for fresh water, 12 L/min ÷ 0.68
=17.6 L/min, indicating that a discharge rate of 17.6 L/min is required for fresh water.
3. Finally, find the pilot air pressure and pilot air consumption based on selection from the flow
characteristic graphs.
Caution
Viscosities up to 5000 mPa·s can be used.

Working Principle
1. When air is supplied, it passes through the switching valve and enters drive chamber B.
2. Diaphragm B moves to the right, and at the same time diaphragm A also moves to the right
pushing pilot valve A.
3. When pilot valve A is pushed, air acts upon the switching valve, drive chamber A switches to a
supply state, and the air which was in drive chamber B is exhausted to the outside.
4. When air enters drive chamberA, diaphragm B moves to the left pushing pilot valve B.
5. When pilot valve B is pushed, the air which was acting upon the switching valve is exhausted,
and drive chamber B once again switches to a supply state. A continuous reciprocal motion is
generated by this repetition.
1. When air enters drive chamber B, the fluid in pump chamber B is forced out, and at the same time
fluid is sucked into pump chamberA.
2. When the diaphragm moves in the opposite direction, the fluid in pump chamber A is forced out,
and fluid is sucked into pump chamber B.
3. Continuous suction and discharge is performed by the reciprocal motion of the diaphragm.
Maintenance Parts
- It is not recommended to disassemble the process pump. However, if this is necessary,
be sure to follow the instructions in the maintenance procedure.
- When carrying out this work, wear appropriate protective equipment.

Piping and Operation
Caution
Mounting posture of the pump is set with the mounting foot facing downward.Air to be supplied to
the air supply port <AIR SUP> should be cleaned and filtered throughAF filter, etc. Air with foreign
matter or drainage etc. will have negative effects on the built-in directional control valve and will lead
to malfunction. When air needs additional purification, use a filter (AF series), and a mist separator
(AM series) together. Maintain the proper tightening torque for fittings and mounting bolts, etc.
Looseness can cause problems such as fluid and air leaks, while over tightening can cause damage
to threads and parts, etc.
Starting and Stopping Refer to circuit example (1)
1. Connect air piping to the air supply port <AIR SUP> and connect piping for the fluid to be
transfered to the suction port <FLUID IN> and the discharge port <FLUID OUT>.
2. Using a regulator, set the pilot air pressure within the range of 0.2 to 0.5 MPa. Then, the pump
operates when power is applied to the 3 port solenoid valve of the air supply port <AIR SUP>, the
sound of exhaust begins from the air exhaust port <AIR EXH> and fluid flows from the suction
port <FLUID IN> to the discharge port <FLUID OUT>.
At this time, the throttle on the discharge side is in an open state. The pump performs suction with
its own power even without priming. (Dry state suction lifting range: up to 2 m) To restrict exhaust
noise, attach a silencer (AN20-02: option) to the air exhaust port <AIR EXH>.
3. To stop the pump, exhaust the air pressure being supplied to the pump by the 3 port solenoid
valve of the air supply port <AIR SUP>. The pump stops even when the throttle on the discharge
side is closed. But the pressure supply to the pump should be exhausted quickly.
Discharge Flow Rate Adjustment
1. To adjust the flow rate from the discharge port <FLUID OUT>, use the throttle connected to the
discharge side. Refer to circuit example (1). Note that this product cannot be used as a fixed
quantity liquid dispense pump.
2. When operating with a discharge flow rate below the specification range, provide a by-pass circuit
from the discharge side to the suction side to ensure the minimum flow rate inside the process
pump. With a discharge flow rate below the minimum flow rate, the process pump may stop due
to unstable operation. Refer to circuit example (2). (Minimum flow rates: 5 L/min)
<Reset Button>
When the pump stops during operation, press the reset button. When the reset button needs to
be pressed frequently, replacement of the product or maintenance of the switching valve is
necessary.
