Make sure there is no one around the pump when connecting the power cable. The
power supply switch is not provided on the pump. Connecting the power cable and
supply air to the pump starts pump operation.
•Do not remodel pump
Never try to remodel the pump. Remodeling may be a cause of serious accident or
damage. Iwaki takes no responsibility for accidents or damages that may result due
to any remodeling without first obtaining permission from Iwaki.
•For specified application only
The use of a pump in any application other than those clearly specified may result in
injury or damage to the pump. Use the pump strictly in accordance with the pump
specifications and application range.
•Do not drain
Never discharge hazardous liquid, including but not limited to chemical liquid, over
the ground or floor in the plant directly.
Abide by local regulations when disposing of hazardous substances.
•Do not touch
Touching the pump or piping which is extremely hot due to the circulation of a hot
liquid may cause severe burns. Arrange adequate hand-protective measures when
feeding a liquid at temperatures higher than 50 °C.
CAUTION
•Do not exceed the specified voltage
Do not supply power voltage in excess of the level specified. Otherwise, a fire or
electric shock may resulted.
•Wear protectors
Never fail to wear protective gear (protective goggles, cap, mask, acid-resistant
gloves) when disassembling, assembling, or maintaining the pump. In addition,
clean the pump carefully with pure water before working on the pump.
•Qualified operator only
The pump must be operated only by operator(s) who have been trained in the safe
operation of the pump.
Safety Section

CAUTION
•Lifting pump
If a lifting rope or chain breaks or is cut when lifting the pump, a fatal or serious
injury to person may result from the accident. Select a lifting rope or chain which is
strong enough for the load of the pump. Furthermore, no person should be allowed
to get under the pump while it is being lifted.
•Power OFF
Make sure no one turns on the power switch while work is being done on the pump.
Be sure to turn off the power switch before you start any maintenance/repair work
concerning the pump. If the working site is noisy or under conditions of low visibility,
you should display a notice which clearly states "POWER Off(Maintenance)," near
the power switch in order to inform other personnel about the situation. Power ON
executed by any other person than the operator/service personnel may result in a
serious accident. The operator must take special precautions to avoid accidents.
•Storage limit
Do not store the pump in places where an explosive atmosphere is located, dust is
generated, or corrosive gas (such as chlorine gas) is present. Otherwise, a fire may
be caused or the health of personnel may be jeopardized.
•Ventilate site
When handling a toxic liquid or odorant, ventilate the working site well. In addition,
wear protective gear (protective mask, goggles, gloves, etc.).
•Disposal of used pump
Disposal of used or damaged pumps must be done in accordance with local laws
and regulations. (Consult a licensed industrial waste products disposing company.)
•Send-back to Iwaki
When sending the pump back to Iwaki, drain the liquid out of the pump and clean
thoroughly with water to prevent any accidents during transportation.
•Pump stroke speed
Do not run the pump at a stroke speed higher than the max. stroke speed which is
shown on the item 4. Specifications on page 8. A stroke speed higher than Max.
stroke speed shortens the life of the bellows.

CAUTION
•Supply air pressure
Supply air pressure must be maintained within specified supply air pressure range.
Otherwise, the bellows may be deformed.
•Liquid temperature range
Pumped liquid temperature should be 5-180 deg.C.
•Prohibited liquids
Do not operate the pump with the following liquids.
· Liquid easily crystallized
· Liquid containing slurry
· Solvent naphtha
•Liquids to be handled with care
Stripper, solvent-type liquid, hydrazine or fuming sulfuric acid should be handled
carefully.
•Air exhaust port
Do not narrow the air exhaust port (for example by reducing the tube diameter).
Otherwise the bellows may be deformed due to the residual pressure.
•During pump operation
· Make sure to open both the suction and discharge-side valves fully. In addition,
confirm that the piping is fully supplied with liquid.

Safety Section
CAUTION
•Stopping pump operation
· When stopping pump operation, release the pressure on the discharge side first.
Otherwise, the bellows may be deformed due to the residual pressure on the
pump discharge side.
· If a valve is provided on the discharge side, do not close the valve upon stopping
the pump. The resulting impactive pressure may deform the bellows or connect-
ing plate.
•Pump at halt
Do not supply air to both the right and left air-supply ports at the same time, to pre-
vent the bellows from becoming deformed.
•Note for electrode
There is a case which electrode could not detect leakages. This comes from oper-
ating condition (supply air pressure etc) and size of crakes on the bellows. please
contact IWAKI for detail.
•Static electricity
When low electric conductivity liquids such as ultra-pure water and fluor inactive liq-
uid (e.g. FluorinertTM) are handled, the static electricity may be generated in the
pump, which may cause static discharge and pump break down. Take countermea-
sures to avoid and remove the static electricity.

1. Unpacking and Inspection
Iwaki's air-driven bellows pumps are made entirely of
fluororesin and designed for semiconductor manufac-
turing processes.
The pump unit consists of two air chambers and a pair
of bellows. These bellows move reciprocally in the air
chambers for suction and discharge, by which the liquid
is pumped continuously.
[1] Liquid is sucked into the pump head through the
suction port by the expansion (suction motion) of
the bellows.
[2] The liquid is then forced out of the pump head
through the discharge port by the compression(dis-
charge motion) of the bellows.
2. Operation Principle
Wiring depends on type of controller.

This “Installation Section“ must be thoroughly understood by the user before
actually installing the pump. Do not start your installation work unless you
confirm your understanding of the entire set of descriptions in this section.

- 15 -
1. Before Use
For reliable pump performance to suit your application purposes, full safety measures should be taken for
the pump unit and the entire system. The following information, including the points to be observed in the
handling of the pump, deals with the measures to ensure the safe operation of the system. Please read
the description carefully.
To operate this pump, a 5-port solenoid valve and a controller (AC-1 type, FD type, SC type or FDC-1
type) are required.
In addition, to enhance system safely, a quick exhaust valve must be installed.
No. Points to be Observed Description
1™Pump stroke speed:
Do not run pump exceeding the max.
stroke speed which is shown on the
item 4. Specifications on page 8.
¡If many air bubbles are sucked through pump suction port, pump
is put into state of air locked operation and stroke rate will rise to
abnormal levels. Safety measure should be taken so that pump
does not run at speeds above max. stroke speed. With FD, SC or
FDC-1 controller, the upper limit of stroke speed can be set.
2™Supply air pressure must be
maintained within specified
pressure range.
¡In view of pressure resistance of filter at medium temperature,
provide air under as low pressure as possible, for protection of
bellows & to ensure safety.
¡Any fluctuation in pressure of supplied air causes change in
discharge. Attach reducing valve to stabilize pressure.
4™Prohibited liquids
Caution
Following liquids must not be used.
• Liquids that are easily crystallized
• Liquids containing slurry
• Low conductivity carbon hydrate
liquid
¡Service life of valve & bellows is shortened with use of liquid that
is easily crystallized or contains slurry. Use of such liquids is not
recommended.
¡If solvent naphtha is used, electrostatic destruction may be
generated between fluororesin & liquid, finally producing
pinholes.
3™Liquid temp. range ¡Temp. of pumped liquid must be within the range of 5-180 deg.C.
Pump type Liquid temperature range Supply air pressure range
FS-15·30·60
5-50 deg.C 0.147-0.490 (MPa)
51-100 deg.C 0.147-0.294 (MPa)
101-180 deg.C 0.147-0.196 (MPa)

- 16 -
No. Points to be Observed Description
5™Liquids to be handled with care
· Stripper
· Hydrazine
· Fuming sulfuric acid
· Solvent type liquids
¡Some types of strippers may cause cracks in bellows or piping
(PFA) at an early stage. (Contact Iwaki for a different warranty
period applied for such liquids.)
¡Explosion-proof specifications are required to use solvent type
liquid. (Contact Iwaki for details.)
6™When stopping pump operation, do
not close discharge valve before
releasing all pressure from bellows.
Caution
Stopping pump without releasing pressure on pump discharge
side may result in deformed bellows due to force of pressure
remaining on pump discharge side.
9™Do not supply air to both right & left
air supply ports when pump opera-
tion is suspended.
Caution
¡If air is supplied simultaneously to two air chambers on right & left
sides while pump operation is suspended, bellows are pressurized
& will finally deform.
¡Be especially careful when using double solenoid electromagnetic
valve, because some types of valve cause simultaneous
pressurization of two air chambers between valve stops.
10 ™Do not close the secondary-side air
valve upon stopping the pump. Caution
¡If the secondary-side air valve on the liquid line is closed upon
stopping the pump, the resulting residual pressure in the bellows
may cause a deformation of the bellows or connecting plate.
¡Note that the secondary-side air valve is kept open except for the
purpose of drainage.
7™Do not suspend pump operation for
a prolonged period without first
removing the liquid from the pump
chamber.
Caution
Suspending pump operation for a prolonged period without
removing liquid inside the pump chamber may cause corrosion of
the electrode or other parts due to permeation of the liquid’s gas
content.
(Example: Pump operated once a day for a minimum period of 10
minutes.)
In sush a case, contact Iwaki for special instructions.
8™Do not narrow air exhaust port. (Do
not use tubing of smaller diameter
than specified.)
Caution
If exhaust port piping of 5-port solenoid valve is extended longer
to position other than specification, & air exhaust port is narrowed,
bellows may be deformed by force of supply air resulting from
imbalance between discharge side pressure & supply air
pressure.

■Other precautions to be taken
[1] Surface temperature of pump
Warning
Touching the pump or piping whose surface temperature is extremely high due to the circulation of a hot liquid is very
dangerous. Always arrange adequate hand-protective measures when engaged in feeding a hot liquid into the
pump. The max. pump surface temperature is shown in the table.
[2] Noise from pump
Noises are generated from air exhaust or the like during pump operation. Apply sound damping measures as necessary. The
Level of sound generated by pump is shown in the table.

WARNING
Make sure no one turns on the power switch while work is being done on the pump. Be sure to turn off the
power switch before you start any maintenance/repair work concerning the pump. If the working site is
noisy or under conditions of low visibility, you should display a notice which clearly states “POWER
OFF(MAINTENANCE),” near the power switch in order to inform other personnel about the situation.
Power ON executed by any other person than the operator/service personnel may result in a serious
accident. The operator must take special precautions to avoid accidents.
Only the operators/service staff who are adequately trained in safe handling procedures should be in
charge of the related electric arrangement and control of the power source. Iwaki takes no responsibility
for injury to person or damage to assets which results from a failure to observe this instruction. Consult
Iwaki, an Iwaki branch office, or an Iwaki distributor as necessary.
When you feel or notice any danger or abnormal condition during installation and other set-up work, stop the work and
go back to the very first step.
2.1 Installation
[1] Pump installation position
¡Flooded suction system
Set the pump as close to the liquid supply tank as
possible.
Caution
Employ a flooded suction system for feeding a liquid
at higher temperatures than room temperature or for
a liquid circulation system.
¡Suction lift system
Set the suction side piping in accordance with the
self-priming capacity and as close to the liquid sup-
ply tank as possible.
* Self-priming capacity :
FS-15 : 1m
FS-30 : 2m
FS-60 : 2m
Caution
The self-priming capacity above is based on a pump operation at the max. stroke speed using pure water at room
temperature. The suction height differs with the liquid’s characteristics, temperature, and suction pipe length. For
detailed information, contact Iwaki.
[2] Installation foundation
Select a flat and rigid foundation (such as a chassis) for installation, to avoid twisting motion or vibration.
[3] Direction of pump
Direct the discharge port upward and the suction port horizontally. Use anchor bolts to fasten the pump firmly in
position.
[4] Bolt tightening
Tighten the bolts on the housing upon installation by applying the following fastening torque.
Fastening torque for FS-15HT1: 9.8N•m FS-15HT2: 4.9N•m
FS-30HT1: 15.7N•m FS-30HT2: 5.9N•m
FS-60HT1: 21.6N•m FS-60HT2: 6.9N•m
