1 INTRODUCTION
Thank you for selecting an Iwaki America FA-2E Air Driven Bellows Pump. These pumps are designed
exclusively for pumping semiconductor grade, high purity liquids. To ensure safety and maximum service
life of the pump, please read this instruction manual thoroughly prior to installation and operation.
1. This instruction manual details the proper installation, operation and safety measures necessary to
2. Always employ full safety measures and precautions when installing or servicing this type of pump
3. To operate the pump, a controller system with adequate control and safety features is necessary. The
4. Please ensure that the end-user receives a copy of this instruction manual for reference.
CAUTION!
ensure the safe and efficient use of this pump. Failure to adhere to the described handling, installation
and operating procedures may lead to malfunction or damage to the pump.
based on the liquid being handled. Common applications are hazardous strong acids. Follow all safety
procedures recommended by the chemical manufacturer.
pump always requires the use of a 4-way solenoid valve. Please read the respective instruction manuals
carefully for the proper installation and operating guidelines.
2 UNPACKING AND INSPECTION
Open the package and check that the product conforms to your order. Also check each of the following
points. For any problem or inconsistency, contact Iwaki America at once.
1. Check that the model number indicated on the nameplate conforms to the specifications of your order.
2. Check that the pump body and parts have not been accidentally damaged or that any fasteners have not
been loosened in transit.
Figure 1
Iwaki America F Series Air Driven Bellows Pumps consist of a high purity virgin fluoroplastic pump head
assembly with dual bellows and internal valving. A bellows is affixed on each side of the pump head
assembly which houses the suction and discharge valves. A connecting rod and shaft system are mounted
to the bellows and structural air chambers which seal against the pump head assembly. The bellows move
reciprocally in the air chambers as a result of alternating pressurization of the air chambers, by which liquid
is pumped continuously. Position of each bellows is monitored by proximity sensors mounted in the air
chambers. Signals from the proximity sensors are used by the controller system to govern the 4-way
solenoid valve and subsequent pressurization of the pump air chambers.

2.1 Operation Sequence
Figure 2
Refer to Figure 2. When pressurized air is supplied to chamber 'a' of the pump, bellows 'A' is
compressed and fluid is discharged from the bellows through the pump head discharge (outlet) port.
Simultaneously, bellows 'B' is extended and fluid is drawn into the bellows through the pump head
suction (inlet) port. Air is being exhausted from pump chamber 'b' during this process. When bellows
'B' is fully extended, proximity sensor 'B' is activated to signal the completion of this stroke to the
controller system.
The controller system receives the input signal from proximity sensor 'B' and changes the output
signal to the 4-way solenoid valve to switch it from the a0 position to b0 position.
Refer to Figure 3. Once the 4-way solenoid valve is in the b0 position, pressurized air is supplied to
chamber 'b' of the pump and the process outlined above is reversed. Fluid is discharged from bellows
'B' while bellows 'A' is in its suction stroke and air is exhausted from chamber 'a.' Upon completion o
this pump stroke, proximity sensor 'A' is activated and the controller signals the valve to switch from
the b0 position to a0.
With a constant air supply, this sequence is repeated continuously and the pump achieves a constant
flowrate based on installation and operating conditions.
