  • Page 3: Introduction

    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.

  • Page 4: Unpacking And Inspection

    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.

  • Page 5: Operation Sequence

    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.

  • Page 9: Handling Precautions

    4 HANDLING PRECAUTIONS The following information deals with measures to ensure safe operation of the pump system. Please read the precautions carefully. To operate this pump, a 4-way solenoid valve and a controller (Iwaki America supplied model or host PLC) are required.

  • Page 10: Pump Handling Precautions

    Pump Handling Precautions • Do not stop pump without opening discharge first: When stopping pump operation, first release pressure in the discharge line & then shut off supply air pressure. Residual pressure in the liquid discharge piping may result in deformation of the bellows due to the force of hydraulic pressure.

  • Page 11: System Safety Precautions

    • Prohibited liquids: The following liquids must not be used: - Liquids that are easily crystallized - Liquids containing slurry - Solvent based fluids Service life of the valve and bellows is shortened by liquids that are easily crystallized or contain slurry. Some solvents may cause premature failure due to incompatability with liquid end materials.

  • Page 12: Liquid Circulation System Design Recommendations

    Liquid Circulation System Design Recommendations In typical semiconductor wet process liquids, a catalyst such as H O, O or H is added to the process liquid. The subsequent reaction generates heat and produces extreme gassing of the liquid. Measures should be taken to reduce the amount of gas laden liquid which can enter the pump chambers. Excessive gas can cause an air lock condition for the pump which may increase the pump stroke rate to excessive levels.

    3. Another technique is to install an air detection sensor in the suction port area, so that the auto valve is automatically opened by a signal sent out from the sensor and the air elimination operation is initiated. 5 INSTALLATION, PIPING & WIRING SUCTION LIFT SYSTEM...

  • Page 14: Piping

    Piping 5.2.1 General 1. Carry out sufficient air blowing or flushing of tubing and connectors to remove foreign matter from inside surfaces prior to connecting them with the pump. 2. Tube connections should be done such that the extra load of piping is not applied to the pump, use pipe supports as necessary.
  • Page 15 2. Install a filter or strainer with low piping resistance on the suction piping to block the entrance of solid particles or wafer fragments. CAUTION! Wafer fragments inside the pump may get stuck in the bellows and cause damage. If solid matter clogs the pump's valves, internal suction or discharge volume may be affected with the normal checking function disabled.

  • Page 16: Air Piping

    5.2.3 Air Piping It is critical that all pneumatic piping and components be sized according to the porting of the pump. Full port components with matching effective cross-sectional area are recommended. 1. Effective cross-sectional area indicates the capacity to allow air to flow freely. When air is sent through a pipe, the air cannot run totally through the actual cross-sectional area of the pipe due to the negative effect of the piping resistance.
  • Page 17 2. Install a relief type regulating valve: Fluctuation of supply air pressure results in fluctuation of the pump stroke rate as well as discharge volume. Install a regulating valve to maintain the air pressure at a fixed level. Select the regulator based on the air consumption rate of the pump.

  • Page 19: Wiring Instructions

    Wiring instructions 5.4.1 General A. Extension of leak detector electrode wire: Keep the resistance value at 5K ohms or below. A resistance greater than the above may make it impossible to detect a conductivity change between the leak detection electrodes. (This is dependent on the controller system.) B.

    5.4.5 Wiring for proximity sensor CAUTION! The proximity sensors of the F series pump have three leads. Faulty wiring may cause the proximity sensor to short circuit. Carry out the wiring carefully and accurately. • Connect the leads of proximity sensor A with terminals 6, 7, and 8 respectively of the controller. •...
