3 2.1 Operation Sequence 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 throu...

7 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. In addition, to enhance sy...

8 4.2 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...

9 • 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 fa...

10 4.4 Liquid Circulation System Design Recommendations In typical semiconductor wet process liquids, a catalyst such as H 2 O, O 3 or H 2 O 2 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 amo...

11 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 5.1 Installation 1. Pump installation positi...

12 5.2 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 suppor...

13 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 discha...

14 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...
