Pneumatic drive bellows pumps FW / FW-H series

Features of FW / FW-H series

High Temperature Transfer

High Pressure Discharge

Long Life

• The use of a thick bellows increases the pumps discharge pressure rating to as high as 0.45 MPa maximum. In addition, the bellows have three to four times longer service life than a diaphragm. This results lower case a substantially reduced downtime.
• This design is commonly used for chemical feed, the FW series can be used in high pressure and medium temperature (10 – 100°C) cleaning systems as well as for the circulation of CMP slurry liquids. The FW-H with its higher temperature capability (10 – 180°C) is ideal for chemical circulation in wafer cleaning applications.
• Easily adaptable fitting capability, the internally formed PFA suction and discharge tubes prevent the accumulation of particles.
• When connected to a special controller, the discharge can be monitored and controlled easily.
• The pump utilizes a built in proximity sensor driven control system to switch an external air solenoid valve. Leak sensors are also included as standard equipment.
