- Process-liquid transfer
- Transfer where air drive is preferred
- Applications requiring liquid-compatible wetted parts
Technical overview
How this range is used.
These are series-level characteristics, not a performance guarantee for a specific model. Confirm flow, head or pressure, power, dimensions, materials, and operating limits against the current datasheet.
- Operating principle
Compressed air alternately moves diaphragms to draw in and discharge liquid. - Configuration
Air-operated, positive-displacement diaphragm pump. - Liquid suitability
Process liquids selected against diaphragm, valve, and wetted-part compatibility. - Typical use
Transfer duties where an air-driven pump is preferred.
Selection information
What we need to size it.
- Liquid composition, viscosity and solids
- Required flow and discharge pressure
- Available compressed-air supply and material compatibility
Technical confirmation
Ask for the current model table and curve.
