Advantages of Air-Operated Double Diaphragm Pumps
- Can handle fluids that are:
- Laden with large solids
- High or low viscosity
- Hazardous or abrasive
- Self-priming
- Ideal for maintaining system pressure without stressing its components
- No mechanical seals, gaskets or packing
- Can run dry without damage
- Easily adjustable flow rate and pressure
- Safe discharge pressure: no relief valve required
- Lightweight, compact and easy to move
