ARO Air Operated Diaphragm Pump

ARO diaphragm pumps, recognized globally for advanced air-operated pumping technology, feature a patented air valve system that improves operating efficiency through dead-point-free switching, reduced air leakage, and reliable performance in low-temperature and high-humidity environments.

Unlike conventional pneumatic diaphragm pumps, ARO series pumps are engineered with reinforced diaphragm structures and optimized internal components, reducing maintenance frequency while extending service life. The design enables stable handling of high-viscosity fluids, abrasive materials, and liquids containing solid particles.

Advanced Air Valve Technology

Dead-Point-Free Air Switching

The ARO air valve system is designed to achieve smooth and continuous switching without stopping points during operation.

Advantages include:

• Reduced operation interruption
• Improved pumping stability
• Lower compressed air consumption
• Enhanced overall efficiency

Anti-Icing Performance

In cold and humid working environments, traditional pneumatic pumps may experience air exhaust icing problems.

ARO air valve technology helps reduce freezing risks, allowing stable operation in challenging industrial conditions.

Low Air Leakage Design

Optimized pneumatic control reduces unnecessary compressed air loss, helping improve energy efficiency and reduce operating costs.

Reinforced Diaphragm Design

ARO diaphragm pumps use reinforced diaphragm structures designed for demanding industrial applications.

Benefits include:

• Longer diaphragm service life
• Better fatigue resistance
• Improved temperature tolerance
• Reduced replacement frequency

The simplified internal structure also helps reduce the number of wearing parts and makes maintenance more convenient.
