Got Questions? We’ve Got Answers

What is an AODD pump?

An Air Operated Double Diaphragm (AODD) pump is a positive displacement pump that uses compressed air to move fluids via two flexible diaphragms.

How does an AODD pump work?

It operates using compressed air that alternately fills and exhausts chambers behind two diaphragms, creating suction and discharge action to move fluid.

What are the key advantages of AODD pumps?

• Self-priming
• Can run dry without damage
• Handles viscous, abrasive, and shear-sensitive fluids
• Explosion-proof (no electricity required)
• Portable and easy to maintain

What types of fluids can AODD pumps handle?

AODD pumps can handle:
• Chemicals (acids, solvents)
• Slurries and abrasive fluids
• Oils and fuels
• Food and pharmaceutical liquids
• Wastewater and sludge

Are AODD pumps self-priming?

Yes, they are highly self-priming and can lift fluid from dry suction conditions.

What industries commonly use AODD pumps?

• Chemical processing
• Water & wastewater treatment
• Food & beverage
• Pharmaceuticals
• Paints & coatings
• Mining and construction

What materials are AODD pumps made from?

Common materials include:
• Polypropylene (PP)
• PVDF
• Aluminum
• Stainless Steel
• Cast Iron

What are the limitations of AODD pumps?

• Lower efficiency compared to electric pumps
• Pulsating flow (may require dampener)
• Requires compressed air supply
• Limited high-pressure capability

Do AODD pumps require lubrication?

Most modern AODD pumps are designed to operate without lubrication (oil-free air), but some models may require it depending on design.

Are AODD pumps safe for hazardous environments?

Yes, since they operate on compressed air and do not use electricity, they are suitable for explosive or flammable environments.

How do I select the right AODD pump?

Consider:
• Flow rate and pressure requirements
• Fluid type (corrosive, viscous, abrasive)
• Temperature
• Solid handling needs
• Material compatibility

How energy-efficient are AODD pumps?

They are generally less energy-efficient than electric pumps due to compressed air usage.
