AODD Pumps (Air Operated Double Diaphragm Pumps)

Versatile Diaphragm Pumps for Industrial & Hazardous Environments

Air Operated Double Diaphragm (AODD) pumps are positive displacement pumps designed for handling viscous, abrasive, and solid-laden fluids. Their self-priming capability and air-driven operation make them suitable for hazardous areas.

Typical Applications

• Tank unloading
• Slurry and solid-laden media transfer
• Portable pumping systems
• Chemical transfer in hazardous areas

Technical Specification Overview – AODD Pumps

Engineering Selection Approach

For AODD pump applications, selection is based on:

• Required flow rate
• Air supply pressure & availability
• Solid particle size & slurry concentration
• Fluid viscosity
• Chemical compatibility of diaphragm material
• Installation layout (suction lift / flooded suction)
• Pulsation requirements
• Noise & vibration considerations
• Hazardous area compliance

Particular emphasis is placed on diaphragm material selection and air efficiency for continuous operation.
