What are the main advantages of an air-operated double diaphragm (AODD) pump?

AODD pumps are self-priming, can run dry without damage, handle solids well, and offer excellent chemical compatibility due to various material options. They also provide gentle product handling.

Is this pump suitable for flammable liquids?

Many AODD pumps are ATEX compliant, making them suitable for hazardous and flammable liquids. Buyers should confirm the specific ATEX rating of this unit with the seller.

What maintenance is typically required for an AODD pump?

Routine maintenance typically involves checking diaphragms, valve balls, and seats for wear, and ensuring the air motor is free from contamination. Diaphragms are wear parts and require periodic replacement.

Can this pump handle abrasive materials?

Yes, AODD pumps are commonly used for abrasive slurries due to their design, which minimises wear on critical components. The material construction of the wetted parts is crucial for abrasive applications.

What is the maximum discharge pressure for an ARO AODD pump?

The maximum discharge pressure for ARO AODD pumps is typically equal to the supplied air pressure, commonly up to 7 bar (100 psi).

Typical context for this category of equipment. Always confirm specifics with the seller.

Transferring abrasive slurries in mining and construction.
Pumping viscous chemicals in manufacturing processes.
Handling food-grade liquids and sauces in food processing.
Dewatering sumps and trenches in industrial settings.
Metering and dosing applications for various fluids.

Typical flow rate: For this class of equipment, flow rates typically range from 20 to 1,000 litres per minute, depending on pump size and air supply.
Power supply: Air-operated double diaphragm pumps are pneumatic, requiring a compressed air supply, typically between 2 to 7 bar (30-100 psi).
Material compatibility: Units of this type commonly feature wetted parts in polypropylene, PVDF, stainless steel, or aluminium, with various diaphragm and ball valve materials for chemical compatibility.
Port sizes: Commonly found port sizes for ARO double diaphragm pumps range from 1/4 inch to 3 inches NPT or BSP, depending on the model.
Mobility: This specific unit is mounted on a stainless mobile stand, which is beneficial for applications requiring portability within a facility.
Viscosity handling: These pumps are well-suited for transferring fluids with viscosities up to approximately 20,000 cP, though performance varies with specific fluid properties.

AODD pumps are self-priming, can run dry without damage, handle solids well, and offer excellent chemical compatibility due to various material options. They also provide gentle product handling.

Diaphragm pumps are generally valued for their reliability and versatility across laboratory and pharmaceutical applications. Buyers typically prioritise condition of the diaphragm itself, seals and valve integrity when purchasing used units. Industry sentiment favours their gentle handling of sensitive fluids, low maintenance requirements and ability to manage viscous or abrasive media. Common strengths include self-priming capability, compact design and suitability for both suction and discharge applications. Durability remains a key selling point.
