What are the main advantages of an ARO double diaphragm pump?

ARO double diaphragm pumps are known for their ability to handle a wide range of fluids, including viscous, abrasive, and shear-sensitive materials. They offer good suction lift and can run dry without damage.

Is this pump suitable for food processing applications?

While AODD pumps are used in food processing, suitability depends on the wetted materials of construction and specific certifications. Buyers should confirm the exact material specifications and any relevant food-grade compliance with the seller.

What kind of maintenance does an AODD pump typically require?

Routine maintenance commonly involves checking and replacing diaphragms, balls, and seats, along with inspecting the air valve assembly. The frequency depends on the fluid being pumped and operational hours.

Can this pump handle solids?

AODD pumps are generally capable of handling some solids in suspension, with the maximum solid size depending on the pump's design and valve clearances. Buyers should confirm the specific solids handling capacity with the seller.

What is the typical operating pressure range for an ARO AODD pump?

Operating pressure for these pumps is directly related to the supplied air pressure, typically up to 7 bar (100 psi) or sometimes higher, depending on the model. The discharge pressure will be approximately equal to the air inlet pressure.

ARO double diaphragm pumps are known for their ability to handle a wide range of fluids, including viscous, abrasive, and shear-sensitive materials. They offer good suction lift and can run dry without damage.

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.
