What types of products can an Aro AODD pump handle?

Aro AODD pumps are highly versatile and can handle a wide range of food products, from thin liquids like juices to viscous sauces, purees, and even products containing soft solids.

Are these pumps suitable for hygienic applications?

Yes, many Aro AODD pumps are designed with hygienic considerations, featuring smooth internal surfaces and appropriate material choices for food contact and ease of cleaning. Buyers should confirm specific certifications for this unit.

What are the main advantages of an AODD pump?

Key advantages include self-priming capabilities, the ability to run dry without damage, gentle product handling, and suitability for hazardous or abrasive fluids due to their seal-less design.

What maintenance is typically required for an AODD pump?

Routine maintenance typically involves inspecting and replacing diaphragms, balls, and seats as they wear, along with checking air valves and seals. The frequency depends on usage and the products being pumped.

Can this pump be used for metering or dosing applications?

While AODD pumps can be used for transfer, for precise metering or dosing, they are often paired with flow meters or control systems to ensure accuracy, as their flow rate can fluctuate with air pressure.

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

Transferring viscous liquids and slurries in food production.
Handling shear-sensitive products like yoghurts or fruit purees.
Dosing ingredients in batch processing operations.
Emptying containers and IBCs of food-grade liquids.
Circulating cleaning-in-place (CIP) solutions.

Typical capacity: For this class of equipment, capacities commonly range from 50 to 1000 litres per minute, depending on the model and application.
Power supply: Air operated double diaphragm (AODD) pumps are typically powered by compressed air, requiring a suitable air compressor and filtration system.
Construction materials: Wetted parts are commonly made from food-grade stainless steel (e.g., 316L) and various elastomers (e.g., PTFE, Santoprene, EPDM) suitable for food contact.
Operating pressure: These pumps typically operate with air pressures between 2 to 7 bar, generating corresponding fluid discharge pressures.
Port sizes: Commonly found on units of this type are inlet and outlet port sizes ranging from 1 inch to 3 inches, often with hygienic connections.
Mounting: This unit is mounted on a stainless steel stand, which is typical for mobile or semi-permanent installations in food processing environments.

Aro AODD pumps are highly versatile and can handle a wide range of food products, from thin liquids like juices to viscous sauces, purees, and even products containing soft solids.

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.
