Applications and Advantages of Air Operated Double Diaphragm Pumps

AODD pumps (Air Operated Double Diaphragm pumps) are commonly used around various industries owing to their minimal design and operation efficiency. They are widely known for their versatility with viscous and abrasive fluids. AODD pumps are the top choice when it comes to situations where conventional pumps are most likely to fail.

Let's dive into the wide range of applications and benefits of the AODD pumps. This blog will also look at one of the top air operated double diaphragm pump manufacturers, ARO.

Chemical Processing

When it comes to the chemical processing industry, the abrasive, corrosive and dangerous nature of the fluids being handled calls for specifically designed and manufactured pumps. AODD pumps are required to be capable of functioning in such hazardous conditions effectively. ARO's AODD pumps, like the EXP Series, are ideal for these conditions due to their:

Chemical-resistant diaphragm materials like long-lasting PTFE (which provides double the service life over standard PTFE) and Santoprene, that can handle a wide range of pH levels and viscosities.
Availability in both metallic and non-metallic constructions for enhanced compatibility with various chemicals.

Water and Wastewater Treatment

AODD pumps are frequently used in the water treatment process in the purification as well as decontamination of sewage sludge. They make great constituents in the batch operations of this sector owing to their distinct advantages, demonstrated by ARO’s pumps due to their:

Dry priming and dead-heading capabilities that allow for smooth operation.
Efficiency despite fluctuating water levels or interruptions in flow, common in batch operations.

Food and Beverage

The AODD pumps utilized in the food and beverages industry must maintain robust hygiene standards laid out by regulatory authorities. Typically, food-grade and regulatory authority-approved materials are used. ARO AODD pumps address the needs of the F&B industry with:

Materials that comply with strict food safety regulations, ensuring product quality and consumer safety. ARO’s sanitary pumps offer 20-30% better flow rates than their contemporaries.
Simple designs with minimal moving parts that minimize crevices and allows for thorough cleaning to prevent bacterial growth and contamination.

Pharmaceutical Manufacturing

Akin to the food and beverage industry, pharmaceutical manufacturing calls for precision to help create contamination free, safe to use solutions. AODD pumps are common in almost all processes throughout the production, to handle a variety of materials including pastes, creams, volatile compounds and more. ARO's AODD pumps are particularly suited for pharmaceutical applications because of:

Diaphragms that create a pulsating flow that minimizes shear stress on the delicate solutions and pastes commonly used in pharmaceutical manufacturing.
Models with smooth surfaces and easy-to-clean components, meeting the stringent hygiene requirements of pharmaceutical production.
