Air-operated double diaphragm (AODD) pumps are a cornerstone of fluid handling systems across industries, offering safe, simple, and efficient pumping of a wide range of liquids. Whether you’re moving corrosive chemicals, viscous slurries, or sensitive fluids, choosing the right AODD pump manufacturer is key to maintaining uptime, ensuring safety, and improving long-term system performance.

At MultiTorque, we understand the value of dependable equipment. That’s why we stock, supply, and support AODD pumps from the world’s leading brands—and back it all with expert service. In this article, we’ll break down what to look for in an AODD pump manufacturer, explore the industries that rely on these pumps, and explain how MultiTorque can help you get the right solution the first time.

What Is an AODD Pump?

An air-operated double diaphragm (AODD) pump uses compressed air to power two flexible diaphragms that move fluid through check valves. The design makes them ideal for applications where electricity is hazardous, portability is essential, or the fluid is too abrasive, volatile, or thick for traditional pump types.

Key Advantages:

• Run-dry capability
• Self-priming
• Safe for hazardous environments (non-electric)
• Handles solids and viscous materials
• Low maintenance with few moving parts

These features make AODD pumps especially popular in industries like mining, oil & gas, chemical processing, wastewater treatment, food & beverage, and general manufacturing.

What Makes a Good AODD Pump Manufacturer?

When sourcing AODD pumps, not all manufacturers are created equal. Here are the top factors to consider:

1. Proven Reliability

A reputable AODD pump manufacturer will have a long track record of consistent quality. Brands like Wilden, Graco, and Yamada are globally recognized for robust designs and consistent performance in harsh operating environments.

2. Broad Range of Sizes & Materials

A good manufacturer offers a wide range of pump sizes and diaphragm materials—such as Santoprene, PTFE, Viton, Buna-N, and EPDM—to handle different chemicals and temperatures. This flexibility ensures compatibility with your exact application.

3. Global Certifications

Look for compliance with international standards like ATEX, FDA, or ISO 9001. These certifications provide assurance that the pump meets safety and quality benchmarks.

4. Serviceability & Support

The best AODD pump manufacturers offer easy-to-maintain designs and global support networks. But even more critical is your local supplier. That’s where MultiTorque comes in—with workshop servicing, parts availability, and technical support across Australia.

Why Australian Industries Choose AODD Pumps

AODD pumps are widespread across Australia, especially in demanding environments. For example:

• Mining & Dewatering: Their ability to handle slurry and grit makes them indispensable in harsh underground conditions.
• Chemical Plants: Non-electric and corrosion-resistant designs reduce risk.
• Wastewater Facilities: The ability to pump solids-laden fluids efficiently and reliably is a huge advantage.
• Agriculture & Food Processing: Sanitary versions of AODD pumps are used for dairy, juices, sauces, and more.

In each of these sectors, the pump is only as good as the manufacturer behind it—and the supplier who backs it up.

How to Choose the Right AODD Pump

When you’re selecting an AODD pump or comparing manufacturers, here are a few key questions to ask:

• What fluid are you pumping? (chemicals, sludge, food-grade?)
• What size solids need to pass through?
• What is your flow rate and pressure requirement?
• Will it be in a hazardous or ATEX-rated area?
• Is portability or weight a factor?

MultiTorque can guide you through all of these questions and provide expert recommendations backed by real-world experience.
