What Is a Wilden Pneumatic Pump?

A Wilden pneumatic pump is an air-operated double-diaphragm pump designed to transfer a wide range of fluids safely and efficiently. Instead of using electricity or direct mechanical drives, these pumps operate using compressed air. This makes them particularly safe in hazardous environments where sparks from electrical motors could cause issues.

Wilden pioneered AODD technology, and their pneumatic pumps remain industry leaders thanks to their durability, versatility, and ease of maintenance.

Advantages of Wilden Pneumatic Pumps

The Wilden pneumatic pump stands out for several reasons:

Safety in Hazardous Environments
With no electrical components, pneumatic pumps can be safely used in areas where flammable or explosive materials are present.
Versatility Across Fluids
Wilden pumps can handle everything from corrosive chemicals to viscous slurries, making them suitable for a broad range of applications.
Self-Priming & Dry Run Capabilities
Unlike many other pump types, pneumatic diaphragm pumps can run dry without damage and are self-priming, reducing startup issues.
Ease of Maintenance
Their simple design with minimal moving parts allows for quick repairs and lower servicing costs.
Portability
Many models are compact and lightweight enough to be relocated easily across different sites or applications.

Common Applications of Wilden Pneumatic Pumps

Because of their adaptability, Wilden pneumatic pumps are used across many industries:

Mining: For transferring slurries, tailings, and abrasive fluids.
Oil & Gas: For handling hydrocarbons, drilling muds, and production fluids.
Water & Wastewater: For pumping sludge, effluent, and other challenging fluids.
Chemical Processing: For safely transferring acids, solvents, and corrosive liquids.
Food & Beverage: For pumping syrups, sauces, and shear-sensitive materials where product integrity matters.

Wherever fluid transfer is required, Wilden pneumatic pumps deliver consistent results.

Why Choose Wilden Over Other Pneumatic Pumps?

There are many diaphragm pumps available, but Wilden remains one of the most trusted brands worldwide. The reasons are clear:

Proven Reliability – Wilden’s designs are tested in some of the toughest industries.
High Flow Rates – Their engineering delivers superior efficiency and output.
Material Options – With versions built from aluminium, stainless steel, and polypropylene, Wilden pumps suit a wide range of chemical compatibilities.

At MultiTorque, we’ve seen firsthand how a Wilden pneumatic pump outperforms many competitors in terms of lifespan and reliability.

Servicing and Repairs for Wilden Pneumatic Pumps

While Wilden pumps are built tough, regular servicing is key to long-term performance. A well-maintained Wilden pneumatic pump will keep your operations moving smoothly, while neglected units can fail unexpectedly and cost thousands in downtime.

Typical servicing tasks include:

Inspecting diaphragms and replacing them when worn.
Cleaning or replacing valve balls and seats.
Checking seals and O-rings for leaks.
Ensuring air distribution systems are performing efficiently.

At MultiTorque, we perform all repairs and rebuilds in-house at our workshops in Perth and Brisbane. While we don’t offer on-site pump repairs, our controlled workshop environment allows us to conduct high-precision diagnostics, use genuine spare parts, and restore pumps to near-new performance.
