About Air Operated Diaphragm Pumps
Transfer liquids in challenging conditions, no electricity needed
Hunter Pumps is a leading supplier in Australia of high-quality, energy-efficient, air-operated diaphragm pumps from world-class trusted manufacturers.
An Air Diaphragm Pump (or AODD pump) operates using compressed air rather than an electrical motor.
In applications like mining or other industrial activities, the fluids that need to be handled may be flammable, meaning that pumps run by an electric motor are not safe or recommended.
Air Operated Diaphragm Pumps are also useful when electricity sources are scarce or unavailable in an area. They also perform well when pumping high-viscosity liquids, transferring chemicals, or dewatering coal mines.

ARO pumps are designed for maximised flow rates with minimised pulsation and air consumption. With its bolted, leak-free, and modular construction, ARO pumps are safe to use even in harsh conditions, built to last to reduce downtime or repair costs.
Graco is synonymous with reliability. Thanks to their pneumatic motor, these pumps are particularly favoured in potentially explosive environments. Another significant advantage lies in their ability to run dry or shut off without harm.
Furthermore, they are adept at working with various substances, be they corrosive, abrasive, or of high viscosity. The ability to transfer large particles without causing damage enhances their appeal.
Wilden pumps are celebrated for their durability, reliability, energy efficiency, and cost-effectiveness blend. They can transfer an array of fluids, from the thinnest to the most viscous and from the cleanest to those laden with particulates. The Engineered Air Distribution System (ADS) is a standout feature crafted to minimise air consumption.
Moreover, the Pro-Flo SHIFT Series by Wilden offers remarkable advantages – up to 60% savings in air consumption and an upsurge of up to 30% in flow compared to competitors. Their versatility makes them suitable for a broad spectrum of industrial applications.

Applications of AODD Pumps
AODD Pumps are like the all-rounder players in a team. They fit in many places and do the job well.
Here's an insight into the applications of Air Operated Diaphragm Pumps
Chemical Industry
- Fluid Handling: AODD pumps efficiently transfer raw materials and derivatives, showcasing unmatched adaptability to varying fluid types and viscosities.
- Versatility: These pumps excel in the chemical industry due to their capacity to handle diverse fluids and solids and their chemical resistance.
Water Management
- Drainage Solutions: Employed in stormwater management, sump, and tank drainage, ensuring consistent flow and effective water transfer.
- Desalination: Critical in desalination plants, handling the variable flow rates and challenges precisely.
Waste Water Treatment
- Efficient Processing: Central to wastewater treatment processes, handling wastewater and solids, and ensuring fluid inlet and outlet are managed effectively.
Food Processing
- Sanitary Transfer: Essential in the food industry, with food-grade sanitary processing at the forefront. It is ideal for transferring viscous liquids like gels and creams.
Electronics and Pharmaceuticals
- Precision Pumping: The choice for the electronics and pharmaceutical sectors, where precision and consistent flow rates are paramount.
Paint Industry
- Material Transfer: Championed in the paint industry, capable of handling fluids from raw materials to finished products.
Other Noteworthy Applications
- Logistics: Proven in unloading trucks and emptying cisterns.
- Industrial Processes: Used in scrubbers' applications, distillation plants, and filter presses.
- Varied Fluid Handling: Adapted to manage thick fluids, slurry, small solids, and even gels/creams.
Unique Design Advantages
- Operational Efficiency: Simple startup, self-priming capabilities, and resistance to dry running make AODD pumps stand out.
- Gentle Displacement: Ensures the integrity of the pumped material, from liquids to solids.
- Flexibility: No need for control electronics or pricey frequency converters. These pumps adeptly respond to changes in fluid properties.
- Run Dry Capability: Should the liquid source deplete, like an empty tank, AODD pumps can run dry without damage, showcasing their robust design.
