Air Operated Diaphragm Pumps

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.

Suitable for general fluid transfer, ARO’s AODD pumps can be used across a wide variety of applications. Whether the fluids are of light or medium viscosity, you can trust an ARO pump to move fluids efficiently without damage, even corrosive or abrasive fluids.

Suitable for general fluid transfer, ARO’s AODD pumps can be used across a wide variety of applications. Whether the fluids are of light or medium viscosity, you can trust an ARO pump to move fluids efficiently without damage, even corrosive or abrasive fluids.

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.

At Hunter Pumps, our association with these brands underscores our commitment to delivering the best to our clientele. Trust in us to provide products that not only meet but exceed industry standards.

Frequently Asked Questions (FAQs)

Routine maintenance intervals can vary depending on your specific application. However, in most cases, conducting routine maintenance once a month is a good practice to ensure optimal pump performance.
Maintaining your diaphragm pump involves understanding its basic components. Start by disassembling and inspecting the pump during maintenance. Familiarity with both the wet/fluid side (components that contact the pumped fluid) and the air side (components that stay dry) is crucial for effective maintenance.
An AODD pump comprises two distinct sections: the wet/fluid side and the air side. The wet/fluid side includes components that come into contact with the pumped fluid, while the air side involves components that interact with the air and are intended to remain dry throughout the operation. Understanding this division is essential for proper pump maintenance and troubleshooting.
A positive displacement pump moves fluid by mechanically enclosing a fixed amount and transferring it through the system. Unlike centrifugal pumps, it directly increases fluid pressure using components like pistons or gears. The pump offers consistent flow rates and is ideal for applications requiring low fluid velocity, such as handling fragile solids.
