Introduction to Air-Operated Double Diaphragm Pumps (AODD)
Air-Operated Double Diaphragm (AODD) pumps, commonly known as diaphragm pumps, are a versatile and reliable solution widely used across various industries for handling challenging fluids.
These pumps operate through the simple yet effective principle of reciprocating diaphragms driven by compressed air, making them ideal for applications where electricity is impractical or hazardous environments require safe, non-sparking operation.
AODD pumps are also volumetric. Due to their positive displacement design, AODD pumps can precisely move a specific volume of fluid per cycle, regardless of viscosity or pressure fluctuations. This feature makes them highly effective for metering, dosing, and transferring fluids that require consistent and controlled flow rates, enhancing process accuracy and reliability.

AODD pumps are known for their ability to handle a wide range of fluids, from highly viscous materials to corrosive chemicals, abrasive slurries and even shear-sensitive products. Their unique design enables dry running, self-priming and the ability to handle solids-laden fluids that traditional pumping technologies can struggle with.
Designed for flexibility, AODD pumps are found in installations from chemical processing to wastewater treatment, food and beverage production, and beyond. Their simplicity, reliability, and simple maintenance requirements make them a good choice for technical personnel seeking robust and adaptable fluid handling solutions.
This introduction provides a foundation for understanding AODD pumps, while the following sections delve into their working principles, typical installations, selection criteria, and industry-specific applications.
Important
Although diaphragm pumps use compressed air, which is safe and flexible, this can be a costly solution for pumps operating continuously, as other pump technologies often consume less or less expensive energy.
So it’s important to make your calculations based on your intended use.
