Air Operated Double Diaphragm (AODD) Pumps

An Air Operated Diaphragm Pump (AODD pump), also called a pneumatic diaphragm pump, is a positive displacement pump powered by compressed air. It uses a diaphragm driven by an air motor to create suction on one side and discharge on the other, enabling efficient fluid transfer. Unlike a hydraulic pump (using hydraulic fluid) or a water pump (designed for water priming), an AODD pump can handle diverse fluids, often without external water priming, and works well under negative suction. It manages abrasive, corrosive, and viscous fluids, including sludges, slurries, and sewage, with spark-free operation for hazardous environments. Used across industries such as chemical, pharmaceutical, food & beverage, and water treatment, AODD pumps perform self-priming transfer, metering, and slurry handling. Types include single-acting, double-acting, and airless diaphragm pumps. With minimal moving parts, no lubrication needs, and easy maintenance, AODD pumps offer reliable performance for demanding applications

Key benefits include:

• Versatility: Handles sludges, slurries, corrosives, and flammable liquids.
• Self-Priming: Can run dry without damage and self-prime up to 23ft of suction lift.
• Durability: Sealless design ensures leak-free operation with minimal maintenance.
• Safety: Pneumatic operation eliminates electrical hazards, ideal for volatile environments.

AODD pumps are widely used in industries like chemical processing, mining, water treatment, and food production due to their reliability and gentle pumping action.
