Product Description
Pneumatic diaphragm pump:
also called air-operated diaphragm pump (AODD pump), is a type of positive displacement pump that uses compressed air as a power source to move fluids. These pumps are widely used in various industries for handling a range of fluids, including aggressive chemicals, slurries, viscous materials, and even delicate solutions.

The pump bodies can be made from metals (such as stainless steel, aluminum) or non-metals (like polypropylene or PVDF), depending on the application requirements.
Applications:
Chemical Processing:
Ideal for transferring corrosive and abrasive chemicals due to their robust and corrosion-resistant design.
Food and Beverage:
Suitable for sanitary applications, where gentle handling of fluids is necessary to maintain product quality.
Mining and Construction:
Used for dewatering and transferring slurries, mud, and other heavy-duty fluids.
Pharmaceuticals:
For transferring sensitive or hazardous fluids, as they can be designed to meet stringent hygiene standards.
Oil and Gas:
Used for transferring fluids in offshore and onshore operations, especially where explosion-proof equipment is required.
Advantages:
Self-Priming:
Capable of priming itself even when dry, which allows for easy startup and reliable operation.
Variable Flow and Pressure:
The flow rate and pressure can be easily adjusted by regulating the air supply, offering great flexibility.
Run-Dry Capability:
Unlike many other pumps, pneumatic diaphragm pumps can run dry without damage, making them suitable for handling unpredictable flow conditions.
Safe for Hazardous Environments:
Because they are air-driven, these pumps are inherently explosion-proof and safe for use in flammable or volatile environments.
