Aluminum Alloy Diaphragm Pumps
Air-Operated Double Pneumatic Diaphragm Pump
The Air-Operated Double Pneumatic Diaphragm Pump is a highly reliable and versatile fluid transfer solution widely used across chemical, coating, wastewater, and industrial processing applications. The following points highlight its core advantages:
Leak-Free and Environmentally Safe
The pump separates the driving mechanism from the fluid through a diaphragm, completely eliminating the risk of shaft seal leakage. This ensures safe and contamination-free operation, making it ideal for transferring toxic, hazardous, flammable, or valuable liquids.
nice Media Compatibility
The pump can handle a wide range of media, including liquids containing solid particles, high-viscosity fluids, and corrosive substances such as slurries, paints, and acid or alkali solutions. Wetted parts can be made from various materials such as plastic, stainless steel, or ceramic, allowing precise compatibility with specific process requirements.
Outstanding Self-Priming Capability
The diaphragm pump can start without pre-filling and automatically draw liquid from below its installation level. With a suction lift of several meters, it performs efficiently in operations requiring frequent starts or the transfer of liquids from underground or remote containers.
Easy Flow Rate Adjustment
Flow rate can be conveniently controlled by regulating air pressure or stroke frequency. This wide adjustment range ensures flexibility in adapting to different working conditions or process demands, making it suitable for precise dosing or variable flow applications.
