Product Dewspiption
The Meibao MQ80 Series Stainless Steel Air Operated Diaphragm Pump is a high-flow, heavy-duty fluid transfer solution engineered for the most demanding industrial applications requiring superior corrosion resistance, sanitation, and durability. Constructed from high-quality stainless steel 304, 316, or 316L, this pump offers exceptional resistance to aggressive chemicals, high temperatures, and corrosive environments. Powered entirely by compressed air without electrical components, it is intrinsically safe for handling flammable, explosive, or hazardous media. Featuring a no-shaft-seal design, self-priming capability up to 5m, and the ability to run dry without damage, the MQ80 series ensures reliable, leak-free, and maintenance-friendly operation for chemical processing, mining, wastewater treatment, and heavy industrial fluid transfer applications.
Superior Corrosion Resistance & Durability
Constructed from high-quality stainless steel 304, 316, or 316L with high-temperature wax precision casting, providing excellent corrosion resistance, high strength, and a smooth, sanitary surface .
Explosion-Proof & Safe Operation Powered entirely by compressed air, eliminating the risk of sparks and ensuring safe operation in flammable, explosive, or hazardous environments without electrical components .
Versatile Fluid Handling
Capable of handling fluids with high viscosity, high specific gravity, and containing solid particles up to 2.5mm diameter. Flow and head can be adjusted by changing the intake air volume and pressure .
Superior Self-Priming Performance
Dry self-priming head up to 4m, wet self-priming head up to 7.6m, enabling efficient fluid transfer without manual priming .
Long Service Life & Low Maintenance
Advanced diaphragm design with increased arch height reduces edge stress, and precision-machined valve balls ensure excellent sealing. Wear parts typically require replacement only once a year under normal conditions .
Typical Applications
Chemical Processing: Transfer of acids, alkalis, solvents, and aggressive chemicals .
Wastewater Treatment: Chemical dosing and sludge transfer.
Electroplating & Surface Treatment: Plating solution and chemical bath transfer.
PCB Manufacturing: Etching and developing solution transfer.
