The Meibao MQ15/20 Series Aluminum Alloy Air Operated Diaphragm Pump is a high-flow, heavy-duty fluid transfer solution engineered for demanding industrial applications requiring corrosion resistance and explosion-proof operation. Powered by compressed air without electrical components, this pump is intrinsically safe for handling flammable and explosive media. Constructed with a lightweight aluminum alloy pump body, it offers an excellent balance of durability, portability, and corrosion resistance. Featuring a no-shaft-seal design, self-priming capability up to 7.6m, and the ability to run dry without damage, the MQ15/20 series ensures reliable, leak-free, and maintenance-friendly operation for chemical processing, wastewater treatment, and viscous fluid transfer applications.

Explosion-Proof Operation

Powered by compressed air without electricity, the pump is intrinsically safe and can transport flammable and explosive media .

Dry-Run Capable
The pneumatic diaphragm design allows the pump to run dry without damage to internal components, enhancing reliability .

Leak-Free Construction

No dynamic seals or impellers, minimizing the risk of leakage and reducing shear force on the fluid, preserving material integrity .

Corrosion-Resistant Materials

Wetted parts available in Polypropylene, Polyformaldehyde, and PVDF, offering superior resistance to aggressive acids, alkalis, and chemicals .

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.

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.
