Product Dewspiption
The Meibao MQ50 Series Plastic Air Operated Diaphragm Pump is a high-flow, corrosion-resistant fluid transfer solution engineered for handling aggressive chemicals, solvents, and abrasive fluids. Powered by compressed air without electrical components, this pump is intrinsically safe for handling flammable and explosive media.
Constructed from high-quality engineering plastics such as Polypropylene (PP) and PVDF, it provides excellent resistance to a wide range of acids and alkalis.
Featuring a no-shaft-seal design, self-priming capability up to 8m (wet), and the ability to run dry without damage, the MQ50 series ensures reliable, leak-free, and maintenance-friendly operation for chemical processing, electroplating, PCB manufacturing, and wastewater treatment 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.
