Pneumatic Diaphragm Pumps

Qeehua pneumatic diaphragm pumps are designed for reliable chemical transfer, circulation, and unloading in demanding industrial environments. Driven by compressed air, they support self-priming operation, dry-running conditions, and stable handling of corrosive, abrasive, or particle-containing liquids.

The diaphragm pump range includes non-metallic and metallic constructions such as polypropylene, PVDF, aluminum alloy, cast iron, and stainless steel. This gives customers flexible material choices for acids, alkalis, solvents, wastewater, plating liquids, and general chemical transfer duties.

They are widely used in electroplating, PCB wet process, surface treatment, wastewater treatment, chemical dosing, unloading, and transfer applications. Qeehua diaphragm pumps help customers improve fluid handling flexibility, reduce leakage risk, and maintain dependable operation in harsh process conditions.
