The World's Cleanest Factories
Need the World's Cleanest Pumps

Semiconductor fabrication plants  | commonly called "fabs"  | are among the most demanding environments on earth for fluid handling equipment. At nodes measured in nanometers, even a single particle of contamination can destroy an entire wafer, costing tens of thousands of dollars in lost yield. Meibao Pump has spent over two decades engineering pumping systems that operate at the intersection of chemical resistance, contamination control, and absolute reliability.

HF (hydrofluoric acid) is the backbone of semiconductor wafer cleaning and etching processes, and it is also one of the most aggressively corrosive chemicals known to engineering. Most pump materials fail within months in HF service. Meibao's fluorine-lined and PTFE/PVDF wet-end pumps are purpose-built for these media  | with wetted materials that resist HF attack at concentrations up to 49% and temperatures reaching 120°C.

Beyond HF, semiconductor fabs handle a cocktail of aggressive chemicals including HCl, HNO%? H%/O%? phosphoric acid, ammonium hydroxide (NH%%H), NMP (N-Methyl-2-pyrrolidone), and CMP (Chemical Mechanical Planarization) slurries. Each has its own corrosion profile and particulate-generation risk. Meibao engineers select the right material, seal configuration, and drive system for every fluid  | eliminating contamination events before they happen.
