Air-Operated Double Diaphragm Pump from China
An air-operated double diaphragm pump uses compressed air to drive two flexible diaphragms, creating reciprocating motion for pumping liquids without internal moving parts contacting the fluid. It falls under HTS 8413.50.0050 as a diaphragm pump, a type of reciprocating positive displacement pump designed for handling corrosive or abrasive liquids in industrial applications.

Import Tips
• Verify pump displacement capacity and material construction (e.g
• PVDF, stainless steel) match declared specifications to avoid reclassification
• Provide detailed technical specs including max pressure and flow rate; ensure CE or ATEX certification for hazardous location use
