QBY/QBK series air operated diaphragm pumps are with sizes vary from 3/8 to 4 inch inlet/outlet.The pump body is made of various material, including stainless steel,PP, NEOPREN, fluorine rubber,PTFE,FEP, etc.which with high quality and good-looking appearance.
QBY/QBK series pneumatic diaphragm pump is the latest type at home currently, Simple structure, easy overhaul, stable transportation of fluid, low vibration, low noise, high self-absorption capacity and transmission fluid viscosity, with many advantages from self-suction pump,submersible pumps,shielded pump,mud pumps, and other transportation machines. This pump adopts the compressed air as the power supply,It can be used to pump and suck up all liquids including various corrosive liquids,volatile,inflammable,explosive and virulent liquids with grains and high viscosity, Its performance parameters are similar as those of German WLLDENPUMPS and American MARIOWPUMPS.
