This series of diaphragm pump is the latest type at home currently. 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, ceramic glaze slurry, berry and glue or for the bottom oil recovery of oil tanker and temporary tank dumpin. Its performance parameters are similar as those of German WLLDENPUMPS and America MARIOWPUMPS. The flow-through parts of the pump body adopt four kinds of material:stainless steel, fluorine rubber, neoprene and /Chemigum fluorine rubber,neoprene and Chemgium fluorine lining .

   QBY series pneumatic diaphragm pump adopts the compressed air, steam and industrial waste gas as the power supply, whose suction lift is 7m,lift head 0-55m and flow 0.8-40m3/h,being stepless adjustable
