Diaphragm pump Diaphragm pump QBY is double diaphragms model. Also it can be called air operated double diaphragm pump(A.O.D.D pump). Application of this pump is very wide. From normal water, oil to chemical, acids, base, etc by using different diaphragms. Pump has good self-priming function, and may pump high viscosity liquids, foodstuff, etc. It is a very convenient pump in all aspects. QBY has two models with same specifications, only inlet and outlet are different. QBY1 has inlet and outlet on one side, while QBY-2 in the middle of casing. QBY is old model, QBY-k is new pump generation. Casing can be made of cast iron, aluminum alloy, PP platic, stainless steel and diaphragm can be normal PP and PTFE for corrosive and non corrosive liquids. It is a popular pump with multifunction.
