Product Name: Iron Cast Pneumatic Diaphragm Pump (QBY-40) Model NO.: QBY Performance: Corrosion Diaphragm Material: NBR/ PTFE Function: Diaphragm Valve Body Type: Diaphragm Power: Pneumatic Material: Cast Iron and Stainless Steel Certification: ISO9001:2008, CE Place of Origin: China Brand Name: Yonjou Model Number: Qby-40 Theory: Pneumatic Structure: Diaphragm Pump Usage: All Kinds Water Oil Chemicals Standard or Nonstandard: Standard Fuel: None Pressure: High Pressure Trademark: YonJOU Transport Package: Plywood Case Specification: CE ISO9001 Origin: China HS Code: 841311000 Product Description Summarize:1.QBY Cast Iron Stainless Steel PVDF PTFE Teflon Air Operated (Pneumatic) Double Diaphragm Pumpis a positive displacement pump,adopting compress air, smoke and industry exhaust gas as power source.2. It has two diaphragms, the compressed air come to the pump body to drive the pump in the constant action of sucking and releasing, so it can pump the liquids easily by this principle. Also it is very safe in dangerous environment since it has no electric motor.3. QBY air operated double diaphragm pumps can not only transfer the flow liquid, but alsocan transfer some uneasy flowed medium, with the merits of self-priming pump, diving pump, shield pump, slurry pump and impurity pump etc.Product details:Working Principle:Double Diaphragms, PneumaticMain applications: Oil, Water, Chemical, etc.Driver:Air OperatedMax.permissible fluid temperature:150°C(302°F)Type of connection:Flange, Thread, Quick coupledInstallation position:Connect to compressorCasing parts material:C.I, S.S, PP, Aluminium, PVDF, PTFE linningMaximum grain diameter:10mm (3/8inch)Maximum drive rating:7kgf/cm2Maximum caliber: 100mm(4inch)Maximum discharge-side pressure:6kgf/cm2Maximum head:50m(164ft)Flow rate range: 0.8-30m3/h(3.5-132US.GPM)Performance data:ModelSize(")Capactiy(m3/h)Head(m)SuctionHead (m)MaxGrain Dia.(mm)AirPressure (Kgf/cm2)QBY-103/8"0~0.80~60517QBY-151/2"0~151QBY-251"0~2.472.5QBY-401-1/2"0~874.5QBY-502"0~1278QBY-652-1/2"0~1678QBY-803"0~24710QBY-1004"0~30710Company information:Zhejiang Yonjou Technology Co., Ltd is one of the leading manufacturers and exporters in the field of industry pumps with manufacturing facilities in mainland China.
