Product Name: Pneumatic Diaphragm Pump, Diaphragm Pumps, Air Diahprahm Pump Model NO.: QBY Performance: Explosion Diaphragm Material: NBR/ PTFE Power: Pneumatic Material: Plastic, Cast Iron, Stainless Steel, Aluminum Certification: ISO9001:2008, CE Certificate: ISO9001:2008 Trademark: YonJou Transport Package: Standard Export Plywood Case Packing Specification: International Origin: China HS Code: 8413110000 Product Description Summarize:1.QBY Stainless Steel Air Diaphragm Pump for Food& Chemical, Chemical Resistant Diaphragm Pump is the new kind of transportation machine, 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 not only can 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, AluminiumMaximum 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)Air Pressure (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"0~30710
