Summarize:
1.QBY50-60 Cast Iron Stainless Steel PVDF PTFE Teflon Air Operated (Pneumatic) Double Diaphragm Pump is 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 also can transfer some
uneasy flowed medium, with the merits of self-priming pump, diving pump, shield pump, slurry pump and impurity
pump etc.
