QBY Series Cast Iron, Stainless Steel, Teflon Air Operated Double Diaphragm Pump for Food, Oil and Chemical
Pneumatic Diaphragm Pump
1.air operated double diaphragm pump for Food& Chemical, Chemical Resistant 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 also can transfer some uneasy flowed medium, with the merits of self-priming pump, diving pump, shield pump, slurry pump and impurity pump etc.
