Pneumatic Diaphragm Pump Double Diaphragm Pump

Pneumatic Diaphragm Pump Double Diaphragm Pump

1.QBY Air Operated (CZPT) Double Diaphragm Pump is a constructive displacement pump, adopting compress air, smoke and business exhaust fuel as electricity resource.

2. It has two diaphragms, the compressed air appear to the pump human body to travel the pump in the continuous motion of sucking and releasing, so it can pump the liquids effortlessly by this principle. Also it is really safe in harmful setting because it has no electrical motor.

three. QBY air operated double diaphragm pumps can not only transfer the flow liquid, but also can transfer some uneasy flowed medium, with the deserves of self-priming pump, diving pump, defend pump, slurry pump and impurity pump and many others.
