Hydraulic Oil Magnetic Pneumatic Air Diaphragm Pump

Hydraulic Oil Magnetic Pneumatic Air Diaphragm Pump

one.QBY Air Operated (CZPT) Double Diaphragm Pump is a constructive displacement pump, adopting compress air, smoke and market exhaust gasoline as electrical power supply.

two. It has two diaphragms, the compressed air arrive to the pump entire body to travel the pump in the constant motion of sucking and releasing, so it can pump the liquids effortlessly by this theory. Also it is quite risk-free in hazardous environment because it has no electrical motor.

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