PTFE Lined Diaphragm Pump

PTFE Lined Diaphragm Pump

one.QBY Air Operated (CZPT) Double Diaphragm Pump is a good displacement pump, adopting compress air, smoke and market exhaust gas as energy source.

two. It has two diaphragms, the compressed air occur to the pump physique 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 quite protected in dangerous setting because it has no electric 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 merits of self-priming pump, diving pump, protect pump, slurry pump and impurity pump etc.
