Thermoplastic / Pneumatic Double Diaphragm Pump Air Operated
Pneumatic Double Diaphragm Pump features:
1. Double Diaphragm Pump Air Operated Double Diaphragm Pump Rubber
Diaphragm for 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.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
Air diaphragm pump(also know as a Membrane pump, air operated double diaphragm pump(AOOD) or pneumatic diaphragm pump)that uses a combination of the reciprocating action of a
rubber,thermoplastic or diaphragm and suitable valves either side
of the diaphragm (check valve,butterfly valves,flap valves,or any
other form of shut-off valves) to pump a fluid.
