Pneumatic Plastic Chemical Diaphragm Pump Membrane With 135L/Min
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.

Application:
It is widely applied in waste water treatment, chemical industry,
petrochemical
industry, painting, ceramics, environmental protection, printing
and dyeing, etc. to deal with all kinds of
corrosive, volatile, flammable, poisonous fluids with particles and
high viscosity.
Working Principle
In the two symmetrical pump chamber equipped with a diaphragm,
which is connected by a center couplet stem. Compressed air comes
in from pump inlet valve, and enter into one cavity, push the
diaphragm movement, and gases emitted from another cavity. Once to
the destination, gas distribution components will automatically
compressed air into another chamber, push the diaphragm to the
opposite direction, thus make two diaphragm continuous
synchronization to reciprocating movement.
Compressed air goes into the valve, make the diaphragm to the right
movement, and chamber suction make medium enter into, push the ball
into the room, ball valve shuts down due to inhalation, Mediums
discharged by extrusion, and opened the ball valve and at the same
time close the ball valve, prevent back flow, thus to make medium
ceaseless from the entrance inhaled, exit eduction.
