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.

AODD Pumps can deal with all kinds of corrosive, volatile, flammable, poisonous fluids with particles and high viscosity.

1.The pump can suck the peanut, pickles, tomato slurry, red sausage, chocolate, hops and syrup etc.
2. The pump can suck the paint, pigment, glue and adhesive etc.
3. The pump can suck various glazed slurries of tile, porcelain, brick and chinaware etc.
4. The pump can suck various grinding materials, corrosive agent and clean the oil dirt etc.
5. The pump can suck various toxin and flammable or volatility liquid etc.
6. The pump can suck various wedge water, cement slurry and mortar etc.
7. The pump can suck various strong acid, alkali and corrosive liquid etc.
8. It can be used as a front-step tranmission device of the solid and liquid separation equipmen
