Double Air Driven 3 Inch Diaphragm Pump / Gas Powered Diaphragm Pump

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.

Pneumatic Diaphragm Pump Advantages:

Idling ,Self-priming , Submerse capability.
Provide stall-free, ice-free zero leak operation.
Epoxy-coated air section for tough environmental conditions.
Low shear force , not easy to damage the material structure.
Bolt joint design provides even sealing pressure for optimal performance
Modular air valve,low pulsation operation,providing smooth and rapid changeover.
No electricity . It's safe and realiable while using in the flammable and explor place .
Diversity of material,no rotating parts,applicable to various erosive situations.
Can pump corrosive , volatile, flammable, poisonous fluids with particles and high viscosity.
Delivery lift and flow can pass the pneumatic valve open to realize the stepless adjustment
