Chemical Resistant Air Driven Double Diaphragm Pump Self Priming Submerse Capability

Chemical Resistant Air Driven Double Diaphragm Pump Self Priming Submerse Capability

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.

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.
