Compact Air Operated Diaphragm Pump Pneumatic Driven Diaphragm Pump
Air Operated Diaphragm Pump Introduction
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.

Air Operated Diaphragm Pump Main Advantages
1, Due to the use of air power, the flow automatically changed according to export resistance. Which is suitable for high viscosity fluid.
2, In inflammable and explosive environment, the pump is reliable and low cost, won't produce spark and not overheat,
3, The pump volume is small, easy to move, no foundation needed, convenient installation and economy. Can be used as mobile conveying pump.
4, Where there are dangers, corrosive materials processing, diaphragm pump can be separated completely with outside.
5, The pump shearing force is low, physical effect to medium is small, can be used for conveying unstable chemistry fluid.
