Air Operated Stainless Steel Diaphragm Pump / Air Double Diaphragm Pump

SS Air Operated Double Diaphragm Vacuum Pump 8.3bar Self Priming

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.

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.

Application area:
Chemical Industry; Coating Industry; Painting Industry; Dye Industry; Pigment and Textile Chemical Industry; Food Industry; Water treatment Industry; Petroleum Industry; Environmental protection Industry; Pharmaceutical Industry
