AODD PUMPS

AODD Pumps (Air Operated Double Diaphragm Pumps) If your industry needs transfer applications frequently and handles different types of feeds, like slurries, sludges, shear, abrasive, and sensitive fluids, you should install a type of positive displacement pump. Here comes the role of AODD Pumps, which are robust and reliable. These pumps consist of two different pumping chambers, which fill alternatively and discharge via flexible diaphragm movement.

The design of Air Operated Double Diaphragm Pumps is according to an air valve located inside the central chamber of the pumps. Air enters the air valve and directs it to a particular side of the diaphragm to create a vacuum on one side and compress the air diaphragm on the other side. Delivery manifolds, suction, central air valve, diaphragms, seats, and balls are primary parts of the diaphragm of AODD pumps. These components perform their functions similarly to valves inside the pump.

Whenever the inside of the pump creates a vacuum in its one diaphragm, it rises the balls on its suction side from the seats to let the fluid enters the diaphragm. Simultaneously, balls close to the pump's discharge manifold seal against the pump seats. In the compressed opposing diaphragm, fluid will push the ball against its seats close to the manifold of the suction, and the discharge manifold balls will not seal the outlet. Accordingly, the fluid expels from the discharge manifold to repeat the cycle continuously.

Air Operated Double Diaphragm Pumps are useful as front-step transmission systems of any liquid and solid separation device. These pumps are also useful to suck grinding materials, glazed slurries of porcelain and tiles, paint materials, glue, pigment, adhesives, and various types of flammables. AODD pumps may even suck toxic, corrosive liquids, strong acids, and volatile liquids. Other common applications of the pump are sucking tomato slurry, peanuts, pickles, chocolates, red sausages, syrups, and hops.

WORKING PRINCIPLES

There installs each diaphragm in both aligned working cavities (A) & (B), which can be connected together with a central coupling lever. The compression air enters the air distribution valve from the air entrance of the pump, draw the compression air into one cavity through the air distribution mechanism, push out the diaphragm movement in the cavity. The gas in another cavity will be drained.

Once reaching the stroke terminal, the air distribution mechanism will automatically draw the compression air into another working cavity, push out the diaphragm to move towards the opposite direction, so as to let the both diaphragms continuously reciprocate motion in synchronism.

The compression air enters the air distribution valve from (E) shown as the diagram, let the diaphragm piece move towards the right direction. And the suction force in (A) chamber lets the medium flow into from (C) entrance, push out the ball valve (2) to enter (A) chamber, the ball valve (4) will be locked due to the suction force; The medium in (B) chamber will be pressed, push out the ball valve (3) to flow out from the exit (D). Meanwhile, let the ball valve (1) close, prevent backflow. Such movement in circles will let the medium uninterruptedly suck from (C) entrance and drain from (D) exit.

Working Principles

MAIN USAGE
