1 inch air operated double diaphragm pump can pump a variety of toxic, flammable, volatile liquid, slurry, high viscosity fluids, corrosive liquids and paint. It also can be used for cleaning sediment contaminant in shaft, tunnels and sewers.
Features
Pneumatic dual diaphragm pump can transport high temperature media up to 130 ℃.
Adopt pilot operated type air valve to eliminate the AODD pump downtime and extend its life span.
It is designed with multiport to help you install it easily.
Air powered diaphragm pump can be used as a movable-type material transfer pump because it has such advantages as small in size, easy moving, no need base, small occupied area and easy installation.
It can be externally connected to an electromagnetic valve for remote control. And the reversing valve requires no lubrication.

Applications
Tips: Air Operated Double Diaphragm Pump Working Principle
There installs each diaphragm in both aligned working cavities A & B of the AODD pump, which can be connected together with a central coupling lever. The compressed air enters the air distribution valve from the air entrance of the pneumatic diaphragm pump, draws the compressed air into one cavity through the air distribution mechanism, and 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 compressed air into another working cavity, push out the diaphragm to move towards the opposite direction, so as to let both diaphragms continuously reciprocate motion in synchronism. The compressed air enters the air distribution valve from E shown as the diagram, letting 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.
