Stainless Steel Air Operated Diaphragm Pumps tend to be general workhorse devices, typically used in transfer applications. SS316 Air Operated Double Diaphragm Pumps are also very much suitable to empty Barrel, Drum, Tanks as it has a capacity to lift the Liquide from 8 Meter negative Suction. SS316 AODD Pump are unique for all Chemical and any Viscosity. SS AODD Pump has no comparison for Continues operation, as it can be run 24 Hours a Day and 7 Days a Week. AODD Pumps are relatively low cost and reliable; they can be run dry and can pump dirty/contaminated liquids.
The Air Operated Diaphragm Pump (AODD Pump) is a positive displacement pump. It comprises two pumping chambers that are alternately filled and released by flexible diaphragms moving back and forth. To provide the pumping motion, compressed air is alternately delivered to and vented from air chambers on opposing sides of the diaphragms. Sludges, slurries, abrasive, and shear sensitive fluids may all be handled by Air Operated Diaphragm Pumps, which are commonly employed for transfer applications. They are durable, dependable, and simple to operate, but they are loud, prone to icing, and only suitable for low-pressure applications. When many viscosity chemicals must be handled by the same AODD Pump, Air Operated Diaphragm Pump is employed.
The alternating and repetitive back-and-forth movement (strokes) of two flexible membranes or diaphragms positioned on a shared shaft move fluid in an Air Operated Diaphragm Pump. Although Diaphragm Pumps may be directly operated by connecting the shaft to a motor, an AODD Pump employs compressed air and a complex distribution system that alternately directs the air to two air chambers A and B on opposite sides of the diaphragms.
Air is sent to air chamber A by the compressed air control system.
The shaft travels to the left, and the diaphragms move to the right, increasing the volume of pumping chamber B while decreasing the volume of pumping chamber A. Fluid passage through the pump is only allowed in one direction: from intake to discharge, thanks to valves on each side of the pumping chambers. The result is that fluid is drawn into chamber B from the intake and discharged from chamber A.
The air distribution system vents air chamber A and sends compressed air to air chamber B when the shaft completes its stroke.
The shaft now advances to the right, lowering the capacity of pumping chamber B while simultaneously increasing pumping chamber A. The fluid in chamber B is now released and pulled into chamber A.
The air distribution system vents air chamber B when the shaft completes its stroke, and the cycle begins again when compressed air is delivered to air chamber A.
