One variety of PD pump is the Air Operated Diaphragm Pump. It uses the movement of flexible diaphragms to fill and empty two pumping chambers. Compressed air is pumped through the system by being put into and then released from chambers on either side of the diaphragms.
Transfer applications are the most common usage for these pumps and the vast range of feeds they can process means they aren’t limited to just sludges and slurries or abrasive or shear-sensitive fluids. They are sturdy, dependable, and simple to keep up with, but they make a lot of noise, are quickly iced up, and can only be used in low-pressure situations.
In what way does an AODD pump operate?
An Air Operated Diaphragm Pump displaces fluid through the reciprocating motion (strokes) of two flexible membranes or diaphragms connected to a central shaft. Directly driven diaphragm pumps have the shaft attached to an electric motor. In contrast, these pumps employ compressed air and a complex distribution system to alternately route the air to two air chambers on opposing diaphragms. When the shaft reaches its end position, air chamber B is vented by the air distribution system, and the process begins again when the compressed air is sent to air chamber A.
What are its primary advantages?
When it comes to leaking, these pumps are typically flawless. A leak can only occur if the diaphragm fails because all the other seals between the wetted portions and the outside environment are in place.
Diaphragm replacement is essential to any preventative maintenance plan and should be performed per the manufacturer’s guidelines. The pressure balance provided by the compressed air supply reduces the amount of wear experienced by the diaphragm in an Air Operated Pump compared to a manually driven diaphragm pump.
For pumping slurries, sludges, or sludge-like substances, these pumps supplied by Air Operated Diaphragm Pump supplier in India are up to the task. And because of the low shear pumping action, they are suitable for handling shear-sensitive fluids. Ball (or cone)/seat or flap designs are commonly used for the four internal check valves. Compared to flap designs, ball valves last longer and create a more reliable seal.
Eventually, the flexing point will wear out on flap-type valves due to their hinged design. To reduce uneven wear, ball valves allow the ball to spin during operation and rest in a different location on the seat. The advantage of flap-type check valves is that they enable larger particulates entrained within the pumped fluid to flow more easily.
