How does air operated Diaphragm Pump works?
Air Operated Diaphragm pump or AODD Pump is a positive displacement pump that uses a combination of the reciprocating action of rubber and balls. Rubber, Thermoplastic or Teflon Diaphragm and suitable Diaphragm used in AODD Pumps. It is made up of two pumping chambers that are filled and discharged alternately by the movement of flexible diaphragms. To generate the pumping action, compressed air is alternately fed into and vented from air chambers on opposite sides of the diaphragms. When the Diaphragm of a Diaphragm Pump moves up the volume of a chamber of either type of pump pressure increases, the pressure decreases, and fluid is drawn into the chamber. When the chamber pressure later increases from decreased volume the diaphragm moves down, the fluid previously drawn in is forced out of the chamber of a Diaphragm Pump. Finally, the diaphragm moving up once again draws fluid into the chamber, completing the cycle. This action is similar to that of the cylinder in an internal combustion engine.
There are a very few Diaphragm Pump Manufacturers in India we are one amoung them. Air Operated Diaphragm Pumps are commonly used in transfer applications and can handle a wide range of feeds such as sludge, slurries, abrasive, and shear sensitive fluids. They are robust, reliable, and simple to maintain, but they are noisy, prone to icing, and limited to low-pressure applications. The most common type of pump used in the chemical industry is the Air Operated Double Diaphragm Pump (AODD), also known as the Pneumatic Operated Diaphragm Pump. Positive displacement pumps, often known as AODD pumps or pneumatic pumps, are a form of AODD pumps. Air Operated Diaphragm Pumps are powered by compressed air rather than electricity, allowing them to safely transfer and pump potentially hazardous, flammable, or corrosive fluids. Air Operated Diaphragm Pumps have two chambers, each with its intake check valve, output check valve, and diaphragm, which is why they’re also called double diaphragm pumps. The air supply is switched from one chamber to the other by moving back and forth. Fluid is driven out when the diaphragm returns to the opposite chamber, and the other chamber begins to fill. The fluid is ejected out when the diaphragm moves back into the opposite chamber. The pumping action is created by this motion.
