Advancements in efficiency and a good array of chemicals combine to form the air-operated double-diaphragm (AODD) pump a useful choice for chemical processors. The circumstances surrounding the event of the air-operated double-diaphragm (AODD) pumping principle six decades ago involved a ruptured hookah, a flooded workshop and an exclamation that the thought could “make 1,000,000 dollars.” within the ensuing 60-plus years, those words have proven to be prophetic, because the AODD pump technology that was said to be “conceived out necessarily, born within the arms of innovation, and inspired by sheer will and determination” has become a frequent choice for operators in heavy-duty industries that need the pumping of water, slurries or any finely divided substance, like cement. AODD pumps (Figure 1) can obtain dry self-prime, run dry, maintain suction lift up to 30 ft, withstand deadhead pumping conditions, operate while completely submerged and pass solids of up to three in. in diame...

  Diaphragm pumps have very significant properties, which make them particularly suitable to be used in agriculture on spraying bars and air-blast sprayers. The three main advantages of a diaphragm pump compared to a pump are: 1. Excellent head and self-priming capacity. 2. Good dry running capacity 3. Resistance to abrasion and corrosion The diaphragm pump working which uses alternating variations within the volume of a chamber (expansion and contraction) to get imbalances in pressure between the chamber and adjacent spaces. Trying to catch up on the difference in pressure between two environments, the fluid naturally moves from the space with greater the pressure to space with lower pressure, leading to a downward movement, a rise, and briefly within the pumping of the fluid itself. The expansion and contraction of the chamber volume that generate these pressure changes are obtained by means of the alternating flexing of the diaphragm. The diaphragm is nothing quit...
