Air Operated Double Diaphragm Pump AODD, in English Air Operated Double Diaphragm Pump , are alternative double diaphragm volumetric pumps, which use compressed air as the motor fluid. COMPONENTS Three main sections can be recognized in the construction of an AODD pump: CENTRAL BODY : includes the entry and discharge of the supply air and the pneumatic exchanger. FLUID CHAMBERS : they house the volumes in which the fluid is aspirated and pumped, including the membranes (green and yellow in the image below). Sometimes they include the housing of the balls (with a function similar to that of the valve with no return in and out). COLLECTOR : offer the system connection interface. Sometimes they include the housing of the balls (with a function similar to that of the inlet and outlet check valve). Depending on the size of the pump and the series to which it belongs, the various components may have different arrangements even if the principle of operation is the same. FUNC...

Since its invention in 1955 as a mining pump, Wilden's air-operated double diaphragm pneumatic pump (AODD) and distributed by Fluid Technique, has earned a huge reputation as the ideal technology for utilitarian, auxiliary or basic handling applications and liquid transfer AODD pumps stand out in this type of applications because they have design features that allow them to offer a simple operation, without mechanical seals, possibility of self-priming, dry function, achieve a suction lift of up to 9 meters, resist head pumping conditions dead, operate while submerged and pass solids up to 76 mm in diameter. Companies did not take long to realize the advantages of these operational features in many process applications and why AODD pumps are true “process” pumps capable of operating efficiently, reliably and safely in a wide range of applications. critics. AODD pumps also reach the optimum point of operation in many of the fluid handling tasks that prevail in the chemical pro...

In any giant installation of air-operated double-diaphragm (AODD) pumps, a comparatively tiny portion of pumps contribute to more than average maintenance prices, usually because of misapplication. Since the bulk of AODD pump applications involve no over easy method fluid transfer, several pumps are mobile and transferred from one location to a different. An operator could attribute a “good” pump installation to the pump, and not the installation. The operator could transfer the “good” pump to a brand new installation and shortly once, the “good” pump becomes a major maintenance downside. Worse still, the high maintenance could become routine, leading to substantial prices, in relation to the pump. Since most AODD pump applications ar either easy transfer or filter press feed, following a number of necessary steps will avoid pricey mistakes. 1. Piping System properties, like piping, will contribute considerably to AODD pump application problems, particularly on the suct...
