An Air-Operated Double-Diaphragm pump (AODD) Is a Sort of Positive displacement (PD) pump. ) It is made of just two pumping chambers which are alternately filled and discharged from the motion of flexible diaphragms. Compressed air is fed to and vented out of, air chambers on the other faces of the diaphragms to make the pumping activity. AODD pumps Are Usually used for transport applications and can handle a large array of feeds such as sludges, slurries, abrasive and shear sensitive fluids. Though they are strong, dependable and simple to keep them may be noisy, susceptible to icing, and therefore are confined to non-pressure applications. AODD pumps are basically leak-free. There are just static seals between the wetted components and the exterior environment so leakage may only happen if both diaphragms neglect. As part of an overall care program, diaphragms must be replaced frequently, according to the Aodd pump Manufacturers   guidelines. Diaphragms have les...

What is a positive displacement pump? A positive displacement pump moves fluid by repeatedly enclosing a fixed volume & moving it mechanically through the system. The pumping action is cyclic & can be driven by pistons, screws, gears, rollers, diaphragms or vanes. How does a positive displacement pump works? Although there are a wide variety of pump designs, the majority can be placed into two different categories:  reciprocating  &  rotary . Reciprocating positive displacement pumps A Reciprocating Positive Displacement pump works by the repeated back & forth movement of a piston, plunger or diaphragm. These cycles areas also called as  reciprocation . In a piston pump, the first stroke of the piston creates a vacuum, opens an inlet valve, closes the outlet valve & draws fluid into the piston chamber (the  suction  phase). As the motion of the piston reverses, the inlet valve, now under pressure, is closed ...

There are various types of positive displacement pump in the market and they are often classified according to the mechanism used to move the fluid. For example; Rotary Pumps Positive Displacement These incorporate apparatus, screw, vane, peristaltic, flap, and dynamic hole and they all utilization pivoting parts to move the fluid into and out of the pump chamber. Some rotational pumps, for example, outfit pumps, must have tight freedom between the pivoting components and the dividers of the chamber, and between the turning parts, which implies they by and large can't be utilized to pump huge solids or grating liquids that may wear the parts. Different sorts, for example, flap pumps and dynamic pit pumps are intended to move fluids containing solids. Reciprocating Pumps Positive Displacement Counting plunger, diaphragm pump , cylinder, pressure driven, and numerous others - utilize a dull responding instrument to grow and get the chamber at standard interims. Respo...

·       Peristaltic Pump: A peristaltic pump is a sort of positive relocation pump utilized for pumping an assortment of liquids, they are likewise regularly known as roller pumps. The liquid is contained inside an adaptable cylinder fitted inside a round pump packaging (however straight peristaltic pumps have been made). A  rotor with a number of "rollers", "shoes", "wipers", or "lobes" attached to the external circumference of the rotor compresses the flexible tube. As the rotor turns, the part of the tube under compression is pinched closed (or "occludes") thus forcing the fluid to be pumped to move through the tube. Additionally, as the tube opens to its natural state after the passing of the cam ("restitution" or "resilience") fluid flow is induced to the pump. This process is called peristalsis and is used in many biological systems such as the gastrointestinal tract. Ordinarily, there will be at ...

4 Reasons to use AODD 1) The Importance of Air As their name states, the operation of AODD pump relies on compressed air, which can be found in most chemical-processing plants around the world. Leveraging this ready availability of air can make the AODD pump a true plug-and-play device that requires no infrastructure upgrades to incorporate. 2) Low Maintenance Costs Through Proper Diaphragm Selection Diaphragm pumps have a unique benefit when compared to many rotating-pump technologies in that they don’t require any seals. Elimination of the need for packing or expensive mechanical seals means that maintenance costs tend to be inexpensive and infrequent. Combined with the ease of operation, AODDs are a true “set-and-forget” type of pump, provided the right diaphragms are selected for the application. 3) Versatile and Compatible By definition, chemical processing requires the completion of some of the most intricate and complex industrial operations in the worl...
