Air-Operated Double-Diaphragm – AODD pumps

AODD pumps is a variety of positive displacement pump which contains of two pumping compartments that are alternately filled and discharged by the movement of flexible diaphragms. Compressed air is interchangeably sent to, and vented from, air compartments on the differing sides of the diaphragms to generate the propelling action.
AODD pumps are usually used for transmitting applications and can manage a wide variety of inputs that includes sludge’s, slurries, rough and shear delicate solutions. Even though they are robust, dependable and easy to maintain they can be loud, prone to frosting, and are restricted to low pressure applications.

How AODD Pumps Work?

LEFT STROKE


The air valve leads pressurized air to the posterior side of diaphragm A. The compressed air is applied straight to the fluid column divided by elastomeric diaphragms. The diaphragm acts as a parting membrane between the compressed air and fluid, balancing the weight and eliminating mechanical stress from the diaphragm. 
The compressed air moves the diaphragm away from the middle block of the pump. The opposite diaphragm is dragged in by the shaft attached to the pressurized diaphragm. Diaphragm B is on its suction thump; air behind the diaphragm has been forced out to the ether through the exhaust port of the pump.
The movement of diaphragm B toward the middle block of the pump creates a vacuum within compartment B. Atmospheric pressure forces liquid into the inlet multiple times forcing the inlet valve ball off its position. Fluid is free to transfer past the inlet valve ball and fill the fluid Compartment.

MID STROKE



When the pressurised diaphragm pump, diaphragm A, reaches the limit of its release stroke, the air valve transmits pressurised air to the posterior side of diaphragm B. The pressurised air forces diaphragm B away from the middle block while pulling diaphragm A to the middle block.
Diaphragm B is now on its ejection stroke. Diaphragm B forces the inlet valve ball onto its position due to the hydraulic forces developed in the fluid chamber and manifold of the AODD pump. These same hydraulic forces lift the release valve ball off its position, while the opposite discharge valve ball is forced onto its seat, forcing liquid to flow through the pump ejection. 
The movement of diaphragm A near the middle block of the pump generates a vacuum within fluid chamber A. Atmospheric pressure forces liquid into the inlet manifold of the AODD pump. The inlet valve ball is then forced off its position letting the liquid being pumped to fill the fluid compartment.

RIGHT STROKE



At close of the stroke, the air valve again transmits air to the back side of diaphragm A, which starts diaphragm B on its exhaust stroke. As the AODD pump reaches its original initial point, each diaphragm has gone through one exhaust and one ejection stroke.
This establishes one complete pumping cycle and the pump may take numerous cycles to totally prime depending on the conditions of the application.
Antlia Engineering Works is one of the leading manufacturers of AODD pumps in India, Middle-East, Australia, Africa  and produce pumps that robust, reliable, easy to maintain, and comparatively low cost. They tend to be all-purpose mainstay devices and are usually used for transmitting applications in a wide range of industries.

OPTIMIZING USAGE OF AIR IN AODD PUMPS

In the industrial areas, there are some important operational costs – whether in the chemical processing, food & beverage, oil & gas, pharmaceutical, or mining industries – are the ones incurred for the purchase, operation & maintenance of pumps used during different production & transfer. One hidden component from the operating-cost perspective is the electricity used by double diaphragm pump , as per a study done by the Hydraulic Institute, account for nearly 20 percent of the world’s electricity demand. Assuming 7 cents per kilowatt/hour that equates to approximately $294 billion to operate diaphragm pump. Therefore, energy consumption can make up close to 90 percent of the total life-cycle costs of owning & operating a pump. Approximately 30 to 50 % of the energy consumed by pump systems can be saved by using air operated double diaphragm pump. Considering all the usage estimates, simple calculation reveals that up to $147 billion of electricity costs ...

Double Diaphragm Pump

What’s a double diaphragm pump? An air worked double diaphragm pump (also known as a Double-Membrane pump, pneumatic diaphragm pump or air-worked diaphragm pump) is a positive displacement pump that utilizes a mix of the responding activity of an elastic, thermoplastic or Teflon/pate diaphragm and appropriate valves on either side of the diaphragm (check valve, butterfly valves, fold valves, or some other type of stop valves) to pump a fluid. Diaphragm Pumps also known as Air Operated Double Diaphragm Pump ( AODD pump ), is a sort of responding positive displacement pump in which fluid is pumped by a responding diaphragm, which is driven by a solenoid, mechanical drive, or fluid drive. Different forms are air worked Pump has inlet & outlet check values. Diaphragm pump has great dry running qualities; they can be up to 97% effective. Diaphragm Pumps can deal with exceedingly thick fluids. A double diaphragm pump is known as a positive displacement pump. It utilizes t...
