About AODD Pump – 3 Industrial Uses and Applications



AODD pumps (also known as Air operated diaphragms pumps, pneumatic diaphragm pumps, AODD pumps, AOD pumps) are used for endless applications in mining, industrial and general plant service. Powered only by compressed air, they are especially used where electricity isn’t available, or in explosive or flammable areas.

AOD pumps are a type of reciprocating diaphragm pump which contains two diaphragms driven by compressed air. Air section with shuttle valve applies air alternately to the two diaphragms, each diaphragm has a set of check/ball valves.

Chemical & Refineries:

AODD Pump can handle all types of chemicals including acids, bases, solvents and alkalis, resins and adhesives, high-density liquids and viscous products even with the presence of solid parts and particles. Moreover, they can also transfer oil skimming, oil sludge, storm water, seawater, drainage water, latex, corrosion inhibitors, fertiliser, pesticides, insecticides and more.

The AODD Pump finds application in pumping of raw materials and derivatives, storm water drainage, unload trucks, sump and tanks drainage, empty the cistern and to be used in waste water treatment, desalination plants, scrubber’s application, distillation plant and filters press.

One of the less obvious reasons that AODD pumps are selected is the range of chemicals that can be transferred, injected, batched or filled during a process or application. There are hundreds, if not thousands, of configurations for AODD pumps to handle almost any chemical. A typical AODD original equipment manufacturer (OEM) might have as many as 1,700 viable configurations based on size, wetted material, elastomeric options, center body and hardware materials.

Waste Water Treatment:

In the water treatment industry, diaphragm pumps are used in industrial and municipal wastewater treatment plants. Some fluids that are put into the pumps from wastewater treatment plants are high in viscosity and require pumps that can handle those liquids. Air operated double diaphragm pumps also help to pump polymers, acids, caustics and slurries during the water treatment process that are used to treat water.

Food & Beverages:

Air operated double diaphragm pump are used in the food and beverage industry for various food processing application. This pumps can be used for transferring food products like tomato pulp, chocolate, soft drinks, ham pulp, vinegar, pet food, yeast, eggs, vegetable oil, honey, vitamins, glucose syrup, concentrates, decaffeination, wine, fruit pulp, fruit juice, rennet, aromas and more.

Moreover, diaphragm pumps can be used also for pumping chemicals like caustic soda, nitric acid, hydrochloric acid, antioxidants and brine and waste products like animal blood, waste water and sludge. They find application in the food processing, CIP (cleaning in place) plants, and waste water treatment and slaughtering.

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...
