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.
Antlia Engineering Works is one of the leading manufactures
peristaltic pump and AODD pumps in Australia,
middle east, Africa & India. One can choose pumps that best suits their
needs.
