What is an Air Operated Double Diaphragm (AODD) pump?

An AODD pump is a positive displacement pump that uses compressed air to move fluids using two diaphragms in a reciprocating motion.

What fluids can AODD pumps handle?

They can handle viscous, abrasive, corrosive, and solid-laden fluids across multiple industrial applications.

Do AODD pumps require electricity?

No, they operate using compressed air, making them ideal for hazardous environments.

How is flow controlled in AODD pumps?

Flow rate is controlled by adjusting air pressure and air supply to the pump.

Are AODD pumps easy to maintain?

Yes, they have a simple design with minimal components, making maintenance quick and cost-effective.

Air-Operated Double Diaphragm Pump Applications:-

To handle viscous chemicals and slurries.
To transfer explosive liquids, solvents, and acids.
Pharmaceutical liquids, creams, and compounds.
Semi-solid foods, flavors, drinks, wine, beer, and alcohols.
Wastewater, sewage effluents, coal, and lime slurry.
Hydrocarbons, petrol, diesel, lubrication oil, vegetable oil.
Paints, emulsions, pigments, thinners, and resins.
Ceramics, slip, glazes, clays.

Advantages of AODD Pumps: -

No Seal, No Leakage,
Self-priming, no need for a foot valve,
Variable flow with the same pump.
Can be submerged.
Less stock of spare parts to be maintained.
No skilled person is needed to operate and repair the pump.
Lightweight and handy in use.
No rotation, no wear & tear, hence low maintenance, no charging.
The pump can run dry.
Stop the automatic closing of the discharge valve.
Can handle 2 to 10 mm-sized solid particles.
Also can be used up to an accuracy of 3 to 5%
No motor, no fire.
In short, a very simple and versatile pump.

Operation Principle:-

Dry air is given as input to the air valve. Air will push both diaphragms alternately.
Four ball valves will act as NRVs for suction and delivery.
As per the liquid compatibility MOC of the diaphragm, valve, and wetted part selected.
