air operated

Air operated double diaphragm pumps in GA are versatile workhorses that can be used for a huge range of fluids. They are used in facilities of all sizes, and in a variety of different industries. From petrochemical to food and beverage, these pumps are popular and versatile. Their unique design is ideal for transferring highly abrasive or sticky products. But how do they work?

The Working Principle of an Air Operated Double Diaphragm Pump in GA

A double diaphragm is a positive displacement pump, which utilizes two flexible diaphragms that reciprocate back and forth, creating a temporary chamber that both draws in and expels fluid through the pump. The diaphragms work as a separation wall between the air and the liquid.
The two diaphragms are connected by a shaft through the center section, where the air valve is located. The purpose of the air valve is to direct the compressed air to the back of diaphragm number one causing it to move away from the center section.
The number one diaphragm moves liquid out of the pump, while at the same time diaphragm number two is performing suction. The air behind diaphragm number two is being pushed out to the atmosphere, causing pressure to push the liquid to the suction side. The suction ball valve is pushed off its seat allowing the fluid to flow past the ball valve into the liquid chamber.
When the pressurized diaphragm number one has reached the end of its stroke, the movement of the air is switched from diaphragm number one to the back of diaphragm number two by the air valve. The compressed air pushes diaphragm number two away from the center block, resulting in diaphragm number one being pulled toward the center block.
In pump chamber number two, the discharge ball valve is pushed off its seat, while in the pump chamber number, one the opposite occurs. Upon completion of the stroke, the air valve leads the air to the back of diaphragm number one and restarts the cycle.

Where Can Air Operated Double Diaphragm Pumps in GA Be Used?

Diaphragm pumps are a common sight in many industries. There is an extensive number of construction materials available to produce a number of configurations to accommodate difficult fluids such as:
 Corrosive chemical;
 Volatile solvents; 
 Viscous, sticky fluids;
 Shear-sensitive foodstuffs and pharmaceutical products;
 Dirty water and abrasive slurry;
 Smaller solids;
 Creams, gels, and oils.

Why choose air operated double diaphragm pumps in GA?

As long as there is a compressed air supply available, the pump can be installed wherever it is required. And should circumstances change, it can be moved and switched to other operations with ease.
Whether the fluid being handled requires a gentle pumping action or is chemically or physically aggressive, the positive displacement AODD pump offers an efficient and low maintenance solution.
