No Electricity: These pumps operate via compressed air. This means that they can be used in environments where an electrical supply is not suitable i.e. in hazardous areas.
Simplicity: Without requiring complicated wiring, and no need to have an electrical control, AODDs are easy to install and operate. In fact, they are much easier to use than many other pump types.
Run Dry: AODD pumps can run dry without damaging the pump or cause any issues. Some other pump types will always need to stay primed and not run dry or they will either damage the whole pump or some of the parts, resulting in a costly rebuild.
Viscous Liquids: Air operated double diaphragm pumps can handle a variety of fluid viscosities. Having a pump which can transport both high and low viscous materials means that a pump can be used for a variety of tasks. Some other pump types cannot handle highly viscous fluids and will stop working or breakdown under the same conditions.
Abrasive Materials
Just as with handling low and high viscosities, an AODD pumps can also process corrosive or abrasive fluids, as well as more solid or powdered materials.
Gentle pumping
These diaphragm pumps have no impellers or other moving parts exposed to the liquid being pumped, which means that they are suited for transporting shear sensitive media.
Safety
All of the above combined, also means that an AODD pumps is a great option when pumping volatile or dangerous liquids.
Application of Air Diaphgram
Water Treatment
Diaphragm pumps are employed in waste water systems for pumping and transferring various types of waste, including sewage, sludge, and effluent. They can handle solids and semi-solids, making them suitable for such applications.
Chemical Industry
Diaphragm pumps are extensively used in the chemical industry for handling and transferring chemicals, acids, solvents, and other aggressive substances. Their ability to resist corrosion makes them suitable for such applications.
Pharmaceutical Industry
Accurate fluid transfer is important in pharmaceutical production. Diaphragm pumps contribute to the safe and precise transfer of solvents, acids, bases and other pharmaceutical ingredients. They are used in all stages of pharmaceutical production and formulation.
Food And Beverage
They are typically used to pump liquids such as juices, sauces, dairy products and liquid ingredients, while maintaining hygiene and avoiding contamination.
Mining And Construction
Diaphragm pumps are used in mining and construction sites for dewatering excavations, pumping mud and slurry, and pumping abrasive materials such as sludge and silt.
Components of Air Diaphgram
Manifolds
Manifolds are pipes that connect numerous pumping units to provide a single suction and delivery line, simplifying installation.
Fittings
Fittings Both manifolds have a straight or curved hose tail that connects the pump to the machine circuit.
Safety Valve
A safety (or pressure relief) valve is designed to mitigate the effects of overpressure on the supply line.
PTO Guards
PTO guards protect operators and others from rotational components that provide a significant safety risk.
Oil Compensator
The oil compensator is a transparent receptacle filled with lubricating oil and attached to the crankcase's oil bath. The oil compensator is used to ensure that the oil level is correct and, if necessary, refill it.
Pressure Accumulator (Or Pulsation Dampener)
The pressure accumulator is used to lessen or eliminate pulsations, prevent potential pipe pounding, lower the burden on the pump, and reduce noise; as a result, pumps will wear less and last longer.
