EODD PUMPS VS AODD PUMPS: DIFFERENT OR SIMILAR?

In a modern setting compared to the past, diaphragm pumps are evolved in the ability to function based on different power sources to be more considerate towards the environment. The two key players in this setting are the Electric Operated Double Diaphragm (EODD Pump) and the Air Operated Double Diaphragm (AODD Pump). These two pumps are considerably the most sought-after upgrade in the industrial sector. Through this article, we will be exploring the features, advantages and applications of the pumps in industrial settings to assist in making a better-informed decision for your specific requirements.

The Power Source 

The two different pumps run off on different sources of energy which would be the main consideration when making a choice to choose a pump better suited for the environment that surrounds the requirements of the pump. An EODD Pump runs on electricity to run the diaphragm motors and constant electricity power to ensure the pump’s continuous operation. Meanwhile, the AODD Pump runs on air operation and relies on the diaphragm’s flexibility which causes movements that move the fluids to the required position. While both have different power sources, they run differently as well as focusing on different abrasive materials as well as different controls and adaptability by the user’s requirements.

Operational Benefits

The operational benefits of both pumps are varied based on the requirements of the project or purpose of the pumps. There is a difference between the functionality of the pumps in its process and control. The EODD Pump allows the user to control the diaphragm in setting the flow rates of the pumped fluids, the motorized diaphragms allow for a precise control over the operation. On top of that, the pumps come in a more complex form, the EODD Pump would have an integrated surge suppression which is the ability to stall against back pressure. Using the EODD Pump technology may be worthwhile due to its small size and its potential to replace multiple pumps down the line of operation.

Now moving on the AODD Pump, it contains two pumping chambers that are filled and discharged alternatively by the movements of the flexible diaphragms. The AODD Pumps are essentially leak-free as the stationary seals are placed between the wetted parts and the outside environment which will only cause leakage if one or both of the diaphragms were to fail. Due to the pump not containing any internal seals or moving components that require lubrication and cooling, an AODD Pump would be able to run dry indefinitely without damage. These factors are suitable for requirements that places themselves in hazardous areas due to the usage of air which lowers potential harm to the surroundings.

By understanding its operational benefits, a user can make a more informed decision on the pump requirements of their own beneficial uses.

Portability & Flexibility 

The EODD Pumps are more stagnant in moving as it dependent on an electrical power source, which may limit their portability making them more suitable for applications with a fixed power source available close to it. Meanwhile, the AODD Pumps are more portable and versatile as they can be installed without needing a specific power source or are stagnant in the process of movability which makes them the ideal choice for remote or challenging environments.

Safety Considerations 

As the EODD Pump runs on electricity there are more concerns regarding its safety especially based on its power source due to the potential safety hazards which would require extra safety measures, however the EODD Pumps do come with explosion proof design and systems. Compared to that, the AODD Pump runs on compressed air which is more of a cautionary choice due to the lack of potential safety hazard to the people surrounding the environment.

Energy Efficiency 

Comparing the two pumps’ based on its energy efficiency the EODD Pump is electrically driven which makes it more energy efficient especially if the pump is installed in an application with a consistent power supply running through it. Meanwhile, the AODD Pump depends on the availability and the cost of compressed air would make it less energy-efficient compared to a pump with a connected source of energy.

While the debate is heated between these two pumps, there is no possibility that one pump fits all. The choice of which pump to choose is based on the specific requirements of the application, the industry regulations and the availability of power sources based on the choices made. The two pumps shine differently based on its surroundings and uses. The EODD Pumps are one of the best options when choosing for precision and control, especially when the power source is constant while the AODD Pump shines the most when the requirements are portability, safety and versatility, especially when the location is remote or hazardous. At the end of the day, the choice on which pump would be better depends on the unique application of the pump and which focus would the user want on their application.
