What is the Maximum Capacity of AODD Pump?

Air-operated double-diaphragm (AODD) pumps are well known for their versatility and dependable performance in various applications. They are capable of handling anything from slurries to shear-sensitive fluids, making them a popular choice in industrial environments. However, one important question that often arises is: What is the maximum capacity of an AODD pump?
This article takes a dive into the world of AODD pumps, examining the factors that impact their pumping capacity and showcasing the strengths of industry leaders such as IDEX FMT and Sandpiper.

Understanding AODD Pump Capacity

Unlike pumps that use impellers, AODD pumps employ diaphragms to draw in fluids. By using air to push the diaphragms, a chamber is created that fills with liquid. When the air pressure changes direction, the diaphragms push the liquid out of the pump. This back-and-forth motion enables AODDs to handle liquids, solids, and even air pockets.

The maximum capacity of an AODD pump is influenced by two factors:

·       Flow Rate: This metric, typically measured in litres per minute (LPM) or gallons per minute (GPM), indicates how much liquid volume the pump can transfer within a specific timeframe.

·       Discharge pressure: Discharge pressure, measured in pounds per inch (PSI), or bar discharge pressure, indicates the force the pump can apply to propel the liquid through the discharge line.

There's a balance between flow rate and discharge pressure when it comes to AODD pumps. Typically, increasing flow rate results in a reduction in discharge pressure, and vice versa. 

IDEX Sandpiper AODD Pumps

Sandpiper pumps are known for their user-friendly design, efficient performance, and compatibility with fluids. The range includes pumps with varying capacities:

The AccuPrime Series, equipped with a patented air valve design, can deliver flow rates of up to 833 litres per minute (220 gallons per minute) and discharge pressures of 10.3 bar (150 pounds per square inch).

The Standard Duty Series offers flow rates of up to 568 liters per minute (150 gallons per minute). Discharge pressures up to 7.6 bar (110 pounds per inch) making it suitable for a wide range of applications.

Choosing the AODD Pump beyond Maximum Capacities

Selecting the right AODD pump involves more than just considering high flow rates or discharge pressures. Factors, like the viscosity of the liquid and the presence of solids should also be taken into account when choosing the pump model.

Choosing the materials, for the pump is crucial to prevent any damage from the liquids it handles.

It's essential to consider how often the pump will be running to ensure it meets your needs.

By examining these factors along with the desired flow rate and discharge pressure, you can find the best AODD pump for your application that improves performance and efficiency.

Tips for Maximising AODD Pump Efficiency

1.      Optimising Air Supply

AODD pumps operate on air. Here are some ways to make sure you're using air efficiently:

·       Maintain the correct air pressure: Make sure the air pressure aligns with what is recommended for the pump. Using too much energy can harm the pump, while too little pressure reduces performance.

·       Reduce Air Line Length and Obstructions: Long or twisted air lines can lead to drops in pressure. Opt for lines with bends and proper diameters to maintain optimal air pressure at the pump.

·       Consider using Air Saver Kits: These kits, designed for AODD pump models, help save energy by utilising an air chamber for diaphragm actuation. This leads to reductions in air consumption.

2.      Choosing the Right Diaphragm Material

Diaphragms serve as the core component of an AODD pump, and the material you choose greatly influences its performance and longevity. Here's a breakdown of used diaphragm materials:

·       Santoprene: These are known for its flexibility and resistance to wear and tear.

·       Nitrile Rubber: A cost-effective option suitable for liquids but may degrade when exposed to chemicals or high temperatures.

·       PTFE (Teflon): These offer excellent chemical resistance and low friction, making it ideal for harsh chemicals and shear sensitive fluids. However it may not be as durable as other options.

·       Buna N: Suitable for handling oils and fuels but not recommended for high temperature applications.

By understanding the characteristics of these materials and selecting one based on the liquid being pumped, you can ensure optimal diaphragm performance. Pump longevity.

3.      Maintenance

Proper maintenance is essential to extending the life of your AODD pump while maximising its efficiency.

Here are a few important maintenance tips:

·       Follow the maintenance schedule recommended by the manufacturer, which typically includes inspections, cleaning, and lubrication.

·       Regularly check the diaphragms, for any signs of wear or damage. Replace them promptly to avoid leaks and maintain pump efficiency.

·       Make sure to change the air filters on a regular basis, as clogged filters can reduce air flow and affect pump efficiency.

·       Choose a pump size that matches your application’s needs to avoid inefficiencies or potential damage. Calculate the required flow rate and discharge pressure carefully before selecting a pump.

·       Consider using pumps with features like speed drives for precise control, automatic shut off systems for energy savings when not in use, and heated diaphragms for better performance, with cold or viscous liquids.

By following these strategies to optimise your AODD pump, you can ensure it operates at its best, extending its lifespan, lowering energy usage, and cutting down on expenses.

Conclusion

AODD pumps offer a mix of flexibility and pumping strength. While IDEX FMT and IDEX Sandpiper pumps are known for their capacities, understanding how flow rate, discharge pressure, and specific application needs interact is crucial to choosing the right pump. Seeking advice from a pump specialist can help you make the most of AODD technology for fluid handling in your industrial processes.

To wrap up, knowing the capacity of AODD pumps is one aspect. Apart from that, enhancing air supply efficiency, selecting the diaphragm material, following maintenance practices, sizing the pump correctly, and exploring advanced features are all vital to boosting the effectiveness and performance of your AODD pump. By taking this approach, you can unlock the potential of AODD technology for dependable and effective fluid management in your industrial settings.
