Exploring the Maximum Capacity of Air-Operated Double Diaphragm Pumps

 

Understanding Air-Operated Double Diaphragm (AODD) Pumps

AODD pumps use compressed air to move fluids efficiently. They are versatile and reliable. These pumps handle everything from water to abrasive and viscous fluids. Their air distribution system ensures consistent performance.

  • Self-priming capability allows easy startup and operation.
  • Handles various fluid types, including corrosive and high-viscosity liquids.
  • Can run dry without damage, increasing reliability.

 

What is the principle of AODD pump?

AODD pumps operate using two diaphragms that move back and forth, driven by compressed air.

This motion creates suction and discharge, allowing fluid transfer. Flexible diaphragms separate the fluid from the air side. Check valves control the flow direction, ensuring efficiency. The air valve system regulates the compressed air supply, optimizing performance and reducing air consumption in high-performance applications.

ARO’s EXP Series pumps feature advanced air valve systems that maximize efficiency in positive displacement applications.

 

How to Choose an AODD Pump?

Selecting the right AODD pump depends on the following factors:

  • Flow rate requirements and discharge pressure conditions
  • Material compatibility with the fluid being transferred
  • Solid-handling ability and operating environment

How to Calculate Pump Flow Rate?

The flow rate can be calculated using the formula:
Flow rate (gpm) = Stroke volume x Strokes per minute.
By measuring the volume per stroke and adjusting the stroke rate, the flow rate is accurately determined. The compressed air supply controls the pump’s speed and efficiency.

 

How to Calculate Pump Capacity?

Pump capacity is influenced by the pump size, air pressure, and operating conditions. Manufacturer specifications provide precise values for capacity. Adjusting the compressed air supply optimizes performance. ARO diaphragm pumps offer flexible flow adjustments ranging from 1 l/min to 1,079 l/min (285 gpm), making them suitable for a wide range of industrial applications.

 

Can Diaphragm Pumps Run Continuously?

Yes, diaphragm pumps can run continuously, but proper maintenance is essential.

Preventing overheating and diaphragm wear is key to ensuring long-term operation. Regular inspections prevent diaphragm damage, and monitoring the compressed air supply improves efficiency. Proper installation also helps reduce unnecessary wear.

ARO’s Pro-Series pumps are designed for stall-free continuous operation, ideal for demanding applications in industries such as chemical processing and wastewater treatment.

 

What Is the Capacity of a 3-Inch AODD Pump?

A typical 3-inch AODD pump has a maximum flow rate of 230-260 gpm (870-984 l/min), depending on the air supply and operating conditions.

ARO’s EXP 3” diaphragm pumps are capable of flow rates up to 1,079 l/min (285 gpm), providing superior durability for bulk fluid transfer and high-demand industries.

 

How Many GPM/liters and PSI/bar Is a Diaphragm Pump?

ARO’s air operated diaphragm pumps support a wide range of fluid pressures and flow rates, ensuring optimal performance for different applications.

 

What Is the Normal Pump Capacity?

Pump capacity varies depending on the application and pump size. Small pumps typically handle flow rates between 10-100 gpm (37-378 l/min), while larger pumps can exceed 1,000 gpm (3,785+ l/min). AODD pumps offer flexible flow rates, which are determined by air consumption.

Applications that require high-volume fluid transfer benefit from ARO’s EXP Series, providing process-grade performance with flow rates up to 1,079 l/min (285 gpm).

 

Flow Rate of a 1.5-Inch (1-1/2") AODD Pump?

A typical 1.5-inch diaphragm pump delivers 340-400 gpm (1,287-1,514 l/min), depending on air pressure and fluid type. ARO’s Pro-Series 1.5” pumps ensure high efficiency and reliability for industrial and process applications.

 

How to Calculate Pump Strokes per Minute?

The strokes per minute (SPM) can be calculated with the formula:
SPM = Flow rate / Stroke volume.
By measuring the fluid moved per stroke and adjusting the air supply, flow can be accurately controlled. AODD pumps use an air valve system to regulate performance, and ARO pumps allow precise regulation with air filters and needle valves, ensuring optimal performance and cost-effective operation.

 

What Is the Maximum Flow Rate of an AODD Pump?

Large AODD pumps can exceed 1,000 gpm (3,785 l/min). Factors such as air pressure, diaphragm size, and compressed air supply control the pump’s output. Regular maintenance ensures consistent performance.
