In many situations, ARO Air-Operated Diaphragm Pumps in GA can be a more dependable option than centrifugal pumps. While a centrifugal pump design is uncomplicated, with easy-to-understand pumping principles, they are one of the most difficult industrial pumps to choose for an application.
There are many setup and design variables that must be properly identified so a centrifugal pump can work as intended. If the pump and process are set up correctly, the pump works very well. But even small alterations to process conditions, such as pressure, fluid viscosity, particle level or flow, can dramatically reduce the reliability and efficiency of the centrifugal pump.
Centrifugal pumps are also often a source of chronic reliability and maintenance issues. They are designed to function near a Best Efficiency Point (BEP) or single operating point. Transferring process conditions even 10 percent from this point can dramatically lower the efficiency and cut the reliability in half.
Why Choose ARO Air-Operated Diaphragm Pumps in GA?
ARO Air-Operated Diaphragm Pumps in GA are easier to specify for an application and can run consistently and dependably across the entire operating range, not just a single point. They can substantially reduce the possibility of cavitation during operation. They also have a wide operating window that allows the customer to make alterations in their process without having to change the pump.
Advantages of ARO Air-Operated Diaphragm Pumps in GA
These pumps have several advantages that can solve many common centrifugal pump issues, including:
- Deadheading without energy use or damage;
- Self-priming;
- Greater flow control;
- Wide reliable pressure and flow operating range;
- More broad viscosity range and/or chemical compatibility;
- Smaller size, weight, and footprint;
- Lower investment needed.Â
Centrifugal Pump Problems and AODD Solutions
If any of the conditions or applications outlined below are part of your process, you should probably consider an AODD pump.
These are five common issues or applications where ARO Air-Operated Diaphragm Pumps in GA could be a better answer.
- Suction Lift Applications: Standard centrifugal pumps don’t create a vacuum and cannot generate a suction lift. Diaphragm pumps are the common-sense choice when a suction lift is needed.
- Shear-Sensitive Liquids: Pumps typically shear liquids more as speed is increased. This makes an AODD pump a better option to handle liquids that are shear-sensitive. Diaphragm pumps function at lower speeds, are gentle on products and are preferred in these applications.
- Metering: ARO Air-Operated Diaphragm Pumps in GA are an ideal choice for metering applications because they provide constant flow, which allows them to meet process requirements easily.
- Stall Capability: When pumping pressure increases in an application, an AODD pump will cease pumping. On the other hand, a centrifugal pump will continue to build pressure until something fails and the pump is severely damaged. Some liquids fluctuate in viscosity due to chemical or temperature reaction, making AODD pumps the right choice for applications with these fluctuations.
- Variations in Flow: Centrifugal pumps don’t tend to operate well when running too far off the middle of the curve. If a higher or lower flow is required, efficiency is reduced and this can cause, shaft deflection, premature pump failure, and cavitation damage. An AODD pump is well suited for flow variations.
