If you are a repair manager or process engineer, you may already know that pneumatic double barrier (AODD) pumps are very useful. Air driven double barrier pump (AODD) is a positive displacement pump which is different from other positive displacement pumps and is powered by compressed air or natural gas. Because the air pressure acts on the whole working surface of the barrier, the barrier is always in a state of pressure balance during the pumping process. Compared with the mechanical barrier pump, the service life of the barrier is significantly prolonged. on the other hand. Because of the limitation of compressed air. SANDPIPER The working pressure of the pump will also be controlled within the safe scale.

The pneumatic double barrier pump (AODD) has become an ideal choice for many engineering applications because of its safe and effective pumping performance. Although the AODD pump is simple to operate, there are many models available for this pump. It is also very important to choose the AODD pump model that is suitable for you.

What factors need to be considered when choosing AODD pump?

1 Chemical compatibility

The first step to confirm the AODD pump type is to ensure that the liquid you want to pump is chemically compatible with the pump data. In other words, the pumping data should be driven by the chemical compatibility of the pump. If the material you are pumping is chemically incompatible with the structure (metal and non-metal) or elastic data of your pump, your pump may suffer premature damage, corrosion or other protection problems that may be unsafe.

2 Flow

After understanding the compatibility of your liquid and AODD pump information, the next step should be to consider the flow. Your flow requirements (in gallons per minute) will help you confirm the size of the pump you need.

3 Loss of conflict

Another factor you must consider when selecting the pump is conflict loss. Because of the interaction between the inner wall of the pipeline and the pumped liquid, the collision loss occurred, resulting in the pressure drop at the end of the pipeline.

In terms of pressure, the maximum pressure of AODD pump is 125 psi. Before selecting the pump, please check all factors (in liquid feet) that lead to conflict loss to ensure that the maximum pressure does not exceed 125 psi. These factors include the number of elbows, valves, pipe size and pipe length, as well as liquid density, viscosity and other characteristics. After collecting this information and calculating the conflict loss, check it with the performance curve of the pump you are considering to ensure that it is within the scale. Please remember that if your pump runs very fast, you may want to consider upgrading the size of the pump to improve the life of the pump parts.

4 Consideration of specific market segments

In addition to chemical resistance, flow and conflict loss, you may also need to consider some specific market segment factors to help you determine what type of pump is required for the next project. The following is a list of several market factors that can help you reduce the size of your decision plan.

In addition to the standard resolution planning process and specific market factors described above, cost is also a factor to be considered when choosing AODD pumps. That is to say, it is the most economical and affordable to carefully select the appropriate pump for your application; Otherwise, your protection team may have to spend rated time and effort to repair an unmatched pump.
