### How to read the performance curve of an AODD pump.

**Question:** How do you read the performance curve of an AODD pump?

**Answer:**.

When looking at the performance curve of an Air-Operated Double Diaphragm (AODD) pump, there are a few key aspects to pay attention to in order to understand the pump's capabilities.

1. **Flow Rate:** The x-axis of the curve represents the flow rate of the pump, usually in gallons per minute (GPM). This shows how much liquid the pump can move at different operating pressures.

2. **Head Pressure:** The y-axis of the curve represents the head pressure, which is the maximum height that the pump can lift liquid. This is typically measured in feet or meters.

3. **Operating Range:** The curve will typically show a range of flow rates and head pressures where the pump operates efficiently. This is the area under the curve where the pump will perform optimally.

4. **Efficiency:** The performance curve can also give an indication of the pump's efficiency at different operating points. The steeper the curve, the higher the efficiency of the pump.

5. **Operating Limits:** It's important to note the limits of the pump's performance on the curve. Operating the pump outside of these limits can lead to decreased efficiency, increased wear and tear, and potential damage to the pump.

By understanding these aspects of the performance curve, users can select the right AODD pump for their application and operate it within its optimal range to ensure reliable and efficient performance.
