How to read an air-operated diaphragm pump curve

In this short video, users will learn how to read an air operated diaphragm pump (AOD) curve.

These graphs describe the relationship between the pressure/flow of the liquid being pumped and the pressure/flow of the compressed air required for pumping.

If you have an AOD pump, then this video will teach you how to determine how much air pressure and air flow you will need to operate your pump at a specific duty point (described in terms of the liquid flow rate and discharge pressure of the pump).

Alternatively, given the air supply pressure and process fluid flow rate, the information allows you to determine the airflow and liquid discharge pressure from the pump described.

The video is concise and straightforward, outlining the important features of the AOD pump curve and explaining the information it contains with colour-coded graphics and easy to understand narrative.

If you already have experience reading this type of graph, this video will refresh your memory, if not, then viewing the video will make it easy to interpret the curves found on an AOD pump performance graph.

Additionally, the video explains how to interpolate between the curves in case your duty point does not fall exactly on one of the predetermined curves. This information is specific for a given pump and allows the customer to determine whether the pump will be adequately sized for their use.
