In our previous posts we talked about how an air operated double diaphragm (AODD) pump works, and the advantages of installing this type of pump. In this blog post we’re looking specifically at the performance of the air operated double diaphragm pumps offered.
How can you know a pump is the right fit for your needs if you don’t know how it will perform under different circumstances? That’s where the performance curve comes in.
The Verderair Air Operated Diaphragm Pump Performance Curve. We offer a number of pumps in the Verderair range. In our case study, let’s look at one model in particular - the VA40. This pump can transport up to 397 litres per minute and produce up to 8.4 bars of pressure. This pump can be used to pump oils, solvents, chemicals, and lubricants, and other fluids.
Looking at the performance curve of a pump will tell you exactly what to expect from your equipment. It’s a great way to assess whether a pump will be the right fit for you.
The performance curve above is for the Verderair VA40, and shows how much air pressure is required to pump a specific volume of liquid (there are correction charts available for viscous fluids). It looks complicated; however, with a little help it’s easy to get a hang of - we’ll show you!
Let’s break down everything on the graph:
The performance curve allows you to calculate the air pressure required to move a specific volume of fluid. For example:
The Power of Performance CurvesWith this knowledge in hand, you can use any performance chart to work out how your pump should perform under specific circumstances.
