Finding a pump to fit your duty points and application can be time consuming. But the pump sizing tool helps you find the information you need fast – from application through to installation.

Enter your duty point in the pump sizing software and choose to size by application. Then select parameter for evaluation such as energy consumption and click 'start sizing'. 

Step 2: Evaluate and compare compliant pumps

Evaluate and compare pumps in the results list. The first pump is the ideal choice based on your sizing criteria and life cycle cost.

Step 3: Choose your desired product

Choose a specific pump to review in-depth pump information. Select the print option if you would like to make a PDF of the pump and print the relevant data you need, such as sizing results, curve, duty points, installation and pump dimensions.
