Learn how to calculate pump efficiency fast

Calculating and comparing energy consumption can be time consuming. But at Grundfos Product Center, you can quickly calculate a pump’s energy efficiency by using a life-cycle cost (LCC) evaluation criteria - and choose the most energy efficient pump for your project.

Step 1: Define your application requirements

To find the most-energy-efficient pump for your needs, select the application area and application that concerns you. Set your flow and head. Click "size product".

Step 2: Evaluate and compare pumps

Select parameters for evaluation, such as energy consumption. A selection of products will appear, listed in descending order according to best life cycle cost. Choose the one you're interested in to see the load profile. You can also see how much energy each pump will save you, as well as things like sizing, pump energy consumption, and CO2 emissions.

Step 3: Pump selection and documentation

You can select your preferred pump and export or print the relevant documentation. Or you can continue looking at and comparing other pumps to find the right balance of size with pump energy efficiency.
