Today much of the energy consumed by pumps and pump motors in particular goes to waste. This is because most pumps currently installed are larger than necessary and they run continuously at their top speed regardless of actual requirements. It's easy to understand why it's unnecessary for a pump to run at full speed during the times when a business is closed, and yet most do. In reality most pump motors only have to run at their full speed 5% of the time[1]. This is true for all kinds of pumps: in commercial buildings, industrial applications, public buildings and water utilities. This means there are major opportunities for energy savings by utilizing a more efficient pump technology. One that is more intuitive, and allows for speed adjustment, depending on how much energy it needs to use.


These pump solutions already exist today, and although the initial cost to make the switch to more efficient pumps may seems unnecessary, the energy savings are immediate, and the payback time can be less than 2 years.


Even though pumps play such a tremendous role in the way we live in the modern world, they are largely overlooked. In fact, most people have no idea what a pump does, or where you would find one in their business. Pumps have somehow been overlooked in the raging debate about energy efficiency, carbon footprints and corporate social responsibility, because they don't have the same dramatic impact as other energy saving sources. And yet, they represent a solution, which is viable to everyone. And the savings are immediate.

One of the first things you can do towards a more energy efficient pump system is to collect some basic information about your company's current system and its annual life cycle costs.

1. Contact your chief operating officer (COO)

  • The COO will know:
    Who is in charge of the pump installations?
    What is your annual electricity consumption?
    What share of consumption do pumps account for?
  • And if possible
    How has electricity consumption of pumps developed over the last five years?

2. Then you ask the following:
    How many pumps and motors are installed?
    How old are the pumps?
    What types of pumps are installed?
    What is the annual volume of water pumped?
3. Create a list of all pumps and note where they are installed.

4. Call your local Grundfos energy efficiency expert
A Grundfos energy expert is extremely specialised and part of a "Pump Audit" team. The Pump Audit team can calculate your company's potential savings in terms of CO2 and operating costs.

Following these four quick steps will help you decide whether a pump system overhaul would make sound environmental, and business sense for your company.
