The surprising truth about pumps

  • You cannot go through a day without using pumps
    Pumps are involved in all kinds of processes and everyday practices. Taking a shower, drinking a cup of coffee, cooling off production equipment, ensuring the right temperature in office buildings, and transporting wastewater to sewage plants. All of these routines require pumps.

  • 2 out of 3 pumps are wasting energy [3]
    In two thirds of pumps and pump systems currently installed, it is possible to save up to 60% energy by switching to pumps with high-efficiency motors and variable frequency drives.

  • Buildings today account for 40% of the world’s energy use [5]
    This means that the resulting carbon emissions are greater than those from flights, trains, busses and cars combined. By optimising current pump installations in buildings this number can be significantly reduced.

  • Most pumps waste energy 95% of the time
    In many pump installations, the motors run at top speed, regardless of actual requirements. This means the pumps are needlessly inefficient. In fact, most pump motors only need to run at full speed for 5% of the time.
