Did you know that switching from a valve-based system to distributed pumps can save energy significantly?
Most chilled water systems use large centralised pumps and chillers controlled by valves. These valves waste loads of energy and make it difficult and time-consuming to balance the system correctly. Distributed Pumping systems for commercial buildings is a paradigm shift towards decentralised pumps that can save energy significantly and create a more consistent, comfortable climate throughout the building.
54% energy savings
Grundfos Distributed Pumping helped Ngee Ann, a large university building in Singapore, increase Delta T by 28% and reduce total pump energy by 54% – all while providing optimal comfort for building users.

How decentralised pumping saves energy
Distributed Pumping solutions replace centralised pumps and energy-consuming balancing and control valves with intelligent pumps placed on each floor of the building. This means the new system is equipped with components that generate pressure only when and where needed. The result is substantial energy savings and a more comfortable indoor climate.
How to increase comfort and improve Delta T
Inadequate commissioning leads to poorly balanced systems and excessive energy use. Replacing valves with pumps ensures optimal pressure and flow to each terminal unit at all times. So, you can increase comfort and improve Delta T. Get a great introduction to how Grundfos Distributed Pumping works in this video.

Training for commercial buildings
Want to learn more about Distributed Pumping in commercial buildings? Grundfos Ecademy offers the following training modules to support the execution of your project:
- How Grundfos Distributed Pumping works and what benefits it delivers
- The benefits of auto-balancing and how distributed pumps deliver the right flow and pressure
- How distributed pumps improve performance of HVAC systems without compromising reliability and end-user comfort
Distributed pumping can be applied to existing chilled water systems that need retrofitting or to new commercial buildings planned with chilled water air conditioning. It can also be applied in decentralised chilled water systems. Dig into the technical details of these specific applications and more in our distributed pumping white paper.
Beyond total energy savings and improved comfort, Grundfos Distributed Pumping offers easy commissioning, easy integration and improved chiller performance. Get an overview of all the benefits of Distributed Pumping and compare our system to a traditional valve-based system in our brochure.
