The Grundfos Hydro Multi-S is a complete pressure boosting system designed to provide reliable and consistent water pressure for commercial buildings, hotels, schools, residential developments, irrigation systems, and industrial facilities.
Supplied as a factory-assembled and tested package, the Hydro Multi-S combines multiple Grundfos pumps, intelligent controls, manifolds, valves, and protection devices into a compact booster solution that simplifies installation and operation. The system is designed specifically for boosting clean water in applications where water demand varies throughout the day.
What is Grundfos Hydro Multi-S?
The Grundfos Hydro Multi-S is a cascade-controlled pressure booster system consisting of two or three identical Grundfos pumps connected in parallel on a common base frame.
Depending on the application, the system may be supplied with:
- Grundfos CM Pumps
- Grundfos CMV Pumps
- Grundfos CR Pumps
The booster package includes an integrated control cabinet, pressure switches, non-return valves, isolating valves, manifolds, and other essential components required for operation.
How Grundfos Hydro Multi-S Works
The Hydro Multi-S automatically starts and stops pumps according to system demand.
When water consumption increases, additional pumps are brought online to maintain the required pressure. As demand decreases, pumps are switched off automatically to improve efficiency and reduce wear.
This cascade operation ensures:
- Stable water pressure
- Reliable system performance
- Reduced operating costs
- Improved pump lifespan
- Automatic response to varying demand
