Grundfos Hydro Multi-E Pressure Boosting System
The Grundfos Hydro Multi-E is an intelligent pressure boosting system featuring built-in controls and full system redundancy without a conventional control unit. In this innovative solution, control lies within the pumps themselves, which communicate with each other to deliver reliable water pressure. Since each pump can function as the controlling unit, there is complete redundancy if a sensor or pump should fail. Together with Grundfos GO remote monitoring, the Hydro Multi-E presents a highly reliable and versatile booster solution for commercial and residential applications.
As an authorized Grundfos Water Pump Dealer in Dubai, we supply the complete Hydro Multi-E range with genuine warranty and technical support across the UAE.

Key Features & Benefits
High-Efficiency IE5 Motors
Motors used in the Hydro Multi-E range meet IE5 ultra-premium efficiency standards, delivering maximum energy savings and lowest operating costs. IE5 represents the highest motor efficiency class available, exceeding IE4 requirements by approximately 20%.
Multi-Master System Control Redundancy
If a sensor or master pump should fail, the next pump with a sensor automatically takes over as the controlling unit. This unique feature provides:
| Benefit | Description |
|---|---|
| No Breakdowns | Continuous operation despite component failure |
| Increased Uptime | Automatic failover with no manual intervention |
| Smooth Operation | Seamless transition between master pumps |
| No External Controls | All settings directly from the pump |
Proportional Pressure Control
Proportional pressure technology reduces friction losses in the pipe system, providing:
- Lower operation costs
- Less water leakage
- Greater comfort for end-users
- Reduced energy consumption
Soft Pressure Build-Up
The pump slowly fills the pipes on startup before ramping up speed to reach the setpoint. This intelligent startup sequence:
- Protects against water hammer
- Prevents pipe damage
- Reduces water leakage
- Minimizes startup noise
Communication Interfaces
Integrate fully into existing BMS or SCADA systems using Grundfos CIM interfaces, which enable:
| Capability | Benefit |
|---|---|
| Open Networks | Data communication via interoperable protocols |
| Complete Monitoring | Full process monitoring and control |
| Single Solution | One system for all monitoring needs |
| Increased Reliability | Comprehensive system oversight |
Remote Monitoring with Grundfos GO
Grundfos GO is a comprehensive platform for mobile pump control and pump selection. Monitor directly from your smartphone:
- Duty points
- Operating hours
- Power consumption
- Speed
- Temperature
