Wilo Isar BOOST5-E-3-2G: efficient and silent pressurization
The Wilo Isar BOOST5-E-3-2G is an automatic and self-priming water pressure boosting pump, designed to ensure constant water supply in domestic and residential settings. Thanks to its horizontal multistage construction, it offers high hydraulic efficiency and extremely silent operation, ideal for homes, gardens, and rainwater harvesting systems.
The Plug & Pump system allows for quick and uncomplicated installation: just connect it, set the desired pressure via the integrated LED display, and the pump is ready to use.
Automatic regulation and energy saving
Equipped with an integrated frequency converter, the Isar BOOST5-E-3-2G automatically modulates the motor speed according to water demand, maintaining constant pressure and minimizing electrical consumption.
The electronic regulation ensures stable operation even in case of flow variations, avoiding annoying pressure fluctuations. The start-up is progressive (soft start), to protect both the pump and the system from water hammer and mechanical stress.
Total safety and protection
Wilo has integrated numerous electronic safety systems into the BOOST5-E-3-2G, ensuring reliability and long life:
- Dry-running protection
- Overpressure protection

- Overcurrent and voltage variation protection (over/under)
These functions protect the device and ensure service continuity even in difficult conditions.
Compact design and ease of use
The machine body features a modern and compact structure, easily integrable into any technical or domestic environment.
The backlit LED display with control buttons allows real-time monitoring of pressure and operational status, making use simple and intuitive. Thanks to the integrated silencers, the pump operates at an extremely low noise level, ensuring optimal acoustic comfort.
Simplified installation and maintenance
The pump is supplied in a complete version with cable and plug, ready to use. The self-priming system allows for quick installation without the need for additional components. The package includes assembly, use, and maintenance instructions, for safe and immediate product management.
