The Vega BWD5-40 combines a 1.2 kW permanent-magnet motor with variable-speed pressure control for clean-water supply systems. It adjusts pump speed as demand changes to maintain the selected pressure, making it a practical option for tank-fed homes, buildings and irrigation systems sized to its working duty.
Key features

✓ Maintains a selected pressure as water demand changes.
✓ Matches pump speed to demand instead of continuously running at full speed.
✓ Combines the pump and VSD controls in one assembly.

Suitable applications
Installation and what is included
This listing is for one Vega BWD5-40 booster pump assembly with integrated VSD control. Prime the pump before operation and provide a suitable clean-water suction supply. Have the electrical connection, earthing and system commissioning completed by a qualified installer. Install the pump in a suitably ventilated, protected location.
A twin-pump system requires a second compatible pump and the appropriate linking connections and pipework. Size the installation to the selected working pressure and consult the operating manual before commissioning.
