Trebles - Domestic/Residential - 5050-5HM07S-FS/3 Cold Water Booster Set - 400V - Three Phase - 83 Ltr/min.

These Domestic/Residential single-pump cold water booster sets are intended for installations where incoming mains pressure is not sufficient. The package provides a compact, uncomplicated way to raise pressure without adding unnecessary complexity.

The pump sits directly on top of the expansion vessel, removing the need for a separate baseplate. That reduces both cost and overall weight while still giving the unit a solid, secure assembly, and it also makes handling on site easier where pallet trucks or trolleys are not practical.

Once commissioned, pressure is monitored by either a pressure switch or, on variable-speed versions, a transducer. If an outlet opens and the pressure drops, the booster starts automatically and maintains the selected set point. When demand stops, the unit stops as well, so it only runs when required and avoids unnecessary energy use.

The Domestic/Residential range uses modern e-HM stainless steel pumps with IE3 motors built to EN standards, providing reliable day-to-day operation with good performance and user comfort.
