Triple Variable Speed Booster Set 10-3 – 375L/Min @ 4.5 Bar

The NT Cloke triple variable speed booster set is designed to maintain consistent water pressure in buildings where the incoming mains supply is insufficient or demand varies throughout the day.

Delivering up to 375 litres per minute at 4.5 bar, this system is ideal for commercial buildings, residential developments, and facilities requiring stable water pressure across multiple outlets.

Each unit is built using high-quality horizontal multistage pumps, combined with motor-mounted variable speed inverters that automatically adjust performance based on system demand. This ensures consistent pressure, improved energy efficiency, and reduced mechanical wear.

Supplied as a complete packaged system, the booster set includes pumps, manifolds, valves, pressure vessels, sensors, and control components, all pre-assembled and tested prior to dispatch for straightforward installation on site.
