2″ Vertical Triple Variable Speed Booster Set – 480L/Min @ 6.5 Bar

The NT Cloke vertical triple variable speed booster set is engineered for demanding applications where high water flow and strong, consistent pressure are required across large systems.

Delivering up to 480 litres per minute at 6.5 bar, this system is ideal for commercial buildings, large residential developments, and installations where maintaining reliable pressure across multiple outlets is essential.

Featuring vertical multistage pumps, the system offers a compact footprint while improving access for servicing and maintenance. This design is widely preferred by engineers and consultants, particularly in environments where uptime and efficient servicing are critical.

Built with WRAS-approved stainless steel components, the system uses advanced variable speed inverter control to automatically adjust performance based on demand. This ensures stable pressure, improved energy efficiency, and reduced wear on system components.

Supplied as a fully assembled and pre-tested package, the booster set includes pumps, pressure vessel, controls, and fittings for straightforward installation.

In the event of water supply interruption, the system includes dry run protection with automatic shutdown and restart functionality to safeguard the pumps.
