Vertical Twin Variable Speed Booster Set – 320L/Min @ 6.5 Bar

The NT Cloke vertical twin variable speed booster set is engineered for high-demand environments where both strong pressure and high flow are required, while also maximising plantroom space and accessibility.

Delivering up to 320 litres per minute at 6.5 bar, this system is ideal for commercial buildings, large residential developments, and applications where maintaining consistent water pressure is critical.

Unlike horizontal systems, this unit uses vertical multistage pumps, offering a more compact footprint and improved access for servicing and maintenance. This makes it a preferred choice for engineers and consultants, particularly in installations where uptime is essential and routine maintenance must be carried out efficiently.

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 features dry run protection with automatic shutdown and restart functionality to safeguard the pumps.
