Vertical Twin Variable Speed Booster Set – 170L/Min @ 8.0 Bar

The NT Cloke vertical twin variable speed booster set is designed for applications where strong, consistent water pressure is required across multiple levels.

Delivering up to 170 litres per minute at 8.0 bar, this system is ideal for multi-storey buildings, commercial properties, and installations where higher pressure is needed without stepping into extreme high-pressure systems.

Featuring vertical multistage pumps, the unit offers a compact footprint while improving access for servicing and maintenance. This design is often preferred by engineers and consultants, particularly in installations where uptime and efficiency 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.
