Vertical Twin Variable Speed Booster Set – 170L/Min @ 11 Bar

The NT Cloke vertical twin variable speed booster set is engineered for demanding applications where very high pressure is required alongside consistent system performance.

Delivering up to 170 litres per minute at 11 bar, this system is ideal for high-rise buildings, multi-storey developments, and installations where maintaining strong water pressure across multiple levels is essential.

Featuring vertical multistage pumps, this system offers a compact footprint while providing improved access for servicing and maintenance. This makes it a preferred choice for engineers and consultants, particularly in environments where reliability and uptime 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.
