Lowara Resvari Plus D 750 5-3 Variable Speed Booster Set 240V

Part Number: 135G01062

The Lowara Resvari Plus D 750 5-3 is a compact, dual-pump variable speed booster set engineered to provide reliable, energy-efficient water pressure boosting for domestic, light commercial, and washdown applications. Featuring a 750-litre Category 5 break tank, twin Lowara SCUBA submersible pumps, and integrated variable speed control, the system delivers consistent pressure while significantly reducing energy consumption.

Designed with installation flexibility in mind, the Resvari Plus D has a footprint comparable to a standard washing machine, allowing it to pass through conventional doorways and fit into restricted plant room spaces without disassembly. The dual-pump arrangement can operate in either Duty/Assist or Duty/Standby mode, providing greater performance during peak demand and built-in redundancy for enhanced system reliability.

Powered by the latest generation Lowara SCUBA multistage submersible pumps, the Resvari Plus D can achieve energy savings of up to 70% when compared to traditional fixed-speed booster systems.
