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, twin-pump variable speed booster set designed to deliver outstanding water pressure performance for domestic, light commercial and washdown applications. Combining a 750-litre Category 5 break tank, dual Lowara SCUBA submersible pumps and intelligent variable speed control, the system provides reliable, energy-efficient boosting where a constant water supply and pressure are critical.

Powered by the latest generation Lowara SCUBA multistage submersible pumps, the Resvari Plus D delivers high performance while achieving energy savings of up to 70% compared to traditional fixed-speed booster systems. The intelligent control system automatically adjusts pump speed to match demand, ensuring consistent pressure and reduced operating costs.

Its dual-pump configuration can operate in either Duty/Assist or Duty/Standby mode, providing enhanced performance during peak demand and built-in redundancy for maximum reliability.

With a footprint comparable to a standard washing machine, the Resvari Plus D can easily pass through standard doorways and fit into restricted plant rooms and service areas without requiring disassembly.
