Product Overview
Commercial laundry operations and high-volume wash bays utilize the Grundfos Hydro Multi-E 3 x CRNE 20-1 Three Phase 3 x 1.5kW Variable Speed 304ss Booster Pump Set with 24L Tank for continuous water delivery. Three Grundfos CRNE 20-1 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 99752347 provides the complete tested package in a single order line.
Under peak simultaneous facility draw, the skid maintains volumetric flow up to 1750 L/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 20 metres of head. Multi-Master autonomous inverter technology enables each pump to take lead control dynamically, providing complete hardware redundancy without requiring a separate central control cabinet.
The mechanical package is anchored to an ultra-sturdy, laser-cut mounting baseplate. The set is fully pre-plumbed with two 100 mm manifold connections, dedicated isolation valves, and integrated non-return valves on each discharge line. It connects to a 3 x 380-415 V supply at 50 / 60 Hz with combined rated current of 9.3 A (3 x 3.1 A per pump). A 24L diaphragm pressure tank absorbs initial draw-offs and line hammer, while IP55 enclosure protection and a 16 bar pressure rating ensure long-term mechanical reliability. Liquid-temperature suitability is 5°C to 60°C for all standard clean water booster duties.
A standard choice for regional council amenities, public libraries, and civic buildings. Integrating variable speed electronic control eliminates water hammer, extends mechanical life, and lowers lifecycle energy consumption compared to fixed-speed boosting systems.
