Product Overview
Sports stadiums and aquatic centre change facilities install the high-capacity Grundfos Hydro Multi-E 3 x CRNE 20-2 Three Phase 3 x 3kW Variable Speed 304ss Booster Pump Set with 24L Tank. Three Grundfos CRNE 20-2 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 99752363 provides the complete tested package in a single order line.
Capable of answering sudden demand surges, the unit supplies bulk water flow up to 1750 L/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 42 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 self-contained booster skid is constructed on a torsionally rigid mounting platform. 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 18.6 A (3 x 6.2 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.
Specified for airport terminal concourses, railway stations, and bus transit interchanges. Integrating variable speed electronic control eliminates water hammer, extends mechanical life, and lowers lifecycle energy consumption compared to fixed-speed boosting systems.
