Product Overview
Multi-storey residential developments and apartment buildings achieve balanced riser pressure with the Grundfos Hydro Multi-E 3 x CRNE 15-2 Three Phase 3 x 2.2kW Variable Speed 304ss Booster Pump Set with 24L Tank. Three Grundfos CRNE 15-2 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 99752331 provides the complete tested package in a single order line.
Operating across its calibrated hydraulic envelope, the set achieves flow rates up to 1400 L/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 41 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.
Built for long-term plant room durability, the pumps rest on a corrosion-resistant base. 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 13.3 A (3 x 4.4 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.
Designed for secondary school campuses, university student hostels, and sports pavilions. Integrating variable speed electronic control eliminates water hammer, extends mechanical life, and lowers lifecycle energy consumption compared to fixed-speed boosting systems.
