Product Overview
Commercial high-rise towers and corporate office buildings specify the Grundfos Hydro Multi-E 3 x CRNE 15-1 Three Phase 3 x 1.5kW Variable Speed 304ss Booster Pump Set with 24L Tank for consistent multi-tier mains pressure. Three Grundfos CRNE 15-1 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 99752328 provides the complete tested package in a single order line.
Engineered for heavy continuous duty, the system yields flow rates up to 1400 L/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 21 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 physical assembly features a rigid, vibration-absorbing structural steel 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.
Suited to hospital surgical suites, medical treatment centres, and healthcare facilities. Integrating variable speed electronic control eliminates water hammer, extends mechanical life, and lowers lifecycle energy consumption compared to fixed-speed boosting systems.
