Product Overview
Industrial manufacturing plants and processing facilities specify the Grundfos Hydro Multi-E 3 x CRNE 15-5 Three Phase 3 x 5.5kW Variable Speed 304ss Booster Pump Set with 24L Tank to sustain steady water distribution. Three Grundfos CRNE 15-5 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 99752338 provides the complete tested package in a single order line.
Hydraulic performance is verified to sustain peak volumetric output up to 1400 L/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 102 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 turnkey package is built upon an integrated stainless steel structural 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 32.9 A (3 x 11 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.
Proven across aquatic centres, commercial fitness gyms, and public sports grandstands. Integrating variable speed electronic control eliminates water hammer, extends mechanical life, and lowers lifecycle energy consumption compared to fixed-speed boosting systems.
