Product Overview
Commercial food and beverage production facilities maintain dependable wash-down pressure with the Grundfos Hydro Multi-E 3 x CRNE 15-8 Three Phase 3 x 7.5kW Variable Speed 304ss Booster Pump Set with 24L Tank. Three Grundfos CRNE 15-8 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 99752341 provides the complete tested package in a single order line.
Designed for expanding commercial tenancies, maximum system discharge reaches 1400 L/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 160 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.
For simplified plant room installation, the skid incorporates a heavy-duty base frame. 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 44.9 A (3 x 15 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.
Engineered for industrial manufacturing plants, chemical processing sites, and warehouses. Integrating variable speed electronic control eliminates water hammer, extends mechanical life, and lowers lifecycle energy consumption compared to fixed-speed boosting systems.
