Product Overview
Managing peak morning water demand across multi-tier plumbing risers is handled effortlessly by the Grundfos Hydro Multi-E 3 x CRNE45-1 Three Phase 3 x 5.5kW Variable Speed 304ss Booster Pump Set with 24L Tank. Three Grundfos CRNE45-1 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 93368418 provides the complete tested package in a single order line.
The interconnected hydraulic stages maintain continuous water delivery up to 3500 L/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 38.6 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.
All mechanical components are securely arranged on an electro-polished base frame. The set is fully pre-plumbed with two 200 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 29.9 A (3 x 10 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 convention halls, exhibition pavilions, and multipurpose event spaces. Integrating variable speed electronic control eliminates water hammer, extends mechanical life, and lowers lifecycle energy consumption compared to fixed-speed boosting systems.
